Using a TV as a computer monitor

A regular TV may not serve well as the only computer monitor for your computing and video-entertainment needs

An issue that will crop up with home computing nowadays is whether to use a TV as the only display device for your computer as well as providing video entertainment.

This is an idea that tends to appeal to those of us who are living in small areas like college dorms or small apartments or simply have this kind of space as our own personal living space in a shared environment.

In this context, I am assuming that you are using the screen as part of a desktop computing setup whether by using a traditional desktop computer or by connecting your laptop computer to the display and having it serve as the primary display. I am not talking about running the display you want to use as part of a multiple-screen setup or for occasional group-viewing use.

There will be issues that will preclude this kind of use for a TV serving this role for your computer.

Pixel Density

An issue you will need to pay attention to is the pixel density your display device offers especially if you are intending to use it as your only display device for your computing and entertainment needs.

A 15” Full HD laptop would offer a pixel density of 141.2 pixels per inch while a 32” Full HD TV would work at 68.84 pixels per inch. Apple’s iPhones that implement the Retina screen would work at 326ppi while their MacBook Pro Retina screen would work at 227ppi.

Here. the display that works at something like 141.2 pixels per inch or more would make text or graphics look sharp and clear especially if you are working close to the screen. It may not matter if you are playing video games or viewing multimedia content at a “lean-back” distance.

Here, if you are buying a TV or monitor with a screen size of 27” or less, make sure you are looking for a model that uses Full HD (1080p) resolution. Larger screen sizes can be served through the use of a value-priced 32”-55” 4K UHDTV device.

Your computer’s display infrastructure needs to have an HDMI 2.0 output, preferably HDMI 2.0a for HDR10-capable displays. This may be fulfilled by most recent discrete GPUs and some recent Intel integrated graphics setups may also support this specification. If your computer or external graphics module uses a DisplayPort video output, you may need to use a DisplayPort to HDMI adaptor. Beware some of these devices may require the use of an active DisplayPort to HDMI adaptor.

Input Lag and Display Responsiveness

This is an issue that will affect gameplay where you are expected to respond quickly to the situation that is taking place in a game you are playing. It is more of concern when you are playing any fast-paced game.

The input lag problem is the time between when you do something with your game controller, keyboard or mouse and when the effect of that is painted on the screen. Then there will be issues where the screen doesn’t appear with the latest activity or isn’t quick enough to represent all of the activity including what your opponents are up to.

This is brought about due to most domestic TVs being equipped with a lot of video-processing circuity logic that deals with the incoming signal before it is painted on the screen. The time it takes may be just enough for dealing with video content but not interactive gaming content.

Some sets will offer a “gaming mode” to minimise lag times and this typically reduces the use of video-processing circuitry or optimises it for fast response. Also be aware that a significant number of large-screen TVs are appearing with features and graphics performance very similar to gaming-class computer monitors with this as a growing trend. This is due to the fact that games consoles and “gaming-rig” computers including Thunderbolt-3-equipped laptops connected to gaming-class external-graphics-module setups are connected to the large screen TV for impressive multiplayer game play.

In a lot of cases, most TVs wouldn’t work well as a sole display device, with this applying more towards small cheap HDTVs. But they can work well as a secondary screen or for large-screen group-viewing use.

What about purposing a computer monitor for TV use

You could purpose a computer monitor with built-in speakers as a TV by adding a set-top box or similar peripheral

Another approach would be to use a suitably-sized monitor as your TV set, especially if it is equipped with integrated speakers. In most cases, the monitor won’t have a remote control for “lean-back” viewing because you intend to use it with your computer.

You may come across a “TV monitor” which is a computer monitor that has an integrated TV tuner and is pitched for desktop use. These are available in countries with strong support for free-to-air TV like UK, Europe, Asia and Oceania. Typically they will have a Full HD screen with a size of 32” or smaller but have display electronics optimised for computer use.

On the other hand, your computer monitor would need to be equipped with a spare HDMI input that has HDCP support. Here, you use a set-top box or PVR that has an HDMI output to receive TV broadcasts.

If you subscribe to traditional pay TV, your pay-TV provider will lease you a set-top box or PVR as part of the service and this can work well if free-to-air TV is provided via the pay-TV platform. On the other hand, your local consumer-electronics store will have set-top boxes or PVRs that work with free-to-air TV and these units will display high-definition channels at their proper resolution.

A broadcast-LAN setup like SAT>IP can work with your computer if it is running the appropriate client software. As well some platforms like SAT>IP are supported by set-top boxes that connect to your monitor’s HDMI input. You may also find that some Internet-based set-top-box platforms will offer access to real-time video streaming through the broadcasters’ video-on-demand platforms or a similar application.

You may find that some games consoles like the XBox One will have a TV-tuner module supplied as a first-party or third-party option. Similarly, you may be able to use a USB-based TV-tuner module or a TV-tuner card as a way to purpose your computer for TV-viewing.

On the other hand, if you are just content with Netflix and similar online services, you can just get by with using the service’s Website and viewing the video content on the monitor in a full-screen arrangement. As well, AirPlay (facilitated with Apple TV) or Chromecast can work when it comes to “throwing” the video content from your smartphone or tablet to the monitor.

Conclusion

You will find that using one display for your computing and video entertainment needs may cut it for some applications but not for others like full-on gaming.

Gaming with a regular computer and the big screen in the lounge?

How To PC Game From The Comfort Of Your Couch | Gizmodo

An Alienware gaming laptop that bridges performance and portability

Gaming on the big-screen TV isn’t just restricted to the likes of the XBox One or the PlayStation 4 consoles. You can engage in these games using your PC especially if you are using a laptop or dare to bring the tower-style gaming rig in to your lounge area. This is more so as the regular computer platforms i.e. Windows, OS X (Macintosh) and Linux still maintain a strong level of open-frame software deployment and become more the areas to try out gaming ideas.

This is brought on by the increase in the number of portable computers that have performance-computing chops whether in the form of mobile workstations or gaming laptops is making this kind of gaming more real. The manufacturers see this as a valuable niche for people who value performance and portability for work or play.

This will apply to those of you who are at home or at a friend’s house because you could bring your gaming computer in to the living room or games room and play that game on the big screen from the comfort of your couch. Those of you who are staying at a college dorm (university residence hall) or similar location can use the big-screen TV in the common lounge area for playing that epic game on your gaming laptop.

What do you need?

TV and sound system

The TV or home-theatre system would need to have a spare HDMI connection for you to plug in another video peripheral.

Here, you are relying on HDMI as your audio and video connection and the equipment must be able to play the sound from an HDMI connection rather than just be a switcher. Recently-made home-theatre receivers will most likely be able to satisfy this requirement but beware of lower-end equipment that can’t achieve this goal.

If you are buying a newer large-screen TV and you expect a regular computer to be connected to it, you should look for sets that have a high refresh rate like what would be expected for most well-bred monitors. As well, if your gaming setup is of a temporary nature, I would recommend that the equipment concerned has an HDMI connector on the front panel for a home-theatre receiver or similar device or on the side edge of a TV so that it is easily accessible without you needing to shift the equipment out or grope around the back whenever you want to play games.

In the case of an HDMI connection on the side of a TV, a short HDMI extension cord can come in handy if you find the side connections difficult to gain access to.

The computer should have HDMI as a video output option and be capable of directing the sound through that output. This is to achieve the goal of one cable between the computer and the TV or home-theatre receiver rather than worrying about many cables, with this cable carrying a digital audio signal along with the high-resolution video signal.

When you set up the sound, make sure that you know what your equipment can handle at best. If you use a home-theatre system, make sure that you set the audio output for Dolby Digital 5.1 bitstream or a similar codec that your equipment handles so you can take advantage of games that implement surround sound.

As well, it may be worth paying attention to an article that I wrote about multiple sound devices in Windows. In this case, you have to make sure that the sound device you are using for your game is the “display audio” or “HDMI audio” device associated with the graphics infrastructure you are using. Here, it’s about preparing and passing the sound through the HDMI connection to the TV’s speakers or the home-theatre receiver in a manner these devices can handle.

Control devices

Games that require frequent interactive activity would benefit form a console-type controller if you are leaning back on the couch. There are some wireless controllers out there but you can use an XBox 360 or XBox One controller that works with Windows courtesy of an adaptor that is sold for “pennies worth” by Microsoft.

For that matter, XBox One controllers are now able to work directly with your Windows-based computer via USB and the newest XBox One wireless controllers including the XBox Adaptive Controller can work via Bluetooth. This means you don’t need to buy a Microsoft adaptor to link your controller to your computer as explained in this article about achieving this setup.

These Bluetooth keyboards also earn their keep on the couch when gaming in the lounge

If you are needing to use a keyboard or mouse, it may be preferable to use wireless peripherals so you avoid cable clutter. Personally I would prefer to use Bluetooth equipment because you only need to use one transceiver dongle across them all and if the computer has integrated Bluetooth, you don’t need to worry about any of these transceiver devices. Sometimes a wireless keyboard or mouse pitched at tablet use can work as a wireless keyboard for gaming use.

Network

It is preferable to have an Ethernet socket in the lounge area but this may not be a reality. For your home or a friend’s, you may find that setting up a HomePlug AV500 powerline-network segment may work well in these circumstances.

Some college dorms and similar places may have an Ethernet socket connected to the premises’ network and Internet service not far from the common lounge area  HomePlug AV500 or HomePlug AV2 may work well in using a no-new-wires setup to bring the connection closer. In some cases, this connection may be locked down for specific devices and uses and it doesn’t hurt asking the staff about whether the connection is a “general-use” connection or can be set up as such.

At a pinch, you would need to use Wi-Fi wireless and make sure you have a reliable Wi-Fi connection at your computer. Wi-Fi networks that use Web-based login can be tricky to use and may require you to keep the “login successful” Web page minimised while you play that online game.This is best done with a Web browser that doesn’t take up much memory space.

Similarly, if you are playing against multiple computers across a public network, it may be difficult to discover the opponents’ computers because these networks are most likely set up to provide client isolation.

Setup

There are some things you will need to be sure of when you are setting up for gaming in the living room or other lounge area.

One would be to use a rug to cover long cables that travel between the computer and the TV or home theatre so as to avoid the situation of people tripping over the cables. This is important for situations where the area between the couch and the TV equipment is part of a thoroughfare.

A tray-table or bed desk is also a good place to position your gaming laptop or to use as a mouse mat. On the other hand, you may want to use the coffee table for that same purpose. This is to assure stability. Even those “Stable Table” trays with integrated cushions can come in handy as a mouse mat.

As for online game managers, Steam is the only such platform that provides a “big-screen” mode courtesy of their “Big Picture” mode. This will allow you to manage it while viewing the display from a distance. But when you are actually playing the game, this may not be a problem. It is due to a default approach by many games using the whole of the screen as their display canvas.

Conclusion

Once you know that you can game on with the big-screen TV and your gaming rig or laptop computer, you could be able to add that bit extra to your solo or group gaming experience.

IKEA to push in to consumer electronics

Article

Ikea is positoned to dominate consumer electronics | Retail Computer Solutions

My Comments

IKEA, the Swedish homewares retail giant known for the assemble-it-yourself furniture, are now taking giant steps in to the world of consumer electronics. They have taken some small steps with TVs being sold in to some parts of the European market but want to take bolder steps with this class of product.

Could you be buying a TV or stereo from the same shop that you buy that build-it-yourself BILLY bookcase?

But they work on an “experience” driven model rather than the common method of retailing consumer electronics where products of a kind are grouped together. If you wander through the Showroom level of an IKEA store, you will pass through room layouts set up with complementing furniture, homewares and soft furnishings as if they are part of your home. For them, once they cut in to consumer electronics and home appliances, these layouts could be activated with the TVs, white-goods and other appliances so you could see the whole equation.

The problem that I see here is whether these will be baseline items such as TVs and video-peripherals not equipped with HDMI-CEC video-peripheral control or HDMI-ARC two-way sound paths or appliances that don’t have the full level of “smart-home” readiness like I am used to with goods sold in the discount stores. They could easily work better to look at what most products offered by the big names in their popular ranges offer in terms of functionality, efficiency and features and offer these at prices that better the big names.

I see this more as being interesting for IKEA and it may be interesting whether they even cut in to the home-network scene at all by offering network accessories.

The idea of a video peripheral enabling an existing TV was highlighted by Panasonic in the 1980s

What do I see of video peripherals like Blu-Ray players, Blu-Ray home-theatre systems and network video players with “smart-TV” capability is that they are able to enable an existing TV with the smart-TV functions. Examples of these functions included DLNA network media playback, client-side access to the popular online content services and even the ability to co-opt your TV in to service as a large-screen Skype videophone once you purchased an optional camera kit.

But I see Sony, Samsung, Panasonic and others who do this right following an example that was underscored through the 1980s. In the Panasonic “Flashback” blog post, they highlighted the abilities that their PV-1742 VHS Hi-Fi VCR offered when it comes to reproducing what was considered great sound from video movies in its day. This was to utilise the VHS Hi-Fi system for recording and playback of video content including playback of those videos you rented from the video store with the high-quality stereo sound.

But one feature highlighted here was to allow you to use its inbuilt stereo TV tuner to watch TV broadcasts with stereo sound playing through your hi-fi, describing it as “converting your TV in to a stereo TV”. What was being highlighted here was a TV enablement feature, in a similar way to how most video recorders released through its model year also offered other features like the ability to change channels with its remote control or provide access to extra TV content (UHF or in-the-clear cable broadcasts, more channel spaces, etc) due to what the VCR’s tuner offered or simply the use of a reliable electronic tuner even if your old TV implemented a mechanical tuner.

What I see of Panasonic touching on the capabilities of video recorders like the PV-1742 and its peers was for them to be simply a TV-enablement device like today’s well-bred Blu-Ray players.

Two-screen TV viewing a strong trend

The Future Of TV Is Two Screens, One Held Firmly In Your Hands | Fast Company

My Comments

There is something that is becoming a reality with TV. It is where our TV-viewing sessions are involving two screens – one large screen carrying the main video and one smaller screen that we are holding in our hands.

This has been brought about by the popularity of the tablet, laptop and smartphone which are serving the second-screen role.

Some of us may think it is just for checking email or the activities of our Facebook Friends or Twitter followers. But a fair bit of this activity is to do with the content itself.

For example, one could be using GetGlue, Fango or other TV-related social networks to find out who is watching this show and what others have to say about it. Similarly, one could be checking the show’s Website and looking at other information and commentary that exists there. These are activities that may not work well on the big screen.

Similarly, most big-screen applications cannot support multiple concurrent logins for social-network or similar uses; and they are typically require “pick’n’choose” or “SMS-style” text entry.

In the case of news, a good quote for this is that “the revolution doesn’t have to be televised”. Here, one could be checking other news resources to verify the veracity of a news story, which can be very difficult during election time. This is augmented through comment feeds and Tweet feeds that are set up during news events like the one I participated in during the UK parliamentary inquire in to the News Corporation phone hacking scandal where I was dropping Tweets in to the feed from a Fujitsu laptop that I was reviewing. Similarly the scoreboard apps that I have mentioned about previously could simply work as an always-live scoreboard display during a sporting event and some sports like cricket or racing may benefit from these apps further by displaying supplementary scores like track position or bowling scores.

Of course, the commercials as we know them will be hamstrung by the two-screen viewing experience. This is more so as the traditional goal of eyeballs at the screen during ad breaks is reduced more. Here one could be following up information on the second screen while the ads play on; as well as visiting the kitchen or bathroom or stoking up the log fire. But the information that one could be following up on can relate to what was in the TV program; or it could be to follow up on something that was advertised during that ad break or a previous ad break.

As I have noticed and observed, this concept of two-screen TV is hard to adjust to for some people, especially the older generation who are more interested in focusing directly on the screen. It may be us simply glancing down at that smartphone or tablet so we can know further what is going on with some events.

I see this as becoming an interesting chain of events as we integrate in to an online and highly-interactive media-consumption life.

OLED to become another display option for large TVs

Panasonic, Sony purportedly entering into OLED TV team-up, torrid love affair | Engadget

My Comments

If you have a Samsung or HTC smartphone, you will most likely be using a phone that is equipped with an OLED display. Similarly you may have seen this technology in use with some upmarket car stereos.

These displays work on a self-illuminating method in a similar vein to the legacy cathode-ray-tube screens, the fluorescent displays used on most consumer-electronics equipment and the plasma display screens used in some larger flatscreen TVs. This is compared to the common LCD display technology used in most display applications that requires a backlight for the display to work.

They are known to offer an advantage of improved contrast as well as improved power efficiency for portable devices. The monochrome variants have been used effectively as a low-power equivalent to the previously-mentioned fluorescent displays, thus providing the same display look on battery-operated equipment.

Sony had previously launched an OLED-based TV in the form of the XEL-1 but this set used a screen that was eqivalent in size to most desktop computer monitors yet was very expensive compared to its peers. Now Panasonic, Samsung and Sony are taking this further by implementing OLED display technology in larger TVs that are fit for group-viewing in lounge rooms or family rooms.

Panasonic and Sony are pooling technical know-how to allow the creation of the large-area OLED displays necessary for the creation of these sets at prices affordable for most people.

What I see about this is it could be an effort in creating a large vivid high-contrast self-illuminating display that doesn’t consume lots of energy and is affordable for most users.
