The same threads come up week after week asking about how to go about using a LCD monitor with a console, so I figured that I might as well write a quick guide to how to get everything working. If you find any typos or what you think is wrong info, then let me know and I'll take a look.
1. Why would I want to use a LCD monitor as a HDTV?
2. Can I get 1080p/1080i/720p on my monitor?
3. What's this 16:10 and 16:9 business?
4. What connections do I need for my console?
5. Wait a minute, my monitor doesn't have speakers!
1. Why would I want to use a LCD monitor as a HDTV?
The main reason is cost. It's much more affordable, for students especially, and can cost as little as $250 or even less to get the HD experience out of your console. Another reason is that maybe you already have a decent monitor with your computer, so why not get more out of it? A few months ago, I picked up a 24" monitor to use for my computer and 360. I get a much bigger workspace on my computer and I get to have full 1080p gaming, two birds with one stone.
The compromise you have to make with using a monitor instead of a HDTV is that you probably want to put it on your desk instead of in a living room situation. LCD monitors have smaller pixels than HDTV, so to see the details, it's best to sit at your desk and view it from a regular monitor viewing distance. From this distance, your eyes see a relatively large image, so it's almost comparable to viewing a HDTV in a living room situation.
2. Can I get 1080p/1080i/720p on my monitor?
The main widescreen resolutions available in LCD monitors right now are 1440x900, 1680x1050, 1920x1200, and 2560x1600. 1440x900 is primarily used in 19" widescreen monitors and rarely in 17"s. 1680x1050 is used in 20"s and 22"s. 1920x1200 is used in 24"s primarily and some 26"s and 27"s. Lastly 2560x1600 is used in 30"s and insanely large monitors that we'll ignore in this thread, simply because they're so expensive that you might as well buy a HDTV.
1080p and 720p use 1920x1080 and 1280x720 resolutions, respectively. In the case of 1080i, it's converted to 1920x1080 or 1280x720 in fixed resolution HDTV's anyways, so I'll just skip over it. As you can see, 1080p and 720p resolutions don't exactly match up with the LCD monitor resolutions. This is due to the difference in aspect ratios (16:10 vs 16:9).
Essentially, all of the monitors can display at least 720p. With most monitors, the 720p signal will be stretched to fit the screen. Some more expensive monitors have the option to not stretch the the signal to fit the screen. The option is called 1:1 pixel mapping. The monitor displays exactly 1280x720 pixels in the middle of the screen and all the extra pixels on the side are blacked out. This ensures a pixel perfect image.
1080p is a little harder to get. There are some 22" monitors that will "accept" 1080p signals and fit the image to the 1680x1050 resolution. This gives you a better image than 720p, but you're still not getting a pixel perfect 1080p image. 24"s and larger displays have the resolution needed for full 1080p, but not all 24"s will accept 1080p signals, this will be covered in a later section.
Update: For non-widescreen monitors, the 360 can output 1280x1024 and 1024x768 over VGA. While I can't remember for sure, some scenes/games will be widescreen with black bars above and below the image, and others will use a non-wide image upscaled to fit your non-widescreen monitor. Either way, 1280x1024 and 1024x768 are still better than standard definition television in terms of resolution, but they're not a "standard" HD resolution such as 720p, 1080i, or 1080p.
3. What's this 16:10 and 16:9 business?
16:9 is the aspect ratio of high definition video signals. It means that for every 9 units tall, the signal is 16 units wide. LCD monitors are a bit different, they are 16:10. This means that LCD monitors are a bit bigger in height than HD signals.
With most monitors, the HD video signal will just be stretched to fit the full screen, so your image will be slightly stretched vertically. How bad is it? Well in numbers, it's 11% taller than it should be. Some people do not mind it that much considering the amount of money they're saving with a monitor setup.
Some monitors have 1:1 pixel mapping and aspect display options. 1:1 pixel mapping is explained in the above section. It allows a video signal to be displayed pixel by pixel in the middle of the screen with black bars all around to fill the extra space. Another display option is "aspect", it stretches the video signal to fit the screen as much as possible while keeping the aspect ratio. In the case of HD video signals, there will be black bars above and below the image, so that there's no vertical stretching. These two options often come together, it's hard to find a monitor with one but not the other. They're found more often in more expensive monitors.
4. What connections do I need for my console?
For the Xbox 360 (non-elite), you have the option for using VGA or component. VGA is simple enough to find on all monitors, so that's not a big deal. The VGA resolutions currently offered by the 360 are 640x480, 848x480, 1024x768, 1280x720, 1280x768, 1280x1024, 1360x768, and 1920x1080. 1360x768 is the best option if you have a 16:10 aspect ratio monitor that does not have 1:1 pixel mapping or aspect display mode. It is very close to being 16:10. Another option you can use is 1280x1024 and set it to widescreen, only use this if your monitor can accept 1280x1024. This option outputs a 1280x1024 image, but it is a widescreen image squished into this 1280x1024 resolution. What your monitor will do is take this image and stretched it out to fit the screen. The result is pretty good, and it actually contains more pixels than 1360x768, so it -should- give a better image.
For the PS3 or a HDMI equipped Xbox 360, you need a DVI-D or HDMI input. These two are pretty much the same signal, but HDMI also has audio built in. DVI-D is quite common on monitors now, so if the monitor doesn't have HDMI, just use a HDMI to DVI-D adapter that can be found for a few dollars at Radioshack or computer stores. The DVI-D or HDMI input you use must also be HDCP compliant. If a monitor doesn't say it's HDCP compliant, then it's probably not.
If you need to use component cables (Wii, PS2, Xbox, etc), there are some monitors that offer component inputs, but there is only a handful of them, and they're generally more expensive. You can buy a component to VGA converter. You can find really cheap ones on the internet, but they're generally of horrible quality. The most popular one right now seems to be the X2VGA, it's designed to use with consoles. It will work with 1080p, 1080i, 720p, and 480p resolutions from your component cable. As a side note, not all component inputs will accept up to 1080p. Do some research on your monitor if you want to use component up to 1080p.
If you want to use composite cables or s-video, you'll have to find a monitor that has these inputs. There aren't many with these inputs. To be honest, I think you're better off using these consoles on your regular television instead. You'll probably get a better picture that way.
5. Wait a minute, my monitor doesn't have speakers!
There are quite a few options you have for sound. You can run it through an av receiver, run it to standalone computer speakers, or run it through your computer
If you have an av receiver near your console, you can actually run an optical cable or the red and white composite audio cables to it. Simple enough!
You can also buy cheap (or more expensive) standalone computer speakers. Make sure they have an aux input. These can be had for $20-$30. The Logitech X-140 is one of the cheap options. Some monitors also have built in speakers or speaker addons that you can purchase separately, but they would all have the same input.
What you need to complete the connection is a RCA to 1/8" stereo cable/adapter. It converts the red and white audio signals into a 1/8" miniplug. If the only cable you can find has two male plugs on the RCA end, then you can simply find two RCA gender changers or couplers or whatever they're called. Both the cable/adapter and the gender changers/couplers if you need them should total to less than $15 and can be found at stores like Radioshack. The Microsoft 360 VGA cables come with this exact cable, so that'll save you some money/time.
If you want to get surround sound, you need to find a 5.1 set of speakers that offers optical input (your console must offer optical output also, eg 360, PS3). Red/white composite audio cables only offer stereo sound.
If you already have speakers but they don't have aux input, then you can run the audio signal through your computer's sound card. You still need the RCA to 1/8" cable/adapter and possibly the gender changers/couplers described above. You run this cable into your computer's sound card, make sure the volume for your line-in signal is turned up, and you should be getting audio out of your computer's speakers. The downside to this is that you have to leave your computer on when you want sound.
And I think that's everything you need to know about setting up a LCD monitor to use with your consoles. This does not only apply to consoles, the same ideas can be used for cable boxes and HD programming as well. If you have any more questions, go ahead and ask, but I don't really want to rate your particular monitor. Hope it helps!
