There's no reason a 22" monitor can't be 1920x1080, it just depends on how it was made. Most monitors are switching to 1920x1080 to be compatible with HDTV's. We will eventually have a resolution of 3840x2160 on larger monitors and HDTV's (i.e. 30" monitor or 100" HDTV).
PS3 at 1080p?
To be clear, there are TWO types of video signals:
1. PC video
2. TV video
Perhaps not the exact names. Anyway, TV signals are either 480i, 480p, 720p, 1080i or 1080p, whereas the computer signals are any resolution from 640x480 up. A 720p (1280x720) TV signal is in a different format from a computer 1280x720 signal.
My point is that older monitors support only the computer signals, whereas newer monitors have inputs for both.
Your monitor has an HDMI input which I assume is a "TV" input but it may not be.
I'm not certain, but I think the PS3 and XBOX360 require the TV signal input.
Your PS3 and monitor will probably work fine at 1920x1080. Just try it. If you can't get it working at all it's likely the HDMI input is not compatible with a TV signal in which case it only talks to computers.
I'm no expert, but I would assume that an HDMI input on any screen would be a TV input to avoid confusion. It's also possible that it supports BOTH computer and TV signals.
If your HDMI input is a TV input (or both TV and PC), it is compatible with any HDMI TV device such as a Cable box or DVD player. I have a splitter from Monoprice for HDMI so I can switch between my DVD player and TV box. It's manual and only a 2-switch but it was only $15.
Using 1920 x 1080 with TV Box and 1080p with the PS3, the results shows nice graphics but blurry effect.
Using 1080p with the PS3 along my monitor, the results shows better graphics than the first but it lacks sound capability.
Still using my 24 inch HDTV gave me the overall best.
Thanks for the reply. Problem solved
May be this can be a reference for 22 inch monitors
Should not be blurry.
My HDTV was blurry when I output a DIFFERENT resolution than my HDTV's default.
I don't own a PS3, but if no sound maybe there's a different audio selection in the PS3 setup?
Not all HDTV's and monitors are the same so you may need to experiment for best results (and read your manual).
My monitor (U2711) has an HDMI input but no speakers. It does have audio outputs though so my HDMI audio is converted inside the monitor from digital to analog for external speakers (also there is digital audio).
Keep in mind that TV's and Monitors increasingly have a mix of inputs that support Computer Video and TV Video. For example, Sony has a PC-HDMI input. That's the same as DVI-D + Digital Audio. It can accept all the screen resolutions from 640x480, 800x600... to 1920x1080.
