Bobo, seriously any monitor with a HDMI prort will work. I have done this since the PS3 came out and I am on my third monitor since then. The only issues are;
1. Sound - does it have built-in speaker? Those that do typically come with like 2 watts. Luckily many also come with an audio out jack.
2. Input ports. - Some come with 2 HDMI ports if you want to output both your desktop PC and PS3 with HDMI but this is rare. In my case I case I put the PS3 on HDMI and had the desktop on displayport which also carries sound.
3. Size - get the biggest one you can find. Hell get a TV!
