How's the picture quality if we use HDTV as a pc monitor via RGB? Unfortunately i don't have HDMI output in my graphic card.

Um...my bad. I think it's VGA or DVI not RGB. I don't remember much about the connection name.

Edit: Oh wait...this is my graphic card model. But i'm kinda nub here so i don't really understand. It did says about having HDTV technology or something like that but doesn't state about having any HDMI output. I can't check my graphic card since i'm at my college right now.

The 60hz versus 100Hz versus 120hz panel refresh rates would not make much of a difference to your naked eyes.

IMO, for gaming and fast motion video, the other important thing is the response time:
look for one that has 6ms response or less so that you don't see the ghost or motion blur.

When look for full HD (1080p @ 1920x1080 resolution), make sure it can really also support
the full 1920x1080 using the PC VGA/DVI port. A lot of cheapo manufacturers claim Full HD but when connected
to PC, the best resolution it can support is only 1366x768  this is only 720p or upscale to 1080i.
Some manufacturers cheat on buyers this way by not revealing what the tru resolution is when connected to a PC.

If possible, go to their demo room with your laptop and PC-VGA-DVI connector and try it out, and change the resolution. If you can read the text with the highest supported resolution (1920x1080), that means it is a good display. Of course, your laptop graphics card must also be capable of displaying this mode.

For colour and contrast, look for the deepest black with highest contrast ratio: at least 10000:1.
