VGA, XGA, definition and all that. What does it mean?

23-07-2004, 17:17

My dad has just purchased a 20" LCD television with a VGA display. He will only be using it to watch telly, mainly just through an aerial and sometimes via Freeview. My question is does the fact that it is only a VGA display actually matter? I mean will the picture be as good as a normal CRT television or should he have got one with an XGA display and is there a real noticable difference between the 2?

Thanks for your help.

The screen will have an input for a PC, which is what the VGA support will be. There are (AFAIK) no XGA displays. Since broadcast TV is lower resolution than the screen is, and it has to be stretched to fill the screen. This means the picture probably won't be as good as a conventional CRT screen but this will apply to all LCD/TFT screens.

Hope this helps

VGA - 640x480
SVGA - 800x600
XGA - 1024x768
SXGA - 1280x1024

Since broadcast television is only 720x576 for PAL, then I don't think it'll be a problem.

If you want to use a computer on it, it is not advisable as 640x480 is a very small resolution compared to those that you can get today.
