After years of reliable use my old CRT monitor died. So I bought a new LG 20 inch lcd:
1. The res/picture qulaity seems about same as my old CRT - I assume due to the following: a) I have res set at 1024x768 (the recommended 1680 x 1050 makes the font really small which I don't like); b) I am connected via VGA not DVI (no DVI slot on my computer). Does this seem right or is there another reason wht res is same as old CRT?
2. I found the screen a little bright so turned down the brightness setting from max (100) to around 75. When I did I found that the monitor produced an annoying hum/buzz (goes away when turn back to brightness max 100). Is this a defective monitor or do all LCDs do this?
3. Is it worth upgrading my video card to allow DVI connection (I assume this is how I would do it???) and buying a DVI cable to get higher res?
