So my advice is to plow ahead with something the right size and has the VGA as well as HDMI connections.
The days of any 60, 75 or such Hz are over as the panel rates are fixed at 60. This is not an issue for most of us but if you are a 20 year old fighter pilot...
The 9200 in most machines will be ok so try to get by with just the new LCD.
I recently came into a decent tax return and I have around 300 - 400 $ to spend on a new computer monitor. My current one is an LG Flatron L1710S (as seen here: http://reviews.cnet.com/lcd-monitors/lg-flatron-l1710s/4507-3174_7-30524052.html?tag=mncolBtm;rnav ) and truth be told it is decent enough, the aspect ratio is a bit poor but I may just keep it as my second monitor. There was one very off thing that would happen in video games when looking at dark surfaces, the closest thing I can think of to describe it would be subtle wavy lines that looked like electric bolts sprawling all over the screen.
Anyway... my new place will have free cable, and I don't want to get 2 screens in such a tiny appartment, so I'd like one screen that does it all. My main focus has always been computers, so I am leaning towards a regular monitor. But... free cable, can't go wrong with that.
