Just to clarify things a bit:
17 and 19 inch LCD's are NEVER EVER 4:3! They are either widescreen or 5:4 1280x1024.
If you want 4:3 LCD's with good viewing angles, there are 20 inch MVA and IPS 1600x1200 panels, and 21.3 inch 1600x1200 IPS and PVA panels. The HP LP2065 is still on sale and a remarkable 4:3 display: IPS, great angles, very fast, no noticable iput lag. If the 19 inch panels are PVA, you probably have lots of LAG. The mentioned Acer above is a TN screen, so not really great for vertical games.
