Many LCDs can display at 800x600 with a native resolution of 1024x768 (or other numbers) and still look ok. There is no hard and fast rule on this so test the monitor you want at the resolution you want and see what happens.
It's usually acceptable.
What's also in your favor is a 15 inch LCD is really 15 inches whereas your 17 inch CRT display area is not 17 inches (measure it.)

I am in the market for an LCD monitor, but have read and experienced that unlike CRT's, LCD monitors only work optimally at one resolution. With my CRT, I find I need 1024 x 768 res. with large fonts in order to read many web sites and the text in some applications. So to get 1024 x 768, am I stuck with a 15" LCD or are there any 17" or larger that will give a good image with this low a resolution?
