Unless you use a CRT, i'd recommend to get a 1366x768 monitor with a VA panel. The low DPI makes pixels look crisp, if you game you'll get great performance even with low end hardware while you'll be able to play a lot of older games in a natively supported resolution (1024x768, centered) without UI issues and (the reason for VA) you get deep blacks (not as deep as OLED but certainly better than the washed out garbage you get with IPS panels) which are great on both movies and games. The main negative of VA is low refresh, but unless you are playing competitive games you should be fine.
If you use a CRT, then carry on. Although note that those guns wont live forever and they do wear out. I use mine only on the occasion i want to play some old 2D game that simply doesn't work with anything other than its "native" resolution.
