I am using a 20" monitor with 1366x768 resolution for my old gaming laptop, and I cannot be more happy. Btw, the res of my laptop screen is 1920x1200, but good luck playing games on that native res. On 1366x768 however, I can play ALL existing games with no issues and with crystal quality image. Not to mention that all older movies are looking incredible good on that monitor. You need bigger resolution monitors, there are plenty out there. Or you just want them from free??
