How to customize screen resolution in windows7 with ATI graphics card

By | 2013 年 12 月 12 日

Recently, I brought a Dell U2713HM display, with resolution of 2560 * 1440. And my current computer have a HD6800 ATI card.

Then when I connect display with DVI cable, it turns out that the highest resolution I can set is 1920 * 1200 in the windows settings. That’s sucks.

So after tried a lot of solutions, there is one works!


first, unlock the pixel clock of grahpics card, using:

atikmdag-patcher-1.2

second, specify your custom resolution using CRU:
