I'm now using three monitors with resolution capability of 1920x1080. The one monitor connected to Active Display Port is (from some reason) limited to 1440x900.

Is there a way to increase the resolution of the third monitor to have all three at 1920X1080?

My machine:

  • Graphics card - AMD 5770
  • Processor - Intel Core i7-2600
  • Ram - 8GB
  • OS - Windows 7 64bit.

VGC(Video Graphics Controller) driver is up to date.

Have you tried manual sensing of the displays and then forcing the resolution on the displays from the Catalyst control Panel?

It could also be that it won't allow you to use the display at full res until you combine it into an Ifinity Display. Which will make 3 monitors act as one.

is not the displayport who is making the problem but it's your screen resolution is limited to each one to 1440 x 900 if you want a better resolution you have to upgrade your screens to a better resolution like 1440 x 1080

Knowing that all three monitors work fine by themselves, it is probably an issue with the adapter. Either it has a limitation or it doesn't communicate properly with the monitor.
