Hi. I recently acquired a Dell P2217H. It has a maximum resolution of 1920x1080@60hz and 3 inputs: VGA, HDMI and DisplayPort.
Over HDMI, it works just fine at 1920x1080 as advertised.
However, over VGA and DP it only display available resolutions up to 1680x1050. To make it work at 1920x1080, I have to add a custom resolution using CRU (or through Nvidia control panel) on Windows.
With the little bit of knowledge I have, I decided to check the monitor's EDID. The problem is that the 1920x1080 resolution is defined in an extension block, and apparently my GPU cannot read the extension block through DP, only using HDMI. I was certain that this was a monitor issue until I read, in the CRU thread, that Nvidia driver has issues with extension blocks. And I only tested the monitor in 2 computers: My desktop (ASUS 1070 GTX) and my laptop (onboard Intel with a GeForce 840M, and I believe the VGA port is connected to the GeForce GPU).
My question is: Is this likely a monitor issue and I should try to have Dell get me a working monitor, or this could just be the Nvidia issue? And why does it work through HDMI but not DP or VGA?
Here's the output of edid-decode of the dump I made through HDMI
Thanks in advance![Smile]( "Smile")
PS: Your nvidia driver patches and CRU saved me many times, thanks a lot for your time and effort.
