Dell U2410 Resolution Issue with DisplayPort: Max resolution NOT available/not possib

[DualMonitors]

Hi All:

I have been using the Dell U2410 monitor via its DVI-D port for around 6 months. It has worked without issues.

I just built a new PC and started using the U2410 in a dual monitors configuration (along with a U3011) with TWO DisplayPort cables from my new video card. The U3011 has worked without issues thus far. The U2410, however, would not display its highest resolution. Only resolutions below 1920 x 1200 are available!! Furthermore, it was only able to be at 24Hz!

I did a great deal of troubleshooting before writing this. I swapped DisplayPort cables: both cables proved to be fine. I tried BOTH ports from the video card: both ports work fine with the 30" U3011. The ONLY item (the only possibility) is that the DisplayPort of the U2410 is defective!

Reconnecting the U2410 via the DVI-D cable works again. Hence, it is only the DisplayPort input that is seemingly the broken part.

May I ask if this is a common issue with the U2410? What might be the best resolution of this problem?

Thank you all in advance.

I assume that you have a Radeon based card?

I haven't tried it myself but I know that one of the DVI ports are single link only and doesn't support resolution over 1080p on the other hand you are using strictly DisplayPort.

I have 3x U2711 setup and I had hell of a time trying to figure out why it wouldn't work but in the end it was because I didn't have Active DisplayPort adapters. Make sure that they are dual link as well since single link only supports up to 1080p
