U2515H, max resolution of 2048x1152 over HDMI?

My u2515h has a max resolution of 2048x1152 over HDMI

Has there been any update on this situation?

I am using a Gainward GTX460 GLH and NVidia 358.50 Drivers

I am using the supplied driver which shows a max resolution of 2560x1440 in the .inf file for HDMI

I have used two different HDMI cables which support 4K and both the Graphics card and monitor support v1.4

Why is it displaying a max of 2048x1152 and it also show recommended as been 1080p,1920x1080 in NVidia control panel.

RE: U2515H, max resolution of 2048x1152 over HDMI?

The only time 2048x1152 60Hz would be the maximum is when something in the HDMI chain is not HDMI 1.4. All four (monitor, cable, video card HDMI port, video card driver) must be HDMI 1.4 to get 2560x1440 60Hz. The monitor HDMI hardware is 1.4. So that leaves either the cable, the port on the video card, or the video card driver as the culprit. Or the port on the monitor is defective? Did you test both monitor HDMI ports? Some users with have created a custom resolution using a lower Hz setting of 50Hz to 59Hz to get 2560x1440.

The Graphics card is actually 1.4a which supports 2560x1440

HDMI cable supports 4K

Did you test both monitor HDMI in ports? Did you test the custom resolution option? You might also want to test older versions of the Nvidia driver to see if they also have the same issue.

RE: U2515H, max resolution of 2048x1152 over HDMI?

Yes I have checked both ports.  I have even gone to the bother of getting a hdmi 2.0 spec cable and have tried various nVidia drivers and nothing has automatically given the option to select 2560x1440 as a resolution.

I am starting to wander if there is an issue with the hdmi controller on the monitor.

Gainward GTX460GLH confirmed hdmi 1.4

Maby this monitor needs a firmware update?

What revision is this (A00, A01) ? We do not have any mechanism in place to allow customers to flash the firmware on this Dell monitor.

It is revision A02.

Also I was on to technical support earlier today but had to end the session early so outcome was not completed.

What exactly does holding the two outer buttons at the same time do? Is it some sort of monitor reset? as when I did this I just saw a plain grey screen for a few minutes, I was not told what it was doing!

The latest version I am aware of is A02. Using the picture below, explain what you mean by outer buttons?
