HP EliteBook 820 G1 laptop and an 29" AOC Q2963pm display

I’ve got an HP EliteBook 820 G1 laptop and an 29" AOC Q2963pm display. I’d like to be able to run it at the maximum resolution of the AOC which is 2560 x 1080… do you have a product that will let me accomplish this?


Hi Max,

Thank you for posting the question here, and I am sorry that we could not get back to you sooner with the answer.

I’ve just quickly checked the specifications of the HP EliteBook 820 G1 laptop and an 29" AOC Q2963pm display. It seems both has the DisplayPort interface which should be able to support 2560 x 1080 screen resolution. I don’t think you’d need any additional products except the DisplayPort 1.2 or higher cable. (We are sorry but Plugable doesn’t sell any DisplayPort cable.)

If you have any reason that you’d need other way to connect the monitor to your system, please let us know. Plugable sells various types of USB graphics adapter that allow users to connect monitors through USB ports instead of using the video port of the system.

Hope this helps! Please let me know if you needed any additional information!

I’m using an HP DisplayPort to DVI SL Adapter (below) and I can only seem to get the resolution to 1920x1080. Are you saying if I went with a straight DisplayPort to DisplayPort cable it would work?


I don’t know about the details of the particular HP DP-to-DVI cable, but my guess is DVI limits the screen resolution.

We cannot guarantee about any products that not ours, but in theory, a native DP cable version 1.2 or above should be able to handle up to 3,840×2,160 screen resolution.

Hope this helps!

Let’s assume for a moment that it’s the graphics processor in the laptop that’s the limiting factor. If it was, do you have a product that would help?

Also, I did install the AOC monitor driver from here already since it’s anon-standard resolution but it didn’t help… it helped me get up to 1920x1080.


As far as I checked, the HP EliteBook 820 G1 laptop has integrated Intel HD 4400 graphics. The max resolution of the HD 4400 GPU via Display port is 3840 x 2160 @ 60 Hz. I don’t think the graphics processor of the laptop limited the screen resolution.


Please remember that you’d need to use a native DP to DP cable to get to very high resolution.

Regarding to the driver for the AOC monitor, I am sorry but we don’t know much about it. Please contact to AOC about the driver for the monitor, if it needed to be installed.
