Resolution issue with intel UHD Graphics 770

[Technado]

I have a Dell OptiPlex Micro 7010 that is having resolution issues, it won't display ultrawide resolutions only shows up to 1080p but if I uninstall the intel driver and go back to Microsoft basic display driver the resolution is there and usable, have tried a complete re install of windows, the latest intel and dell display drivers no change, have all the latest firmware updates for pc and screen. The screen in question is a LG 29WQ500-B and screen is connected via hdmi, have also tried different hdmi cables with no luck.

Apparently Dell has decided not to offer a higher resolution via the integrated HDMI port.

So this is a limitation on Dell's part, even if it still works with the Microsoft Basic Display Adapter driver.

You should connect LG 29WQ500-B via DisplayPort for 2560 x 1080.

Well, ive only got two displayports. Dell 7000 Micro.

I forgot to add, I have tried a display port to hdmi converter that apparently had the ability to output up to 4k, as the monitor only has hdmi input but no change

[MUC]

Could you specify the converter and provide a link to where you purchased?

[Technado]

It didn't solve the issue so would be no point buying one

[MUC]

However, it might help to understand the problem if you tell us which adapter exactly you tried.

Hello Technado,

Thank you so much for posting in our Intel communities.

We understand that you are unable to get a higher screen resolution when using the Dell OptiPlex Micro 7010.

According to the specification of the OptiPlex Micro Form Factor 7010 (Page 21), HDMI 1.4b supports 1920 x 1200 at 60 Hz, while DisplayPort 1.4a supports 4096 x 2304 at 60 Hz.

Therefore, you can use the DP port of the computer if you want to use a higher screen resolution.

Furthermore, we recommend that you please contact DELL technical support (1-800-88-0022) to verify the supported resolution of the computer.

In addition, please refer to the following links for additional troubleshooting steps and follow the instructions provided there:

• Unable to Select the Native Resolution and Other Supported Refresh Rate of an External Display Connected to Intel® Graphics.
• How to Set Custom Resolutions and Modes in the Intel® Graphics Command Centre

Thank you, and have a great day!

This adapter is described by the manufacturer as suitable for up to 3840 x 2160 @ 30 Hz. This corresponds to a bandwidth of 9 Gbps. Theoretically, this is easily enough for the requirements of the LG 29WQ500-B monitor.

It may be that this adapter leads to limitations due to the way it works (DP++ Level Shifter > HDMI 1.4 300 MHz TMDS). Please try the remedies suggested by @ACarmona_Intel.

To transfer the OptiPlex Micro 7010's HBR2 output to HDMI, there are other converter cable solutions available that you can try. These contain a chip that actively converts the transmission protocol, for example:

CAC-1082

or

CAC-1087

This would be sale or return if it doesn't work.
