Intel UHD 770 with LG 35WN75C

[Smitty58]

Hello.

I have a new HP Elite Desktop 600 i7 with Intel UHD 770 graphics. I also have a curved LG 35WN75C-B monitor, connected via Displayport. When installing Windows 11, everything works fine until the moment the Intel graphics driver is installed. From this point on, the monitor remains black. The monitor has a resolution of 3,440 x 1,440 (QHD), which should support the graphics.

What can I do?

LG UltraWide 35WN75C-B

2 x HDMI 2.0 TMDS (18 Gbps)
1 x DisplayPort 1.4 HBR3 (32 Gbps)

3440 x 1440 @ 100 Hz RGB 10 bpc = 20.4 Gbps

Bandwidth over DisplayPort should theoretically not be the problem, but the HP computer only provides HBR2 protocol via on-board DisplayPort connector. Therefore, please check the settings of the monitor.

To view the OSD menu, press the joystick button at the bottom of the monitor and then enter the Settings.

Settings > General > DisplayPort Version > 1.2
