Intel UHD Graphics 630 doesn't recognize a Panasonic projector

[kilpikonnavoimaa]

Hello!

I'm having trouble connecting my Panasonic PT-AE3000E projector to my HP ProDesk 600 G4 SFF, which has Intel UHD Graphics 630. I'm using a displayport-HDMI-adapter and an HDMI cable.

The HP doesn't recognize the projector at all. I've tried all three of the hdmi-ports the projector has and both displayports on the pc. The pc does recognize other screens through both displayports and other monitors work properly with it.

My old laptop recognizes the projector and connets without a problem (using an HDMI cable with a minidp-HDMI-adapter at the laptop-end) and the projector works fine with that older machine.

The UHD Graphics has 31.0.101.2111 driver, dated 19.7.2022 which seems to be the newest one.

What should I do? Roll back drivers?

I think it all depends on the adapter you are using. Do you have a link to the product?

Unfortunately, the information on your current adapter is not clear. I think you will achieve the best compatibility if you use a DP++ adapter from HP.

According to the manufacturer, the DisplayPort connectors on the HP ProDesk 600 G4 SFF support DP++, also known as "Dual-Mode". This means that when a DP++ to HDMI adapter is connected, the computer sends HDMI signals instead of DisplayPort signals on an electrical level.

Please search online shops in your country for the part number F3W43AA. This adapter from HP should also be available in the HP online shop. It is very cheap.
