SFF N100 can't output via DP port

[Dis93]

I just got a Windows 11 Pro N100 mini pc. I can connect it to a HD TV via hdmi and get a signal. I cannot get output from the DP. I have a DP to HDMI cable to my monitor.

If I only have that connected, in device manager I get a display listed with a resolution of 640x480 only.

If I have both connected I only get the TV/Monitor active.

I can use the HDMI to HDMI to the monitor, so the monitor is fine.

I have tried 2 different DP to HDMI cables, one that worked on old PC, the other a brand new DP 1.4 to HDMI cable.

Windows cannot detect a 2nd monitor.

Any advice appreciated.

Hi Dis93,

Thank you for posting in Intel Communities.

To assist you more effectively with the issue you're experiencing, could you please share the manufacturer of your SFF N100? Additionally, if possible, provide a link to the specifications of your unit, which will allow us to review the details thoroughly.

Furthermore, we would appreciate it if you could inform us of the model of your graphics card and the current driver version you are using. This information is crucial for us to understand the situation better and offer a precise solution.

Lastly, does your monitor have a DisplayPort (DP) input? If so, have you tried connecting via a DP to DP cable? This could potentially resolve any display issues you might be facing.

Your cooperation is greatly valued, and we look forward to your response so we can proceed with the necessary troubleshooting steps.

Best regards,

It's a Dunhoo N100.

The specs are shown in the uploaded images.

It has integrated UHD 800 graphics according to the product page.

My monitor does not have DP input.

I have tried installing the updated grpahics drivers, version 31.0.101.4952

I have had good experiences with this active protocol converter cable. It is not the cheapest, but it is good:

Club 3D CAC-1087

I got a USB-C to HDMI convertor. That works fine.

Attached is the SSU report.

I don't have a monitor with DP input.

I haven't reached out to the seller, as it was a fulfilled by Amazon purchase.

I haven't reached out to the manufacturer as I can't find a website for them.

Hi Carmona A.

I tried the suggestions as indicated with no success.

I have given up on the DP connection as the USB-C adapter is working.

Thank you for the assistance.
