Hi there

I have been trying to add a second monitor to my conceptD laptop, using an HDMI cable but I can't get it working. When I move the cursor over to the added screen the second screen goes blank, the cursor disappears for a while and then both screens refresh. Sometimes I get a blue screen error VIDEO_TDR_FAILURE, saying what failed: nvlddmkm.sys. I am running Windows 10 Pro Version 21H2, operating system build 19044.2251. The laptop is CN715-71P-79Y4. Can anyone advise me on how to fix the problem?

Thank you
