HDMI works then it doesn't

I have a BenQ projector hooked up to my laptop via HDMI. It works fine at first, but randomly drops signal after 10-15 minutes. Tried swapping cables and ports, same issue. Could it be a handshake problem or overheating? Any ideas?

hi @juliandalt have you tried to adjust the HDMI Equalizer? BenQ projectors usually have an HDMI Equalizer setting in the OSD menu to boost signal strength. Changing this from Auto to a fixed value can stabilize the connection
