2nd display disconnecting and reconnecting constantly when turned off in windows

Yallendallis · April 8

Windows 10, 64 bit

The display is using a display port to HDMI cable, it's just an old IPS screen.

Basically, if I turn it off, or even disable it in the windows settings, it'll just come back seconds later, disconnect, and reconnect again.

My graphics card (2070 super) drivers are up to date. I'm out of ideas other than the cable, but I need to go from display port to HDMI to have the monitor in the first place, and I mean the cable doesn't seem defective, it's working correctly so long as I keep the screen connect and on. The display port end is in the GPU and the HDMI end is in the monitor.

Sounds like a bad cable or adapter to me. Try it in the native HDMI port on your GPU without the adapter, see if it still has the same issue. If it doesn't it's likely the adapter, if it does it's likely the cable.

Hmm yeah something strange is up, moving the cable into the first display port slot appears to have fixed it? I'm guessing that yeah the cable was bad or just loose (though I did unplug and plug it before) so if it reoccurs I'll probably just buy a new cable.
