[Help] pg32uqx monitor randomly flashes HDR ON and briefly cuts screen view when HDR already on, mid game.

Windows 11, PG32UQX, 4090 graphics card connected through DP.

Have a second monitor connected by HDMI which doesn’t have an issue

It doesn’t happen with any sort of set frequency. The switching modes is something the monitor does when you change SD to HDR so it’s a monitor feature, but what I can’t work out is why it happens when everything is already setup and working in HDR mid game

Tried new cables. Tried disabling what I can in GForce. Looked for any system errors or logs. I can’t find anything or find a way to stop it

Anyone else have any ideas?
