"Download Custom Resolution Utility. Check at the bottom of the program for Extension blocks. Edit CTA-861 extension block AKA click on it and click edit. In the Data blocks you'll find a load of nifty stuff your monitor is capable of and there you will see dolby vision. Delete it and press OK. You'll need to do a restart after your done. You can revert back to the defaults if you want. It works a charm on my LG UHD tv. Stupid dolby. Thanx to Junglist724 for figuring it out."
