When I first bought a DLP Projector 20 years ago I plugged it in and the image drove me crazy. I could see the phase and I was so disappointed. I then realized the stereo was doing the same thing from the projector interference and eventually figured out it was a dirty power issue. This was my first foray into power conditioning and I bought a $200 Monster Power Center, which was big $$$ back then for me (yes I know branding and such, hadn’t found this site yet.) The image, colors, and sound never looked so good once it was in use and I had no more headache. If you are running your display on separate conditioned circuits change the refresh rate, you may also be seeing a discrepancy from the cable and the display’s rate. I suspect the display may not be synchronized with the output. You can force the two to be the same and that will give you the best results most of the time. Also I recommend turning down the brightness, they tend to be way too bright on the settings from the store.
While my Sundays are spent playing Audio all day. I love watching movies and shows at night. They both have a place, we are in the golden age of TV. There is a lot of great entertainment out there. Currently watching Altered Carbon on Netflix in HD with HDR. Awesome cinematography, plot, and I’m completely outdone that this level of quality is being produced in a subscription based service.
Good Luck!
