I have the Xbox one x hooked up through my Sony sound bar using arc3 HDMI with high speed audioquest cinnamon cabling to my Sony x900f tv. I seem to have random black outs that act almost as if HDMI lost signal and reappears within few seconds at random. I also have small tiny white flashing dots almost looks like tiny static white specs all over my screen at times and the only way to fix it is to unplug and plug in the TV power cord. I've tried everything I can think of and cannot seem to figure out why it's doing this. Of course, I didn't get geek squad protection and I'm past the return point but the tv is still under manufacturer warranty until October. Don't know what to do either as this issue appears to be sporadic but annoying to have to unplug and reconnect my tv often for a brand new tv. Any ideas?
