I have my Bolt Vox 3gb connected directly to my TCL 65R617 via the TiVo supplied HDMI cable. I have two issues - whenever the Bolt changes resolution (for instance Cable to Netflix) I get the HDMI snow screen. I've switched out the HDMI cable, same result. My solution was going to be locking it in on 4k but when I do this there's a noticeable dip in color saturation. The current workaround has been to lock in at 1080p which is fine for Cable TV, but I'd like to take advantage of 4k streaming from apps like Netflix and Amazon Prime. Has anyone else experienced this color saturation issue when using the 4k setting? Thanks.
