I just bought a 43 inch 4K 5 series tv. I’ve had it about 4 days and when I put on 4K movies from Disney+ or anywhere else the picture is snowy. Regular hd tv works fine. Any know what is causing this?
Please provide some additional detail. I am assuming this is a TCL Roku TV. Please confirm the model number.
I have watched D+ recently and have no issues with 4K. Could you be a little more descriptive about what you are seeing? A "snowy" picture on a TV brings an image of a weak signal from OTA analog TV. Since all TV is now digital, I can't understand what you are seeing. Are you seeing pixel blocks, odd colors, or something else? HDR not displaying correctly is usually just a dull image that lacks any "snap".

This LG TV does not handle HDR properly. The images are way too dark and no settings tweaking makes them acceptable.
This problem is apparent on Prime Video via HDMI as well as on the Prime Video app installed on the LG OS. My specific test video is the Amazon-produced Chi-Raq by Spike Lee. I used a DVD of the same content on my upscaling Sony BD player as a control and the DVD disc displayed properly and far better than the 4K HDR streaming on this TV.
ROKU reports that the LG TV HDMI port is 4K, HDR, 60 Hz, HDCP 2.2 via the auto-detect in ROKU/Settings/Display_Type.
My solution is to choose the 4K, 60 Hz setting without HDR. Now 4K videos that were detected by the TV as having HDR play properly. The LG TV has HDR-effect display settings for non-HDR items to compensate.
This LG-TV HDR issue does not appear to be exclusive to the ROKU Stick+ but ROKU's settings flexibility provided the work around that was needed for this TV.
