DIAGNOSIS Incorrect picture settings for HDR content. The Select Series uses a basic HDR processor that needs manual tuning.
FIX While playing HDR content, press the Star (*) button on your remote. Go to Picture Settings. Set Picture Mode to "Bright HDR" or "Vivid HDR." Turn off "Auto Brightness" and "Content Refresh Rate." Set Backlight to 100.
IF THAT DIDN'T WORK The HDMI cable or port may not support the bandwidth. Ensure you're using a High-Speed HDMI cable (often labeled with "HDMI" on the cable). Plug into HDMI port 1 on the TV.
HEADS UP This model does not have high peak brightness or local dimming. HDR will always look dim compared to more expensive TVs. That's a hardware limitation.
