Frequently Asked Questions
Why does TNT Sports Ultimate look dim and washed out on IPTV?
The channel broadcasts in HLG HDR; without Dynamic Tone Mapping enabled on your TV, HDR content appears dark and greyish.
How do I fix washed out HDR colors on OLED TVs?
Turn ON Dynamic Tone Mapping and set Color Gamut to Auto Detect in your TV's picture settings.
Is SDR better than HDR for live sports?
If your TV has low peak brightness (<500 nits), a high-bitrate 1080p SDR stream often looks brighter and more punchy than compressed HDR.
