Frequently Asked Questions
What is tone mapping clipping?
Clipping occurs when HDR brightness signals exceed what your display panel can physically emit, turning detailed highlights into pure flat white.
Why is 1080p sometimes crisper than 4K on my TV?
Native 1080p SDR feeds avoid tone mapping errors and motion interpolation scaling artifacts on mid-range televisions.
