Questions and answers

Which TV is better for a bright living room?
Both are excellent as they both reach 3,000 nits of peak brightness and feature anti-glare coatings. However, the QM7K's CrystGlow HVA panel is specifically designed for ultra-wide viewing angles in large, bright spaces.
Is the QM7K worth the step up for gaming?
Yes, the QM7K includes Game Accelerator 288 and Motion Rate 480, providing smoother performance for competitive gaming compared to the standard 144Hz on the QM7L.
How does the sound quality compare?
The QM7K is the clear winner here, featuring audio engineered by Bang & Olufsen, whereas the QM7L uses a standard speaker configuration.
Do both TVs support the same HDR formats?
The QM7K explicitly supports Dolby Vision, HDR10+, HDR10, and HLG. The QM7L supports high-impact HDR but the QM7K is more versatile for various streaming formats.
