Which is better for a bright living room?

The Hisense U8. Its Mini-LED backlight reaches up to 5,000 nits and has an anti-glare coating, while OLED loses punch in daylight.

Which has better picture quality in a dark room?

The Roku Pro Series OLED. Self-lit pixels give true blacks and no blooming, which the Hisense's local dimming cannot match.

Which is better for gaming?

The Hisense U8. It runs at 165Hz, takes 4K 165Hz over USB-C, and has three HDMI ports versus the Roku's 120Hz and two.

Is the Roku worth the extra $34?

Only if you watch in a dark room and value Roku OS. At $849.99 versus $815.99 for the 75-inch Hisense, the Roku buys contrast and simplicity, not brightness or ports.

Neither has a published lifespan edge. OLED can develop image retention from static logos or tickers; Mini-LED has no burn-in risk but dimming zones can degrade unevenly over many years.

Do both support Dolby Vision?

The Hisense lists Dolby Vision IQ and HDR10+ Adaptive. Roku Pro Series sets support Dolby Vision but not HDR10+, so HDR10+ discs fall back to HDR10 on the Roku.
