The 55-inch Mi QLED TV 4K has a 3840x2160-pixel (Ultra-HD) quantum-dot LED screen, with support for HDR up to the 12-bit Dolby Vision format. There s no full-array local dimming here, and the peak refresh rate is 60Hz even at 4K. There is also an auto low-latency mode with a claimed input lag of 5ms even at 4K 60Hz, giving the Mi QLED TV 4K some capabilities on paper when it comes to use with gaming consoles.
Sound output is rated at 30W through a six-driver, two-box system with four full-range drivers and two tweeters. There s 2GB of RAM, 32GB of internal storage for apps and app data, and a quad-core MediaTek MTK9611 SoC with integrated Mali G52 MP2 graphics. Although these specifications do sound impressive, I d have preferred more RAM even at the cost of less storage instead, since Android TV apps and app data don t tend to need that much space, but more RAM is always good in the long run.
