I have 75” MI Q1, 75” Hisense U7K and a 65” TCL c755 delivering in a few hours.
The Mi Q1 developed a short in the panel a few months back after 3 years of purchase, but that’s just me luck I think. There is a bit of voltage fluctuation here so I would attribute it to that or the universe wanting payback for something IDK. I bought it for 1L mid 2021. Viewing angles are great, very bright peak hits beyond 1000nits and decently contrasts but it’s only FALD with limited dimming zones.
The U7K and c755 are miniled with much higher dimming zones. Both have 144hz panel, VRR and other HDMI 2.1 features. I use my U7K with sunshine and moonlight to stream games from PC to the shield pro with 1-3ms latency (lab or good wifi required). The u7k is great and very contrasty but even though its supposed to be IPS derived ADS panel, the viewing angles are terrible. The colors don’t shift but there is a lot of backlight bleed at >45 degrees. U7k has VA panels in 55 and 85 inch sizes.
The c755 (also called c805 in EU) is newer and has VA panels in all sizes I think and higher dimming zones.
Since you’re buying now I’d suggest skip the Q1. It’s cheaper because it’s a 3 year old model. I bought 75u7k for 95k at the introductory pricing when it was launched. U7k and c755 are both overpriced but atleast 10-20% I feel, but what can you do, at 65” and 75” comparable brightness and contrast levels with established brands like LG Samsung Sony are even more expensive.
My recommendation Oleds > c755 > u7k/u7n > Mi Q1
I don’t have a good perspective on U7N just yet, not been able to do my research.
Might sound privileged, but generally recommend everyone to either get Apple TV or shield or fire tv 4k/max or google chrome cast 4k. The inbuilt Os and hardware is just garbage in 95% of TVs resulting in terrible experience
