Thanks,
I tried some HRD demos and they looks incredible.
I set all sources to Cinema night because Cinema day looks more aggressive for eyes and at night it's extremely bright. For first visitors I will switch to Cinema day
I set also Ultra smooth motion to off.
Anyway I see that I am extremely sensitive to motion probably due to childhood big gaming experience where it was always problem and correct graphic setting was needed.
High quality 60FPS videos looks great but in common low 1024p video (most probably 24FPS) I still see issues even from fast Flash disk.
The same also for some 4k YT videos. I haven't TV wired but measured 145 Mbps download speed in TV's location and YT recommendation for 4k is 20 Mbps.
To avoid interference my Router supports 5GHz and U7Q should support 5GHz too according to manual but in the TV WiFi settings I can't find if my network is connected to 2,4GHz or 5GHz and how to switch it.
I am not skilled in TV's but guess that conversion 24FPS on 60Hz panel will be always problem because "Ultra smooth motion off" will cause lags and "Ultra smooth motion on" will cause soap opera effect like blur. Am I correct?
Wish that I am wrong and motion can be adjusted by one of Ultra smooth motion settings: Off, Smooth, Standard, Clear, Film, Custom (Judder reduction 1-5, Blur reduction 1-5).
