And I use a 55" 4K TV as my "monitor", because sub-$1,000 >>30" monitors with internal 3D LUT-based color calibration aren't a thing.

And, while I don't use the speakers, the TV's S/PDIF output is nevertheless handy for routing the audio output of whichever of the four HDMI inputs is active to the single S/PDIF input on my audio interface.

Finally, the TV has an RS-232 port that allows control of essentially all of the basic "TV" functionality, which was handy for setting up keyboard shortcuts for input switching, power, and brightness control; IME, monitor controls for such things that don't involve diddling with buttons on the side of the device itself are few and far between.

What is said TV response time? If it's bigger than 2 ms then that's a no go for me.

Because you have a 500hz HDMI output? Yeah right.
