I am a big fan of big monitors, but the market has not enough options. Here is "no compromises"
4K resolution
144Hz refresh rate
Nvidia G-Sync Compatible ready
DisplayHDR 1000 HDR standard
RGB on the back and bottom
VESA mount
2x 10W built-in speakers
and
43" size!
Price: unknown
Release date: "probably in first half 2020"
I call this the perfect monitor if you use your setup for both gaming and work. It's an ultimate beast.
