Monitors Highest refresh rate 27" 2K/QHD monitor under 20K

I have the acer one and is pretty good. It was below 19k in sale and even lower around 18k during sale.
 
I had considered the M27q at some point in the past, but dropped it after I saw a few reports of people complaining about the pixels being set in BGR and not RGB. Apparently this makes text difficult to read.

If your intention is mostly to game, it's a fine monitor, but maybe not a good one for prolonged work related tasks.
