Resolution Balance in a Dual screen setup

[#1]

I have 2 screens on my computer. 1 is a 28inch 1080p and the other is a 32inch 2k(qhd). so I am upgrading the 28" to a 32" and wanted to just get the same pannel to have identical processing for each monitor, think that this is better for my GFX card.

Am I really missing anything not having a 4k or 1:1 representation of my 4k projects in a dual-screen setup?
I deliver 4k about 30% of the time.
The 32" is calibrated and 10bit.

I have three screens on my desktop ... main UI is an LG Ultrawide 2560x1080; to left, Dell U2312HM 23" 1920x1080, both scaled at 100% in Windows. Third is above the LG, and is a BenQ PD2720U 32" UHD scaled to 200% in Windows. I primarily use the BenQ as a reference monitor, Transmit Out work.

But at times I've used it for Premiere's main UI because of running multiple things at once. It all works together quite well. And for the way the K count is going up I would suggest having one screen at least at UHD.

Yeah, you may have a point there. I just love my BenQ PD3200Q and there is a 300 dollar premium on 4k/UHD to stick with the same company. I have an LG 4k I normally output to see the final in a consumer format.

One last thing....
Is refresh rate a consideration? I am on a 60hz but not sure if having 90 or 100hz would be a positive?

Most colorists want their "reference" monitor set to refresh at the exact rate of the sequence framerate. Or double.

It gives you a bit cleaner look at the image. Other than that, probably doesn't matter.
