So looking at a range of 27" displays (I can't quite fit a 32!)
Given a i1D3 with a Pro2 spectro to use on the display are there quirks when profiling something like the QD-OLED screens because of the lack of polarisation and what seems like magenta bounce back?

WOLED won't do quite the same (RGB stripes) and the Tandem versions I think have two blues? But effectively the same stripes.

Are there caveats I should consider between the two technologies?

QD tends to be UHD right now, the WOLED tend to be 1440p, although I believe there are some new panels arriving that are UHD. But if WOLED just works better then as I'm mostly doing HD stuff maybe prioritise the colours over pixel sharpness.

The ProArt 27s look nice but they are 3 times the cost of QD versions. I'm not sure there's 3 times the benefit when I have a LUT box and can profile with ColourSpace.

Appreciate any thoughts from all those that know so much more than me!

Kinda down to you really.
For SDR any would be good...
But I probably would not want a 1440 monitor for 4K work.
If only doing HD then no real issue.
And a tandem WOLED is still a WOLED, but can do a bit better gamut - in blue as you say.

This ASUS will be available at the end of March 2026, and it will have direct ColourSpace integration with internal LUTs, etc.
