Is anyone actually waiting for the new Pro Display XDR?
Here are a few but there are more. The point though is that so little content is compatible with 5k that most people are far better off with the limitless options at 4k, any hz you want, HDR, so many advantages. https://www.walmart.com/ip/5539460685?sid=8dd55d6b-af36-4fcf-b75e-753418105280 https://w

Best monitors for programming to buy right now in YOUR opinion?
I like the 5k2k 40” monitors. I have both the lg 40u990a that does 120hz and an older hp z40c g3 that are sometimes available as cheap refurbs on eBay. One for work, one for home.

[User-Trial] Perfecting the Pro Desk: Field-Test the New LG UltraGear evo GM9 (5K, 218 PPI) – Testers Wanted!
Oh this would be so cool to try! Some background. I’m an iOS engineer with a photography hobby. My primary setup for years was a 32” 4K monitor with a MacBook display below it and an iPad to the right of the 4k monitor via sidecar. My desk is nearly 100% productivity, but someday soon I’ll finish Ba
