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. I prefer one large screen over multi screen setups and must have usb hub built in so I can have a single thunderbolt cab

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

Monitor for MacStudio and PS5

LG 40U990A-W ultra wide and BenQ RD280UG in portrait. The LG is one of the few Thunderbolt 5 monitors meaning it'll act as a hub for your devices and even ethernet and daisy chaining for more screens. Avoid OLED due to burn in risk with computers

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.

Customize your UltraGear experience with LG Switch

u/LG_UserHub Is the personalized picture wizard available for 40U990A-W ? I don't see the option in the LG Switch app and I'm struggling with insufficient brightness which so far seems to be only partially resolved by using the vivid mode which I don't like because it distorts the colors. Thanks

MacOS 26.1 does not display over Thunderbolt on LG Ultrawide displays. Partial Temp fix implemented.

My work Macbook Pro M2 Pro on macOS 26.3.1 refuses to detect/connect to my new LG 40U990A-W Thunderbolt 5 monitor no matter what I do. The display itself is on the newest firmware, the only quirk I've noticed is that I cannot go to DP 1.2 - only DP 2.1 or DP 1.4. I understand that the M2 Pro does no
