MSI glossy 5K miniLED MPG 271KRAW16: Monitor of my dreams?

I have seen no official confirmation, some news aggregator websites like that one mention it as a given with no source. Others mention DP2.1 DSC (like displayspecifications.com) which is meaningless - of course it supports DSC, it's part of the standard - and points towards not enough bandwith to dr

My Take on the LG UltraFine 40" 5K2K Nano IPS Monitor (40U990A-W) – Steer Clear

Just do what I said: connect all your peripherals, mouse and keyboard to 40u990a. Then for your first computer that using hdmi, you connect both hdmi AND usb-c(the one at the lower -right side in the back, with a “out” label) to it; the second computer should just connect byThunderbolt(not the daisy

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

I've been searching for months, but can't find a monitor. It seems nothing has advanced in the 7 years since I bought my last screen, for those of us who don't want an OLED. It's all just 1440p garbage.

That's the first one on my list, the LG 40U990A-W. It's the LG panel, packaged and sold by dell. Thing is, it also carries a $400 price premium over just buying it from LG.

LG 5k2k pricing

If you like sharp readable text then it's a bit too big. The PPI (pixels per inch, pixel density) is 125 PPI vs the new 39inch which is 142 PPI. And just for comparison my 5k x 2k LCD (lg-40u990a-w) is 139 PPI. A 32-inch 4K monitor typically has a pixel density of approximately 138 PPI (pixels per i
