Cheers. Nice to see LG in there. I got two 4K 60Hz screens from them and they're quite decent. I paid for them the same amount these 144Hz screens cost nowadays (around £500 each)

I have the LG 27GN950-B and it's pretty good. On mine the factory color profile (downloadable from LG site) passes the eye test for color accuracy.

Tearing is minimal and I couldn't notice any lag compared to the previous 1080p 144hz TN panel. Granted it still has the RGB ring thingy but that's pretty easy to disable permanently.

If you get two it's the closest thing to a 7680 x 2160 screen you can get, bezels on the higher end LG product lines are the thinnest I've seen.

I've recommended this monitor on HN as well. I've had it for at least a couple years now with no issues. I love this monitor.

Worth noting, you need a very updated GPU, Nvidia 3000+, to get 144hz, otherwise it's 120hz. Not sure about the AMD story (but this monitor is G-Sync anyway)

Yes, your GPU needs to support the newest DisplayPort 1.4 standard (with updated DSC) for 4k@144Hz. AFAIK all Nvidia 20xx series cards and Radeon RX 6xxx cards support that. The fallback is 4k@120Hz which should work with older cards, but when testing with my GTX 1070 I had to add a custom resolution to get that set. With my new RX 6900 XT there are no problems.

LG GN950, new G7 28, G7 Neo, MU28 Gigabyte. None of them are good at HDR or color reproduction though.

For professional design work, nothing beats the XDR or studio display from apple but capped at 60hz.

Also, samsung and Gigabyte build is really cheap plastic. Display is fine for the price.
