Time for LG to answer.

I have yet to see LG answer here so hit LG.com and call their support to see if they have a fix. If not, it's a new thing so pack and return as defective on arrival.

LG 34 UC79G-B

I did some searching..i think it has something to do with the panel..only supports 90% sRGB..it is only accurate at 60hz..increasing refresh rate its keep going like so
75Hz gamma 2.2 - 2.3
100Hz gamma 2.3 - 2.4
120Hz gamma 2.4 - 2.5
144hz is almost at 3.0...it's way too dark at that point..these tests are made with gtx 1080..but when i change gpu to rx 560 with freesync on..value of the gamma is better..not to much but they r better..

From a design standpoint

In reply to: LG 34 UC79G-B

That makes sense. However very few monitors get to 90% of the color spectrum. I see nothing wrong here except it gives the future designs something to shoot for.

https://www.notebookcheck.net/The-Best-Notebook-Displays-As-Reviewed-By-Notebookcheck.120541.0.html for example lets you sort by the sRGB column. There are not a lot of models that get better than 90%.

Yes there are better but I fear the price is going up so this is a balancing act of price vs all the things that make a perfect display.

I see this LG went for 700ish buck. Let me see if I can find what compares at CNET.

So yes, you can do better but I worry they percent drops as well on these.
https://www.cnet.com/products/samsung-cf791/review/ did list the sRGB numbers.
