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.

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

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.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
