Hi AndyWUA‌,

Could you explain a little bit better what the problem is? Are you referring to the LCD?.

On the pictures and in the games I see problems with the gradient. There are some circles and strange transitions of colors, hardly noticeable bands in pictures but they are. Especially in the sky, on a light gray background, black tints looks a bit green even in high resolution pictures.

Here is the better explanation of my problem (from another forum)

"I noticed a strong "color gradient" or "banding" issue where on images, some videos, and various colors within gaming looked almost like a paint by numbers photograph. The gradient/banding was so distracting that I knew something wasn't right. The display seems to be stuck in 16-bit color depth instead of 32-bit with a “color banding” effect. Here is a description of what I mean by that. If you are looking at a high resolution image of, say, a beautiful landscape with a big blue sky where the horizon is a very light blue at the bottom and the top of the sky is a very dark, deep blue. The transition from the light blue at the bottom of the image to the dark blue at the top of the image should be a very smooth transition. This laptop has a very visible color banding in the transition from light to dark blue. It should look like a high-quality picture in a magazine. What makes that transition smooth is the color depth. This laptop looks like it is stuck in 16-bit color depth. The thing is, Windows 10 doesn’t even support 16-bit color depth. I installed GTA 5 and noticed the same problem. Updating drivers did not fix the problem."

I don't know is it software problem or hardware. Not really happy to see such artifacts in games and even on my desktop wallpaper.

First make sure the Bios is up to date. Then, perform a clean install of the video driver, open the Nvidia Control Panel and try this:

Or you can also go to Change Resolution (also on the Nvidia control panel) > Color Depth: check what do you have and try by changing it.

Thanks for your kind reply. Unfortunately, I don't have deep color option. (Latest NVIDIA drivers from Dell) I heard about the way how to solve my problem by changing output color depth from 8 to 6, but I don't have such option (even with custom resolution and low freshrate). My video card is 1070, I didn't see any BIOS for 1070 only for 1080. I have QHD display 2560*1440 120Hz.
