How to Enable 10bit Color Depth on Intel UHD Graphics 620

[Samirx]

Laptop Model: Dell Inspiron 14 5480
Display: Internal Dell Laptop Display
OS: Windows 10 Pro 64 bit
Processor: Intel Core i5 8265U
Graphics: Intel UHD Graphics 620

Recently I've reinstalled my Windows 10 on my Laptop. But from that time, I'm facing huge color problems on my Movies and Videos. The color of a movie that I played before reinstalling my Windows was very nice. But after reinstalling the Windows when I played the same movie then the color of that movie was so bad. I thought the problem is with my video player. Then I checked the Movie using other video players but the same color problem occurred. Then after checking all the Windows Settings, I find out that my Display Bit Depth reduced to 6 bit.

But before reinstalling the Windows, I'm 100% sure that my Display Bit Depth was in 10 bit. Now, I'm also sure the color of my Movies and Videos are looking so bad because of that 6 bit depth. So, now how I can switch back to 10 bit color depth?

Samirx, Thank you very much for providing that information and the SSU report.

According to the information shown in the SSU report, the graphics driver version currently installed on your computer is 27.20.100.8935. Also, the Windows version is 10.0.19043 Build 19043, which is the latest one for Windows* 10. Driver version 27.20.100.8935 is provided by HP, that is the proper driver for your system tested and validated by them and that contains the customizations done by Dell:

The Intel® graphics drivers are generic, meaning they might or might not work with your specific platform. Still, for testing purposes, we can try to install Intel® graphics driver version 30.0.100.9955, following the instructions in the link below:

This was appearantly one of the issues with an older driver: Intel support page 

I think that downloading the newer driver manually could fix this.

Sorry. Actually your solution didn't help me. I tried to install the Intel Graphics Driver 30.0.100.9955 by following your instruction using the both "exe" and "zip" file. But nothing changes. My Display bit depth is still 6-bit and because of frustration I didn't reply or check this thread anymore.
