Hello:
My ThinkPad X395 shows a color depth of 6 bits. Is it normal to be so low? I use the touch panel with FullHD resolution.
Drivers are updated:
Radeon Vega 10 26.20
Screen 6.13.3.0
Hi
Welcome to Lenovo Community Forums.
Color depth can range from 1 bit (black-and-white) to 32 bits (over 16.7 million colors). Kindly share to us a screenshot where you the 6-bit color depth of your ThinkPad X395.
You may follow the steps below to check the screen depth of your machine:
Click on Control Panel > Appearance > Personalization, clicking Adjust screen resolution.
Click Advanced settings > Monitor tab > Colors, select True Color.

Hello,
I do not have a ThinkPad X395 myself, but my understanding is that a 6-bit display panel means that the screen displays 26 × 26 × 26 bits for red, green and blue colors (or 64 × 64 × 64), which comes out to 262,144 colors in total. However, the screen controller dithers these to generate lighter and darker versions of each color. This approach gives an effective display of 28 × 28 × 28 colors (or 256 × 256 × 256) which gives the 16,777,216 colors after dithering. The benefit of the 6-bit panel is that it is slightly faster than an 8-bit panel, as it only has 75% of the bits to switch between (compared to an 8-bit panel, that is). At least in theory. From a practical perspective, the difference in performance is probably less unless you are doing something on the screen involving lots of moving graphics like a video game.
At least, that is my understanding of how it all works; I typically do not work with display panels, but I am certain if I have gotten anything wrong, one of the experts on the technology will correct me.

Hello
I also have the same problem in an IdeaPad S145-15IIL, consult Intel and they told me that it is a problem of the video driver, that I should notify Lenovo because they should include the correction in a future update of the controller, I contacted the Lenovo support and downplayed the problem ... I see that I am not the only one, the problem is seen when the driver is uninstalled and the generic microsoft adapter remains, where if the 8 bits are shown in depth, it significantly increases the quality of the color, but obviously the performance decreases ...
