X1 Carbon 7th gen display 6 bit depth

2019-08-26, 15:59 PM

Hi Guys, I've been seeing some issues with gradients on my X1 Carbon 7th gen with the 1920 * 1080 touch screen. Upon closer inspection, I saw in the windows settings menu this tid bit of information, for which I have no explanation.

 

All the drivers are up to date both on the display as well as the graphics card, both drivers being from august. I've looked in all of the windows settings as well as intel's and found 0 configurations which could apply to this problem. I can try to add some pictures of the screen gradient from things like Netflix to showcase how bad it looks.

 

Any ideas?

This was/is a driver issue with the Dell u2717d, and perhaps others. For me it's been resolved by a recent driver update, see this thread, and an earlier solution was to downgrade the driver, see here. Maybe try running Lenovo Vantage and see if there are any updates that Windows Update didn't offer.

Thanks for the helpful links. I had stumbled upon them myself, but with no real luck in fixing it for now. I can understand issues with external monitors, but this is monitor the laptop came with.

To be honest I'm a bit dissapointed that such situations can happen with such a high end device, where I have to go debugging something so intrinsic as the laptop's monitor

Oh oops, if it's the laptop screen itself then I agree it shouldn't happen. Did you run Lenovo Vantage? It's a Windows Store App that may offer different/newer driver updates than Windows Update. See this link

My screen shows up as 6 bit also. I found a test online and confirmed this is only a 6 bit + FRC monitor. That is disappointing for what is supposed to be a high end machine.

I have yet to see any 14 inch Full HD screen with on-cell touchscreen with 8-bit or higher color depth. My ThinkPad 25's touchscreen is also 6-bit. X1 Yoga's screen is a different story because it is not using "on-cell" touchscreen; it is using a separate digitizer from Wacom. Therefore, I think this is by-design, and I guess that Lenovo can't find a better touchscreen panel to use.
