Hi, please how can I switch the 6bit depth to 8bit on the MSI PS63 Modern 8RC (Intel 620 Graphics) on the external monitor NEC PA272W? The older Acer Aspire V Nitro BE (Intel 530 Graphics) is working fine with the same USB-C to DP cable / monitor input.

Hi Adrian / Intel support team, thank you very much for your quick response. I did all the tests according to your instructions, the attached files are as follows: - W10_MSI_PS63_MODERN_8RC.zip: Windows 10 tests of MSI PS62 Modern 8RC notebook working only with the 6bit depth with the Nec PA272W monitor - W10_AspireVN792G.zip: Windows 10 tests of Older Acer Aspire V Nitro VN792G notebook, which works correctly with the same monitor and cable using the 8 bit color depth - LinuxMint19_MSI_PS63_MODERN_8RC.zip: Linux Mint 19 tests of MSI PS62 Modern 8RC notebook (Intel SSU, glxinfo, inxi) The monitor Nec PA272W is connected straight to the notebook MSI PS62 Modern 8RC (Graphics 620) via the USB-C to Display port cable (https://www.alza.sk/i-tec-usb-c-displayport-cable-adapter-4k60hz-d5483194.htm) and the color depth is only 6 bit, as already stated on the forums.intel.com site. Here I'd like to point out, that I tried to install various drivers on the MSI PS63 during the last 3 days - the newest igfx_win10_100.7463, then the older VGA_Intel_24.20.100.6286_W10x64_A, dch_win64_25.20.100.6577, dch_win64_25.20.100.6519, dch_win64_25.20.100.6471, dch_win64_25.20.100.6444, all of them without any success, I was not able to reach the 8 bit, so I went back to the driver version 24.20.100.6291 recommended for this notebook by MSI. Nevertheless, if I connect the same cable/monitor straight to the older Acer Aspire V Nitro VN792G (Graphics 530), everything is working fine, as can be seen here: I tried this in order to exclude the possibility of having a wrong cable / monitor input. (BTW, the older Acer notebook works also with the Aukey USB-C to DP dongle, however, this is not the case of the newer MSI) I thought, it can be helpful for you if I run the tests on the Acer Aspire V Nitro VN792G as well, maybe you can extract some information from the log files which may lead to the problem detection. In order to be helpful with the investigations, I went further on and I booted Linux Mint 19 OS from an USB-key on the MSI PS62 Modern 8RC (Graphics 620) and it seems to me, the display works correctly (8bit color depth) under Linux. Attached are the test files, hope, it helps as well. I also tried to connect the MSI PS63 MODERN 8RC to the PA272W monitor with a USB-C to HDMI cable. Albeit was the resolution correct (2560x1440), as well as the bit depth (8bit per channell), the refresh rate was only 30Hz. Please let me know, if you need some other help from me on this, as well as - once finished with the investigations - how to get rid of the 6bit color depth problem.

Hello OMedv1,

 

I would like to update the thread.

 

Can you please try to test the drivers 100.7463, 24.20.100.6286, 25.20.100.6577, 25.20.100.6519, 25.20.100.6471, 25.20.100.6444 on your Acer Aspire V Nitro VN792G?

 

This is because Intel® UHD 620 and Intel® HD 530 use the same drivers, so we would like to know if you can get 8-bit color depth with any of those drivers on your Acer Aspire V Nitro VN792G.

Hi Adrian,

 

thanx for the update.

 

I stopped the Windows update service, then I removed the Intel Graphics 530 device together with the the driver software. After the reboot, I installed the 100.7463 drivers and after the subsequent reboot, I did the tests (you asked for the last time) again, they are attached to the thread. The bit depth is still 8 bit on the Acer Aspire V Nitro VN792G with the new driver.

Hello OMedv1,

 

Thank you for the update.

 

The Acer Aspire V Nitro VN792G can get 8-bit color depth with the same driver 100.7463 that the MSI PS63 MODERN 8RC was tested so this means it's not a driver issue, the recommendation is to contact the system manufacturer because there could be a customization done by MSI* on their hardware that might not allow getting the 8-bit color depth on their system.

Hi AdrianM,

 

if the graphics were exactly the same on the Acer VN572G (Graphics 530) and the MSI PS63 (Graphics 620), your assumption would be quite correct. However, this does not seem to be. Using the same driver for two different devices does not necessarily mean, the hardware is identical. How can you explain, that by running the Linux Mint 19 on the MSI PS63 (Graphics 620) , the NEC PA 272W display gets the correct 8 bit depth, but by running the W10 on the same notebook, the display gets only 6 bit?

Hello OMedv1,

 

Thank you for your response.

 

I understand your point of view that you can get 8-bit color depth with Linux OS with the same computer however, Linux works on a different way than Windows 10 does so there might a be limitation by the system manufacturer on your computer that might not allow to use Windows 10 with 8-bit color depth also the official website of MSI* they only offer drivers for Windows 10 64bits for your MSI* PS63 MODERN 8RC so because of this we recommend you to check with them because they might limit some features of Windows OS to work with 8-bit color depth.

 

In case you need some assistance with Linux OS you can check the following link:

Hi Adrian,

 

to be honest, I'm not happy with your answer at all. If you carefully read my previous messages, you'd find out, I already tried to do the (re)installation of the MSI drivers, but it did not help at all. So being frank, your message is, that the grass is green, the sky is blue and I should not bother you, the Intel guys, with my problems.

 

Nevertheless, in order to exclude the false premises, I went to the computer store where the notebook was bought and I tested the MSI PS63 Modern with a Samsung 4k monitor, it worked pretty well at 4k / 60Hz / 8bit depth. This was just to exclude the hardware issues. I also googled some articles on this topic and found several similar issues:

 

https://answers.microsoft.com/en-us/windows/forum/all/bit-depth-color-depth-of-my-display-is-too-low...

https://forums.intel.com/s/question/0D50P0000490Tl9SAE/solved-intelr-hd-graphics-630-6bit-color-wind...

https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-Laptop-Thunderbolt-3-Dock-Dell-2717...

 

To sum up the topic, the things are as follows:

 

- NEC PA272W, Acer VN572G, W10 - 8bit (Acer recommended or the newest drivers): (OK)

- NEC PA272W, PS 63 Modern, Linux Mint 19.2 - 8bit: (OK)

- Samsung 4k monitor, PS 63 Modern, W10 - 8bit: (OK)

- NEC PA272W, PS 63 Modern, W10 - 6bit: (NOT OK)

 

There is no problem with the OS, as W10 can drive the PA272W with the 8bit on the Acer notebook. There is no problem in the MSI notebook / cable / monitor, as it is able to run at the correct resolution under the correct bit depth (either the PA272W or the Samsung 4k monitor). So I strongly suggest, the problem is in the Intel W10 drivers for the Graphics 620. Am I right, or wrong?

Hello OMedv1,

 

Thank you for your response.

 

You tested a Samsung 4k monitor with your MSI* PS 63 Modern laptop and you were able to get 8-bit color depth with it by using the same drivers that you used before on your NEC PA272W monitor with Windows 10, this means that it's not a driver issue because you can get 8-bit color depth with a different monitor. This could be a handshake issue with your NEC PA272W monitor and your MSI* PS 63 Modern laptop.

Hi Adrian M.,

 

if this is a handshake error, please explain, how is it possible, that in Linux, the monitor is working in the 8bit depth mode with the PA272W and in Windows it is not - under the same HW conditions? Is there no handshake necessary? And BTW, what is responsible for the handshake between the notebook/chip and the monitor? 😉

 

Is there somebody else than you, Adrian M., who can take over this case please?

 

BR,

Hello Ondrej,

 

I think this has been narrowed down to a compatibility issue between the Intel UHD Graphics 620's Windows 10 graphics driver and the NEC PA272W display. I cannot promise any fix is coming anytime soon since we cannot guarantee 100% compatibility with every single device that is available in the market. We'll check if we have immediate access to an NEC PA272W display for in-house debugging, but otherwise I doubt this will get proper traction with our driver debug team.

 

The only recommendation Intel can provide at this point is to keep your drivers up to date just in case a future update contains compatibility improvements.
