Last year, I bought a laptop ( yoga14s 2021) from lenovo who asserted their product's panel support 10-bit color depth.
Indeed, on the same product with AMD integrated graphics can correctly open 10-bit output.
But lenovo offically asserted that the Intel version laptop could not support 10-bit output until Intel solves the driver issue.
Almost one year passed by, is there any progress?
Is it ture that the problem is caused by Intel driver issue?
Thank you for posting on the Intel® communities.
In the case of a laptop, you need to take into account that the drivers that your laptop need in order to work as advertised is provided by the original equipment manufacturer of it which in this case is Lenovo, what they do is that they take our generic drivers, and customized them, so they can work with the laptop before even releasing the product; however if a problem is presented and they are working with us to fix it, you should report this issue internally with them so they request any pertinent information and logs so they can continue working with us internally; with this said, please bear in mind that our generic drivers are not supposed to fix customization issues since as their name suggests they don’t have any special customization for any specific platform related issues such as an integrated flat panel limitation.
Besides that, take into consideration that Intel graphics does support 10-bit and 12-bit color depths (known as deep color). On our current driver implementation, the color depth will be set as per the OS configuration. Normally, you should be able to enable HDR (High Dynamic Range) and WCC (wide color gamut) which would configure the Operating System for higher color depths by going to Windows > Display settings > Windows HD Color. If the content you're trying to view is 10-bit, you should be able to see it by switching to Full-Screen mode, and the driver will automatically switch to said color depth so long as HDR and WCC are enabled. This is also true for most DirectX applications.
