什么时候能解决A770 的SDR 10bit输出的问题呢

[Allerstout]

现在虽然可以使用关闭hdr后的hdr显示器，配合windows11来实现，但是我这台显示器在开始10bit前后色温差异明显，而且还没办法修改。

我看到了一个英文的问题，并且读了一遍，那个问题已经经过一年了，开发部门还没有解决办法。

这应该是英特尔显卡开发部门的职责，他们宣称可以实现dp1.4以及hdmi2.0/2.1的功能，结果到现在却连单独输出sdr 10bit都做不到，已经涉嫌虚假宣传了。

我希望能有官方人员来明确地回答我的问题

Hello Allerstout,

After looking into this matter, we would like to let you know that the Intel® Graphics Command Center currently only supports changing the color depth for native HDMI outputs. The Intel® Arc™ Limited edition cards use a Protocol Converter (PCON) to drive its HDMI from the Display Port; thus HDMI is not native on these devices. If you have Intel Arc cards from other manufacturers and systems using mobile SKUs of Intel Arc, refer to the manufacturer's documentation to verify if HDMI is native to the card.

However, you can try the following as a workaround: If you are using an Intel® CPU with Integrated Graphics and your motherboard has a native HDMI port, connect the HDMI cable to the HDMI port on the motherboard instead of the one on the Arc GPU. Doing this will result in the Arc GPU handling the rendering of the game or other tasks you use your Arc GPU for, but the display output will be handled by the Integrated Graphics. This in turn results in the Color Depth, Quantization Range, and Color Format being modifiable in the Intel® Graphics Command Center.

Doing this does have the caveat that the display resolution and refresh rate will be limited by what is supported by the specific Integrated Graphics included in your Intel® CPU instead of what is supported by the Intel Arc Limited Edition Card.

Best regards,

你好，

很不巧的是我的cpu并没有集成显卡，而这正是问题所在，本该由arc gpu提供的功能却要让我们用户为此额外付费选择特定类型的cpu，这让我十分失望，这简直是英特尔的诡计。

这个解决方案我绝不认可，我需要的解决方案是不改动我硬件的同时来实现sdr 10bit输出，我认为这是一个软件问题。同时，我在其他问题的回答中看到你们说会开发这个本该存在的功能，这么久过去了，可我至今没有看到成效。

作为arc gpu的用户，我没有任何信心，我要求你们提供一个修复这个缺陷的时间。

Hello Allerstout,

We understand your frustration on this matter as you need to use the SDR 10-bit, and you are currently unable to use this feature. We understand that you are frustrated because you need to use the SDR 10-bit feature, but currently, you are unable to use it. We apologize for the inconvenience and would like to request some more time to resume our research on this matter. As soon as we have more information about this issue, we will get back to you.

Best regards,

Hello Allerstout,

We have consulted with the graphics team again regarding your concern. Unfortunately, there is no other solution available at this time. Please note that changing the color depth is only supported for Native HDMI connections, and the Arc A770 Limited Edition does not have Native HDMI. We appreciate your feedback and will pass it on to the appropriate team for consideration. Please let us know if you need anything else.

Best regards,
