Can the RGB quantization range be add again

cheng__ — Wed, 25 Dec 2024 13:42:16 GMT

Can you add the RGB quantization range that was previously available in the intel control panel of the monitor? It seems that the default RGB output is limited (16-255), and I hope to output it completely (0-255), otherwise there will be color loss

Hello cheng__,

Thank you for posting on Intel Community Forum.

I perfectly understand that you're looking forward to the RGB quantization on Intel Graphics Software. I would just like to let you know that the Quantization Range is still available with the new software. Having said this, I would like to gather some information to address this correctly.

1. What is the make and model of your monitor?

2. Are you seeing the Quantization Range on IGS, if yes what are the available options?

3. Please attach a screenshot of what you are seeing on your end.

Additionally, to have a better understanding of your system configuration and components please generate System Support Utility (SSU) report. Please follow instructions here and send the report - How to get the Intel® System Support Utility Logs on Windows*

I'm looking forward to your response.

Best regards,

When I connected the monitor with a DP cable, there was no option for quantization range, while the HDMI cable had this option. I found an explanation in https://www.intel.com/content/www/us/en/support/articles/000058671/graphics.html. My monitor shows it has a limited quantization range when connected with a DP cable.It can display 4k 160Hz 10bit, but the A750 only supports HDMI 2.0. Nvidia or AMD graphics cards can adjust the range when connected with a DP cable, but Intel can't, that is a pity.

Hi cheng__,

It appears that you have located the appropriate article addressing your concern. According to the article, the Quantization Range option is only available if your computer's video output is native HDMI. I understand your perspective, particularly since you mentioned that AMD and NVIDIA graphics cards do not have this limitation. However, to fully utilize this feature, it is necessary to use a display with a native HDMI connection.

I hope this address your concern. Should you have other questions or concerns, please let me know.

Best regards,
