Hello Akrkhan71,

Thank you for posting in Intel Communities.

To get a better understanding of the issue and be able to provide an effective recommendation, please provide the missing key information here:

1) Is this a first-time setup and having an out-of-the-box issue?

2) Can you confirm that this is the exact monitor that you have (54.6 Cm Fhd Monitor With LPS Panel Ls22D300Gaw | Samsung India)?

3) How is the monitor connected to the Intel® Arc™ A580 Graphics (thru HDMI or DP)?

4) Are you using direct cable (e.g. HDMI to HDMI or DP to DP) or using a converter/adapter?

Additionally, I highly appreciate you sharing your system configuration so I can fully check and provide you with an accurate fix. This could be possible by downloading the Intel® System Support Utility for Windows* software. When the download is complete, launch SSU.exe.

Scan: Check the box Everything.
Click Scan.
Review: When finished scanning, click Next.
Click Save. *Attach the SSU log file as you reply.

I look forward to your response.

Best regards,

JeanetteC.

Hello is there any update?

Please check the driver settings for the color depth output. "BPC_8" is sufficient for this monitor. The panel can't display more than that anyway. The unavailability of 100 Hz may be due to the driver's calculation that 10-bit @ 100 Hz is not possible because of bandwidth limitations over HDMI 1.4 protocol which this monitor is limited to.

How Do I Set Color Depth or Color Format in the Intel Graphics Command Center?

If you are using Intel Graphics Software, you can find the setting here:
