Intel Iris Xe Graphics does not let me to change 1920x1080

[BillyClassTime]

Hello,

I am experiencing an issue with my setup, and I hope someone here can help me troubleshoot. Here is the scenario:

Scenario:

I have two laptops connected to an ATEM Mini switcher. The first is an HP laptop with a 10th Gen Intel Core i7 processor, 16 GB of RAM, and Intel Iris Plus Graphics. The second is an ASUS Vivobook with a 13th Gen Intel Core i7 processor, 32 GB of RAM, and both Intel Iris Xe Graphics and an NVIDIA RTX 4060 GPU.

Both laptops are connected to splitters that send the signal to both external monitors and to the ATEM Mini for switching. The HP laptop works fine with this setup, and I can get the full 1920x1080 resolution on both the monitor and the ATEM Mini without any issue. However, I’m encountering a problem with the ASUS Vivobook.

Problem:

When I connect the ASUS Vivobook through the splitters, the maximum resolution displayed on both the ATEM Mini and the monitor is 1280x720, and I am unable to change it (the option is greyed out). However, when I connect the monitor directly to the ASUS Vivobook without using the splitter and without sending the signal to the ATEM Mini, the resolution correctly goes up to 1920x1080, and I can change it without any issue.

This problem does not occur with the HP laptop: the splitters work fine with it, allowing the maximum resolution of 1920x1080 without any problems. Even when I use the HP splitters on the ASUS, the resolution is still limited to 1280x720 and cannot be changed.

I have also tried changing the splitters to ensure they are working correctly. When I swapped the splitter from the ASUS Vivobook to the HP laptop, the resolution works fine on the HP (1920x1080), but the issue persists on the ASUS Vivobook with the resolution still limited to 1280x720.

The ASUS Vivobook is much newer and more modern compared to the HP (about 4 years difference), yet the resolution issue persists with the ASUS when using the splitters.

Please, anyone can help me resolve this issue? I would greatly appreciate any suggestions or guidance on how to fix this.

Hello BillyClassTime,

Thank you for posting in Intel Communities.

 I would like to know more about your system and display configuration details to fully understand where the issue truly lies. Please help share the missing key information below:

1) Make/model and specifications link of the monitors used on both systems.

2) Please share the display configuration setup that you have. A short video clip or a clear photo showing the highly appreciated.

3) Is this a first-time setup getting this issue or has this configuration previously worked?

4) Please confirm if this the ATEM Mini you were referring to.

5) Kindly share your system configuration (for both laptops) so I we 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 (.txt). *Attach the SSU log file as you reply.

I will wait for your reply.

Best regards,

JeanetteC.

ATEM Mini is a small live production switcher from Blackmagic Design for online broadcasts. It receives HDMI video signals and processes them.

Setting up video connections is always a give and take. The display (or sink) devices tell the source devices what they can do and then the source devices establish a connection. Intermediate devices affect this behavior.

To understand the situation, please provide the information that @JeanetteC_Intel requested: Make and model of each hardware component involved: laptops, splitters, monitors. And cables ! Feel free to add links to the products.

Please describe the arrangement of the hardware (incl. cables) in more detail:

Laptop > cable X > splitter > cable Y > ATEM Mini? What is the splitter (make and model) for? Is there a monitor attached to it? Which one? Feel free to provide a small sketch.

Please generate a Report for Intel Graphics Drivers for both situations (working / not working) and attach the output files here.

Hi!

Sorry for the late response, the email was junk folder directly and now I saw it! 

Laptops:
1) HP and Asus VivoBook attached SSU Outputs files.  (Attached to this email)

2) Yes this is the ATEM Mini (The basic producto of blackMagic) just of the link Blackmagic Design ATEM Mini Pro – Thomann España

Blackmagic Design ATEM Mini Pro – Thomann España Cualquier dispositivo con una salida HDMI (ya sea una cámara digital, un ordenador, un dispositivo inteligente, una consola de videojuegos o un reproductor de DVD/Blu-Ray) se puede conectar al ATEM Mini Pro sin dificultad, y su facilidad de uso es ejemplar. www.thomann.de

3) The splitters: Ewent HDMI Splitter 1x2 4K | PcComponentes.com

HI

The report requested

Regards

[MUC]

A graphics driver always reads the capabilities of a monitor (EDID) over the cable and then offers the appropriate modes. Here we have this topology:

The HDMI splitter must therefore combine the EDID of both sink devices into one. I assume that this EDID mixing in the splitter follows the principle of the lowest common denominator. According to the diagnostic data, this leads to the Iris Xe graphics driver of the ASUS Vivobook thinking it may only use a maximum pixel clock of 80 MHz. This corresponds to 1280 x 720 @ 60 Hz progressive or 1920 x 1080 @ 60 Hz interlaced.

In my view, you have two options to resolve this.

1. Try to define (increase) the Video Standard in the ATEM Mini Pro as described on page 92 of the manual.
   
   Don't use "Auto Mode" but set it to 1080p60 for all inputs.
   
2. Let the Iris Xe driver on the ASUS Vivobook ignore the range limits by removing them as described here. The fact that the Iris Plus Graphics on the HP laptop works as expected is probably because this (old) driver ignores the limits anyway. This was apparently the case with older drivers. I also discussed this in the link.

[BillyClassTime]

I followed your instructions step by step and, indeed, I managed to get the monitor to work at 1920 x 1080 60Hz full resolution.

I’m really pleased to have found the solution.

I was surprised that a new laptop couldn’t achieve that resolution, but I now understand that it’s a matter of configuration on a deeper level.

Thank you for your time, and I hope this will help others solve similar problems.
