overscan issue

[mar4]

I have Intel iris xe graphics on my Lenovo t14s. I try to connect this to an external display (Acer 4K monitor) over HDMI, but I keep having an overscan issue no matter what resolution I select, even with the native resolution or anything smaller like 1440p or 1080p. Changing the refresh rate doesn't fix the issue. I have the latest drivers (32.0.101.6559). The display works with all other computers I have tried.

Hi mar4,

Thank you for posting in the Community.

I understand you're experiencing an overscan issue when connecting your Lenovo T14s with Intel Iris Xe graphics to your Acer 4K monitor over HDMI. 

To better assist you, could you please provide the following details:

1. When did you first notice the overscan issue? This can help identify if any recent changes might have caused it.
2. Have you tried using a different HDMI cable or port on the monitor? Sometimes the cable or port can be the issue.
3. Have you checked for any firmware updates for your Acer monitor and what is the exact model of your Acer Monitor? Firmware updates can sometimes resolve compatibility issues.
4. Would you be open to trying a different connection type, like DisplayPort, if available? This might bypass the issue entirely.

Best regards,

Thanks for the quick reply.

1) The issue started once I got this new Lenovo laptop with Iris Xe graphics. It never worked! The original Intel Graphics driver (apparently automatically installed from Lenovo update) didn't work, the latest driver, manually installed from Intel's website, doesn't work either.

However, all my older PCs worked just fine (e.g. an older Asus laptop with Intel 620 graphics and an even older laptop with Intel HD Graphics 4400).

2) Yes, I have tried different HDMI cables. There is just one HDMI output on the laptop and one input on the screen.

3) This is Acer B276HK. There isn't any firmware update available.

4) The Lenovo laptop has only HDMI (surely the DisplayPort works from my desktop PC), but I doubt there is anything wrong with the monitor, since all other computers work fine, just this Lenovo with XE graphics doesn't.

This seems to be some sort of compatibility issue in the Iris XE graphics, there are many topics online where people complain about such overscan issues on this graphics adapter type. Hopefully, you will fix this with a driver update soon.

Hi mar4,

 Thank you for getting back to me. I want to clarify the following questions:

1. Could you please let me know what refresh rate you have set when using 4K resolution?
2. Does the overscan issue only occur at 4K resolution, or does it happen at other resolutions as well?
3. What HDMI version are you using?
4. Have you tried clean installation of the driver from Intel or Lenovo? This may be a conflict within old drivers and new drivers within your system. Follow the steps here: (Clean Installation of Intel® Graphics Drivers in Windows*)

I would suggest trying the following steps here in this link:

Here's the steps for downloading the Intel Graphics Command Center:

1. Download and launch SSU.exe. 
2. Check the box for "Everything." 
3. Click "Scan." 
4. When the scanning is complete, click "Next."

I replied here, but it soon disappeared, what happened?

[mar4]

1) 60Hz. However, the issue remains with other refresh rates as well.

2) At every resolution, for example, 1080p, 1440p and 4K. 

3) No idea of the HDMI version, I can't find this anywhere in monitor settings. Yes, I know earlier HDMI versions can't do 4K 60Hz, just like my older Laptops are limited to 1440p, however, this overscan issue happens also at lower resolutions, but only on this laptop having intel XE graphics.

4) Yes, I just did a clean install (with erasing existing drivers and settings) to Intel XE drivers 32.0.101.6632, no difference, unfortunately

This is everything Windows tells me about the screen:

The scaling option in the Graphics Command Center actually works! However, the image quality suffers, apparently because it can't scale to native resolution and all pixels become blurry, so this doesn't look like 4K at all, I would say any 1080p display looks better. However, perhaps an acceptable workaround, meanwhile you can fine-tune the drivers and fix the compatibility issue.

Intel System Support Utility results are attached

[mar4]

1) 60Hz, as well as other refresh rates.

2) 4K and other resolutions as well

3) I don't know the HDMI version

4) Just did, again, to 32.0.101.6632, no difference, unfortunately.

The scaling in the Graphics Command Center works, but the scaling doesn't make it native resolution, all pixels are blurry.

Apparently I can't include the System Support Utility result file. If I do, the reply is automatically erased.

Hi mar4,

Thank you for your patience. To further investigate, could you please provide some additional information by considering the following questions?

Monitor Scaling:

Does your monitor have any settings related to scaling? It might be helpful to perform a factory reset on the monitor to see if the default configuration resolves the issue.

Display Cables:

Based on the native resolution of your monitor, I suggest using HDMI 2.1 or DisplayPort 1.2 - 2.1 cables to determine if the issue is related to the display cables.

Yealink Virtual Display:

I noticed that you have a Yealink Virtual Display. Could you test your computer without this software to see if it affects the issue?

IGCC Log:

Please send us the Intel® Graphics Command Center (IGCC) log with and without the Yealink Virtual Display (disabled in Device Manager and after a reboot) while the monitor is connected to the laptop.

Scaling Options:

Try different scaling options (display/GPU scaling). The default is usually displaying scaling and maintaining display scaling as the method.

OS Advanced Display Settings:

Could you check the advanced display settings in your operating system regarding scaling options?

Older Graphics Drivers:

If possible, please try installing older graphics drivers from Lenovo to see if that resolves the issue. Intel Graphics Driver for Windows 11 (Version 21H2 or later), 10 64-bit (Version 21H2 or later) - ThinkPad - Lenovo Support US
