Applications get shrunk to a Quarter Screen Size when TV, or AVR is Switched Off

[kncowans]

Hello all

I Hope you are Well.

I have a HTPC with the 'ROG STRIX B760-I GAMING WIFI' Motherboard and an Intel i7 12700K and 64GB DDR5 Memory.

I am running Windows 11, up to Date as of Today.

The HTPC is connected, via HDMI, to a Marantz NR1609 AVR and then to an LG 49SK8500PLA TV.

I run Plex HTPC for my Media which is also up to Date.

The HTPC runs 24/7 so only the AVR and the TV are Switched Off.

When the TV, or the AVR is Switched Off, when they are Switched On again, Plex HTPC is reduced to a Quarter of the Screen Size appearing in the Upper Left of the Screen.

I run my HTPC at 4K60.

It used to work fine, however, annoyingly, the TV, AVR, Windows 11, Display Drivers and Plex HTPC all received Updates in the same 24 Hour period making Troubleshooting difficult.

Has anyone come across this Issue?

Thanks in advance

Kevin

Hello kncowans,

Thank you for posting in Intel community Forum.

For me to further investigate this issue, please help provide the following details:

1. Are you using the onboard Graphics of the processor?
2. Just to check, the display in the monitor of the PC is still the same?
3. How did you connect the PC to HTPC?
4. Please help generate the SSU logs of your system for me to review the hardware and installed drivers. Please refer to the link below on how to generate the logs:

Hello

Thanks for the Reply.

1.  I am using the Onboard Graphics (UHD 770), I have no other GPU in the PC.

2.  The Display is the same, I only have One Monitor, the Main TV (LG 49SK8500PLA)

3.  The PC and the HTPC are the same PC.

4.  I have attached the SSU Logs to this Message.

Thanks in advance

Hello kncowans,

Thank you for the update.

Based on your reply, let me ask the following questions.

1. If you remove the AVR and directly connect the TV, are you going to have the same issue?
2. Based on SSU, you are using the latest drivers. Have you tried rolling back the driver and check if you will have the same issue? Here are the stops on how to roll back the driver in device manager: How to Roll Back a Driver to a Previous Version in Windows® 10 and...
3. You can also try installing the latest driver using DDU method. Please refer to the links below on how to perform the DDU method:

Hello

Thanks for the Reply.

I believe that this specific Issue is now Fixed, however, I need to do more Testing.

I have another Issue, regarding the i226-v Network Adapter and it losing Connection when the TV is Switched Off but I will Post that Issue in the Networking Forum.

Thanks

Hello kncowans,

Thank you for the update.

I am glad to hear that, and you can have a couple of days to observe the system.

Let me check, how were you able to fix the issue., did my last recommendation help you fix the issue?

Regarding your other issue, please post another question under wireless threads to address that properly.

Hello

Thanks for the Reply.

Unfortunately, none of your suggestions worked to address the Issue.

What I ended up doing was to Edit the Registry and adjust the Resolution Settings for the Dummy Output that Windows 11 uses when no Monitor is detected.

This solution has, thus far, been working.

I did Post a Thread regarding the Issues with the Network (Wired - I226-v) Disconnecting, however, one of your colleagues advised me to Contact Asus directly.

The Tread is here:

Hello kncowans,

Thanks for the update. I'm sorry the initial suggestions didn't work, but I'm glad you fixed the issue by editing the registry for the dummy output resolution in Windows 11.

Regarding the network disconnection, it's good that you posted a separate thread and were advised to contact Asus directly. We offer basic troubleshooting for OEM devices, but the manufacturer's support team is best equipped to handle technical and warranty concerns.

Since you've resolved the issue, I'll close this thread. If you need help in the future, please submit a new inquiry, as this thread will no longer be monitored.

Sincerely,
