I cannot change the resolution of the Teamviewer session and it remains on 1024x768.

I am using Windows 10 and latest TeamViewer on both server and client.

RDP is available on the server and I can connect, screen resolution is 1920x1080.

There is no monitor attached to the server PC.

I can find the following items in Teamviewer logs when trying to change the resolution:

The quick and easy fix, for free, no hardware required. 😉 (Assuming that You want to change resolution on headless (no monitor attached) system.)

1) On the target machine, run "regedit".

2) Navigate to "\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\"

3) Find the correct "virtual" monitor. In my case it was NOEDID_8086_3E91_00000000_00020000_31013^53F8D5930757FC6478DA395B2023D3E0, but Your mileage may vary, and probably will. 🤨

If not sure, try to navigate to "00" subfolder and look for PrimSurfSize.cx and .cy - if it matches the undesirable small resolution, You probably have Your guy. 🤔

If still not sure or feeling lucky and lazy, just delete all the folders under "Configuration" and restart the PC. The only one which pops up after restart is definitely THE ONE. 😁

4) Navigate to "00" and change PrimSurfSize.cx and PrimSurfSize.cy to the resolution of Your choice. In order to calculate the right value, run Windows Calculator and switch it to "Programmator mode", in which You type the value in decimal and You will see the correct value in Hexadecimal. Or just use 780 for .cx and 438 for .cy, which will get You a nice, 21st century, 1920 x 1080 resolution.

5) Go deeper, to the second "00" and repeat.

6) Now change the resolution as You are used to and voila, now and forever - You are happy. 😍

You are welcome. 😎

Hi @David_Style

I am experiencing the same or similar issue as you. Please see the thread here:

https://community.teamviewer.com/English/discussion/124466/screen-resolution-not-changing

I have not found a solution yet, but I am working with a moderator to get it resolved. Please follow that thread for updates.

Thanks, it is working fine for me!

Hello @dmezei,

You can now define the window size, as well as the remote screen resolution. This might help you to fix this issue.

Please find how to proceed here:

📄 Fix size and resolution issues

Hope this will help!

All the best,

I have the same problem.

I connect, use the toolbar to change the screen resolution, but it remains at 1024 x 768.

I go into windows control panel and try to change it there, but it still stays at 1024 x 768

While On teamviewer, I can RDP to the remote computer and change the screen resolution, and it works and shows in TeamViewer at the higher resolution, but when I disconnect the RDP, it goes back to 1024 x 768.

@JeanK I am not talking of 1024 x 768 as just the default on connection, The computer will not allow any other Screen resoultion than 1024 x 768 with Just TeamViewer connected.

This is just since the last update, previously I could select and see any higher resolution when using TeamViewer.

Thank you so much. I've been messing around with a second computer and don't have another monitor for it and it has been driving me crazy looking at a little square screen. Thanks!

You are very Outerstanding Genius!!

I am on MacOS and I don't have advanced properties, so I guess I have to code stuff for a software that costs me [removed per

Community Guidelines] euros a year myself. I'm kind of frustrated by this, rightfully so, in case you didn't catch.

I've made a PowerShell script to easily change the resolution, it will go through all virtual displays and set them all to 1920x1080
Open PowerShell-ISE as Admin and press play or run the .ps1 file with Powershell as admin.
Log-off to apply.
You may change to the desired Resolution changing the Target Resolution Values:

# Target resolution
$targetWidth = 1920
$targetHeight = 1080

you can go back to the "optimal" 2004 resolution by selecting it under:
View → screen resolution → Optimal resolution

# Define the registry base path
$registryPath = "HKLM:\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration"

# Target resolution
$targetWidth = 1920
$targetHeight = 1080

# Fetch all subkeys under the registry path
$subKeys = Get-ChildItem -Path $registryPath

# Loop through each subkey
foreach ($subKey in $subKeys) {
    $subKeyPath = $subKey.PSPath
    
    # Fetch inner '00' subkey
    $innerSubKeys = Get-ChildItem -Path "$subKeyPath\*" | Where-Object { $_.Name -like "*\00" }
    
    foreach ($innerSubKey in $innerSubKeys) {
        $innerSubKeyPath = $innerSubKey.PSPath
        
        # Update the required properties
        Set-ItemProperty -Path $innerSubKeyPath -Name "PrimSurfSize.cx" -Value $targetWidth
        Set-ItemProperty -Path $innerSubKeyPath -Name "PrimSurfSize.cy" -Value $targetHeight
        Set-ItemProperty -Path $innerSubKeyPath -Name "ActiveSize.cx" -Value $targetWidth
        Set-ItemProperty -Path $innerSubKeyPath -Name "ActiveSize.cy" -Value $targetHeight
        Set-ItemProperty -Path $innerSubKeyPath -Name "DwmClipBox.right" -Value $targetWidth
        Set-ItemProperty -Path $innerSubKeyPath -Name "DwmClipBox.bottom" -Value $targetHeight
        
        Write-Host "Updated resolution for $innerSubKeyPath to ${targetWidth}x${targetHeight}"
    }
}

Thank You, Thank You & Thank You

I am tired of messing with those little dongles that only work sometimes. So far this has worked on all the Windows machines we have tried.
