2. Here's why:

This problem is caused by one of the following reasons:

• The screen resolution is too low.  Lumion requires a minimum screen resolution of 1920x1080.
• Custom app scaling is applied in Windows.

Follow the steps below in Section 3 to fix the resolution.

3. Check if the screen resolution is too low:

Lumion will display an error if:

• The screen resolution is too low:
• 
  
• the DPI scaling is too high:
• 
  

To troubleshoot this:

3.1: Close Lumion.

3.2: Right-click on an empty area of the Desktop and pick ‘Display settings’ (examples shown using Windows 11 unless otherwise stated): 

3.3: Change the ‘Display resolution’ to a minimum of 1920 x 1080:

3.4: Also, ensure that, if the ‘Display resolution’ is at 1920 x 1080, the 'Scale' of the display is set to 100%.

4. Check if custom app scaling applies

4.1:  Close Lumion.

4.2:  See this guide:

• External Link:  How to Fix Blurry Apps on Windows 11 or 10?
