If you have a large or non-standard resolution (for example, 3440x1440), you might have issues with parts of the interface not being visible, puzzle list not loading, and so on. To fix this, you need to change the resolution to 1920x1080. Problem is, you'll have to do it via Windows registry modification, since the game will display empty resolution values in the Options menu, not allowing you to change anything in-game.

1. Close the game, if it's running.

2. Open registry editor (Win+R, type regedit then click Run):



If you don't have experience working with Windows registry, back it up before doing anything (see these instructions[support.microsoft.com] from Microsoft)

3. Navigate to HKEY_CURRENT_USER\Software\Konstructors Entertainment\Nonogram - Master's Legacy

4. Change the value for the following registry keys (read Notes below in case you're unsure about what you're doing):

• Screenmanager Resolution Height_h(numbers): should be changed to 438
  
• Screenmanager Resolution Use Native_h(numbers): should be changed to 0
  
• Screenmanager Resolution Width_h(numbers): should be changed to 780

This is how it should look:



Notes:

• To edit the registry key value, double click the corresponding key -- or click it once to select and hit Enter
  
• All values are specified in hexadecimal base, which is selected by default
  
• I'm not sure if a bunch of numbers after the registry key name is generated randomly for each machine / installation, or they're the same on all machines / installations. What I'm saying is these might be different on your PC
  
• No need to manually save anything, the changes are applied in real-time

5. Run the game, it should work properly now in glorious 1920x1080 resolution.
