What to do if the error message 'Out of Range' is displayed on my Bosch UML-323-90?
- SSierra WheelerAug 10, 2025
If you see the 'Out of Range' error message on your Bosch Monitor, it means your PC is using a resolution or timing mode that the monitor doesn't support. To fix this, change your PC's timing mode to one of the following valid combinations: 640 x 480 (60/72/75Hz), 720 x 400 (70Hz), 800 x 600 (60/75Hz), 1024 x 768 (60/75Hz), 1280 x 768 (60Hz), 1280 x 960 (60Hz), 1280 x 1024 (60Hz), 1366 x 768 (60Hz), 1600 x 1200 (60Hz), or 1920 x 1080 (60Hz).
