If your DAKboard Wall Display, or CPU screen appears larger than normal or blurry, the resolution may not be set correctly. By default, the resolution is set to "Auto" and will try to guess the resolution of the connected monitor/TV. Depending on the type of monitor or TV, the resolution information may not be available, resulting in a blurry or enlarged screen. To fix this, manually set the resolution on your DAKboard Wall Display or CPU.
In your DAKboard account, click on "Displays", then click the more actions button next to the desired display and select "Settings":
Note: You will need to be connected to the same wifi network as your DAKboard device in order to access the settings.
On the display settings page, scroll down and find the "Screen" section, and set the Resolution to "1080p":
Scroll down further and click the "Save changes" button. Restart your DAKboard Wall Display or CPU by unplugging the power and plugging it back in. When it starts back up, the correct resolution should be in-use.
Advanced/DIY Resolution Settings
For those who have built their own displays, or have DAKboard displays that were purchased prior to 2017, you may need to manually set the resolution. This can be set by following these steps:
With a USB keyboard plugged into the unit:
- Press the Option key (could be a windows logo, or Alt key depending on keyboard). This should bring up a menu in the upper left of the screen.
- Use the arrow keys to go down to "Accessories", then arrow right, and down to "Terminal" and press the Enter key. This should bring up a black terminal window.
- Enter the following command: sudo nano /boot/config.txt then press enter. This will open up a file.
- Use your keyboard arrows to go down to the bottom of the file, and on a new line, add the following lines:
- Then press ctrl o then enter and then ctrl x then enter (this will save and quit out of the file)
- Lastly, type sudo reboot, and press enter. This will restart the display.
When it comes back up the resolution should be back to normal.
