Display is fuzzy, with occasionally white signs blurring the IP-address.
Please contact service@sunfounder.com to provide your detailed address to get a OLED moudle.It is recommended to run a command to turn off the OLED screen when it is not in regular use, and turn it back on only when needed.
This can help extend the service life of the OLED screen.
I contacted the service department and they decided to send me a new display.
Thanks for your quick and excelent reaction!
