Display 8.9 mono 4k

Dear,
I installed this TM089CFSP01 lcd on a Phrozen shuffle XL printer. Using raspbarry PI3 with Nanodlp and the config.txt file I use is not correct because horizontally deformed images are displayed on the LCD. Calibration is Ok but when I view a layer, for example a simple circle in the display an oval appears. I tried to replace LCD, Driver, raspberry pi 3 but the result is always the same. I have updated my raspberry but the problem remains and I believe it is in the config file. I write the configuration I am using found in this forum for LCD 5.5. I hope someone can give me useful advice to solve my problem.
Thank you in advance

Re: Display 8.9 mono 4k

After changing display make sure you have regenerated the plate before print.
If calibration is ok, frame display also should be fully functional.

Having images both calibration and plate frames + a debug file will be quite helpful to find misconfiguration.

Re: Display 8.9 mono 4k

Unfortunately I needed a car and couldn't make any other attempts. I needed the 4k and now it is assembled with another motherboard and software from chitu. In the future, however, I would like to use nanodlp or build a machine with nanodlp firmware because it is much richer in options. Thanks for your availability, I will definitely test the config file later.
