I have interfaced and IP camera with resolution 1280720 to Raspberry Pi 4 4GB and 3.5 " TFT LCD chinese version with xpt2046 controller (touch ..which is disabled)(resol 480320). I have configured it with driver in repository given below link
I have played qHD videos on this setup and i have found that it is lagging significantly to make application look dull.
so i was desperate to know if it could be possible to solve this issue with higher SPI frequency of operation . But i could not set it any where and neither i could know how much is set by default. So if nay one has done it pls let me know how to change and where to look for it
