It is difficult to choose a model on Aliexpress, as the specifications are simply false, I have seen the same panel marked as 4000nits and another as 8000nits, both unrealistic for being too low and too high, the best option is to search on alibaba for manufacturers of their own panels to get reliable data
Anyway, my main doubt was about the refresh rate (not the scan rate which is always 1/8) I have seen panels marked as 480hz, or 900hz , 1200hz and 4800hz, I wonder which will be the best option for rPi, I think the lower the better? because rPi can barely overcome 200hz @11bits.
In any case I have found out all the panels marked as 4800hz are driven by PWM chips (icn2153, icn2153,mbi5153 ) so they are totally excluded for this project.
