Quote from: See_Mos on Jul 19, 2021, 04:46 PMI have now tried various simple level shifting. A 1K resistor in series with each of the five signal leads allowed the display to work, potential dividers were less good, as was reversed diodes across the 1K resistors. All three methods caused ringing or poor rise and fall times. A 3v3 regulator and series resistors might work but I suspect distorted drive will still be a problem.
