I have Lilliput LCD touchscreen 8,4" and I have problem with flickering.
I have tried all refresh rates and power sources(car battery, fortron PSU, original 220-12V adapter that came with lilliput).
When my pc turns on, lilliput also turns on but it flickers.
Than I need to press power off button on lilli , and then power on button, and everything is ok.
Sometimes there is no flickering when windows starts.

Where can be a problem?

Thank you!
