Hello guys . First sorry for my bad english .
Im wondering if there's anybody who is fammiliar with vsync and hsync on vga /av signals. I want to convert parralel RGB to vga/av but the problem is that the signal is designed for non-common used LCD screen. It is Sharp LQ070T5DR2 used in mmi 2g system on Audi https://datasheetspdf.com/mobile/921629/Sharp/LQ070T5DR02/1
I have deserialized signal and tried to use ADV 7123 DAC to convert it to VGA but the problem is that lcd uses falling edge HSYNC /VSYNC that i inverted but my monitor shows unsupported resolution . Its 480x240 . Im wondering if there's some IC that can rescale it to bigger resolution or some way to put this signal to AV input. I dont care about the quality, i just want to see my car's system for A/C seat heating and etc . And switch between mmi system and external Box with android auto and touch screen . Thank you .
