Hi, I have a problem with getting display on LVDS screen. I have ASRock A320TM-ITX motherboard and AMD Ryzen 3 3200G with iGPU. Motherboard has LVDS connector, which seems to be 2ch 8bit. I bought LG LP101WH1-TLB4 display; which is LVDS 1ch 6bit, resolution 1366x768@60Hz; and 2ch 6bit 30 to 40 pin LVDS cable.

Problem is, that I have backlight, screen is recognized in OS, but I don't get any display. First it started with1920x1080@60Hz resolution, I've changed it down, but still didn't get display. In Radeon control center it has name "LED1920x1080" and EDP connector. I have tried changing to 6 bit color, but there isn't any option, as well as custom resolution doesn't work. I cannot see in BIOS any options reffering to "built-in" display and I don't know what to do. Probably I have another LVDS screen in my laptop, but I must disassemble it.

So my question is how to get this to work alltogether?
