rx550 and rx570 gop do not detect my tv during bootup

Hi guys, I have rx550 4G and rx570 8G gpus with 1.70 gop and LG OLED48C11LB tv. Nither one can detect my tv during pure uefi bootup if tv has deep color in hdmi settings set to "optimize for 4k". If it is set to "off" everything goes fine. Is there any way to fix this problem?

Thank you, Dmitry
