flashing black screen when i try to use samsung dex with usb-c to hdmi

i have a galaxy s10 plus and a usb c to hdmi so i get no input lag for emulators i play on my phone to the tv i have no problems doing this on other tvs but on my roku tv c124x tcl model 50S421 when i plug the hdmi into the tv it goes to samsung dex (like usual) and then the screen flashes black and back to normal very slow but in like a pattern it doesnt do this in any other device i plug in just my phone i tried all other hdmi ports too still does it its very strange quite the conundrum 🧐
