I appreciate the reply. So I've tried the latest Armbian_20.02.7_Tinkerboard_buster_current_5.4.28_minimal.img and the issue persists. I'll try the latest nightly dev build which looks to be Armbian_20.02.7_Tinkerboard_bullseye_current_5.4.28 later tonight and see how that goes and report back. As Far as the screen-resolution guide you've pointed me to. I can't even get started as using xrandr doesn't seem to work. Again I haven't tried this with the latest so I'll try again later tonight and see how it goes. I was happily running ROTT1.1 (RetroPie on the Tinkerboard) which is using that 4.19.21 version. The end goal is to get this running RetroPie again. The first fight in a long battle ahead of me it would seem. xrandr --listmonitors Can't open display Why just the Samsung TV I wonder? I've hooked this thing up to many TVs from 720p to 4k resolutions using all kinds of refresh rates.

So I have armbian installed on a tinkerboard and have had absolutely no issues with it until I bought a new Samsung 7000 series TV (2019). For some reason this TV does not recognize the signal coming from the tinkerboard. For the life of me I cannot figure out how to get this to work. I notice a few references online about being able to force a resolution but nothing related to the rockchip boards. Is there an equivalent way to force a display resolution as in this article? https://docs.armbian.com/Hardware_Allwinner/#how-to-reconfigure-video-output I'm running 4.19.21-rockchip 5.76 I've also tried kernel 5.4.28 as well and it's the same issue. Just for kicks I loaded Lakka on there and it works just fine so I know the board itself is working properly. I don't even know where to begin. I was hoping someone could chime in and point me in the right direction.
