Hello,
I recently bought a Zotac CI622 nano and I succeed to install LE 10.0.1 with many difficulty but screen still get black.
First, I try LE 10.0.0 without success. Let's go with 10.0.1!
I use this thread to help me: LE 10.0.1 / Rpi4 / No picture after update from LE 10.0.0
To boot LE, first I use run mode from USB key and I have the same behavior: Black screen after Xorg start.
I change "quiet vga=current" with "nomodeset" in syslinux.cfg: I see Kodi in 800x600 on my Samsung UE40MU6105K with a WxH 3840x2160@60Hz. 
I have to change same kernel parameters on Debian live 11.2.0 to start but in 800x600 too.
After this, I change the install boot parameters with nomodeset in sysminux.cfg and I succeed to install LE on SSD drive.
But now, when I start LE on SSD, TV screen goes black even if LE start. I think Xorg bug like on raspberry PI.
If I boot with Debian live, I don't see any grub.cfg or syslinux.cfg to change kernel parameters on SSD.
Now, I don't know what can I do to use LE on this Zotac.
Can someone help me or give me a direction to find a solution?
Thanks a lot to read me.
Razli
