Display problems

Hi I order this display from AliExpress (link below) now I'm thinking if something is broken or is my code/config wrong because I don't have any picture on this display, I used normally LED and UVleds as backlight but it didn't give me any picture...

I used same code and physical setup as what I did with last LCD with good result. (expect that LCD had few cracks from shipping, what was reason to change it). That last display was original NanoDLP VISRIC LS055R1SX04

HDMI to MIPI driver controllee S2.2 and Raspberry Pi 3 with NanoDLP Shield V2.1

Please help me with confix.txt if there is any problem.
Ill send my textfile in next post

Screen now

Re: Display problems

My number 1 suggestion would be first to make sure you have a good working screen.

Plug it into a PC that is capable of outputting 2K resolutions and apply a bright backlight to the back of the screen. Use a dialog box with a lot of white on the screen and move it around. You should see it on the LCD.

Start there.

No sense in trouble shooting the Pi if you don't even know your screen is any good.

Thanks! I readed some of your posts in another topic, and same time wondered this what you just said..

That would not be first time to try play with broken stuff!

Btw, Is there any manufacturer who do premade UV-backlight 2k screens with VERY straight glass??
Im too scared to do that by myself :DD Too much bad videos about that and few own experiences when tried fix phones LCDs... :7
