Hi Nabil,
I was able to run TestPattern sample OK at 2160p50 on my machine. My setup is CentOS 7.6, kernel 3.10.0-957, Desktop Video 11.2 with DeckLink 4K Extreme 12G.
From the Desktop Video Setup application, can you check your output link setting is correct (single-link/dual-link) and that you are outputting YCbCr 422.
Regards
Cameron
