@theparasol: Please check my previous posts. I wouldn't fight for that just because it is in box specification (the output is as I want it, just that flicker problem).
@Erik:
It should work without autoresolution, as I want a single 1080p50 on output. I tired autoresultion only as suggested by dirocca. And I've modified the plugin to support 1080p50. But it did not helped with a flicker problem.
