Thank you for your tests.
First: no, it's not ok the picture from your test, at the bottom (near the number 128-0) you must have 4 different lines, not one solid thick line. If you play the clip on a PC the difference it's obvious from TV screen, you have 4 distinct lines up to 1080 number.
Second: I put info on my pictures, LG fullscreen means the clip is played from my LG bluray player (used for comparison). So the pause is from my bluray player
Third: using original firmware (1.0.4-Q5EN.1000) brings
much better resolution, see pics in this post
Himedia 1.0.4 macro

Himedia 1.0.4 full screen

Himedia 3.0.1 using Kodi DVD player

The improvement in resolution is also visible in movies but this clip captures the exact situation (see lines in macro pictures are distinct almost up to 1080 mark).
So it's a firmware/driver issue (if it works with first firmware), not a malfunction from my mediaplayer.
I also put macro from Kodi DVD Player just for the sake of comparison.
I also welcome anyone feedback using not only this pattern but also other patterns mentioned (
4k pattern still don't look good on 1.0.4 4k pattern after a short modifyings settings looks
perfect with this firmware). It's important to use standard patterns to achieve constant/repeatable/comparable results.
Thanks again!
