If you have a way for me to watch a movie and tell me where I should see an "HDR" logo that would be great. I want to make sure it's actually playing in HDR before I look for the horizontal lines.
I don't watch streaming content myself, only disc based UHD movies. However if you want to check whether something you are watching is in HDR, you simply press the action menu button during playback and then choose "picture". If it's an HDR program, you should see the greyed out words "HDR video" on the right side of the screen.
I do have acces to Netflix so I decided to check out some HDR content on there. Motionflow setting is disabled! If someone has the time and is interested, please check these timestamps. I'm curious whether you will see what I am seeing.
The Cosmo's Laundromat clip to which AustinJerry referred to is not available in my country so I chose Jessica Jones instead. I played the beginning of season 1, episode 1. At 2:08 there is a short scene in which the camera slowly moves forward in a hallway which lasts until 2:10. Keep looking to the left upper/mid part of the screen, in particular the brighter portions of the wall. The horizontal lines are clearly visible on my set especially since the camera is also moving. Now if I play this scene again, only this time with Motionflow set to True Cinema (the only Motionflow setting I would use since it doesn't involve motion interpolation), I have to look harder to see them but they are definitely still there. So IMO using Motionflow is not a solution but rather a way of covering up the issue. Btw pausing the program causes the screen to go dim which "breaks" the HDR effect, you have to see it in motion for the lines to be visible.
I also would like to point out that the lines are not visible on very bright or very dark portions of te screen. It's mostly when it's somewhere in the middle, not too bright but not too dark either. Therefore the lines will not be visible all the time. It really depends what's being shown on screen at that moment.
I also watched the beginning of Star Trek Discovery, again season 1, episode 1. Starting from 1:49, there is a scene of two women (hey, that's Michelle Yeoh!
) talking on a desert planet. Looking to the left part of the screen, I see the lines on and off depending what is on screen, sometimes they can also be seen on the right side. Now starting at 3:51 (and ending at 3:58), some sort of creature appears. At the moment when his tentacles appear, the lines are very visible as they clearly can be seen all over the screen. Again activating Motionflow makes them less visible but they do not disappear when watching this scene.
Would like to know if others are also seeing this.
