    Okay, I am having some issues. i will try and go to as much detail in text as I can but the attached short video shows what I am experiencing and has descriptions of the issues as they arise.

    First off, for those they may or may not know, I am not a normal guy (big shocker) and I dont have a normal setup. I am almost always pushing MP so it is not uncommon for my issues to be the most random SOBs seen, and for that I apologize. I also want to say up front, thank you for each and every one of you in advance for helping. It means the world to me, so thank you.

    Okay, as a heads up for those of you who have not read my post from last month (https://forum.team-mediaportal.com/threads/mp-crashes-on-new-4k-htpc.134090/) I have a Skylake i5-6500 on a Gigabyte Z170-Gaming 7 motherboard. This is important because my HTPC is pushing 4K at 60hz. The motherboard is important because I was doing it CPU's HD 530 GPU and that motherboard has a HDMI 2.0 port on it not just a 1.4a. HDMI 2.0 is what allows for more than 30hz at 4K using HDMI. Displayport 1.2 also allows for 4K at 60hz, but hardly any TVs have Displayport.

    I had issues using the CPU's HD 530 that never got fixed, but what I did do was buy a GTX 960 (GTX 950, 960, 970 and 980 all have HDMI 2.0) and that fixed all of those issues that I previously had. In fact, everything seemed to be great until I played some TV episodes.

    What happens is when I play certain episodes it messes up the color and resolution, and when I play other episodes it fixes the problem and it looks okay again.

    Oddly enough when I use a networked mouse in MP it temporarily fixes the issue for about 5 seconds, but not when I use a mouse connected to that PC.

    Also, I get some errors when I play certain other episodes.

    Below is the media info for each of the TV episodes, the Join or Die that breaks it, the 24 that fixes it and the Two and a Half Men that gives an error before playing. As a side not for that error. It does play the video, but once it ends and I go to the next episode I get the error again, but then MP hangs and I have to force close it.

    Keep in mind that while watching video, aside from the last text bubble, when text is on the screen, the video is frozen at that frame and not in real time. Soon as text goes away it is in real time again.

    Heya :)

    First, thanks for an excellent report. Your description, videos and log files are excellent - couldn't ask for better. (y)

    Executive summary: based on the information you've provided, I think almost everything you've described is primarily related to refresh rates. The only thing I can't explain is why/how the network mouse temporarily fixes the situation.

    Refresh rate change data...

    On startup:

    [2016-05-02 12:23:15,762] [Log ] [MPMain ] [INFO ] - CycleRefreshRate: unable to change refresh rate 50Hz for monitor 0


    The above behaviour (< 30 Hz => okay; > 30 Hz => green + distorted) seems consistent with an HDMI link or TV that can't handle 4k at 60 Hz. By Occam's razor, I propose the hypothesis that the HDMI link or TV input is actually HDMI 1.4 (which can handle up to 4k @ 30 Hz for non-3D content) instead of 2.0 as you think.

    I'd agree that your GTX 960 can output 4k at 60 Hz. However that's only half the equation. The TV also has to have an HDMI 2.0 input... and support displaying 4k at the refresh rates that the HTPC is using. So, what is the model number of your LG TV? Methinks it's time to check its specifications... ;)

    I have it plugged into the HDMI 1 slot that says 2.0 out next to it.

    I guess it could be the cable but I bought it brand new and made sure I got a high speed one. Cost like $40.

    Okay, just replying to another thread. Will take a look at the specs in a moment. In the meantime, you could try to find videos with different refresh rates - eg. 24 Hz - and see if they play. Alternatively, check what happens if you use the NVidia control panel to manually change the desktop resolution + refresh rate.

    I just realised that at the start of your video you had the desktop showing fine... and presumably it was 4k @59 Hz. That contradicts my hypothesis. Still, it's clear that something in the chain doesn't support 25/50 Hz, else why would that refresh rate change have failed?

    The TV specs seem to be somewhat ambiguous about exactly which refresh rates, HDMI version and/or bits-per-pixel inputs are supported. All I can find in the spec sheet from LG is "TruMotion 120Hz".

    Another idea to try...
    Do what you do to trigger the green distorted screen, then go into the TV menus and see if you can find any panel/menu which tells you what resolution and refresh rate the TV thinks it's receiving/using.

    No menus to tell me. I disabled Dynamic Refresh Rate in MP and when I do that, even playing the episode of 24 will not fix it

    Okay, so. Here is what I have done so far. I turned DRR back on. Went into MP (it looked bad at launch). I went to the 24 episode that fixed the refresh rate so MP looked good again. I then exited MP while looking right (remember it starts back either right or wrong by how it was when you last exited) and turned DRR back off. I then went back into MP (looking right) and played the Join or Die episode that always breaks it. I watched the whole episode without it messing up once.

    Two and a Half Men still gives the error "Syntax Error at Line 1738!".

    I think these two things confirm I was onto something, even if I'm not completely right. Something about MP changing the refresh rate has the capacity to introduce or remove the problem. It really is a bummer that the TV won't show its input settings.

    Did you try the other suggestions?
    (Changing the desktop resolution and/or refresh rate, and playing other videos with different refresh rates to see if you can figure out whether the behaviour is consistently correlated with the video frame rate.)
