Green lines messing up ALL video playback (windows 10)

[Superfly Original]

I have had this problem fro a while now. I now have my computer connected to my monitor and when I play just about any video I get this green lines and stuff. Now it seems to just appear when I display through my monitor.



For some reason I have a bad feeling about this.

They seem to be following Y level contours so the chances are you have a faulty green channel DAC on your video card. Less likely is a video memory fault. Can you try an alternative video card?

Hi, I really appreciate the fast response. I have week old threads elsewhere still un-accompanied by responses.

That said, treat me as if Im your Grandmother because I know very little about video cards. Heck, I dont even know where mine is! I did just post an image of my laptops specs. Assuming what you suspect most, for the sake of argument what if you're correct? is there anything I can do?

Hi,
what video player are you using. And did you try some different video player ? It is easiest thing you can do. And if the results will be same so it can say something. Try f.e. MPHC or Potplayer.

Bernix

Oh, yes-- I have tried plenty like VLC ect. This has been going on for like 2 weeks.

update: I have tried on potplayer and same issue.

[Bernix]

My friend had similar problem. Try change in potplayer video->video renderer to built in OpenGL. It helped to him, but his problem was bit different. I dont believe too much it will help. Possibly really some problem with Graphics card. I am sorry.

Bernix

What came before that? before he enabled The GL thing? i just put it on but forget what was selected before hand

and thanks for the replies

PS: why potplayer? specifically ?

[Bernix]

He had a green spots but only at upper right corner. Custom EVR didnt helped, Direct3d same but only open gl solved it.

How can I know that it is solved? does a refresh/restart computer have to done or does it fix right away if it worked ?

[Bernix]

No you dont need restart. Nor potplayer. It apparently didnt works

Yep, didnt work for me. I will continue trying to figure this out later tonight.

Thanks for the help thus far!

Turn off all the video "enhancement" features in Intel's graphics setup applet.

Just tried all of them I could find, no luck...

In VLC, use Windows GDI as the video output device. Does the problem persist?

Seems so... what the heck could this be!

Any ideas why this problem shows up on the monitor display, but the built in screen does not show it?

Then the problem only affects the laptop's HDMI out. Your laptop uses a different connection for its own screen.

Cant really tell if that is good or bad news!

So far the only thing that helped is lowering the refresh rate.

What refresh rate helped? The usual refresh rate for LCD monitors is 60Hz, and if I read the specs correctly, your laptop's Intel HD 4400 graphics supports a maximum refresh rate of 60Hz for HDMI at HD monitor resolutions.

Correct. And when I lower the refresh rate on properties (under monitor display setting part) and now its mostly gone. But, im still completely lost as to what it actually is (the problem) im guessing my quality is reduced due to refresh lowering.

This just happened so who knows if this is going to remain or not.

I was saying that lowering it to 50hz seemed to have solved the issue. It is by default higher, but I cant stand the lines. Id rather have less quality or sharpness.

What is the frame rate for the video itself? If you don't know, open the video in MediaInfo and click on "View", then "Text" and read the resulting report to find out. (VLC sometimes reports the frame rate incorrectly.)

I notice one screenshot is labeled 1280x720 while the others are labeled 3840x2160. Why 3840x2160? Are they from a UHD/4K video? Are you are using a UHD/4K monitor?

That is just because I took some snapshots from an outside device. You can oddly enough see how the lines are effecting even the menu while watching the video

Have you tried re-plugging the HDMI cable at both ends, or tried a using different HDMI cable?

Ive tried replugging ect. Im going to try a new cable soon.

[Bernix]

Havent you too long HDMI cable ? Shorter is better I think. It can do mess if is it crossed and with bad cable shields.
Try to narrow the cable.
0.01 percent chance but at least you can try it

from web

I finally Have found the solution to my problem.
I clicked control panel-> adjust screen resolution-> advanced settings->list all modes
and I choose
1920*1080, True color (32bit) 29 hertz (interlaced)
and the green lines are gone, still one little problem with the edges of the screen are not shown but its not a big deal.
29Hertz ???

Hey, may I ask you what you came from? you went from how many herts to 29? because my screen shakes when its that low

Wow so far mine is working too. I changed from 60 to 59 in the way you said to. And no green lines so far! Thank you so much

[Bernix]

29 hertz I found on web I was very surprised such a low refresh rate.
Glad it helped.

Yeah im surprised yours is that low. Going to 59 from "graphics properties" did not work for me. But doing so the way you said did work.

You're a savior!

[Bernix]

It wasnt my refresh rate, I have 60 Hz. I found that help on web. I made bold 29hz, because I can hardly believe it.
