My display is wonky and wonkier it gets for each day. Is there a way to find out if it's the screen or the video card that is BSODed? I haven't been able to borrow another screen, which would of course be the easiest way to find out.
It started with short, thin lines showing up in columns where there was a solid or close to solid color. Pure black, pure white and yellow weren't affected. Now colors are garbled and solid color areas flicker (like the chrome of programs and windows, old Windows gray style). How the problem manifests itself is affected by the display mode I choose on the screen. In Standard and sRGB mode light lines are rolling down the screen (much as it could look at a badly tuned old fat TV). If I choose Movie or Dynamics the rolling lines go away but colors look like they were designed by Disney. The problem gets worse if I leave the computer idle. If I'm not working at it I leave a movie on so something happens on the screen. I haven't made any changes lately, neither to the computer or its environment. Tried to turn speakers off and so on. No biggie, I was contemplating getting a new screen anyway, so I'm thinking of getting that first, even if it's more expensive. But it's the worst time of the year, shops are jammed full with people, things get sold out and since I don't keep up with hardware it takes me some time to figure out what I want. WARNING: I really suck at hardware, so you need to talk to me like to a baby. |

You could try switching OS if you have more than one, to rule out some OS/video driver issue. You could also try changing video card driver. If your motherboard has an integrated video card you might try disabling the external one.
Also check that the computer doesn't overheat after being on for a while. Maybe it's full of dust? |

Alas I have only one OS now and one card. I've updated the driver, there was a newer one. Didn't change a thing. It isn't heat related. If anything it gets better over time, as long as something is happening on the screen, may it be me typing and clicking or a movie playing.
CODE Maybe it's full of dust? Certainly not! Really! I think you can see the pattern och colors shifts I get on this mobile picture. I can see it when I look at it on my phone, even if smoothed out a bit. Obviously I don't know how it fares on a computer screen. Look at the browser chrome and the light-blue forum menus. I couldn't upload it. Guess it's too large and I don't want to downsize it so here goes. https://s24.postimg.org/v2eb2u11x/screen.jpg |

Obviously I don't know how it fares an a computer screen. Look at the browser chrome and the light-blue forum menus. Yes I can see greenish distortions on the Windows menus. That looks like a photo of the monitor screen. Do the distortions show up on screen captures too? That should determine if they come from the PC/video card or from the monitor. |

You don't see that raster pattern?
No, screen caps don't show it. I thought it always was that way. So what does that tell us? That it is the screen? That is I don't think it shows. Wait, I'll take a screen cap and you can tell me. I can't determine if what I see is in the picture or on my screen. I uploaded one to my phone and thought it looked normal, but that was a while ago when I only had the lines. |

Sounds like the screen to me (or the path to it). At least I don't think it's the video card or OS. QUOTE Wait, I'll take a screen cap and you can tell me. That one looks normal... |

You are so clever! Hmm. That's another way of saying I'm dumb, isn't it?
That's for the best, even if it's the most expensive option. As said, I was thinking of a new screen anyway. This is more than 7 years, so I guess it's time. I'll regret later that I didn't catch the after christmas sale, but my nerves are too fragile for that. Thanks! Of course, you realize that if I buy a new screen and the display still is garbled, it's all on your head, right? |

Hm, what's the path to the screen? I didn't know there was such a thing.
It's good black and white aren't affected at all. It's totally OK to write here, use my editor and so on as long as I don't let my eyes wander outside the editing area. When I go to bed and turn off the light I see this flickering pattern before my eyes before I fall asleep. Maybe I'll throw a fit or go mad or something. |

BTW, what do you think about that screens get larger and larger but most of them keep the same resolution, 1920 x 1080? What's the use of a larger screen if the pixels are "stretched out"?
There are very few screens with a higher resolution than the above that doesn't cost an arm and a leg, but I've found a few, for instance this one. It's a little pricier than I was planning on paying. http://www.elgiganten.se/product/datorer-t...k-uhd-led-skarm My first screen ever was a tiny, used NEC that had a very high resolution for that time. I've never had a sharper screen. So maybe the way to go is to choose a smaller screen. Or maybe two of them. My card allow for two screens so... |
