[@ricercar8716]

A few years ago I bought a new monitor ans it had no dead pixels. A month later, a lot o dead pixels suddenly appeared. Each time I turned on the monitor, the dead pixels were in a different place! I looked with a magnifier and each dead pixel was actually the shadow of a baby spider. After a couple of weeks, all the spiders disappeared: nothing to eat but each-other. They must have all fallen to the bottom of the case. Only -- two years later a faint smudge showed up. Over a couple of days the smudge got sharper. A dead spider had fallen against the back of the LCD panel (the thread holding it away must have dried and finally broken). So, now I have one dead pixel that doesn't move. I could probably open the monitor an clean all the spiders out -- or I might do more harm than good. Someday I'll replace the monitor and then try to clean it. If there's a contest for the most unusual monitor defect, do I win?

[@pixelsandbacon]

Yes.

[@tonyx233]

have you tried turning it on and off?

[@ricercar8716]

+Ivan Alexander How would that help dislodge a dead spider? But, yes, the defect has been there more than a year and the monitor is switched off every night. Before the spider stuck in its present position, you could cause it to wobble a bit by shaking the monitor (I was trying to get it to swing back away from the LCD panel).

[@Parkourpro55]

+Ivan Alexander lol

[@DannielGamingVideosandAviation]

looks like your monitor had a few BUGS

[@UrbusGurbus]

Interesting fact: I've had a stuck pixel that would only appear if the rest of the screen was bright and the area it was on was dark. It wasnt really a problem unless you looked at a big bright window in a game and then that super bright red pixel would appear, but if you made the entire screen black, the pixel would darken so you couldn't see it (or properly test for it)

[@weaponizedestrogen]

Burn in can actually happen with flashing too. Found that out myself. Went to a site that had an error that caused the screen to flash repeatedly in the top. When i went to my desktop, the top part started flashing as well. It fixed itself after about 30 minutes

So that's why it is called screensaver... :o

[@TheoHiggins]

+Khotta Bogard But then wouldn't the screensaver burn in instead?

[@Pandsu]

+Theo “Theodoooore” higgins Burn-in happens when a certain area of the screen never changes, as in when you display a static image on your display or on any part of your display (like the task bar on a computer, for instance). A screensavers moves all over the whole screen, refreshing each pixel enough times so nothing lingers long enough to burn into the screen

[@IkBenBenG]

+Pandsu Yo Indeed, that's why all screensavers are animated and why the DVD logo that shows up when a DVD player isn't playing anyhting moves and bounces across the screen. Many modern TVs also let notifications like 'no signal' move up and down slowly to avoid them burning in.

[@Hotobu]

LCD Light Bleed vs OLED Burn In

[@InForTheLonghaul]

My friend left cooky clicker going for 2 weeks on his S4. The cooky is now burned into the screen lol. XD

[@Trekeyus]

+HiiighAsAKite if the display is an lcd the burn in is called image persistence and in all but the worst case is completely reversible. The general rule of thumb is in order to get rid of it you need to cycle though a lot of colors fast for the length of time that the static image was displayed thus while it may be reversible depending on how long the image was displayed it might take a LONG time to reverse. you might also try truing the display off for a while as sometimes that can lessen the severity of the image persistence. oh wait you said s4 that puppy is oled in witch case the burn is permanent.

Great video. Sadly even the best of the best IPS monitors like Asus Rog Swift PG279Q have backlight bleeding. Had to change 3 times to get one that was acceptable and still not perfect. Got another one yesterday (almost 2 years after my first) and i thought it was perfect but no, on the top right there is bleeding. I dont think i will get a better one sadly. Seems all IPS monitors have this issue to a degree. Sad true!

[@WarframeCrunch]

Yeah I bought "aoc cq32g1" several weeks ago and almost everything seemed to be fine. Except for blacklight glow that isn't an big issue. But the worst is ghosting of it, man it's terrible with that. It's playable, but I still have that in mind that while moving camera in game I can't see a beautiful 144Hz and I could just buy more expensive monitor with blur reduction technology. I saw documentation that Aoc have blur reduction but it's available if you have freesync OFF, but still doesn't repair the ghosting, it's the same ghosting no matter how I set it, so what's the point of that option? It have overdrive option which on OFF, low and medium it looks the same :/, on high setting it's better but then I got weird colors when I move, I will name it color artifacts. But I don't know if it's fine or no, most of the time I play in night so I should use VA monitors, but they have the strongest Ghosting I think, IPS suffer with that too. TN have the smallest ghosting of them all but black color and contrast it poor there so I could not be satisfied with that either.

[@ogshotglass9291]

It's been 3 years since you've put that comment up. The monitor is likely "fine," so to speak, but I'm sure it was a budget monitor, which often suffer from that. What you are describing is a bad "pixel response time." That's the time it takes for a pixel to switch from one color to another. A slow response rate will cause ghosting, whereas a fast one won't.

For a while (back when I watched cable TV) I use to get this weird cluster of white pixels in one of the corners but only on 1 or 2 channels. the rest were fine and using my TV for other things seems to be perfectly fine too. There was also an older flat screen PC monitor that had a single green pixel effect in one of the upper corners that would only show up when I had transparency turned on... I think that's how it worked. Both my TV and current monitor are working fine now though.

[@patrice373]

backlight bleed is mainly due to how the backlight is made : LED light cells are distributed on the edge of a translucid piece of plexiglass, shining in its thickness, the light is diffused through the main face but brighter on the edge.

I could use some help on this subject. I have a 1440 144Hz Dell TN monitor (the S2716DG) and everything is great about it except that there's a weird ghost-looking effect that follows motion on the screen when changing from dark colors to light.

I have reduced the blacklight bleeding by pressing the bolts in the edge of the LCD TV back cover (I guess that reduced the gap between the screen and the light tubes).
