So I've been using the Seasonic VA2409-H for couple of years now, its a solid monitor enough for my need, and for about a year now I use it as secondary monitor, ususally to show a firefox tab. just now after cold booting the PC, I realise around the corner of the screen, I got this greenish vignetting with a hinted of familiar firefox interface there, just like burn (image retention) in on OLED screen. I tried to change my windows walpaper temporarily to plain white solid color, and after 30 minutes leaving it on, its sorta fading out, but still noticable, hopefully it will be gone completely. My question is, is it still posibble that modern (and cheap) IPS panel still got this image retention issue? and is it just temporarily and can be gone quickly or it can be permanent one? or can it be attributed to just lower end of IPS panel? And what the easiest way to clear the issue (like me who changing the wallpaper temporarily to solid white color)? Anyway I admitted its my fault to leave the secondary monitor at idle at full brightness when showing static firefox tab .

A bit of context here. So I got back from the hospital about an hour ago, (I am fine) my little sister had an allergic reaction and I drove her down. I had been there for several hours and it turns out I left my PC on in my rush to leave. So, my display the Gigabyte G24F2 sat there with steam open in the center of the screen (covering maybe 50% of the screen) for I am guessing 6ish hours. The desktop background cycles about every 10 minutes, but that was the only part that was changing Steam, the desktop icons and the task bar were all static. Since I need to sleep at least a little before I go to work I just shit it down and power cycled the monitor. I did not bother to check it, but now I can't sleep with the anxiety my gaming monitor might be damaged. The brightness of the display is at 70% if memory serves. Incase that helps in some way.

This morning while playing games I left my screen idle while I was on my phone for little more than 5minutes. When I returned to my game the monitor looked discolored and when on certain backgrounds showed image retention. The image was to the point where I could read text. I shut off the monitor and left it for around and hour thirty or two hours when I came back it had faded a bit but wasn't completely back to normal. I then shut if off again and now the image is gone but now new images are retaining within seconds. Even in YouTube videos I'm getting scenes on the monitor and even severe color staying where text was. After leaving it on for a short time the backlight looked like it was changing its brightness and I noticed what seemed like discoloration. Even when moving around a chrome window I would get several freezes of it on my screen within seconds. I've had this monitor since late December or early January. From what I know image retention is common on ips displays and fades in time however, my case seems abnormal and today is the first time this has happened. I'm hoping the issue will resolve itself overnight if not than I'll have to wait until Monday to call customer service. What I'm wondering is if something like this will go away if I let the display stay off or if may be a panel defect. The panel has been perfect up until this point and I haven't touched the screen or caused any physical damage to the panel.

Hello. I apologise for the somewhat hyperbolic tone but I'm kinda going this crazy with an issue and I'd really appreciate your input on this. I recently overhauled my monitor setup; I went from 2 1080p displays to a 2 display setup, one 1440p and one 4K, specifically: LG UltraGear GN800-B 1440p 144hz (connected both to my Mac Mini M1 and my gaming PC) Asus ProArt PS279 CV 4K 60Hz (connected to my Mac Mini M1 only) The trouble is that I'm noticing something extremely weird in both displays. The display don't show any specific problems in normal use, but if I do the ufo ghost test (https://www.testufo.com/ghosting), that I do on every new display I get, I seem to have some weird image retention glitches. In the test you can see there are some white lines moving very quickly (kinda appearing like they're flickering) below the UFOs, and if I do the test for a few minutes I have these lines (and the ufos) remaining as a fait trace on the screen for a while. The example I'm showing is from a previous display I sent back (I'll explain later), so please consider that the effect is MUCH FAINTER on my current displays: Sorry for the terrible pictures. So in a normal situation I'd think "Ah ok, broken display....bad luck", but I changed 4 different displays, with different characteristics, from different brands, bought from different stores and they all had this same exact issue. What are the odds of buying 4 displays (in 6 months) with the same exact problem? It's just impossible. The problem is the same on windows and macOS (tested on 2 computers) with all the cables I have. It's the same for USB-C, HDMI or Display Port input. The tracks are much fainter when I use 144hz on my LG display. The strange thing is that the displays seem to work normally in every single case scenario and I never noticed traces with any other content. It's just this ufo test that seems to put my displays in a crysis, but I'm not sure if my displays are actually broken. To recap, these are all the displays I had this problem on (all bought new in the same 6 months): - BenqPD2700U (sent back 2 of this model) - LG 27UL850W - LG Ultragear (GN800-B) - Asus ProArt PA279CV I cannot have my 5th display sent back in a short time, the stores are understandably starting to become suspicious of my buying-sending back behaviour, so I'd like to know if you experienced anything similar as I'm really starting to worry a lot; If I had a proof of some kind that this problem only shows itself during this test (for its nature) I'll feel much calmer. In general I'd just like to understand what's going on as if it wasn't for the photographic evidence I'd be starting to think I'm imagining things. Perhaps could some of you test this for mee? (leave the ufo test for about 5 minutes on) Thank you very much.

So I REALLY want to get a Lg CX Oled for my new gaming pc but i’m wary of burn in... I play games with health bars and huds A lot and can often play 6-8 hours a day Given that I work from home and have a lot of free time. i’m worried I play way too much to have an OLED. Would setting my display to go into sleep mode every 15 minutes of no activity, and using pixel refresh every couple of days prevent burn in? Or will it inevitably happen no matter what I do?

Hey everyone, So I left my computer on overnight (which I only do once in awhile when downloading something big) and so when I wake up about 6 or so hours later... my screen is "flashing" so I click into another window assuming it was the program doing it. Nope, now I have a very VERY opaque overlay of my previous screen on my monitor now! At first I wasn't worried cause my other monitor (same model as I have 3 of them) flickers sometimes and I just restart my PC to fix that so I restart annnd it's still there. Now I'm kinda panicky, cause I've never seen this, and I just assumed it was burn-in. So I did some research on it, LED monitors are extremely unlikely to actually burn-in an image, and if it does it's likely a defect. What happens is you get "Ghosting" or "Image Retention" or "Image Persistence". Pretty sure they all mean the same thing, anyways so I'm pretty sure that's what I have here... Mostly because I have done this before and it hasn't caused an issue, and secondly I have 3 of the same monitor and it only happened on one of them... Some extra info, the monitors model is VP279Q-P, and I have screensaver disabled on windows. Kinda dumb I have it turned off (gonna fix that now!) but I never expected it to be an issue, seeing as I only leave the monitor on like this for a couple hours at a time and with LEDs you'd have to leave it for a couple days like that to see an effect (usually, just not in this case apparently).| What can be done about this? I've started a Ticket with Asus support but I doubt they cover this sort of "damage" if it's even damaged at all. I've seen some videos that help "fix" burn-in like this. Edit: Actually after writing this, it's improved DRASTICALLY. The flickering on the monitor is very hard to notice now on most backgrounds, and I can only see the "burn-in" well on dark programs like Steam. It seems to be going away, I'd still like to hear advice or thoughts on this however at least for others looking for answers that experienced what I have!

A couple of months ago I decided it was time to get a new notebook. My old netbook wich has served me well since 2009 had become to slow to get anything decent done on it so I looked out for a replacement and fell in love with the Lenovo X240, which is as close as you can currently get to a perfect notebook in my eyes. Some specs of the baby: CPU: Intel Core i5 (4. Gen.) 4200U / 1.6 GHzRAM: 8G DDR3L SDRAM (1600 MHz / PC3-12800)DISK: Samsung 840 Evo (256GB)DISPLAY: 12,5 inch FullHD IPS (LP125WF2-SPB2)Ports/Interfaces/Wireless: Bluetooth 4.0, 802.11ac Intel Dual Band Wireless-AC 7260 - PCI Express M.2 Card Intel I218-V (Ethernet) 2 x USB 3.0 VGA Mini DisplayPort 4-in-1 ( SD-Card, MultiMediaCard, SDHC-Card, SDXC-Card) SmartCard Reader I also got the extended 6 cell battery which together with the internal battery gives me a productive battery liftime of 15 to 17 hours which IMO is friggin awesome. As about every device it has some minor flaws, but consider this nagging on a fairly high level. The display bezel is quite rickety, its made of pretty thin plastic and isn't really anchored so you could easily put a paper/thin cardbord behind it or even your fingernail and flex it. This is not catastrophic but if you ever have held a T3x or a T6x before which feels like you could bash in brick walls with it - this is definitly not the case with the X240. The newer lenovo models have become lighter, smaller more elegent looking but as a result feel also a lot less rigid. Anyhow back to the topic. At first I was totally amazed by the device. Also the display was pretty nice in the beginning, which I suspect is a result of the high dpi (1920x1080 on 12,5inches). A lot of people describe IPS as being a completely different experience and far superior (at least in terms of image quality) than TN panels. Over the course of several weeks, meanwhile months. The X240's IPS panel started to develop serious issues in terms of image retention/watermarking/ghosting that already has been seen in the past for instance with the Retina MacBook's. I started looking around online, to see if others had the issue too and found reports pretty quickly. The problem seems to be ongoing since the beginning of 2014 maybe earlier. Not only the X240 models but also the Yogas are affected since they use the exact same IPS panel the X240 has. Concerning the Yoga there is already a 77 pages long thread on the lenovo forums reporting those problems. Also Dell notebooks who use these LG panels seem to be affected (just google it you'll find a lot more than those two links I provided here). A number of people on the lenovo forums report to already have their 2nd, 3rd replacement panel that after a while starts developing the same ghosting again, which pretty much crushes my hope that a replacement will solve the issue for good (it might do for a couple of weeks though). Considering this, I really wish the X240 had a TN panel instead of an IPS. I'm using Samsung BX2450L monitors (dual setup) on my desktop, which do have a TN panel and I'm completely satisfied with image sharpness, colors and the angle dependency. So the few advantages in terms of color fidelity/display brightness the IPS panel *might* offer over TN don't compensate for the damage caused by the image-retention because it falsifies the color/brightness of the display completely. To give you an idea how bad the issue really is I took some pictures (I already posted and commented the pictures on the lenovo forums as well): 1st image: If you look at the dialogbox closely (which is NOT semi-transparent) you'll see how the PDF reader pages continue as brighter areas in the dialog box. Its hard to see on the photo but it will become a lot clearer on the next picture. (Click here for full size version) 2nd image: Now I resized the dialog to full screen and the issue becomes way more obvious. If you now look at the lower part of the dialog box, which is located where you could see a part of the pdf before you will see that you almost can read the text of the after image (again consider this picture was taken with a bad mobile phone camera, even the regular button captions are hard to read but you're still able to recognize the letters in the after image). The after image fades to the regular grey background where the PDF file has been covered by the smaller dialog box before. (Click here for full size version) 3rd image: another fullscreen picture of the dialog, again the dialog box is not semi-transparent. The white rectangles in the background are the after image of a previously displayed PDF document. (Click here for full size version) 4rd image: Most obviously the issue becomes when you do the "checkerboard test" (http://www.marco.org/rmbp-irtest.html), which shows catastrophic after images: (Click here for full size version) 5th image: For reference the exact same test done on my desktop monitor (Samsung SyncMaster BX2450L), which shows no effect at all: (Click here for full size version) 6th image: for the record: this is what I've been able to find about my display, you can find the model name and Number of the display in the 4th line from the bottom. (Click here for full size version) According to the lenovo forum moderators there is now a newer batch of displays available that are supposed to not show these issues. From what I read on the forum the old displays carry a SPB1 in their name, whereas the new ones should be labeled SPB2. Unfortunately my X240 already came with an SPB2 display (see image 6 above) from the factory and as you can clearly see the ghosting problem is far from being solved. To me and others having a device with a panel affected the situation is extremely disappointing. I've bought the device with 5 year extended on site warranty, so yes I could call in for a technician and most likely would get that panel exchanged. Judging from what I read on the lenovo support forums that will solve the issue for a couple of weeks at best, till the display starts to deteriorate and I have to get another service appointment again and again... So apart from the time the repeated display changes will cost I don't think it will do the hardware any good, if displays are changed on reagular basis. Notebooks nowerdays aren't constructed to be taken apart so many times. I'd totally go for a FullHD TN panel but I couldn't find any on the lenovo parts list yet it seems only the 1366x768 panels are available as TN. Another option would be to ask for a refund but then again what are the alternatives? Apple devices are totally out of the question for me (no religious-/flamewar inteded here, thats just a decision I've made for myself). I definitly need a notebook that may not be larger than 13 inches it needs to deliver road warrior battery lifetimes, and offer similar ports (especially the VGA/Sub-D - which I often have to fall back when using a projector). With Samsung, Sony and Toshiba being/going out of the notebook business and Dell being affected by the ghosting issue as well I don't see many vendors left. Asus and Acer are pretty much out because of their sub-standard quality and above average Linux compatibility issues, there doesn't seem to be anything left to choose from, which leaves me pondering what should I do now?
