I'm very surprised that there's almost no discussion regarding the issue I'm about to report. I recently bought a T5300 Samsung TV, I'm from South America, so I guess here it would be considered a mid-tier TV. Upon initial setup, I noticed that the overall brightness of the screen changed depending on how bright or dark the scene was, and it did so in a gradual way (I'd say between 1/2 and 1 second). I thought this could be a "feature" of some kind, so I referred to the manual and found that there's an eco mode that could cause the TV to change its brightness depending on the lighting of the room, but that was disabled, and changing that setting didn't produce any result. I've never seen a TV behave that way and to me it was extremely notorious, distracting and annoying, so I sent it to the warranty service, where, according to them, they replaced the panel, but while testing it I noticed that the issue was still there. The technician came, saw the behavior and said that's how the TV was supposed to work and there was no failure and all they could do was raise the case to Samsung. I took the TV back home and did some further testing, and I noticed that if I plugged my PC through HDMI to the TV, then it would behave as expected with no dimming. One weird thing is that I also have a Fire TV Stick, and even though it also works with HDMI, it still dimmed the screen regardless of the streaming service I was using. I went to the store and tested other Samsung TVs and they all presented this issue, but other brands like LG didn't, even when they were in the same price range. So, I'm curious why this hasn't been reported by more people and why Samsung would force this behavior when the screen is clearly capable of not changing the brightness, just as you'd expect. If anyone has a similar model Samsung TV and wants to test this out, I'd recommend the credits section of this YouTube video, just because in there the behavior is very evident, but it basically affects any night or dark scene, to the point where white becomes gray. I'd appreciate your feedback on this.

Hi, I have an issue with my laptop screen that started today; It's very noticeable with bright colors and most noticeable in pure white. The upper third of the screen and a patch on the bottom-left side are dimmer than the rest. (See attached pic) I'm not sure what caused this, my brother said he might've put a slightly wet towel over the screen earlier when the laptop was turned off. It wasn't like soaking wet, just damp. But then if this is a case of water damage, how come the screen still functions at all? I tried 10 seconds with the hairdryer pointed at the screen, didn't want to damage the panel but that had no effects. Also pushing on it does nothing, neither does the "flex test". Anyways I would appreciate any input on this. If anyone has experienced this before and maybe has a solution to hopefully fix it, I would be very grateful. Thank you. Laptop: Acer Aspire 5 2019 - 15,6" 1080p IPS Matt Panel. (I edited the picture to match what I see irl so that's a pretty good representation of the problem, no exaggerations)

So I just bought a Blade 15 advanced and I’m loving it so far. All of a sudden the screen is doing a “breathing” effect whenever I’m in game. It gets dim for a second and then goes back to normal brightness. It does this about every 5 to 10 seconds. And it seems to only do it after about 1 to 2 hours of gaming. When I close the game and close steam it stops and acts normal. I’m not sure what’s wrong? At first I thought it might have something to do with Razer Synapse but I changed my lighting setting and it doesn’t seems to help. Also have heard of people having issues with widows automatic brightness messing things up, I’m not sure if that’s it though. I almost feel like the laptop it running low on power. But it seems like it would be bad design to make something that couldn’t handle the power needed by the components... Maybe it’s a temperature issue and after playing for awhile things start to throttle and slow down? But I don’t see how that could cause dimming.. I have the laptop plugged in and it’s almost fully charged. I’m playing GTA 5. Any and all help would be much appreciated!! Thanks9750h, rtx 2070, 240hz. 6175D7B8-6413-4845-9EF5-1A7F6A6C54C2.MOV

I bought a new LCD (UN55RU8000FXZA) for my office to play computer games on while I'm not working. It works great when it's hooked up to my PC, but I noticed a weird effect when playing games on consoles or watching any kind of television. When the scene of the game or video I'm watching goes dark, the entire TV dims way down and I can barely see anything. It's like the backlight of the TV is adjusting itself way down when it notices the scene is dark. There are zero options in the menus to fix this, and I've disabled any kind of auto contrast feature and all energy saving features are disabled, yet the problem persists.I have a copy of GTA5 for both PC and for PS4. So I decided to cut out as many variables as I could. I used the same HDMI input slot on the TV used the same HDMI cord, played the same game, didn't change a single setting on the TV. Yet, while everything looked normal on the PC version of the game, the backlight of the TV was adjusting automatically when using the PS4.I know I sound like a crazy person, saying that the dark scenes on my TV aren't as bright compared to a bright scene, but I KNOW the TV's backlight is changing brightness dynamically depending on how bright the scene is. I just need help disabling this dumb feature. Help me please!!!

Hey guys, I just got a refurbished dell 9570 as a warranty replacement from a dell 9560, and I noticed something weird, when I have something on the screen that is darker, the overall screen brightness lowers, like you tube on dark mode, dark mode discord, etc. But when I then switch to something bright, you can tell the screen overall has lost brightness, and it takes a few seconds for the brightness to come back up again. I even measured a white screen with a light meter and it varies from about 420 cd/m^2 to only 200. is there some kind of setting causing this? Thanks

Hi, Just been encountering an issue just now when launching a new application on windows 10. For some reason when I run a standard application like google chrome which doesn't require admin rights I'm still getting a dimming visual effect without the prompt. e.g " Would you to Run as administrator? " So far I've just rebooted my system and still experiencing this glitch. Any help on this issue would be great. cheeers

Ok, I've got a really weird problem that I can't seem to solve. I've checked various forums, and can't seem to find any answers. The other day, I was playing some totally legal homebrew roms in Dolphin using my Magic Joybox which I quickly found out is all sorts of broken. Buttons on the GC controller would open up random windows and other weird things (hitting down on the D-pad opened steam big picture mode, for example). See attached screenshots to see what I'm talking about. Before I closed dolphin, the controller triggered something that caused whichever of my two monitors is inactive to dim. If I click into a window on the dimmed monitor, focus will shift, that monitor will regain brightness, and the other display will dim instead. I've spent a solid 3 hours trying to figure this out, so I'm open to any suggestions. Really hoping that the answer is right in front of me and I'm just an idiot.

Sooooooo, my screen dimms when my mouse is on it but brightens when my cursor is on text or my other monitor, and it's anoying as hell! GTX 980 SC Ryzen 5 1600 some 1080p 144Hz AOC monitor Windows 10 Pro (I think) 64bit

Okay so as you probably read the title that is my problem. I had a lenovo legion y520 laptop and sold it last week, before selling it, I bought a samsung ssd and cloned my system into that ssd using samsung magician, so I would have all my files backed up to use on my new PC that I just built some days ago, I am using that drive now but with different windows license. My current build is: i5-9600k with Intel® UHD Graphics 630 R9-280X 8GB Ram 3200 HyperX MSI z390 motherboard I tried finding my intel graphics settings because I noticed a pattern from my old laptop, so basically the screen colors are sorta dimming, kinda similarly to night light from windows, I checked everything from power modes to display modes to bios, but nothing seemed to be the problem, I tried to download the display drivers that are meant for my processor and if I get lucky I maybe would solve the issue I have. But, when I tried running Intel's software and downloading the appropriate display drivers it would always display "A customized computer manufacturer driver is installed on your computer" message, as I understand it has something to do with Lenovo, but I don't get how to actually uninstall it, because I am running on my own built computer. As I understand it has something to do with the system cloning, and it probably took all the settings from my previous laptop, even though I bought a new windows 10 home license. It also had a displayed message "PCI\VEN_8086&DEV_591B&SUBSYS_39D117AA&REV_04" Your help would be much appreciated.

Basically, the whiter the picture, the dimmer the TV backlight gets. This is the complete opposite of the problem I saw in search results, where it dims in dark scenes. I've tested this by resizing browser window on google or reddit. Both, PC and cable, HDMI inputs have this issue, though it's a little less noticeable with TV because you won't have a fully white screen. Didn't test component cable input. TV model is 60PN5300, a discontinued 60" plasma. I checked every single setting everywhere, but to no avail. I also connected it directly to the outlet instead of the surge protector (if somehow it didn't get enough power) but that made no difference. No pics or vid because phone is broken

So I just finished my build (or so I thought) and the inside of the case is not as bright as I thought it would be. I have never installed case lighting and don't really know what my best options are. My build is white and black in a carbide air 540 case. What I'm looking for is 12" strips of white leds that are dimmable. I have seen the RGB strips and would prefer to get those but I don't know if they can produce quality white light. What are the best brand of dimmable 12" white led light strips? Can RGB lighting accurately produce white light? Any help is greatly appreciated, thanks!

Hey guys, DIY electrical project in mind only a bit stumped when it comes to varying intensity of LEDs. I recently purchased a 5m RGB LED strip which came with an included control circuit to change the colours and other features such as decreasing the brightness. Now since the strip only comes with one control circuit (which I am already using with part of the strip) I am quite limited when it comes to any projects I want to make with the remainder. Basically I want to construct my own control circuit that operates in the most effective and efficient way. The LEDs are common cathode so there are four leads in total: 1 for each colour (Red, Green and Blue) and one common lead as shown below. My question is what is an effective and efficient way to dim LEDs so I can have some control over the colour (as in if I can dim each colour individually and independent of one another then it would be theoretically possible to make any colour in the visible light spectrum)? So far I have brainstormed the following: [simplest method] Using a potentiometre in series with each anode lead Problem with this is the potentiometre consumes a lot of power when higher currents are applied to it and is therefore not as efficient as desired [Ghetto method] Place a switch in line with each anode lead so that each colour is either on or off Want to avoid this one as much as possible. Also only provides a maximum of 7 colours (ewww) [Not fully researched method] Using pwm (pulse width modulation) to vary the intensity of each LED. By far seems like the most reliable method only unsure how to set up the circuit [Again not fully researched] Somehow incorporating MOSFETs into the control circuit to vary LED intensity (this is similar to the one used on the control circuit that came with the strip) Any ideas on which method would be most effective and how to proceed in setting up the circuit and also what electrical components would be required? Right now I am mostly leaning towards using pwm.

So... I have this problem with my desktop where it dims the screen, which my cursor is not on. This works in some games, but in others, mostly FPS games, it just ruins the gaming experience I can be going back and forth and the screen goes up and down in brightness and it just drives me nuts, and it doesn't show the cursor on the other screen. My Rigs is two Lenovo screens, L2250p and L2251x running from a Zotac GeForce GT 630 1GB, it is a bit low, but better than the original GT 9500 512MB, which did the same thing. I'n running one monitor on DVI and the other on DVI converted to VGA(yeah I know it is bad...), because I do not own a DVI to Displayport, but that would not help as I ran it of Displayport on the old card. Can anyone help me turn this down function off? I have looked a lot of places in Windows and nVidia properties.
