2nd Monitor Very Dark On Boot Then Flickering?
Feb 25, 2012
I built a new PC about a month ago. BioStar A880GU3 and an AMD Athlon II X3 455 CPU. Also running Windows 7.
I set up two monitors and have them set to extend. Everything has been great up until about a few days ago. One morning I turned the PC on and my 2nd display was totally black. It was turned on and Windows was detecting it but I couldn't see anything. I drug a tab from Firefox over to the monitor and dropped it and the screen started flickering and eventually came on. Everything was cool for the next two days.
A few days later, it happened again. This time, I could faintly see that the screen was on just very dark because I could see the outlines of the Firefox window I drug over there. Now it happens every time I turn the PC on. It eventually stats flickering and comes on on it's own and stays on until I shut the PC off again.
I also can't even see the monitor's menu when I press the menu button on it. Does this sound like an issue somewhere in Windows, or just a failing monitor? It's a bunch of years old and was sitting in my basement for over a year until I built this new PC. I'm just curious because it worked fine for weeks after I started using it again.

Yesterday i bought new grafic card geforce GT440 after my old 9800 GT stoped functioning normaly(memory failure). So here is the problem, when I start any program or do anything the computer the computer is functioning normally, but when I turn to desktop(which has black wallpaper) the monitor goes so dark that I can't see almost nothing. I tryed to find some power saving options in windows(win 7 pro, 64 bit) and on envidia control panel but i cannot find any cause for that dark screen. Even if I load a black page on my mozilla the monitor goes dark. As it cannot represent dark colors normally.

I have always used an external monitor when using windows vista and now that i have upgraded to windows 7 when i plug in my external monitor it flashes on and off. I have changed the refresh rate on the monitor and all it does is change how fast the external monitor flashes. Also, I had this problem when using windows vista and I changed a setting in windows task scheduler and it fixed it. Tried doing the same thing in 7 and the problem is still there. In addition, I tried using a different monitor cable and the problem is still there.

I have a dell monitor when I installed Windows 7 on my celeron computer it seems that monitor is somehow disoriented of flickering whenever its opening up. Is this harmful to the monitor? I have an ATI built in video card. I'm just testing win 7 on this computer. I can't wait till finish buying the parts for my new computer.

I recently purchased a computer in Sept 2012 from Dino PC in the UK where I live. It has been running very well apart from an irritating red dot problem. My pc has an Intel i5 3570k processor (not over clocked) which has no additional graphics card and runs using the on board graphics HD 4000. I don't play computer games. I have connected my monitor (a Hanns G HG 216D) to another computer to check that my monitor or cables were not at fault and the lines of red dots do not appear.
I have my monitor connected to the pc with a VGA cable but I have also connected my monitor to my pc with 2 different HDMI cables and the red dots still appear. I have also connected my pc to a tv to use as a monitor with a different HDMI cable and the red dots still appear. These red dots didn't appear immediately when I first had the pc. I believe that they began to appear once I started updating my pc with the latest windows 7 updates (x64 bit).
The red dots appear horizontally across the monitor screen each time I switch on the pc at the very bottom edge of the screen (in small columns) then when the Asus screen appears (motherboard is Asus p8z77-V LX) in a single line horizontally across the middle of the screen, then again in a single line horizontally when the windows 7 start up screen appears. They then appear again if I have an image in the centre of the screen which is a dark block.
In this case they are grouped together in a horizontal block about 4 dots high and about 30 dots wide to the centre right of the dark area. The line of dots only appears horizontally and in red on dark screens. Occasionally I have seen the same lines of dots on a light coloured block in the centre right of the screen when the dots are pale blue and in the same formation. If I move the mouse over the red dots when they appear in a centre block of a dark colour the red dots momentarily disappear.

Lately my OS seems to have some kind of problem.As i'm surfing with my browser (Chrome), sometimes out of nowhere (or usually when i try to save a picture with right click>save as) the frames of another window that i have open pop-up on the screen.Like it's kinda bringing it forth but not quite.From what i've experienced this happens with my utorrent window or windows of the Windows 7 explorer.I mean not the ie browser.The one you use to explore your system files etc.Here's how it looks like.I have a dark windows background open on my Chrome, so that it's clearly visible.

On my monitor it seems like everything is too bright, as in places that should be pitch black are a bit too light. For example: on my iPod, even with full brightness settings everything looks normal, but on my PC's monitor it just doesn't look right.I calibrated color and setting gamma way low really helped, but my contrast is set to full, and my brightness is 75.The strange thing: when I ran Crysis 1, it fixed the monitor color! So I know the darn thing is capable, I just don't know how to.When I closed down Crysis it went back to normal.

when i upload a video to Internet the color and brightness turn out to be really dark-ish. i use fraps and want to directly upload my videos to Internet. when it's done uploading and processing the video turns out be extremely dark. it looks really bad without editing it but i don't want to edit because my computer won't take it anymore. should i adjust something in my monitor's colors and brightness? i have the amd vision control panel so i'll try to toggle around. i have another computer and the same version of fraps but the videos turn out to be exactly as plaid in windows media player.

I recently built a new pc and installed seven as my os. I couldn't help but automatically notice that the screen dims to darker images... I have never had this problem before with my monitor. I knew it had to be a seven feature.. Yet I can't disable it... I've tried hardware device options and power saving options... This is a stupid feature... Why would you want to Dim the screen on an already dark image....I cannot play certain games because it gets way to dark to see anything.

my laptop's screen keeps going dark after being on for only a few seconds. When the screen goes dark, I have to move my mouse around to get the screen to come back on which it usually does. After a few minutes of doing this, my screen stays on. I am running Windows 7 Ultimate 64 bit. I do have McAfee anti-virus protection. I just recently ran a virus scan which came up clear of any viruses. I also tried adjusting when the screen goes dark

Once, I saw the startup and shutdown used a black startup/shutdown with like gray or silver graphics..not the usual wimpy pale blue.
No idea how I did this--anyone else seen a different version like myself?

I have a 10 month old Acer 5820t laptop running win 7 home premium. About 6 weeks ago, the screen started going dark every few minutes and it has gotten worse. I can see the image faintly and by pressing the display brighten button can get it to come back or sometimes have to close and reopen lid it will come back. No external peripherals are connected. The Intel HD graphics card has the latest driver installed. The screen saver seems to work but the display will also go dark when the screeb saver is running.

I have installed the latest drivers, reinstalled the program, and all that jazz and the problem still persists. Pretty much when I minimize or exit from a game I play called EVE Online, my LCD remains really dark. Kind of as if someone turned down the brightness really low on the LCD. I've figured out 2 workarounds but they aren't fixes.
I simply log out and log back in and the display brightens to its usual brilliance or I hit Ctrl+Alt+Del and it has the same effect. But once I maximize the game and minimize again the screen darkens once more. Oh and in-game everything is perfect, it's only once I go to the desktop. Any ideas? I personally think its a something wrong with the refresh rate but I ahve no clue as to how to fix that.
I have attached my DxDiag results.

During the day, if we leave the computer alone, screen goes black, after a while, fans turn off. Wireless mouse wakes it up just fine. Fans startup before the screen is completely ready to go. During the night, the screen is dark, but the fans almost never stop. Why?

I am using the system spec as shown in the signature. Both monitors are connected to a single ATI 6870HD. The Dell U2311H is connected to the card via minidisplay-display port while the LG M227WD is connected via the DVI cable. The problematic monitor is the monitor over the display port (Dell). The monitor goes black randomly, sometimes during I play games. Sometimes it goes black more than few seconds, and I get a message on the screen saying power down as there is no reception from the display port.
I have updated the latest drivers, but still this problem persists. A

When I start my PC up a line of red dots appears across the monitor screen at the bottom of it. The line of dots again appears but higher up the screen when the windows screen appears. Both screens are dark in colour. Also if I have a block of dark colour anywhere with a light coloured background about 3 or 4 lines (each line directly above the other) of red dots appear across most of this block of a dark colour but none in the light coloured background. In all cases the red dots do not form a continuous line across the screen. My pc has an Intel i5 3570k processor running at 3.4GHz (not over clocked) with onboard intel HD4000 graphics. I do not have a separate graphics card.

If I let the computer sit unused, the screen goes black, as most monitors would; however, the screen stays dark when I move the mouse or hit buttons or something. Similarly, if I close the lid of my laptop when its turned on, and then open the lid, the screen stays black. Not only that, but when I closed the lid of the laptop, the computer never turned off. It was still running.I reset the power options to default as well, so there is nothing wrong there. Perhaps I should also mention that the screen successfully turns off and on in safe mode?
edit: Just tried a system restore to two weeks ago and the system crashed. Both times.

For some reason, recently, my computer has become very slow after I login. I type my password and start to login and it takes like 30 seconds to see the desktop.Is there a program out there that you would recommend that monitors all processes and applications that start (after login, not necessarily at bootup, if there is a difference)?

I recently installed Windows 7 on my laptop (far beyond the requirements). Before the installation, I was running Windows XP. I am currently attempting to play Warcraft III but the screen flickers every 15 seconds. The game has been reinstalled successfully, including appropriate updates, screen resolution, and refresh rate.
Nothing fixes the flickering and it is a little annoying. Can anyone help me out or suggest some possible solutions?

i just recently built a new gaming rig and am running an SSD for boot up.
Everything turns out just fine except when after the windows logo appears, I can hear a little crackle noise from my headphone then the monitor loses signal and my g15 keyboard LCD turns off, then a few moments later my monitor and keyboard comes back to normal and i am a the login screen. It is not a big deal but am just puzzled at why it would do this.
It does slow down my boot speed by a lot especially for an SSD. Anyone know how i can speed this up? Someone told me disable USB 3.0 to speed things up. Any problems with Asrock MOBO drivers that could affect this?

My system:
HP G62-144DX Notebook
Microsoft WIN 7 Home Premium Service Pack 1 64 Bit
Intel(R) Processor
McAfee Virus Protector (running)...
3 days ago, I started getting these 'flickering' pop ups at the top left hand corner of my screen. Some are whole ads and others are just bits and pieces like a 'puzzle'. They are non-stop and especially when I am on my AOL 'Welcome/home page'. I can hardly read what is displayed on my left screen.

I experienced some flashing/flickering/blinking of the screen while I was playing The Sims 3.I know the game has overheated graphics cards in the past, so I'm concerned; thankfully, Christmas is coming up if I need a new card.
