Horizontal Lines Scanning Monitor Display?
Dec 12, 2012
I have horizontal lines that scan my monitor whenever i play a game. I can see the horizontal lines only on darker colors like grey, dark-green etc. I have a Samsung E2220 display that runs at 1080p on 60hz on a vga cable (no hdmi/dvi support on it). I tried another vga cable, i tried another power cable but with the same result.I have all drivers updated (monitor and other hardware). My current PC specs are: AsRock N68-C S UCC, Phenom II x4, 4Gb DDR3, Radeon HD7770, 500gb HDD Sata3 and a power supply Sirtec 500W 80+.If I open Far Cry 3, for example, i get those horizontal lines. If i minimize the game i still get the horizontal lines if i have something dark on my display (a grey/dark-green/dark-blue website).Before the HD7770 i had a GTS 450 and had the same problems. Could it be the PSU, or the motherboard or what? I also tried a different display monitor (on the VGA) and had the same horizontal lines scaning my display monitor.

I have a Dell Monitor model # 1908fwpt and we have used it as an external for a few laptops now, and on the last two hook-ups it has constant, non-flickering white horizontal lines across the screen. The only resolution that doesn't is 1280x1024 for some reason. I have changed the cables, used both VGA and DVI, and run the self-diagnostics and updated all drivers. I have chased this issue up and down and not been able to come up with a way to fix it. The monitor is not old, it hasn't been used very much, and I really don't want to replace it...
Since its done it on a few different computers I tend to think its not a driver issue, or a cable issue... And the one resolution it works on is all stretched out and flat.

I've got a scan lines (horizontal) going up as if It's scanning a paper!?This only occurs when playing (all) games without VSYNC. Leaving VSYNC on solves the problem but I'm more used to play on higher framerate. Movements feel very slow when leaving it on (especially on FPS games). I've taken screenshots but it's not visible.Also there's something fishy going on:
Additional info:
-my graphics card is not overlocked
-Not overheating when leaving vsync off (remains below 60C)
-I'm using the official MSI drivers for my MSI GTX 560 Ti Twin Frozr OC edition (ForceWare 280.26)
-Using VGA cable with a DVI adapter for my graphics card
Here's the exact problem I've found on the internet: Getting Scan Lines in High End Gaming on GTX 560

I don't have the model on me now, but recently I worked on a Compaq Desktop computer. At random times (could be any program open), it would go to a grey screen with weird horizontal lines. I upgraded the video drivers, ran a video stress test and it went over 2 hours with no problems.
The customer just reported to me that it happened again so I am thinking that maybe it is a faulty motherboard (video built onto motherboard). What do you guys think? I didn't wanna give the customer the run around saying "Let's try 1) putting in a new video card then 2) lets try reformatting and lastly 3) lets replace the motherboard)"

I start up my computer, the bios runs as normal detecting drives etc. then it gets to "loading operating system..", from here it either stays that way or changes to a screen with horizontal blue lines and if you wait a little longer still, other colored lines appear aside these blue lines. This all happens at the top of the monitor.I have tried to restart my PC several times and the same thing happens with these lines. I have also tried changing monitors, unplugging all inputs. Nothing.

OK, just woke computer up from "sleep," and everything is working fine. A few minutes later, all of a sudden, the monitor screen is filled with colored vertical and horizontal lines...and nothing is working nor is there anything else on the screen but the lines. Manually, shut down and rebooted. Opened with options on how to continue. I chose Normal Mode. Computer and screen now working as they should for the last hour.

Since a couple of weeks I have had this really annouing problem with Flashing horizontal stripes on my second monitor, i can guarantee that these are not hardware problems, the stripes do not appear when i open a program on full screen, so basically they ONLY appear on the desktop background.
Here is a link to a video of the stripes:

When I open up in regular mode, as it is setting up I get hundreds of small lines across the monitor.They are thin lines like on notebook paper but very close together. Then within a few minn. the computer restarts. My operating system is windows vista.When I restart it in safe mode I don't get the lines and it works fine except for the programs that don't start up like sound and some of the programs I try to use.

My monitor starts OK but in a few minutes the screen is either covered by a fine mesh multi colored grid or 4 verticle bars approx. 1-1/2" wide made up of fine multi colored lines similar to those seen when I defrag but running top to bottom of the screen.

I don't know if it's drivers, or the monitor, or something different. I only see the lines when windows is running (I do not see the lines in BIOS). The lines somewhat change when I change the refresh rate, however they always come back (and they're always there no matter how small, or large the lines are - they differ).
(It is sorta like a fuzz, but they're lines moving everywhere) (If I put my desktop background as a darker gray, the lines sorta look darker purple if you pay close attention) [URL]
(the image is taken from a cell phone because I wasn't sure if the lines would show if I took a screenshot, seeing that I do not know the problem)
I have also provided an image which shows my specifications of my computer: [URL]

I have faded blackish lines moving all over the screen (kind of a fuzziness). It will gradually change as I change the monitor refresh rate,however it's always there. I have noticed, I can only see it in windows; if I'm in bios, It's not active. I can not try another monitor because I have no other monitor.

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.

the display/monitor uses the generic driver for display and it is 1024×768 or 800x600 but it looks very odd it should be bigger because my screen is bigger. I have a acer monitor but is there something I can download to fix the display size?

I have 2 displays, 1 is a TV 3 meters away hooked up to my graphics card via HDMI and the other other is obviously my PC monitor. I was hoping there would be a way to have sound exclusively on the TV while I have seperate audio on my monitor?Sorry it's a bit hard to explain. Basically I want to play a game on my PC with my headphones on while a film is playing on the TV, but if I try it atm the game shows on my monitor while the film is playing, but the sound of both is coming out of the TV.Graphics card is a HD6870, using Windows 7 x64.

The only way I could shut acer down was unpluging my computer. The moniter said "no something, I'm sorry but I forget. Is there a way with the keyboard to shut it down? I called my provider and they said it was a moniter or card problem, but it works good since i plugged it back in. I have window 7.

In Windows CP Display Settings (and in Nvidia CP) my left/main display is 1 and right is 2. In Windows CP Color Management the left is 2 and the right is 1. I would ignore this except that at least a couple applications now open on opposite displays. One is a monitor color calibration program (which also identifies them reversed) and the other a Raw Image Converter. And I don't trust that the calibration program loads the profiles separately.This happened after I reinstalled Nvidia video drivers trying to fix random bsod from firefox and IE8 - which seems to have worked.

I have an external monitor, actually a TV connected via S-Video cable coming out of the back of my video card. My TV is my second desktop. All of that is fine. The problem comes in when I log off or "switch users" (there are no other user profiles on my computer - I only log off or switch user to make sure the kids can't get on without my permission - they don't know my logon code), the TV loses the picture and goes grainy, but when I log back in, the TV does not "kick in" again. The only way to get the TV to display the second desktop after logging out or switching users seems to be to restart the computer entirely. If it reboots, it picks up the TV as second monitor again.
If you simply log in again, it does not pick up the TV as second monitor. Is this related to some setting that says the TV should only be the second monitor on the admin's account and not for "all users" or something? It is annoying to always be restarting my computer to watch a video on my TV. By the way, in all cases, the "Display" settings in control panel show the TV as the second monitor. But looking at the actual TV, all you see is a grainy screen that obviously is not being fed any clear signal.

Can't get monitor to display same resolution between 2 workspaces - Microsoft Community Copy/paste of text in OP (posted Nov 21, 2012): Ok, so here's my setup:HP EliteBook 6930p with ATI Radeon HD 3450 graphics card. Win 7 Pro 32 bit installed.I have 2 workspaces, both with docking stations.Workspace 1 (primary work site) had 24" wide (primary monitor) and 19" wide monitors.Resolutions that Windows let me set were 1920x1080 and 1440x900, respectively. These monitors were also hooked to the docking station via DVI and VGA cables, respectively.Workspace 2 had a 19" standard monitor (1280x1024, VGA, set as primary) and then I would open the laptop beside it for the dual monitor (1280x800).Today I have pulled the 19" wide from workspace 1 to replace the 19" standard at workspace 2. Windows, however, will only let me set the resolution to 1280x720 (still using VGA). Even taking off the "hide modes" option or going into the ATI Catalyst Control center to try and force it does not work. I've also tried switching between which one is primary or even making it single monitor display (on the 19" wide). 1440x900 is simply not available.

Windows 7 installed without any problems, and found all the hardware devices, but the only problem I have is that the monitor will only dislplay at 1920x1080. If you lower it , the monitor will not display a full screen. Tried all resolutions, and have the latest 191 drivers. Any ideas..

Windows 7 Home Premium - Fully updated as of today
NVIDIA GeForce 9200 - Fully updated driver to the newest one released
When I look under windows display settings or NVIDEA settings there is not an option for a second monitor any more. There used to be. Now that I got a VGA spliter, there is not. I have tried a combination of everything from direct computer to 3 different monitors, all work perfectly, but when I attached 2 monitors with the spliter, all I get is the same image on each monitor.
When I hit detect, nothing happens, both monitors are identified as #1. Have rebooted, have updated, have done just about anything I can think of. Why would windows not show a second monitor option now?? Spliter and monitors work perfectly with the laptop and second older/slower computer. But on this better computer, faster and just should be a hell of a lot better computer, I am not getting the option for a second monitor.
