HP Envy Dv7 Display :: Flickering Narrow Horizontal Line On Monitor
May 13, 2014
For the past several days a narrow horizontal line appears in the lower part of the screen on my Envy dv7 laptop - Windows 8, Intel i5 processor - that I purchased in Janurary 2013.The line flickers in various colors and is very annoying. I pulled up the BIOS screen and the line does not appear. I don't have another monitor to plug into, so I can't run that test. Everything else is functioning normally.

I have a ENVY DV6-7246us, just upgraded to WIndows 8.1, and yesterday the display went to sleep, and upon wake, I now have a horizontal flickering line in the top 1/3 of the screen. It is a single horizontal line that appears to wrap what ever text it runs through, around to the other side of the screen. the upgrade to windows 8.1 was completed on Monday, and the line started yesterday. The computer is stock, with a genuine copy of Windows. I runa small business, and this computer is relied upon every day.

Hi - I have an 8 month old M1530. Intermittantly I have experienced horizontal lines (multiple) that flicker.
It depends upon the angle that the screen is tilted backwards. Although I have found ways to "fix" it in the past (by opening the screen completely and then adjusting to the prefered angle),
I am now getting these lines at any angle greater than about 80 degrees. And, I can no longer fix it. Any ideas what this is? Can I fix it myself (loose cable) or do I need to call Dell.

I have a fairly new y510p (about 2 months old), haswell processor intel HD4600 onboard and GT750M (non SLI model).
When connecting latop to external monitor via VGA connection, I can see the image but it looks terrible, horizontal blue lines and flickering. I don't have any option to change the refresh rate, since Windows 8.1 identifies monitor as being 60mhz (other sources work fine on that frequency).
I've tried 2 different LCD monitors, 2 different VGA cables and get same result.
Have latest drivers.
HDMI output works fine. Yet not uncommon for me to need to give a presentation at a place with older equipment where I must connect via VGA.
Before I call support to take laptop in... any one else has encountered this problem?
Is there a way for me to force the GT750M to be used for external output? I have tried setting in NVidia control panel (default NVidia to maximum performace and Intel is still being used for projection output).

It flickers when i click something or open a folder. It also goes crazy when i put on a video.
Things i've done:
Updated drivers.
''Hold power button'' method.
Clues i have:
1. I remember back when i just got the laptop, it would always flicker in the exact same way when a charger was plugged in that was too weak (power out let too low message) and changing the charger always fixed it.
Now i still have the same charger (i have 3 hp and 1 dell chargers at home that fit my laptop) and none of them seems to be ''enough'' (60w x2 65w x1 and 120w x1).
2. Another funny thing is that when i uninstalled my Ati Radeon HD5850 drivers completely, there was no flickering, but obviously, i need to have that as i use this laptop strictly for games)
3. The screen refresh rate is 60hz and not possible to change,.
4. There is NO flickering on an external screen (tried two tvs, both didn't clicker a bit)
5. You might say it's a hardware problem, but i actually somehow got it to work without the flickering earlier tonight and stayed up all night playing and it didn't cause me any issues. It was working great.
6. Occasionally the PC will freeze (could that be a battery problem? since i currently am not using one as both mine are broken and i'm waiting for a new one to ship)
7. I have had 2 blue screens of death recently. One while installing ATI drivers and other i don't remember.

I have a M17x R3 laptop since a few years. A few weeks ago I sent it to the shop to have a SSD installed and have Win7 reinstalled (Windows Explorer kept crashing all the time and I wasnt able to format for some reason). When it got back from the shop, I realized a problem that was not there before.
There are 2 horizontal lines, one at the top and one at the bottom of my screen that keep flickering. They dont appear when I'm on the desktop or playing games, only when I have a program running (iTunes, Steam, DivX, etc) in fullscreen.
Here are my specs
Alienware M17X R3
Windows 7 64 bit
AMD Radeon HD 6870M (I also have Intel(R) HD Graphics 3000 in my display drivers. Just noticed that the version for both is 9.3.0)
6GB RAM
Dont know if it has anything to do with this, but when I got my laptop back I tried to install Cataclyst Control Center and it messed up my graphics bad, I could only run 640x480 and the only way to fix this was to uninstall CCC.

Hp Envy 6t-1000 has a green tint to the monitor. There seems to be no black color. I ran the system diagnostics and everything passes. If I tyr the color palette check it fails. I have updated the video drivers, updated the BIOS, replaced the monitor cable and run a system recovery using the disks provided by HP. All to no avail. I can attach an extrenal monitor, either HDMI or USB, and it works. Only the built in display has the green tint and lack of black palette.

I just got an HP Envy, 17 inch, and I have an HP 25 inch monitor I would like to connect to it. It has the "old style" connector which was supported on my old HP Entertainment Notebook. Not on the new one! What kind of adaptor do I need to get? I do have an HDMI port on the left side of my laptop. Do I need just a regular HDMI cable?

My hp envy can't detect the external monitor. I tried to re - install the graphic drivers (hd 4600 / Geforce 740m)...
It used to work and all of a sudden it stopped. My only assumption is that the HDMI output itself is not functioning.

I have a brand new HP Envy X2 (15-C001dx) with Windows 8.1. So far it works fine by itself. I tried connecting an external monitor to the laptop using an HDMI cable from the laptop to an LG L246WPQ display. The problem is that 10-15% of the left side of the laptop screen content does not appear on the external monitor. Missing from the external monitor is the word "Start" in the upper left corner along with roughly the 2 leftmost columns of tiles. This occurs in both "Duplicate display" or "Only display on screen 2" modes. This is using a resolution of 1680x1050 which both the laptop and the LG appear to support. Using the touch screen on the laptop I can scroll the tiles to the right and see the missing leftmost columns. The information that is displayed on the external monitor begins as far left as that monitor will display. In other words, there is no black/blank area on the left. Except for the missing information on the left side, the content of the rest of the external monitor looks fine. I updated the laptop's video driver to the latest on HP.COM. No change in behavior. I tried every option I could find on the LG OnScreenDisplay, but nothing made the display any better.

I have an HP ENVY dv6t-7300 laptop. I'd like to connect it to a 1920x2000 24" monitor. My laptop has a max screen resolution of 1366x768. A couple of questions...
1). Is an HDMI cord the best way to to connect to the monitor?
2). Will the monitor stretch the 1366 pixels to fit the 1920 pixels or will the image not fill the monitor?

When I plug in an HDMI cable to my laptop the screen freezes and a black box forms around the screen. The only thing I can see is my desktop background image. Can't do anything, system is totally frozen. When I disconnect it everything works great again. What do I need to do? I'm using a HP ENVY DV7-7250us with WIN7 (64bit) installed ...

I purchased my laptop about two years ago. A few days ago, the screen suddenly dies, and on boot, it flickers a few times with the proper display, but then goes blank. The backlight seems to remain on though. When I use an external monitor with the HDMI port, the external monitor works fine, however the laptop screen remains blank. Here's a video of what it looks like when I first boot the laptop: [URL] .....

I am having some flickering, and glitches in the display, and it seems, that it depends on the lcd position. It starts after I open the display, or sometimes after the laptop has been in use for a long time. It happened before, and the hp service replaced the lcd, saying that was a faulty one, but now, with the new one, is starting again. Is a bad replacement? I have to worry for the videocard? or motherboard? I spent 350uss on the new lcd, and I really hope is the replacement.

I own a HP dv5t-1000 LAPTOP which I bought around 3 months ago.It was running great, but now a problem in LCD screen has starts appearing.Its really hard to explain that why I have attached snaps to show what's really happening.
What happens that some time discontinuous horizontal lines appears on the lower or upper part or on the whole screen of the laptop.They become prominent when the LCD brightness is dim.
The screen become normal again when I move the laptop lid back or froth.
To double check my LCD I even tried using secondary display (A CRT monitor) and the picture appears to be fine on the monitor(I guess Graphic Card is working fine).

I have a dell Inspiron n5010 laptop and use it for personal works and photo editing as a photographer. when I watch a picture, in some specific zoom levels there are weird vertical and horizontal lines witch create many regular squares in the picture. it's not matter what software display it for me (it happens in every photo browsers I have and even in firefox) here you can see them (this picture is taken by Prntscr Button):
here you can see that little squares witch is annoying for me as a photographer! these squares goes away if i zoom in more! but some times squares are bigger like this: (same photo) as you can see it looks like some sort of distortion! and here you can see the same photo when it is displayed normally: my own guess is some sort of GPU problem!what I should do to get rid of these squares? some of my laptop specs are as follow: Dell Inspiron 15 (N5010) Laptop CPU: intel core i5 2.8
GPU: ATI Mobility Radeon HD 550v RAM: 4 gig DDR3

My Dell XPS 15z model laptop display screen is suddenly turning to noising with vertical and horizontal scattered color lines. This is happening every 15 to 30 min and when the mouse cursor is activating after automatically resuming the screen normally.

Went to Futureshop today and tested their 15" mbp display model. Changed to 9600gt and put a load on the CPU (started a bunch of apps, screensaver etc). Walked around 5-10 minutes then came back to the mbp, put brightness level to 1ow and it 'wavered, pulsed, strobed'. It was subtle but was there. It looks like most if not all the new macs have this issue.

I bought my Dell XPS 13 laptop (L321X) in December of 2012. Beginning in the middle of 2013, I began experiencing my display screen suddenly become scrambled. I am attaching a photo of what happens. I did not think anything of it at first, and honestly it would happen maybe once a month. I figured it was maybe that I had the laptop on my lap and it was getting overheated. In any event, I didn't think much of it.
Since the beginning of this year, I saw that it started doing it more frequently. Within the last month, it has been happening more and more frequently, to the point that it is disrupting my use of the laptop.
I have not yet tried connecting the laptop to an external monitor to see if the issue is with my video drive or screen. It's just difficult to attach it to an external monitor in time when the problem starts, because the scrambling goes away within 20-30 seconds.

I have a problem with the video being all messed up in my Acer laptop. I made a short video which shows the problem - basically it's a persistent blue colored lines flickering everywhere where the background is supposed to be white and stable. Needles to say it renders my laptop almost unusable.
