Hi jhonela,
Welcome to the HP Forums!
I understand that your laptop's display is blank with lines going across, and I would be happy to be of assistance!
I recommend following this document on Resolving Problems with Notebook Displays (Windows 7). In addition, please refer to this resource on Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot. This should help determine whether or not there is a power or a software issue.
Please re-post with the results of your troubleshooting, and I will diligently follow up with you!

More DIsplay Problems on HPx2301 Monitor when connected to my MacBook Pro - OSX Snow Leopard

1) HP x2301 monitor
2) OSX 10.6.8 AND OSX 10,7
3) On-Screen Message "Monitor Going to Sleep"
I previously reported that the problems with my new monitor had been fixed with a change in DVI cable.
Unfortunately the fix lasted for one day. I powered off both the monitor and macbook, came back the next day and the monitor no longer detects the power book. Same is the case with an iMac and an old mac-mini. My external older Viewsonic (connected also via the same DVI cable) has no problems.
When the monitor is connected to the macbook, the macbook detects it and acts like it has dual screens - the System Preferences>Display app shows both monitors (and allows me to change resolution of the HP. Dispite this, the Monitor cannot detect a signal from the Mac.
Looks like a defective Monitor - will be contacting HP in the morning.
Also of note is that the included Documentation describes 6 control buttons on the base of the unit, including an Auto Adjust button for the user to " Press to activate the auto adjustment feature to optimize the screen image." Unfortunately, there are only 5 control buttons - there is no Auto Adjust button.
The documentation makes no mention of OSX, although it appears that drivers for the monitor have been included in the OSX distributions.

I'm back up - now using HP to mirror laptop screen. Got replacement DVI cable from HP, plugged it in an Monitor is working (again). So I have 3 seemingly identical cables - 2 supplied by HP, and one an older one I used with a Viewsonic DVI monitor.
1) The cable that shipped with the Monitor never worked,
2) The older cable worked for one day with the HP, then stopped working on the HP monitor, but worked with the older VIewsonic monitor,
3) The replacement cable from HP that is working currently.
I believe they are all DVI-i - pins appear to be identical on all three.
So I don't think its a settings or cable type issue. I suspect that the HP may have some circuitry that makes it very persnickity when it comes to signal detection - so perhaps there's some small variation is signal quality btween cables - not sure how to check that though.
We shall see if the cable 3 works for extended period.

Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display. The image is displayed with a black bar on the right and on the bottom. And the left side of the content is not visible. I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct. I held down the option key to try to detect displays or switch to resolutions that are not normally available. When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart... The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7. The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion. I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

That card is for a PC it may not give you Startup and Option-Boot screens.
The 7950 "Mac Edition" card has a very distinctive look:

Hello to all: My iMac has developed a video display problem. It displays everything in cartoon like colors - purple, green, blue. Can this be repaired? Is there a way to output to a different monitor? Thanks in advance! isplays

Hello -
My iMac has developed a video display problem. Everything now appears in a strange, cartoonish way. Purples, greens, blues. Can this be fixed, and if so, any idea how much it might cost? Also, could I output to a seperate monitor? I plan to replace the unit , but cannot right now. Thanks!

Go to System Preferences > Universal Access > Seeing.
In the Display area, reset it to "Black on white" by clicking that checkbox.
You can also reset it by pressing Command-Option-Control-8

Monitor display problem.

Hello everyone,
I am having trouble figuring out how fit my desktop size to the size of my monitor.
Indeed, I have my MBP (Nvidia 9600GT) plugged to a 27" monitor (1080p resolution).
The problem is the "real desktop", the one I see on my original screen on my MBP, doesn't show up entirely.
Either the top menu bar is SLIGHTLY cut, or the bottom dock.
I output the display in 1920x1080, even though the samsung monitor stays in 1650x1050 for some reason.
A little help would be much appreciated!
Paul.

are you trying to mirror the display (show same things between two different monitors), or are you showing different contents on each, and having problems setting the resolution just on your MBP?
I think we need a bit more information on your setup. also what is your MBP display size?
If have the monitor set to be independent of eachother (expanded desktop) you set the MBP display resolution to its native resolution, while setting the samsung monitor to its native resolution, it should automatically set the desktop menubar on the primary display correctly... If you have it so that each display mirrors eachother (whatever is shown on one screens shows up exactly the same on the other), then it is possible depending on which monitor is set as primary monitor, that can mess with the resolution display on the secondary monitor.

HT204154 monitor display problem

I have an early 2009 24 iMac and a late 2009 27 iMac. The 27 has that common problem of the monitor going black. And staying black. Computer runs fine, but screen goes black.
The monitor of the 27 goes black. Has been black for months. So I use an external LG monitor.
Yesterday, I hooked the 27 up as an external monitor to the 24. IT WORKS FINE. So.
So. The brains of the 27 will show visual to FROM another computer. And TO another computer. But it will now show visuals on itself.
What can that be?

Wierd lines on my display and frequent lock-ups w/ and w/o display problems

When booting I sometimes get weird lines and blocks on my display (the GRAY Apple screen) and then it hangs, other times the computer will boot and run fine for 20-30 minutes and then the display goes wonkers with blocks and lines and the computer does not respond. The only way I can get it to boot is to reset the PRAM by letting it CHIME 3x and then occasionally it will boot without issue and run, while other times I still get the blocks and lines on the display.
When I am able to get it to recover and re-boot after the lock-up and display problems and occasionally the box in the middle asking me to re-boot similar to a kernel panic the OPS gives me the option to REPORT the error and here is the error for others who would know more...
Thank you in advance,
Darren

Anyone know what is causing my problems? I thought it was heat so I downloaded a CPU and FAN temperature monitor and the CPU was getting VERY HOT at first so I then ramped-up the CPU FAN SPEED to maximum - it turns out the CPU FAN was not rotating well at low speed - since then I have cleaned and checked the fans and they all work as they should and blow on high(er) when the CPU temperature is above a certain level.

S.U.
Is there a kb article or something that would illuminate what to look for in these logs, or is it a matter of learning by osmosis?
Both. I am not skilled in reading logs. It is a very technical and time consuming task for the uninitiated (me!) In scanning a log I look for the backtrace and loading dependencies. The first item in the backtrace is usually the roadblock.
Beyond that you can look at the Technical Note TN2063: Understanding and Debugging Kernel Panics

Why is netflix having display problems on my macbook pro... HDCP compliance?

Watching Netflix and all of a sudden it says "Display Problems" Make sure your monitor is HDCP Compliant and is not setup for mirror airplay??

The issue is from Safari defaulting to HTML5 vs using Silverlight like it did in Mavericks.
So the options are, if you want to use Safari goto your Netflix account, playback preferences and turn off HTML5. This will revert to Silverlight and will AirPlay fine*in Safari.
If you want to use HTML5, just leave the setting for HTML5 on in Netflix and use Chrome, Firefox, etc.
You can't currently have both Safari and HTML5 Netflix when using AirPlay. You'd think Safari would be a little bit more powerful with Apples stances on browser extensions.

Windows 7 64 bit on iMac display problems and instability

I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
Here is the post:
A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
http://discussions.apple.com/thread.jspa?messageID=11286987
Summary (my own edit steps):
1. Install Boot Camp 3.0 and upgrade to 3.1
2. Uninstall graphic drivers and run Driver Sweeper
http://www.guru3d.com/category/driversweeper/
instead of:
removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
3. Install ATI Mobility (link)
4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
(Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
http://support.amd.com/us/gpudownload/Pages/index.aspx
THESE drivers I was able to install - and here is where things changed.
THIS driver changed they way windows saw the video card in device manager.
As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
+These Steps "should" work:+
delete ATI driver manually
reinstall apple driver after that and see if that works,
otherwise try the steps above
(mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)

Problems connecting 1 monitor and 1 TV to 2gb DDR3 AMD Radeon 7570 video card.

I recently purchased an Hp h8-1360t computer with a 2gb DDR3 AMD Radeon 7570 video card and an Hp 2711 LED monitor. I am having problems connecting both the monitor (dvi) and a 50" Sony LCD TV (hdmi) with a 50' hdmi cable. When starting the computer, once the initial Win 7 boot up is finished, the monitor screen goes blank, except for the mouse pointer. When I turn on the tv and select the correct input source a normal Win 7 screen with icons appears on the tv. Only the wallpaper picture displays on the monitor and no icons. If play a dvd movie it will only show up on the tv with the sound coming from the speakers attached to the computer.
I would like to retain control of the computer using the monitor. I tried to set the monitor up as the primary display source using the monitor configuration menu,but it won't allow me to save the dvi connection as the primary display source. The documentation that came with the computer and what I was able to find on the Hp site is lacking....to say the least.
Any assistance with this problem will be greatly appreciated.
Thanks,
Tony

First I would disconnect the TV HDMI cable from the computer. That should return the PC screen to normal. May have to reboot to get normal. Then reconnect the TV HDMI and go into the screen setup routine, paying attention to which screen is supposed to display what information.

1) For a while now, intermittently the screen would go grey (or some sort of a messed up pattern of rgb pixels) and I would have to power down forcefully. The frequency of this has gone up very much in the recent weeks
2) When the machine freezes, I can still hear the music playing, and Windows continues to do whatever it was doing before
3) Recently (I'm guessing after a Windows update), I wasn't able to boot into normal mode anymore. It would show the Windows splash screen, then before the login screen appears it would just go black and freeze. Leaving it for a long time doesn't lead to recovery
4) To try and fix this, I've updated the ATI driver to the latest version, which didn't work so progressively tried every version between the11.6 and 10.3 (4?) which was the default when the machine was purchased. No luck there. I've also flashed the bios and that didn't help either
5) I can boot into safe mode, so I disabled amdkmdap using sysinternal's autoruns.exe, which meant that I can boot into normal mode, but it woud fall back onto Windows' vga driver (1400x1050 only!)
6) Now, even in the low res mode, almost daily the grey screen freezing would happen and I would have to reboot. Tapping the power button allows the shutdown dialog to come up (I'm guessing), and pressing enter would shut down the machine then.
There's an awful lot of posts on the internet regarding people having issues with ATI HD6450 and similar category cards, some of which sound similar to my case. They too experienced the freezing problem and reverting or upgrading the drivers had no effect (many even reinstalled windows completely). It sounds like though, the problem is software in origin at a guess.
On the other hand, the machine is now 3-4 years old and I could imagine that the GPU or graphics memory might have suffered wear and tear -- emailing Lenovo support took a week to get a response, the only thing they asked was whether my warranty is still active (after that it's been a complete silence) are they usually this terrible?
The last thing is, when the problem first occurred I booted using a linux live CD and it was all fine, at full resolution graphics. I haven't repeated this experiment since it takes quite a while to boot from a CD... but suggested that the hardware is intact. In fact, by messing about with the drivers I was able to boot into Windows normal mode and operate for 1-2 days, after which the grey freeze happened again. I haven't been able to get back into that since.
Here is my question: Is there a way to find out whether it's software or hardware that's at fault? If it turns out to be hardware, what are my options at replacements? The GPU is soldered onto the motherboard, so do I have to replace the whole thing? If it's a software issue, would restoring to factory default state fix this issue, given that an unknown update could cause the same issue at any time... This is the last time I will buy an AIO without removable everything.

Welcome to the Lenovo Community !
Probably a good test of the hardware is use the Linux Live CD that you used earlier. If the graphics are still good when using the Live CD then your monitor and GPU are fine.
If the hardware checks out Ok then I suspect you have a driver problem. Try using a driver cleaner to fully uninstall the ATI driver since bit and pieces left over from previous driver installs can cause problems. The link below is for a free and highly recommended utility for cleaning the system of the graphic drivers. After the clean up I would try installing the original driver that came with your system.

Display problem T520

I have a T520 4239CTO. Win 7pro. I'm having a display problem. There's a 1 cm grey line 2/3rd down the screen. The image is split--part of the top display is at the bottom. The color on the screen rotates between orange, red, blue, green, etc.
I use the Lenovo update so my drivers, etc are up to date.
How do I figure out what is wrong? I'm currently using a 9-in portable monitor so I can use the laptop on the road.
I've run some of the basic Lenovo diagnostics but it doesn't seem to find anything wrong. Perhaps I'm not using the diagnostic software correctly.
Any ideas? Thanks

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Display problem - horizontal stripes appear sometimes

I've got display problem. Horizontal stripes appear sometimes (randomly?) on movies or just desktop and stop when I change screen resolution to other and switch back to 1080p. It only happens with my iiyama xb2472hd via hdmi. Everything is fine using Windows. I've tried other monitor via hdmi and the problem doesn't occur.
Any ideas how to find source of problem?
Here is video:

My hardware:
Iiyama XB2472HD + Lenovo y580 which is using Intel HD Graphics 4000 as display device

After months of having this problem I realized that it occurs only with that monitor (Iiyama XB2472HD but probably others too) when I turn it off and than on (after some time) while Arch is still running...
Common situation: I lock the screen in KDE than turn off the display using capacitive button on the device. When I come back after few hours and turn it on the stripes appear. Switching to other screen resolution for a while makes it fix.
Could it be some synchronization problem or something like that?
Have someone any idea how to debug it ?
I believe that someone (kernel developers or Iiyama) made some bad assumptions while implementing HDMI standard...
