Windows 8.1 Screen Tearing Intel HD4000 Graphics

I have the latest graphics driver from Intel for the HD4000 video driver and all Windows Updates applied in Windows 8.1.  I am experiencing screen tearing on my TV as a monitor when watching videos. I have tried adjusting the Intel configuration settings
for vertical sync to every permutation and the refresh rate - with no success.  Specifically, I have turned V-Sync On. This *should address the issue - but does not.  It appears the OS does not respect this driver setting. The screen tearing was
not present in Windows 8 with the same hardware.  I know that Microsoft made architectural changes to support adaptive refresh in WDDM 1.3. However I fear that the focus on enhancements for tablets' displays has been at the cost of regressions for
desktop users. I hope that since the issue is easily reproducible and occurring frequently, that someone at MS can start a ticket to work on this. Please help!

Can you rollback the
graphics driver or install a win8 driver for a test?  please also update BIOS and Chipset drivers for your machine.

    Remove all video drivers including your NVIDIA. Disconnect from internet.Get the appropriet driver for your Intel HD from here: https://downloadcenter.intel.com/ Install it and restart, then try installing the NVIDIA one. If you face any problem, it's with the NVIDIA driver.

  • Windows 8 and Boot Camp 5 with Mid-2011 iMac12,2 DISABLING INTEL HD GRAPHICS

    There seems to be some issue with this newer Boot Camp 5 and Windows 8 becuase of the Intel HD graphics in the processor. I have a maxed out Intel iMac 27" Mid-2011 with Intel Core i7 and AMD Radeon 6970M 2GB.
    When Windows 8 Pro is first installed with Boot Camp 5 USB flash drive everything seems fine. The Intel HD graphics are detected and so is the AMD Radeon. But if the machine is put to sleep the computer resumes and has a BSOD. The reason is igdkmd64.sys.
    I think the only way I know of to solve this is to disable the Intel HD graphics in Device Manager before the machine begins crashing. On "first" boot the Intel HD graphics are listed in device manager. Later depending on restart, sleep, hibernate, the Intel HD graphics are listed under hidden devices in Device Manager.
    IS ANYONE ELSE EXPERIENCING THIS?
    DOES ANYONE ELSE HAVE A SOLUTION BESIDES THIS?

    I don't know if it's just my iMac that lists the Intel HD graphics, but one day it showed up in Windows 7 and still exists today in Windows 8. Could somebody see if theirs shows up in Windows in Device Manager? Maybe with Show Hidden Devices checked.
    BTW I did a clean install and left the boot camp usb flash drive inserted during the install which automatically installs intel hd and bluetooth and then start boot camp drivers installs after Windows setup is completed.

  • Intel HD Graphics driver on Yoga 2 Pro fails after Windows 10 upgrade

    Yoga 2 Pro. Everything working fine under Windows 8.1. Upgraded to Windows 10 RTM version. Intel HD Graphics device failed, message in Device Manager is "Windows has stopped this device because it has reported problems. (Code 43)". Installed the latest Windows 10 driver for Yoga 2 Pro from the Lenovo support site (driver dated 7/15/2015). This did not fix the problem. Interestingly, the first time I installed the driver from the support site (I tried it twice), I received a message stating "I already have a newer version of the driver installed". I chose to overwrite/install anyhow, as this was the supported driver from Lenovo. In addition, the Intel Graphics Control Panel (that installed with the driver) fails to come up as well. Is this a known problem? Is there anything else to try? How do I determine exactly which version of Intel HD Graphics I have (there seems to be many versions listed on Intel web site).

    Update:  I've not had stability when using the Windows 8.1 driver on my Yoga 2 Pro running Windows 10.  The Intel HD Graphics Family driver shows "Working Properly" after first reverting back to the Windows 8.1 driver and the Micro-HDMI port works initially.  At some point though, I end up with the device showing disabled and I'm also having Audio issues.   I decided to upgrade the BIOS which went OK (upgraded from Kona BIOS Version 76CN31WW to Version 76CN43WW).  Then I re-installed the Windows 10 Intel HD Graphics Family driver from the Lenovo website (Version 10.18.15.2040 showing a data of 7/15/15 on the website but 6/16//15 once installed).  However, the driver shows disabled as not working properly so I'm not happy. I'll continue to consider purchasing a support option but figure it'll only reap an apology and perhaps some information confirming the problem but I expect paying for support won't result in a working Windows 10 driver any sooner.  I'm not aware how to report a problem like this to Lenovo without paying them to hear about the trouble they're causing me.Let me stop you from wasting your money.  I too had the problem you described.  What I made sure of was that once I installed that 8.1 driver, and in my case, the one dated March 2014, I went into Windows Update and disabled automatic updates.  That is where it kept getting updated for me.  That was a week ago and still have stability using the old driver. Hope this helps.  Intel needs to make a stable Windows 01 driver like yesterday. 

  • Problem installing Intel HD Graphics drivers on HP G62-234DX notebook for windows 10

    HI!I have a HP G62-234DX with intel HD Graphics with the processor Intel core i-3. the driver for my laptop is properly working well on windows 7, but aftering upgrading to windows 10, the driver on intel HD Graphics is not working well. I tried to search for the driver compatible for windows 10, but i could not find the driver from your website. the resolution of the graphics on windows 7 was 1360X738, but now the resolution is 1024X 768.So would you help me install the driver compatible with windows 10?Please help!

  • 2 External Monitors with the T430s with Intel HD4000

    I have read several multiple monitor threads but could not get a clear solution to this.
    Model: I have a T430s with Intel HD4000 graphics.
    Desired set up: 2 External Monitors + Lenovo LCD
    Problem: It seems that I can only drive one external monitor. I'd like to drive two external monitors, as I did previously with my T420.
    What I've tried: I have a dock and have tried VGA + DVI for the external monitors, as well as DVI + DVI. Neither setup has worked. It always greys out the third monitor in the Windows Display options.
    Any thoughts on how to drive two external monitors with the T430s? Clarity is appreciated. Thank you!

    If I'm reading the link you provided correctly, can I correctly assume that I CAN connect two external displays with just the W520 Laptop and NO docking station?
    I tested this today.  You can connect two external displays (1 VGA, 1 DisplayPort) without a docking station.  The result is 3 independent displays - the ThinkPad LCD, the VGA monitor, and the DisplayPort monitor. 

  • Intel HD Graphics

    I had a system board upgrade as the BIOS had failed on my M92z all-in-one. Now that is solved, but I no longer have the Intel HD graphics device but just an AMD graphics device. How do I get the Intel graphics back? I don't see any entry in the BIOS to turn it on or off. The graphics now seem to be low resolution even though they seem to be running at maximum pixels. It's like when you install the operating system before you adjust the screen resolution. There seems to be no HD device in the list of devices.
    Solved!
    Go to Solution.

    or not?
    It is up to the motherboard BIOS whether or not the machine supports "dual graphics mode".  This is like in many laptops, which includes a discrete graphics upgrade (such as nVidia K1000M in Lenovo W530 machines) to go along with the built-in Intel internal graphics (like HD4000 that is automatically provided on Intel CPU's which is also present in Lenovo W530 machines).
    If this dual available GPU's is the hardware configuration, then the BIOS will provide a Config -> Display option to describe how you want to operate.  Typically this is either (1) internal Intel graphics only, (2) discrete nVidia/AMD graphics only, or (3) some type of "dual-graphics" mode using both available GPU's intelligently.  In the case of Lenovo's W530 laptops this last dual-graphics intelligent mode is called "Optimus mode", which describes a BIOS-controlled behavior where the low-power low-heat internal Intel HD4000 graphics is used for all normal graphics situations, until/unless the need for graphics performance/horsepower increases beyond some threshold in which cases the BIOS automatically kicks in the more powerful K1000M to life.  The idea here is to conserve battery power if you're running in portable mode and you don't need any super graphics capability, but to automatically activate the higher-performing available discrete graphics capability if/when needed.  This is all controlled by the hardware/BIOS, sensing your graphics needs as you operate.
    In Optimus mode, BOTH of the GPU's will appear in Device Manager.  And there are TWO sets of graphics drivers installed, one for the Intel HD4000 graphics and a second for the nVidia K1000M chip.  Both devices appear in Device Manager because the BIOS activated both of them.  And then the BIOS Optimus technology controls which of the two GPU's is used at any moment, depending on graphics performance requirements at that moment.
    For desktop machines, typically dual graphics mode is NOT present (unless, again, supported by a BIOS option similar to what I described above for the W530 laptop). Typically the BIOS auto-senses the presence or absence of an additional discrete graphics chip.  If present, it automatically supersedes the use of any other available built-in Intel onboard CPU-based graphics capability.  Essentially this is auto-sensing equivalent of the "discrete graphics only" choice in the W530 BIOS setup option.  Without getting into the BIOS of your machine it's not known if an alternative equivalent to the "internal graphics only" choice is available as well, which would then disable the AMD graphics and revert to the internal Intel graphics.
    Inevitably, if a discrete graphics chip/card is available on a desktop machine, you either installed it yourself to get better graphics performance or it came from the vendor to provide better graphics performance.  Almost universally any discrete graphics option performance will be superior to Intel's internal HD graphics implementations, typically including additional dedicated graphics memory and faster GPU's.  That's why people use discrete graphics, even if their CPU's came with Intel built-in graphics capability.  Sure, Intel graphics will work and use lower power and generate less heat.  but it also doesn't have dedicated graphics memory, and doesn't have the high-performance specs of the discrete graphics option.
    Again, it's unlikely your desktop mobo supports "dual-graphics mode" as laptop boards typically do (at least the ones from Lenovo do support Optimus mode for their add-on NVidia chips).  I'd forget about looking for the Intel HD graphics which is in all likelihood a lesser performing graphics option than the AMD graphics which is now shown in Device Manager for your machine.  I'd work to get the correct driver installed (if it's not already installed) for your installed AMD chip, and configure it for proper high-resolution as you want (right-click on desktop and select "screen resolution").
    Presumably Lenovo provides the correct AMD driver file on the support site certified for use on your particular machine.  It is possible that the AMD site isn't providing the correct driver for your machine, although it might well work.  I'd start first with the Lenovo-provided AMD driver for your machine from the Lenovo support site, as that is guaranteed to work and provide the expected performance and available resolutions for your screen.

  • Satellite C660 - Intel HD Graphics update issue

    Hello,
    sorry for my English level, I'm French
    I have an issue without solution with my Satellite C660 (for the moment i hope!) I downloaded the software google sketchup 8, dedicated to the architecture drawing, but it doesnt work, I always have a bug message informing that it is necessary to update de drivers of the graphic card (According to google support it seems that OPENGL functions should be implemented in the drivers of my laptop)
    So I have downloaded the last available drivers for the configuration I have ( Intel HD graphics for pentium, windows 7 64 bits) ;
    the link ( french website, the one for Intel is not currently available, it is an .exe document)
    http://www.touslesdrivers.com/php/constructeurs/telechargement.php?v_code=37057&v_langue=fr
    I have tried to manually update de graphic card driver with the device manager menu (graphics card > update the drivers button> manual file.exe selection ), but at the end there is no update, I only have a very quick message informing that windows has determinated that the drivers are already updated.
    Actually there is no changes on the drivers (still the same date of the pilotes 28/07/2010 in the graphics card properties) and sketchup is still out of work
    Any suggestions?
    Thanks in advance

    Hello
    Thank you for the reply, the type of the laptop is the C660 2RG with windows 7.
    Regarding the Intel HD graphics I've tried to download it directly in Intel website but the appropriate file (name Intel HD graphics for Intel Pentium and Celeron Processors with Intel HD Graphics) is not available, when you click on itn you have a displayed screen which propose to scan you laptop in order to determinate your needs
    But even with this function you have at the end a message telling that the configuration is specifically done by the laptop builder and no action could be taken.
    To run the application Sketchup i need, the driver must support the OpenGL components (usually available in the graphics cards driver, but it seems that Toshiba configuation has been done without it)
    Thanks

  • MBP13, Intel HD3000 graphics, Thunderbolt Display flickering

    I have a early 2012 (late 2011?) MBP13 with a 2.8Ghz i7, 8GB of RAM, and the Intel HD3000 graphics. For awhile I was running it with a Samsung 24" monitor, and it was perfectly fine. However last fall I upgraded to the 27" Thunderbolt, and it now flickers to black, sometimes for a couple seconds. It will do this during normal operation (browsing, Office docs, etc.) but where it really shows up is when I play video streams, be it Netflix, Amazon, or Youtube. In other words, not narrowed down to a particular codec.
    Additionally, if I have a firewire drive connected to the display, and I'm doing heavy work off of it, i.e. iMovie editing of HD video content, the display will go black indefinitely.
    I have verified this behavior with two other HD3000 equipped laptops (both core i5 2.3Ghz models), so it's not just my laptop.
    So it's the monitor, right?
    Not exactly. I got a new base model MBP13 in today with the 2.5Ghz i5 and the Intel HD4000 graphics.
    The result? No problems, even full screen Netflix. Not a flicker.
    I'm wondering if this is a limitation of the HD3000 chipset, and I'm just out of luck, or if there's a fix available. I've also tried it under both 10.7.5 and 10.8 (all iterations).
    What's odd is that the variable is graphics chipset, however it's not just video; it occurs during anything that would be bandwidth intensive over the Thunderbolt bus.
    Thoughts?

    No one? I guess I'll give Apple a call.

  • Windows won't recognize my Intel video chipset

    Thanks for reading. I recently installed PARALLELS and have Windows XP Pro up and running. Everything I've tested works great, except for a game I tried installing.
    The game installed fine actually, but when I try to run it, I need to select my video adapter. In the pull-down menu, there are no adapters to select. Normally, that means I need to install some sort of driver (I'm a Windows user, new to OSX).
    Do I need to download a special driver? The game runs fine on my PC, btw. The game is not 'graphically intense' or 'hardware demanding,' it's an indy game called "Mr. Robot."
    Basically, Windows isn't recognizing my Intel GMA graphics set. Is there anything I can do so Windows will recognize it?

  • HD4000 graphics problems when using a very big external screen

    Hello,
    I just got a new LG 34UM95 (3440x1440) which can get connected via Thunderbolt or DVI. Screen detection and activation is working fine.
    However the screen is corrupted when moving the mouse or activating the dock animation or scrolling a window, ...
    Scenario:
    - MacBook Pro Mid 2012 (Intel HD4000),
    - MacOS X 10.9.3
    - really big external display (3440x1440) connected via Thunderbolt or DVI
    - both displays (integrated end external display) active at same time
    Problem:
    - graphic errors (framebuffer corruptions) on both screens ==> it looks like the framebuffer memory size or some DMA transfer addresses are miscalculated
    - when scaling down the external resolution to something smaller (e.g. 2560x1080) everything is working fine
    - when closing the MacBook and using the external display only the big screen works flawlessly
    ==> Could you please have a look at this and fix the framebuffer corruption?
    ==> This might also be a race condition where the HD4000 driver accesses RAM which it should not have access to and could lead to an security attack.
    Thanks,
    Maik

    I was able to use m_star's suggestion to fix this issue with my 2012 13" MBP. This is what I did to get it fixed:
    (1) Get KextBeast
    (2) Get a Hex editor like Hex Fiend
    (3) Using terminal copy AppleIntelFramebufferCapri.kext to the desktop (cp -r ./System/Library/Extensions/AppleIntelFramebufferCapri.kext ~/Desktop/)
    (4) Open ~/Desktop/AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferC apri with the Hex Editor
    (5) Search for "03 00 66 01 01 02 04 02 00 00 00 04 00 00 00 01", so you know what to change
    (6) Replace this sequence with "03 00 66 01 01 02 04 02 00 00 00 04 00 00 40 01", which is basically just the second last group
    (7) Save the file and close the hex editor
    (8) Run KextBeast which will install this kext to where it needs to go
    (9) Reboot

  • Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia 7300

    Late 2006, 24" iMac, 2.16 GHz Intel Core 2 Duo, Screen Tearing, nVidia GeForce 7300 GT
    I've been suffering with screen tearing, strange screen artifacts, etc. followed by totally unresponsive freezing machine. This problem has been happening to varying degrees for about 9 months.
    Initially, I was able to mitigate the problem with smcFanControl. Adjusting the fan speeds up helped keep the machine cool and prevent most of the problems. Recently, we had a spell of hot weather and the fans just couldn't keep up. If you're using smcFanControl, the only fan speed that will really make a difference is the CPU. The HDD and ODD fans are no where near where you need to be.
    Also, I noticed the machine was LOADED with dust when I took it apart, including the heat sink fins for the graphics card. If you have time you may want to try a thorough cleaning with compressed air before replacing the card. You just need to get through step 11 below to access what needs to be cleaned.
    Based on reading here and elsewhere, I decided to replace the graphics card. To give back to the community, I wanted to layout the procedure here.
    Where to buy the card.
    I had a tough time finding the right card. I did exhaustive web searches using every combination of Nvidia 7300 GT, etc. You really need to search by the Apple part number. The Apple part number for the 7300 is 661-4179, for the 7600 is 661-4180. I found it at We Love Macs and at dv warehouse. I paid $248 for the 7600 card. BE CAREFUL buying a "refurbished" card. At We Love Macs, "refurbished" means "pulled from a working machine." Could be a machine with as much mileage as yours and prone to the same failures as yours.
    The card is an MXM style card (generally used in laptops), with a giant heat sink and heat pipe assembly. The card can be separated from the heat assembly. If I had time, I would have tried a generic, cheaper, MXM style card.
    Dispelling some myths.
    People here and elsewhere have said that no Intel iMac graphics card can be replaced, that they're wedded to the logic board. The one on this model can be replaced, I've done it. Also, some have said you can't put a 256MB, 7600 GT in a machine that originally had a 128MB, 7300 GT. Also, not true. That's what I did to my machine and it is working fine.
    So here's the step-by-step on my take apart and replacement. This is just one user helping out others, PROCEED AT YOUR OWN RISK. This takes about 1 1/2 hours to take apart and 2 to put back together.
    1) Install the iStat widget and monitor the temperatures for a few days and record the temperatures (to be able to verify that you've completed the repair correctly later)
    2) Make a complete backup of any internal drives and make sure the backup will be bootable (use Carbon Copy Cloner)
    3) Use static safeguards, like an anti-static wrist strap.
    4) Get a pen a stack of paper envelopes to separate and label the pieces you remove.
    5) You'll need a #2 Phillips and #6, 8, 10 Torx. Most of the screws at T-8. There are 8 T-8s holding in the LCD. They are about 1 1/4" down. You'll need a long, skinny T-8 to get to them.
    6) Unplug the machine and place it on it's back on a large white sheet of paper.
    7) Remove RAM door, #2 Phillips x 2.
    8) Remove RAM.
    9) Remove 4 T-8s along bottom.
    10) Remove large rectangular plastic bezel surrounding the whole machine, tilt up being careful not to stress iSight cables. You'll need to stretch it around the RAM ejection tabs.
    11) Detach two iSight cables.
    12) Peel up black stickers at lower corners of speakers.
    13) Remove LCD screws, T-8 x 8. You'll probably drop a few, they're pretty easy to retrieve.
    14) Remove two retaining screws on right hand LCD cable. T-6 x2 Unplug cable.
    15) Remove LCD inverter cable, left.
    Start unplugging everything connected to the logic board.
    16) Unplug cable coming from right speaker. Note cable routing, it is the only one that's a little tricky. Also, note that the left one plugs in on the right and the right one plugs in on the left.
    17) Remove right speaker. T-10 Note: left and right speaker screws are different lengths.
    18) Unplug ODD blower cable.
    19) Unplug ODD temp cable and lift up tape.
    20) Unplug HDD blower cable.
    21) Unplug the HDD temp cable.
    22) Unplug the camera & mic cable.
    23) Unscrew the clamp securing the airport card (has two antenna cables going to it, labeled PCIE), T-6 x 2
    24) Unplug SATA cable.
    25) Unplug Power cable, thick black plastic harness, socket.
    26) Unplug ambient temp cable.
    27) Unscrew the bluetooth card, T-6 x2.
    28) Unplug CPU blower cable.
    29) Unplug power button cable, 2 conductor, tiny cable, bottom left.
    30) Unscrew left speaker, T-10, unplug from logic board, but just leave dangling, no need to remove cable completely.
    31) Remove logic board screws. Be careful to segregate them, they have different lengths and different thread pitches and thread types. Some are machine threads going into metal, some are coarse threads going into plastic.
    31a) Heat sink frame to case T-8 x 2
    31b) Logic board to case T-8 x 3
    31c) Screws at heat sink from arrows T-8 x 3
    31d) Logic board at bottom near RAM slot T-8 x 2
    32) Unplug ODD ribbon cable, be extremely careful. Release plastic tabs on each side to remove. Be sure it is fully and evenly seated when you put it back later.
    33) Remove logic board with attached graphics card.
    34) Unplug graphics card heat sink sensor cable at logic board end.
    35) Remove graphics card screws 2 x T-6
    36) Remove single screw from small L-bracket on heat sink 1 x T-6
    Replace graphics card.
    Reverse steps, put everything back together. Be careful not to pinch any cables when you put the logic board back in. When you put the LCD back in, if you can't get the screws to stick to the driver, use some glue stick from your kid's art supplies.
    Test everything. You've disconnected every cable in the system.
    I torture tested the machine with a space heater on it, 5 different videos of different formats playing at the same time. No problems.
    I took a lot of pictures inside the machine. As soon as I figure out a good place to post them, I'll try to add a link here.
    Good luck

    Greetings!
    I know this is in response to your post from over 2 years ago, but I was searching on Apple's site for the max RAM I can upgrade our refurbed iMac too and it brought up this post.
    Oddly enough, I've been experiencing the same screen issues and locking up on our iMac as well. I was concerned it was a bad memory module, but now I'm thinking it's the same issue you found.
    Because I bought this some 2+ years ago refurbed from Apple, I'm not surprised that could be the actual problem.
    I've pulled this thing apart once to replace the hard-drive which crashed about a year ago, so I'm not totally new at opening it up, but this process you mention sounds pretty intense...just wanted to get your second take on it based on what I've done thus far.
    Thanks again for posting this...it was an eye-opener as to what might actually be causing our issues with our trusted Mac!

    Has anyone else who has installed the Snow Leopard Graphics Update noticed a pronounced screen-tearing effect when scrolling in Safari? The first left 10% of a Safari window appear to be totally out of sync with the rest of the page.
    UPDATE: The same effect doesn't appear to happen in Firefox. Maybe it's limited to Safari?
