    Hi there I'm having an issue extending my display via an external monitor (Samsung 23inch). I’m using a 5750G with GT 540M and Intel HD 3000.

    I can't seem to run 2 displays at once.. like if I connect an external monitor via the VGA or the HDMI.. I can use that monitor on it's own (while the laptop screen is disabled) just fine.. but the moment I try to duplicate displays or extend my desktop across two monitors.. the intel driver crashes...

    The Intel driver keeps crashing and recovering every 2 seconds until the whole PC blue screens. (VIDEO_TDR_FAILURE - igdkmd64.sys)

    This is when windows is trying to run both monitors at once. If I quickly press Win+P and set it to a single display, it’s fine.

    I can output to the external monitor (show desktop only on 2), via both VGA and HDMI and the laptop screen is off. This works fine, even at 1080p.
    I can output to the laptop screen only (show desktop only on 1), and the external monitor is off.

    If I choose "duplicate", only the laptop screen works... But it drops down to a low res (1024x768)... In the Multiple Displays setting dropdown... “Duplicate” is no longer selected... and it’s now set to “Show desktop only on 1”. If I try change to duplicate again… both monitors go blank.

    If I try to extend these displays, the laptop screen stays on... the monitor goes blank, and the laptop screen immediately starts to flick off and on... as the driver crashes and restarts. I see the little dialog box in the notification area saying “The display driver has stopped responding and has recovered.” Specifying the Intel driver.

    So here’s what I’ve tried so far:

    Windows 8.1 fully updated, with the latest Intel Drivers and NVidia Drivers.

    Windows 7 x64 SP1 with latest Intel and NVidia drivers... as well as the old drivers that are listed on the Acer site. Each time I completely uninstalled and deleted the old drivers before installing new ones.

    I’ve tried these Intel drivers:
    8.15.10.2342 (Acer site)
    8.15.10.2622 - 15.22.54.64.2622
    9.17.10.3347 - 15.28.20.64.334s7
    9.17.10.3517 - 15.28.22.64.3517 (latest)

    I updated the BIOS (1.21). I also went into the BIOS and changed the GPU setting from ‘Switchable” to “Integrated” which basically disabled the GT 540m. I’ve googled, and there doesn’t seem to be a way to run the laptop with just the GT 540 doing everything. Even with just the Intel graphics enabled... same issue.

    I’ve tried adjusting power management settings to ensure that power is always at max.

    I know it’s not an issue with the external monitor or cables, as they all work fine when the laptop screen is not running... Also, I tested with a Samsung LCD TV with the same issue. The monitor and cables work fine with my PC and other Laptop.

    So for some reason, the Intel driver does not want to let 2 screens display at once. And the way the Optimus technology works, I don’t think I can bypass the Intel GPU and use the NVidia one alone.

    Anyone have any suggestions?

    Would it be possible to flash the BIOS via DOS?
    I am using an Linux only Acer 5755g at the moment and would like to have some UEFI features, like a gpt windows installation and so on.
    Or do i have to install Windows first to update the bios.

    I'm hoping this is not dead yet since Aeonia gave me some hope in decreasing my v3-571g-6407 temps. (w8 x64, i5-3210m and 630m 1gb vram)
    So my system came with w8 so it has an EUFI bios version 2.01, meaning I cannot use the 1.13 given here, even if I could I would need to reinstall windows given it doesn't have UEFI support and my partitions would not be recognized by windows.

    Would it be possible to mod one of the 2.X bios to decrease the vcore and lower the temps?

    EDIT: Ok I missed your post on page 5 giving a modded 2.21 bios, thanks. I already tried a different modded 2.21 with biod advanced options unlocked and seems to work using same voltages as here 0.887, it did reduced my temps but still reaches over 90 degrees, seems I need to do some cleaning.

    Hi, Can I use these BIOS files having GT730M on board? Is it compatible with every V3-571G config or does it depend on the graphic card? Because it seems I have the same problems with my GT730M setup, and I hope to solve it with these under-voltaged settings

    To answer your question, No sir you can't, each GPU has a different BIOS that runs it, flashing one that isn't specific to it will ultimately not work and cause issues as to damaging or bricking your laptop.

    Dear Ellric,

    I have the heat problems with the following laptop:

    Acer Aspire 5750G
    nvidia 630m
    Intel i5-2450M 2.5ghz (turbo boost up to 3.1 , but i don't think i use this, unless its set by default, should i used it?)
    500GB
    15.6inch 1366p
    Bios 1.15
    Laptop came with Win 7 x64 but atm i have Win 8.1 x64 installed

    Would the sollution provided above also work for my laptop or does it need adjustment?

    Sorry for my maybe noobish questions.
    I appreciate the work you do here and the people you help.
    I hope you have the time to answer my question. :)

    Sorry for the long absence guys, I have, as always, very little free time. @Neverwhere20 maybe it's too late, but it sounds like an hw issue to me. @Enlightendgamer if I remember correctly the solution you quoted above was for a 7xx family card (can't check at the moment). You can try to use one of the bioses with lowered voltage on post #1 (be sure to use the ones for GT630), trying to find the best which suits your hw. A cleaning/repaste is recommended too. Glad to see that there's still people poking around here :D

    Hello ellric.

    I have tried both of these bioses on my acer v3-571g-52454g50makk laptop, but they dont change the boost voltage on the 630m. Boost voltage is 1.1v.

    Can you help me.

    Does anyone have a mirror for the 5750G 630M (0.83-0.85) undervoltage Bios? Seems to be gone from Mega.
