Hello friends. I'm trying to install an old GeForce G405 GPU to my Veriton X4660g, but when the GPU is installed, the PC does not have any video signal neither from the GPU's vga port nor the integrated vga port. When removing the dedicated GPU, the PC gives video signal from the integrated GPU. I'm checking the bios configuration to disable the integrated GPU, but the option is greyed out. What should I do?

    Your Veriton 4660G (G meaning that it has a dedicated VGA card) came fitted oem from Acer with a VGA CARD the RADEON R7 430 2GB GDDR5.128B. 1150MHz - Acer part #: DA.43011.002 and the dedicated VGA card settings in bios should not be greyed out.

    First update the bios to the last bios version R01-B4, then power down the desktop and disconnect the desktop from the wall, then remove the CMOS battery and replace it after 30 minutes for a CMOS reset, I would also replace the bios battery with a new one, as your Veriton 4660G is 7 years old and it could be that the battery has lost its full 3.3V charge and its faulty.

    Try all that as that should make the VGA bios settings below, be able to be changed. Good luck and hope this helps you out and solves this problem.

    VGA bios settings in the Veriton 4660G desktop:

    • Video Output: > (Discrete) This item shows current output video devices.
    • Onboard Graphics Controller: (Disabled) This item indicates the status of the onboard graphic controller. Enable > this item, the motherboard will not support VGA slot. It can’t be changed when in gray and the default setting is Disabled.

    Hello Steven, thanks for your answer. The stock GPU of my Veriton X4660G is an Intel UHD 630. I already tried clearing the CMOS by removing the battery and using the "CLR CMOS" jumper in the mainboard, but the option for selecting the Video Output Device is still disabled. The bios firmware is also updated.

    Your Veriton X4660G desktop which came with the i7-8700 cpu that has the integrated Intel® UHD Graphics 630, then the Intel B360 chipset type mainboard of your desktop bios and its dedicated graphics are greyed out, you will not be able to upgrade to a dedicated gpu card as the bios is set the way that it is.

    I think that for the Veriton X4660G that came with a dedicated gpu they have a different version Intel B360 chipset type mainboard that can operate with a dedicated gpu. Contact Acer Tech Support in your country and get further advice on how to enable the dedicated gpu settings in bios and if your mainboard has that feature, as I can't advise you any further. Good luck.

    They shipped some of these models with Nvidia cards instead of the AMD. The GeForce 405 is from 2011 though, so I wouldn't have thought they'd have included them in the 2018 X4660G models. You do absolutely have to have a really low power cards for those though, there is only 250W available in the PSU, so nothing available other than what's on the PCIe slot.

    The Geforce G405 is an old GPU that I recovered from another pc. It didn't came with the Veriton. I would have to test it with another low power GPU.

    Upon further testing today, I was able to get video signal from the dedicated GPU for a brief moment before POST, the Acer logo was shown and tried to enter the bios setup, but the screen went black immediately. To be able to get that glimpse of video signal, I disabled secure boot and changed CSM Support to "Always" in the bios setup before installing the GPU. I believe that the GeForce G405 that I'm testing is just too old to be able to boot, even with the CSM Support activated to work with legacy drivers. What do you guys think about?

    Unless you are trying to run Windows 7, prior to sp1, on it, don't mess with things like CSM support or secure boot. For any newer OS you want to have the boot mode in UEFI and secure boot enabled. You also will likely want, for testing purposes, to have the boot menu enabled and fast boot and quiet boot disabled. Launch CSM then should show Never. In that environment you should be able to boot from most UEFI environments, so you have access to a lot of decent tools.

    Is there a chance your monitor doesn't handle lower resolutions? IIRC when entering the BIOS the screen is set to something like 800x600 or 1024x768 instead of the normal defaults for when the drivers are loaded.
