My mother gave me her old computers. This one is a solid processor. It's an Acer model. I purchased two GPUs (at the same cost) from EBAY – they’re Zotac GT630 Synergy Edition with 4GB of VRAM. I have two monitors. When I connect the card and plug the monitor into the DVI slot, everything appears black. If the card is in the slot but the monitor goes to the VGA port, it also shows black. Removing the card fixes the issue. Both cards work this way. Trying to install NVIDIA drivers shows “no card present,” so installation fails.
The system runs Windows 10 Home 64-bit (version 10.0, Build 19042). It uses UEFI BIOS P11-A2. The CPU is Intel Core i7-4770 at 3.40GHz with about 12GB RAM. Memory details show 11.6GB total, with 11.68GB available. The graphics card has a DAC type of Internal Device and supports full device operation.
Display settings confirm the monitor works only when connected via DVI or VGA. No driver issues reported beyond the missing card warning.
You don’t require two GPUs for two monitors. One GPU can handle up to three monitors. Connect the GPU and attach the monitor cables directly to the GPU, not the motherboard.
It seems there might be a misunderstanding. The message suggests that inserting the monitor into the card causes everything to appear black on the screen. It clarifies that the two graphics settings were the ones purchased, not that you're adding extra cards.
Many users still connect the monitor directly to the motherboard while installing the GPU. Wipe the GPU and its connectors with alcohol.
The motherboard might have a whitelist, allowing only certain GPUs to work. A BIOS update could help. The GT 630 isn't significantly faster than the HD 4600.
Your system was recommended a fix by @--SID--, should the motherboard BIOS be current?
