There are a few you can use,
Much older PCs will have options like AGP and PCI slots
Standard computers today will have the more common PCI and PCI-E slots
You will find that before, these were necessary for expand to higher quality video rendering hardware but newer technology allows for expansion through a USB port. They sell devices that allow you to hook up a small piece of hardware to the computer that then lets you expand to multiple monitors, and provides better hardware for better visual quality as well.
The now obsolete AGP slot was used solely for video. The current slots used for video, the large x16 PCIe connectors, can also be used for general PCIe expansion cards. Sitting in shelf above my head, I still have some PCI and ISA slot video cards: using a general-purpose expansion slot for video is the standard way, and a dedicated graphics expansion slot was a short-term abberation.
An AGP video card.
pci express or AGP
That depends on which PCI slot Standard PCI slots are used by sound cards, network adapters, USB expansion cards and some video cards Some sound cards, network adapters and Wi-Fi cards use PCI Express x1 PCI Express x16 is strictly for video
PCI Express X16 or AGP 8X..
I believe you can get PCI, PCI-X or AGP video capture cards. Each card would need the corresponding slot, such as an AGP card would require an AGP slot.
Computers include expansion slots that allow users to add new devices to their computers. A computer player, for example, may upgrade their video card to improve gaming performance. They can use an expansion slot to swap out the old video card with a new one without having to replace the motherboard. What are the advantages of having expansion slots? A computer's expansion slots can be used to install network cards. If the computer does not already have a Wi-Fi adaptor, a Wi-Fi network card can be installed. Furthermore, as newer, faster Wi-Fi standards are announced, expansion card Wi-Fi adapters can be swapped out for newer, faster cards.
It is used to add an internal Graphics card on the AGP slot
A video card is plugged into an expansion slot on the peripheral bus. The exact type of peripheral bus slot varies according to the type of motherboard used. Originally, video cards were plugged into an ISA slot. Eventually they went in PCI slots, then AGP slots, and today, PCI-Express slots. Regardless of the type of peripheral bus interface, the peripheral bus connects peripheral cards, also called expansion boards, with the system chipset.
The slot that does not typically support a display adapter is the PCI (Peripheral Component Interconnect) slot. While PCI slots can be used for various expansion cards, they are generally outdated for graphics purposes. Modern display adapters primarily utilize PCI Express (PCIe) slots, which provide higher bandwidth and better performance for graphics cards.
Although the phrasing of your question is difficult to understand I think I may have an answer.All monitors work off either the video card in the expansion slot or off the motherboard's on-board video. Both are used by the monitor but not at the same time.
