Yes they are dual monitor cards. HDMI uses the same signal as DVI in a different connect (plus it adds audio support). An HDMI-> DVI adapter is just a pin converter nothing more. So yes a DVI + HDMI card will drive two DVI monitors without a problem, or two HDMI monitors for that matter.
Does DVI and HDMI work together?
The HDMI interface is electrically identical and compatible with the video-only DVI interface, which came first. For example, if a cable box or PC has DVI out, but the TV or monitor only has HDMI in, a DVI-to-HDMI adapter cable is used to connect the video.
How do I connect 2 monitors to my laptop with DVI and HDMI?
Connect the USB C docking station to your laptop’s USB C port. Now, take a DVI or VGA cable from an external monitor and plug it in the docking station’s desired port. This will connect the laptop and one external monitor together. Now, connect the laptop to a second external monitor using an HDMI cable directly.
Can you have one monitor HDMI and one DVI?
Adapters and ‘mix-and-match’ cables For example, you can connect a monitor that only has a DVI port to a computer that only has an HDMI port. In this case, the cable has one end with a DVI connection and the other end with an HDMI port.
Can you use HDMI DVI and DisplayPort at the same time?
You can freely combine HDMI, DisplayPort, and DVI. One monitor can be HDMI, the other DisplayPort and so forth. Video connections are one thing, but remember your extra monitors won’t run themselves. Each requires a power connection, obviously.
