Hdmi To Dvi D Cable Not Working

I would like to set up her laptop to connect via the displayport input.
Hdmi to dvi d cable not working. Hdmi is essentially a superset of dvi d and is still mostly backwards compatible with dvi. I ve also tried connecting the hdmi dvi d cable to a dvi d to displayport adapter. Nevertheless i tried using a few other highspeed hdmi cables but the monitor still says it doesn t detect any input. Her laptop has a hdmi out port.
When i do this my laptop doesn t recognize the monitor at all it doesn t turn black like it does when i use the hdmi dvi cable alone and the monitor continues to countdown the. The input mode on the monitor is set to dvi d so i don t think that is the problem. If you are attempting to connect an hdmi device to a tv with dvi connection you may need to use an hdmi to dvi conversion cable. Vga is on the other hand an analog format requiring a much more complex conversion when coming from a digital format like hdmi and there s bound to be.
Alternatively you can use an hdmi cable with an added hdmi to dvi adapter or a dvi cable with a dvi to hdmi adapter. So subsequently i thought the problem lies in the usb c to hdmi adapter so i went to purchase a few other adapter like the j5 create jca374 usb type c multi adapter as well as a mazer m usbcal330 usb c to hdmi adapter but all. They re both set up via dvi d from her surface dock and work just fine via the dvi d input. As for testing whether the cable might ve been faulty or the gpu socket i tested it with another monitor which has the same input.
I ve connected the laptop hdmi port to the monitor s dp port and there is no signal at the monitor. This allows communication between the hdmi and dvi devices.
