GPU with only DVI-D output to monitor with HDMI/DP 1440p
I recently bought a new 1440p 144hz monitor (Acer Nitro VG270UPbmiix). I'm currently using an RX 480 which only has a DVI-D output, and the monitor only has DP and HDMI. I am intending to upgrade my GPU in a few months but in the meantime was hoping to run at 1440p (not fussed about 144hz for now, would be happy with 1440p 60hz). I am currently using a basic DVI-D > HDMI cable but it only runs at 1080p.
I bought a couple of 'active' adapters, one from Monoprice and one from Amazon, which claim to do up to 1440p but both of these just give a blank screen. I think this is because they are actually DP > DVI-D and intended to be used where you have a DP output from your GPU and only a DVI-D input on your monitor, rather than the other way around.
Does anyone know if there's a cable, adapter or other solution which might work?

I'm not sure why your DVI-D > HDMI cable isn't working, it may just be a low speed HDMI or single like DVI. Buy a better one rated for 4k and it will probably work.
The active DP adapters are going the wrong way, they convert DP from the source to the intended output.
Thanks. I have an AmazonBasics DVI-D > HDMI and checked the listing and various people are saying it supports 1440p, but for me I only get 1080p when plugging into the second HDMI port (even though I get 1440p connecting a laptop with a normal HDMI cable). When I plug it into the HDMI port listed 2.0, I don't get anything and my GPU fans suddenly spin up to 100% for some reason.
I'll try buying another DVI-D > HDMI cable which claims up to 4k and see if that helps.
For AMD cards you need to install the pixel clock patcher and restart your computer to get more than 1080p HDMI output from the DVI port.

Perfect! This worked - thank you so much!
