[SOLVED] DL-DVI support in 2019?

Hi, I have an Acer (GN246HL) monitor that doesn't have a DP, but instead uses DUAL-LINK DVI to recieve a 144HZ signal. I'm looking to build a new PC, but struggling to find graphics cards that describe support for dual-link DVI in the sub-£200 region. I would prefer to buy new (I can look into used if really necessary). Does anyone know of any decent GPUs that support dual-link DVI? I can only, at best, find cards that support regular DVI and I don't understand whether that's different to dual-link. (I was looking at rx 570s and gtx 1650s and they supported DVI, not sure if this means it will work with my monitor or not?)

Thanks in advance for any help, I don't really know what I'm doing.

Here is one.

https://www.newegg.com/msi-radeon-rx-570-rx-570-armor-mk2-8g-oc/p/N82E16814137291

Found it by searching for DL DVI cards. (from search engine, not Newegg search.) That was the first one that came up. I'm sure there are others. DVI-D is common now, DVI-I is hard to find. I'm assuming they are DL-DVI and not SL-DVI. But if newegg doesn't say I would check the manufacturers page.

Edit: Here is a 1660.

I know this is USA/Newegg. I'm sure there has to be cards in England that support this.

Oh, that confirms what I thought would be true - I have a DVI-D monitor and my current GPU (GTX 970) has a DVI-I port that supports it, so it should probably be fine running 144hz through a GPU like that one with DVI-D. Thank you for your reply!

Perhaps I'm missing something in the issue here, but why would you need DVI-I specifically? You don't need an analog signal, which is the difference between DVI-I and DVI-D. Where do you get that your monitor specifically has to use DVI-I?

It's not that I need DVI-I (I didn't write it, but my monitor is DVI-D anyway), it's that I didn't previously understand whether DVI-D on a modern graphics card would be dual-link (it doesn't seem to be specified anymore).

DVI-D doesn't mean it's DL. I'm not 100%, but I'm sure it's possible to have SL DVI-D. I would confirm with the card manufacturer that the DVI port is DL. SL ports wouldn't have the bandwith needed for 144Hz. I'm pretty sure you need DL DVI or DP for that.
