[SOLVED] What cable should I get? Is it even possible?

[imluckysherman]

I'm trying to run my Acer GN246HL monitor at 144hz 1080p. The monitor has a DVI and HDMI only, while my 2080 RTX only has the HDMI and DisplayPort. Is it even possible to have a 144hz since they don't both have either DVI or DP?

You can run 144hz over HDMI- you just need to make sure it's an HDMI 2.0 cable.

So I just found out that the only actual option I have is to do it through DVI. Apparently that's the only output from the monitor that has 144hz compatibility. Is there any way to do a DVI converter to a DP or HDMI plugin whilst still getting 1080p at 144hz?

I did some poking around and found that whether it works or not is VERY "monitor dependent".

This monitor can only do 144Hz with DVI and your card doesn't have it. That is very unlucky.

You can drive DVI from DP or HDMI- you can get cables that go HDMI to DVI and DP to DVI really easily (so long as it is DVI-D and not the older DVI-I, although I doubt the latter would support 144hz anyways).

I run a DVI monitor off my laptop using a HDMI to DVI cable all the time- although that is just a 60hz screen. I don't see why it won't work though.

You would need a (truly) ACTIVE DisplayPort to Dual-Link DVI adapter to achieve >120Hz.
It's specifically covered off under #0 here:

Also as stated earlier, even with an expensive active DP-DVI adapter it might not work.
Its better to to return or sell your monitor and get one with DP.

I think another user with the same monitor wasn't able to get it working. Ill find the post. The Amazon user has the same montior and it did not work with the active adapter:
