HDMI 2.0 to Dual-Link DVI-D with 144Hz?

[danielgdrive]

Hello forum, first time posting here since i have a problem that i really don't know how to go about:
I've made a pretty short-sightet decision and bought the "Acer G GN246HL" (24 inch) which supports 144Hz. Different sources say you gotta use the Dual Link DVI OR HDMI 1.3+ in order to display 144Hz, some say only the DL DVI-D is capable of 144Hz. My notebook only has HDMI 2.0 out.

What i've tried:

- HDMI 2.0 Cable ==> 1080p@60fps
- HDMI 2.0 to 'Dual-Link' DVI-D ==> 1080p@60fps
(online research revealed that apparently this doesn't work because HDMI is only Single-Layer and by that it would require an active signal conversion to true Dual-Layer DVI-D; what i'm wondering about then is why do they sell HDMI to 'Dual-Link' DVI-D cables then? The extra pins will never be used! There should only be Single-Layer cables! But if i'm wrong, please correct me!)
- HDMI to VGA active/passive converter ==> 1080p@60fps (slightly worse blackpoint (or "image quality") because of conversion)
-- all of the above with custom refresh rates (100Hz, 120Hz, 144Hz) on custom resolutions from 1080p down to 800x600 ==> no signal

So i literally tried every passive way to send a signal to that monitor to no real success.
My notebook is the 2017 Dell Inspiron 15 Gaming 7567 (i5 + GTX 1050) and this guy is clearly saying you should hook it up to a 144Hz display so the notebook itself is not the issue:

How can i do this? Is it possible? Will it introduce delay or noticeable worse image quality in fast paced games?

Thanks for any help! Regards, Daniel

The anticipated 144MHz is suggested as matched for HDMI 2.0 displays, and DisplayPort if it uses it. DL DVI-D is still digital and will relay and refresh with reasonable competence, and the in-total refresh rate of your monitor won't change, but the quality of what comes through your cable is also a factor. I myself use a HDMI/DVI-D cable and I have little issues with responsiveness and quality. Of course, my monitor isn't a 144, but the refresh rate is subjective to mass quality.

This is not what i'm asking for, i'm totally happy with the image quality over both the HDMI port and DVI, but my issue is getting a 144Hz signal to the monitor at all.

Yes, given they're both digital signal, it will relay your 144Hz.

Hello there,

I know this was half a year ago but I somehow ended up in the exact same situation as you with the EXACT same laptop and monitor... So did you manage to find a solution for this problem?

What I currently have in mind after extensive research is:
HDMI 2.0 to Display Port active converter -> Display Port to Dual Link DVI Adapter (hopefully something like THIS or perhaps THIS). Do you think this would work?

I absolutely love this monitor apart from this stupid port issue, so it would be such a pity if this doesn't work out... 🙁

Hopefully there is a workaround after all! :/

Hi ryandeleeuw, after some time it turned out that the sender unintentionally used the wrong model name of the monitor and it was actuall the 60Hz version of it (you can find that one via google) and i sent it back. For now i don't have a high Hz panel so i didn't dig further into this. From what i now is that daisy chaining especially active adapters is a really bad idea. Optimally use some native Dual DVI Output or a Panel with native HDMI 1.3+ support. I'm sorry but that's my 2 cents for now - definitely try out just using a normal HDMI cable and HDMI to DVI cable. - Daniel

Hi Daniel,

Thank you so much for your response. I've just decided to return the Acer monitor and instead get a ViewSonic XG2401, which has an HDMI 1.4 port (which apparently supports up to 120Hz, good enough!).

It arrives on Friday, and if it does work on 120Hz (hopefully it does) I will confirm it here for anyone who is looking for a monitor for their Dell 7567 in the future!
