Trying to run 144hz with monitor connected to laptop

[mbarcellos101]

I recently purchased an Acer GN246L 144hz 1920x1080p monitor, I want to connect it to my laptop that only has hdmi, are their any dvi d to hdmi adapters that will help me achieve 144hz?
Thanks for the help

The "output" from the laptop is what'll matter. Whether you adapt/convert it to DVI-D, the output has to be capable of 144Hz.

Which laptop do you have, specifically?

Ok, while the laptop has HDMI2.0 (wit a 1050TI), the monitor's HDMI port is 1.4.... so 144Hz via HDMI-HDMI is not possible.

BUT, an HDMI 2.0 to dual link DVI adapter should be able to drive 144Hz. It's just going to be a matter of finding a quality adapter. Most are DVI to HDMI, or claim to be dual link but are actually passive single link with "fake" pins attached.

I'm not aware of any that exist (I'm sure one or two do, somewhere)..... but Google isn't turning up any results I'd be confident in recommending.

Great article Glenwing!

Not to stray off topic for this post, but I have a question....

It's stated

You cannot tell whether a monitor supports 1080p 120+ Hz over HDMI just from the HDMI version.

However, given DP is typically the 120Hz+ connection of choice....if a monitor implements HDMI 2.0 then could it not be said that, by default, it supports 120Hz+ over HDMI?

I haven't found a monitor with 2.0 support (as an input) that doesn't support the higher refresh rates.

Well, it was written main with 1080p monitors and HDMI 1.4 in mind., but technically the same applies to HDMI 2.0, and there have been cases with 4K TVs where they had "HDMI 2.0" inputs but only supported 1.4-level bandwidth (typically this went under the radar since rather than being limited to 4K 30 Hz, they would support 4K 60 Hz but only with 4:2:0 chroma subsampling, which most people don't even realize, and if they do, they don't relate it to bandwidth limitations. But that's why Rtings added a "full HDMI 2.0 bandwidth" bullet point to their 4K TV spec checklist in their reviews. I've never seen an HDMI 2.0 device limited to HDMI 1.2-level bandwidth (1080p 60 Hz), since typically 1080p displays don't use HDMI 2.0. But technically it is possible.
