Hi, I am looking for a monitor that is compatible with 1.4a hdmi 120 hz. Can anyone help me, I have looked for a long time but find these are really rare.
 
Glen are you actually sure your monitors are running at 120hz over hdmi?
From the amazon page for your G2460PF:
"Max Res.: 1920 x 1080 @144Hz for DVI Dual Link and DP only"

And I can't find the same mention in the viewsonic's user guide, but viewsonic might not bother to mention as they're not a gaming monitor company like AOC is.

But my two concerns are, if it actually provides 144 hz through hdmi, as well does hdmi 2.0 mean compatibility with hdmi 1.4a?

With the HDMI 1.4a port your laptop has, you can get 144 Hz on 1080p resolution just fine, provided that your GPU can actually output 144 FPS or more.
Full list here (scroll down a bit to the 2nd spreadsheet): https://en.wikipedia.org/wiki/HDMI#Version_comparison

Also, HDMI 2.0 monitors are compatible with older HDMI 1.x ports. What sets HDMI 2.0 monitor apart from HDMI 1.4 monitor is that HDMI 2.0 monitor accepts higher bandwidth required with HDMI 2.0.

Is HDMI 2.0 backwards compatible with HDMI 1.x?
Yes, all HDMI versions are fully backward compatible with all previous versions.

Just as Aeacus says. Backwards compatible so no need to worry about that. And if you are worried about the monitor being 144 instead of 120 usually 144hz monitors (or anything above a 60hz monitor) will have the ability to switch to the lower refresh rates for vsync purposes. About the only issue you would run into is whether or not you are using a cable that is compatible with 1.4a or newer. Using an older cable that supports lesser will bottleneck what refresh rate and resolution you can display to a monitor.
 
XG2401, XG2402, C24FG70, C24FG73, NX-VUE24A, G2460PF are the monitors I know of that can support 120+ Hz over HDMI.

Just FYI to other repliers, please DO NOT go around telling people "any monitor with HDMI 1.4 will support up to 144 Hz". This is not true. Most 144 Hz monitors with HDMI 1.4 are limited to 60 Hz over HDMI.

I didn't say that any monitor with HDMI 1.4 will do. What i said was:
"Any monitor that has HDMI 1.4a or newer, with resolution of 1080p and 144 Hz refresh rate will do"
 


Exactly... That isn't true...

Did some further reading and it turns out that HDMI 1.4b doesn't support 120 Hz on 1080p with 2D processing (e.g regular gaming) while it does support 120 Hz on 1080p with 3D processing (e.g 3D glasses).

There's more to it than that, though, and HDMI 1.4b simultaneously supports and does not support 1920x1080 at 120Hz. It supports the 120Hz 1080p throughput only for 3D processing, which it does by cloning the data packet for concurrent output to the display device. For 2D viewing – which is what almost all gamers mean when they want “120Hz” – HDMI 1.4b is stuck at just 60Hz for 1080p. This is commonly misunderstood in the HDMI 1.4b spec language.

@ OP
With that new info, i don't suggest getting 144 Hz 1080p monitor for you if you're only using your HDMI 1.4b port. Instead, save some money and get 60 Hz 1080p monitor, e.g
Acer R240HY 23.8", amazon: https://www.amazon.com/dp/B0148NNKTC/
Acer H277H 27", amazon: https://www.amazon.com/dp/B0148NNKU6
 


Not at all. The GN article is wrong too. It's much more simple than that, the extra bandwidth of HDMI 1.3/1.4 is optional. Some monitors support it, some don't. There's no way to tell which is which just by knowing the HDMI version.

I have two HDMI 1.4 monitors that can do standard 120+ Hz video over HDMI just fine (XG2401, G2460PF), but there are other monitors like the VG248QE and XL2411Z which have HDMI 1.4 but are limited to 60 Hz.

The HDMI version is basically irrelevant, you can't tell whether the monitor supports 120 Hz over HDMI from that.

Yes. You need to set a custom resolution for the option to appear, but it works just fine. 144 Hz only works over DVI/DP, but the HDMI port goes up to 120.

The Viewsonic worked at 144 Hz over HDMI out of the box.

Thank you, there is wide spread misunderstanding, where people will say any monitor will do, plus companies are not clear if their monitor can or cannot handle it, Lastly, next time I will be sure to not buy a laptop that only supports hdmi :(
