Question 144hz 1920x1080p with HDMI

[Coleto]

I have a question, my laptop has got a 2.0 HDMI and I want to buy a 144hz monitor, accurately the Viewsonic XG240and I just wanted to know if I connect the laptop with the monitor with a HDMI 2.0 cable, will I get the 1080p 144hz?

My laptop is a HP-Pavilion 15-bc405ns

Is that Viewsonic XG240R? Couldn't find only XG240.

Between specs and manual, whoever typed documentation for Viewsonic made a mess of it. Specs say Hdmi 1.4 144Hz and manual says Hdmi 2 144Hz. Id say it's the latter and if your laptop has Hdmi 2 and this is the monitor you're looking at you should have no problem. Hdmi 1.4 is capable of 120Hz.

XG2401, I'm sorry, technically it should be able, no?

I checked 2401 before the 240 actually and that too supports 144Hz over hdmi.

Sorry 120Hz, https://www.viewsonic.com/au/products/lcd/XG2401.php#

XG2402 would be better, that does 144Hz over Hdmi.

Thank you for your help, but then, I found a thread (https://forums.tomshardware.com/threads/how-to-connect-to-a-120-hz-display.3268285/ ) where it shows in part 7.1 that the xg2401 can have 144hz with hdmi

Also, I talked to the HP Support and they told me that I won't get those 144hz bc my laptop is capped at 60hz, is that right?

Yeah you're probably right. Xg2401's specs and manual suggests 120Hz over Hdmi but seeing discrepancies with hdmi version between website specs and manual it's hard to know what to make of it. It's confusing and poor professionalism from Viewsonic's documentation. I trust Glenwing so go by his guidance.

Get back to them again with monitor in-mind and link them to Glenwing's guide, perhaps HP tech staff will learn something.

Hdmi Hz is not limited by the source but rather if the display allows it which is explained in Glenwing's guide.

So, with my HP Pavilion 15BC connecting the XG2401 with hdmi will I get 144hz?

There's no reason i can think of why it shouldn't work but for an second opinion @Glenwing may help further.
