60hz, 120hz, 144hz etc

CivilDrone · 5 Dec 2019 at 13:27

Afternoon
Got a BenQ XL2420B which I assume is either 120hz or 144hz depending on the model
It was a very long time ago since I had one of these and cant remember which cable is required
Is there a way to tell if HDMI is capable of outputting more than 60hz?
Failing that are all DisplayPort cables the same? able to output 120/144hz?
Someone help please

Is there a possibility of the monitor not being 120hz even though its 3d vision ready?
From what I remember 3d vision must be a minimum of 120hz
Am I wrong?

Mine is a 120hz and I think it was a dual link cable and I believe you're correct that 120hz was the 3d compatible spot.

Yup Dual Link DVI-D and I've switched to display port more recently.

Have just tried an hdmi from xbox one s, which should support 120hz but no luck
My guess it would be the panel only support Dual dvi and DP as you guys mentioned above
Thank you

That monitor most likely has HDMI 1.4 ports and HDMI2.0 is required for 1080p120Hz.

I dunno about later models but none of the XL2420 line supported 120+Hz over HDMI through the original release and the first revision - I know they did another model after that but I'm fairly sure it doesn't do high refresh on HDMI either.

Guessed as much
I remember having this monitor years ago and pretty sure it was either DP or DVI-D only
Ordered a DP 1.2, should be enough for a 120/144hz @ 1080p
Will report finding today

At least yours can use DP... I have a BenQ XL2410T and just bought a RTX 2070 super. Unfortunately the monitor only likes DVI and HDMI and the card only likes HDMI or DP!

That turned a monitor that didn't need replacing to a monitor that does need replacing!

You need Displayport 1.4 to be sure.

You can convert between Displayport and DVI.

Guys its safe to say everything working as it should
DisplayPort 1.2 cable is doing wonders
Good thing I have delided and liquid cooled 8400, inside msi trident 3 there is no cooling

1660ti is able to handle this in world of tanks on max settings (120hz)

Pretty sure even the 1.2 is good for 1080p @ 144hz
Mine runs 1080p at @120hz but thats the monitor as its revision one, exact same i had YEARS ago

That's unfortunate as its a pretty good monitor even after all these years!

Pretty sure you can't convert DP to dual link DVI which is needed for 120Hz.

Startech make them, available from the Rainforest.

Can defo convert dp to dvi, I think they are a fiver, cant go wrong at that price especially if that saves you from upgrading/changing the monitor

It's your thread mate, please come back and confirm that the £5 passive adapter supports dual-link DVI

I wish I had a dual link cable. I bought a DP cable for a £5er which did the job and I am pretty sure its 1.2

So not 120Hz then?

120 indeed!
Wot maxed out at constant 119hz with no drops

That's dual-link working then

Edit: after a bit of reading it seems some monitors can support 1080p120 over single link DVI even though it falls outside the connection spec. Nice!

For 1080p DP 1.2 or above, HDMI 1.4 or above.

For 1440p you need HDMI 2.0 or above to reach 120-144Hz or DP 1.4.
