HDMI 2.0 to DVI-d. Is it possible to acheive 120hz or 144hz refresh rates.

[Angelmichael]

My laptop has a 2.0 hdmi port that i checked through the specs. Now my monitor does not support 144hz thorugh HDMI. however it does through DVI-D. now my question is. if i run an adapter where i get a HDMI 2.0 cable to a DVI-D. Will i be able to get 144hz or atleast anything more then 60?

No, that will not work.

When you convert signal A to signal B; then B can never be beyond the specifications of signal A.
Thus you will never get 144hz refresh from a 60 hz signal (it can force refreash at 144 times a second, but it is only going to get new data 60 times a second).

OP said montior does not support 144hz through HDMI (duh because HDMI has no support for that high of a refresh rate), but that (at least implies) it does do 144hz from DVI.

Regradless this is irrelevent because you cant take a 60 hz signal from HDMI and somehow magically double the refresh data to get 144hz

I see that for like 4k use ??

''These standards include support for higher resolutions and refresh rates. HDMI 1.3 or higher can also be used to output 1080p content at 144Hz. If you need a 144Hz monitor then be sure''

from the 144hz link above ??

 

[boosted1g]

The 144 link is about overclocking the monitor and it says it uses DVI port from the GPU, not HDMI.

HDMI 1.0-2.0 as port specifications can ONLY perform up to 60 hz. https://en.wikipedia.org/wiki/HDMI

Since HDMI is the source data then the source is never going to be higher than 60 hz, regardless of the capability of the desitination port (DVI or DP).
Just like you can use Dolby Pro Logic to fake surround sound, but that RCA cable inputing it will never provide anything more then 2 channel stereo.

in his case his monitor is not 144 so a mute point

But the HDMI 2.0 is not a 60hz signal. http://www.tomshardware.com/answers/id-2239654/hdmi-supports-144-hertz.html
clearly its can handle more the n60hz... as well the bandwith of the cable can be supporrted by the HDMI to push the monitor to its capacity of 144hz. So the question begs to differ is whether there is a adapter that can successfully make an hdmi 2.0 to a dual link dvi.

Yes my monitor can output 144hz however it can only do that through DP or dual link DVI. thats because the monitor does not have a 1.3 or higher HDMI port.

well I think if 2.0 is fine but you do see some on that using the lower hdmi like 1.4 ??

''Let's do some math to look at the throughput potential''

http://www.gamersnexus.net/guides/2113-hdmi-interface-questions-addressed-1080p-120hz

one thing you do notice looking at this is there not ever clear on truly supports 144 or not . just seems a lot of side stepping on firm specs on that ?

if it came down to it I would just use the dual link dvi

take like this 144hz monitor and look at its specs and see using the hdmi on it is good to 120hz and only the dvi and display port is listed for 144hz

http://www.benq.us/product/monitor/XL2411Z/specifications/

same with this asus no 144 on the hdmi ??

https://www.manualslib.com/manual/432724/Asus-Vg248qe.html?page=24#manual


that's where you need to look at your monitors specs like from that asus and see how the ports used are supported


I loked at several 144hz monitors and that asus so far is the only one that states that specs showing theres does 144hz on dvi/display port only ?

like dell page 12 give that info hdmi is 60 only then it seems only 144hz at that one resolution under display port

https://www.manualslib.com/manual/1121059/Dell-S2716dg.html?page=12#manual

sure looks like you get a 144hz monitor no matter what it may not even can fully do 144hz

ben q just leaves you hanging no info at all

http://benqimage.blob.core.windows.net/driver-temp-file/XL2411Z_UM_EN.pdf

like in that gamers nexus article hdmi 2.0 may do 144hz but not in the way you think or fully like they said on that .

 

[junkeymonkey]

wow all I put got all messed up after I clicked submit and out of order ?? sorry must of been toms site screwed it up

anyway looks like 144hz only works under one condition from them specs above anyway just better off with a plain old 60hz

 

[justin_162]

For your question, I've heard some people achieve hdmi 1.4 to dp. But your mileage may vary. But refering to Everyone else hdmi 1.4 is 100% capable of 144hz 1080p. A massive common misconception. The problem is that a lot of monitors don't allow 144hz through hdmi for some reason (idk why) but some do. One i know for sure is the ViewSonic XG2401

 

[ksturhan]

I have a Asus vg248qe monitor connected with hdmi 2.0 to dell 7567 laptop. I could increase refresh rate up to 87 Hz through Nvidia control panel. HDMI 2.0 supports 120 hz 1080p but my monitor doesnt allow when hdmi 2.0 connected. If i connect my monitor with hdmi to dvi adapter to my laptop, can i get 120 hz? Cable supports 120hz 1080p bandwith. Or should i overclock the refresh rate again manually or unofficially? and can i exceed 87 hz limit over dvi adapter system?

VG248QE does not support more than ≈200 Mpx/s over HDMI.

DVI to HDMI adapters are limited to single-link DVI only and therefore will be unable to support 144 Hz unless operating in HDMI signalling mode. The VG248QE's DVI port does not support HDMI signalling mode, so that will not work.

In regards to the other posts, I know this is an old necro thread, but just to make a few corrections:

'' Now my monitor does not support 144hz thorugh ''

Don't want to pay for a GSync or FreeSync monitor? Overclock your own!

You might have heard of overclocking your processor, graphics card, and if you’re hardcore, maybe even RAM and motherboard. But have you ever thought of overclocking your monitor? It's simple, will increase your screen's refresh rate and give you a smoother gaming experience.

This is incorrect. The HDMI Specification contains no restrictions limiting the video to 60 Hz. In fact it specifically states that any video format is allowed (which includes any arbitrary refresh rate), it's literally the first sentence of the video section of the HDMI Specification. The reason DVI to HDMI adapters do not work at high refresh rates is because single-link DVI is limited to 165 Mpx/s which is around 60 Hz at 1080p by specification, and HDMI cannot produce dual-link DVI signals without an active signal converter which no one makes.

The VG248QE and XL2411Z don't support more than ≈200 Mpx/s over HDMI. That's just a limitation of those monitors, not a limitation of the HDMI standard. Other monitors, like the XG2401, don't have any such limitation and will work at 1080p 144 Hz without any problem. HDMI 2.0 is not required for 144 Hz, and the HDMI Specification contains no restrictions about the usage of high refresh rates for 3D only or anything like that. That GamersNexus article is wrong on many counts but suffice it to say, see section 5.1 here:
