cable needed for 144hz

[scott]

hello, I just today bought the gigabyte gtx 1070 g1 gaming edition, and I noticed it supports dual link dvi-d, hdmi-2.0b up to 60 hz on 4096x2160 res., and display port 1.4 at 60 hz on 7680x4320. I saw someone say that dual link dvi'd does not support 144hz (i have a benq xl2411z 144hz monitor) and the other two show that it only goes up to 60hz. I was informed that dvi-d only supports up to 120hz


what do i do? am I stuck only being able to do 120hz gaming or wat. pls help, i know i'm very ignorant in this matter but I'm not looking for trolls or griefers, just help.


thanks

Either use DisplayPort cable 1.3 (or later) or Dual Link DVI-D (ensure it's duel link) to support 144Hz.

Then under your Control Panel > Display > Advanced settings > Monitor Properties, set the screen refresh rate.

I was asking because the forum I was on the guy said DVI-D only supports up to 120hz. IS that true?

[Squirrell]

I think the 144 Hz means "up to 144 HZ" at the monitor's native resolution.

MY ASUS monitor is 1920x1080 natively. The manual says it can do 1920x1080 at 144Hz but only with a compatible NVIDIA-GPU graphic card via Dual-link cable connection. Also only in 2D mode (it supports Nvidia's 3D glasses.) The manual has a table of supported settings (resolutions and frequencies) for each connection type.

144 Hz also requires the cable that came with the monitor, which is due to the available frequencies being limited by the quality of the cable.

I read my monitor manual and it didn't say anything about supported graphics cards. I also couldn't find a manual for the GPU itself, so what do I do now? I plan on doing 1920x1080 on my benq xl2411z with the gigabyte gtx 1070 g1 gaming, at 144hz, but I don't know if i'm able to. From what i've read, 1920x1080 is its native resolution

Plug the cables in, restart the pc and try it. If it doesn't work, revert to hdmi.

lol what good does hdmi serve when it's only capable of 60hz?

[_I_]

dvi-d is digital only, not always dual link

HDMI is mostly for compatibility with older monitors and stuff. It's a "legacy" cable.

Over short runs, like anything commonly with a monitor, quality of the cable makes no difference. A cheap cable, like Monoprice, will perform the same as a more expensive one, well into 50'+ length

The old HDMI spec only supports 2d 1080p at 60Hz. HDMI 2.0 supports 1080p 144Hz easily. That graphics card has an HDMI 2.0 port, but I'm not sure if the monitor does.

[scott]

all I want to know is if the dvi-d dual link cable that comes with this monitor along with the graphics card I purchased are compatible, capable of pushing out 144hz on games that support it.

[Arya]

Yeah, they're compatible.

Just use nothing but DisplayPort, what else would u use?
Why do u think GPUs typically come with 3x DP on em.
144hz has to be setup in the Monitor too.
Turn off the machine, connect via DP, now power on the PC again and then with DP connected, go in the Monitor Menu and enable the highest DP spec available (1.3 or 1.4)

You just donald trump'd my question and completely ignored it. What I asked has nothing to do with display port. I was asking if the dvi-d dual that comes with my monitor is capable out outputting 144hz

To answer your question (I thought I did in the first answer, but to clarify), it depends on resolution.

Duel Link DVI-D - 1080p @ 144Hz (Pass)
Duel Link DVI-D - 1440p @ 144Hz (Fail - only goes up to 120Hz)

Understand the difference between 120Hz vs 144Hz is minor anyways. 120Hz is even and designed for V-SYNC purposes (so it matches graphics card output of 30, 60, or 120 FPS). Where as 144Hz was designed for 3D movies (films in multiples of 24 or 72 for 3D, etc). You will find most monitors actually toggle between them (depending if V-SYNC is enabled or if your using Nvidia 3D vision, etc).

---

It will come down to a bandwidth requirement:

1080p (1920x1080) resolution @ 144Hz = 8.96 bandwidth
1440p (2560x1440) resolution @ 144Hz = 15.93 bandwidth

Duel Link DVI-D = 9.9Gbps bandwidth (Pass for 1080p / Fail for 1440p)

Displayport cable version 1.0 or 1.1 = 8.64 bandwidth (Fail)
Displayport cable version 1.2 = 17.28 bandwidth (Pass both)
Displayport cable version 1.3 or 1.4 = 32.4 bandwidth (Pass both)

Your best option is getting a displayport cable 1.3 or 1.4, if you are on 1440p resolution @ 144Hz. Duel Link DVI-D can still manage at 120Hz with no major noticable difference.

If you are on 1080p (which I believe the benq xl2411z monitor is) either will do fine @ 144Hz. Just make sure it's a "Duel Link" if DVI cable (not single link), else Displayport 1.2 or better.

GTX 1070 has all the latest port revision specs (as do all GTX 1000 series GPU)
So any of those ports can do 144Hz really, just not at 2160p; but below this, no problems.

OP: here u can see even a GTX 960 has no issues pulling that 144Hz
