[SOLVED] GN246hl 144hz

[shanyin37]

Hello. I have a GN246HL. It arrived about an hour ago. I cannot seem to get 144hz to work

I'm using it on my dad's computer. My dad's video card does not have a VGA port but his motherboard does. He has a ASUS RX 480 8 gb.

I have VGA and HDMI hooked up. Again the VGA is through my dad's motherboard. Could that be why it's not working ?? 🙁

 

[shanyin37]

I am sorry. I am just noticing the sticky.

 

[shanyin37]

Well I am not sure what to say after reading the sticky but I don't think it answers my question.

VGA doesn't support 144Hz you need DisplayPort, HDMI might work depending on the HDMI version and cable.

 

[Zizo007]

Your dad's RX480 should have display port and hdmi. Don't plug anything from the screen in the motherboard.

My monitor (GN246HL) does not seem to have a Display Port on the back. I watched a video about this monitor and the person used both HDMI and another one. I think it was VGA.

Are you plugging the HDMI that came with monitor to the RX480?
You just need one cable.

 

[shanyin37]

Yes I am plugging in the one that came with the monitor. Under display adapter properties it says 60 hz.

Is it plugged to the RX480 or motherboard?
In display adapter properties, can you select 144Hz?

 

[shanyin37]

Yes it is plugged into the video card. No I cannot select 144hz 🙁.

 

[Zizo007]

I found your issue, you need a Dual-Link DVI cable:
Connectivity consists of VGA, HDMI, and Dual-Link DVI. Only the DVI port supports 1080p up to 144Hz whereas the HDMI port is limited to 60Hz even though it theoretically has enough bandwidth for 144Hz.

 

[Zizo007]

Its an older 144Hz model that's why.

OK one last question then this should be wrapped up.

What's a dual link DVI Cable? (i am hoping my monitor came with one)

Given that it is a DVI cable will I be OK without a DVI plug in on my video card?

You will need a dual-link DVI to Displayport cable. I don't think it comes with your monitor.

Hers one for 10$ on Amazon, maybe you can find cheaper locally:

[shanyin37]

Are you sure?

 

[Zizo007]

Are you sure?

Oh wait it doesn't say dual-link.

It does 😛

"The only way to get 144 Hz on the Acer GN246HL or BenQ XL2411Z is by connecting to the monitor's DVI port with a Dual-Link DVI connection. The monitor's VGA and HDMI ports are limited to around 60 Hz at 1080p."

That won't work, refer to the sticky section 0: https://forums.tomshardware.com/threads/how-to-connect-to-a-120-hz-display.3268285/

What kind of DisplayPort adapters can I use?

Getting 1080p 144 Hz on a DP to DVI connection requires specialized adapters. You cannot use normal $10 DP to DVI adapters.​

​

You need to use a DUAL-LINK ACTIVE ADAPTER, which usually costs around $80–$100 USD.​

​

Please note, you cannot use just any "active adapter". It must be a DUAL-LINK active adapter. Not all DP to DVI active adapters are Dual-Link.​

 

[Zizo007]

Yea I know I said earlier. Well the best thing if you want 144Hz is to get a displayport monitor. Even those expensive adapters don't work according to Amazon. A user with the same monitor as you got one and it did not work.

 

[shanyin37]

There is literally a video that says you need to plug in an HDMI porn with a VGA Cable at the same time to get 144hz. That must be the source of my confusion. I thought that's what they meant by dual link DVI.

 

[shanyin37]

My mind is being messed up right now trying to find out what a dual link DVI is.

 

[Zizo007]

It won't work. Basically that 144Hz will only work with DVI GPUs. Do you have the link for the VGA+DVI?

 

[shanyin37]

What do you mean oh wait it doesn't say dual link?

So I need a dual link DVI to Display port?

Yea but from I read it doesn't work and it costs 150+$.
