I got a hand me down BenQ Zowie xl2411 144Hz monitor and DP to DVI adapter. This monitor was working at 144Hz with a Nvidia 1070ti using the DP to DVI adapter.

I am running a Radeon RX 5600 XT (only have DP and HDMI ports), I plugged the monitor (monitor do not have DP connection) with the same cable he was using in my PC and I cannot get more than 60Hz.

The only option in Windows-Display settings-Advance display settings-Display adapter properties is 60Hz.

Do I have to make any changes in Adrenaline, I cannot figure out what am I missing.

Please some help. Thanks

Try it with a newer cable. Read this > https://www.hdmi.org/spec/hdmi2_1

[madridm]

I tried with HDMI and do not work neither. In the BenQ forums a tech mentioned that the monitor do not accept 144Hz by HDMI.

I dont want to spend $100 in a cable when the old cable was working perfectly with Nvidia. I think I am missing something in the settings. :(

[kingfish]

A new top of the line HDMI cable is $19 on Amazon. ..and supports 144hz. Same cable I use.

[madridm]

Do you have the same monitor? (BenQ Zowie xl2411), the HDMI port in the monitor do not support 144Hz only the DVD does, that is what the BenQ tech said.

[kingfish]

Then why are they/you calling it a 144hz monitor? Something stinks.

[kingfish]

Have you checked the monitor settings menu? 

[madridm]

Yep, you know how they are to sell anything. 

But, my only concern is why it worked in a NVidia 1070ti with the same cable and not with my 5600 XT? 

[madridm]

Yes, I checked the monitor settings, I even did a factory reset to see if that fixed it but no luck. It is not receiving 144Hz from video card.

[kingfish]

I am puzzled at that myself. Let's try to get a more knowledgeable person in here:

Thanks

Did you install the monitor drivers? https://www.benq.com/en-us/support/downloads-faq/products/zowie-e-sports-monitors/xl2411p/software-d...

[madridm]

Sadly I did and didn't fix anything, did it again now and the drivers were already installed.

I ordered an active DP to DVI Dual link adapter. lets see if that will fix it. I am guessing NVidia has something AMD is missing and no need of active dual link adapter to run 144Hz.

[colesdav]

Have you seen this?

https://zowie.benq.com/en-us/support/faqlist/troubleshooting/faq049.html

Why can’t I set the frequency to 144Hz on my XL2411/XL2411P?

Please check the following:
1) Make sure your graphics card has a DVI port and a DVI Dual Link cable is used.
2) Make sure the BenQ bundled DVI cable is used.

Note: Only DVI Dual Link supports 144Hz on the XL2411.

Both DVI Dual Link and DisplayPort 1.2 support 144Hz on the XL2411P.

Some informatioon on DVI-DUAL Link.

[madridm]

Yes I did :( 

I am just confused why Nvidia does it and not AMD.

[colesdav]

Is this your monitor:
https://xsreviews.co.uk/reviews/benq-zowie-xl2411-review/

It states the Monitor has the following inputs:
DVI Dual Link, HDMI, VGA.

Is that the correct inputs that are available on your monitor?

[madridm]

yes they are the correct inputs, but just DVI DL allow 144Hz

As I mentioned my video card do not have DVI, just DP and HDMI, I am using an Adapter DP to DVI same used with the 1070ti and He was getting 144 Hz, I am not.

[colesdav]

Sure, understood. Thanks.

I already ordered another cable, and Active DP 1.2 to DVI Dual Link that should handle the 144Hz. I will let you know how that goes. The old cable works in another just 60Hz monitor, maybe it went bad, I will see.

[colesdav]

I am testing an RX5700XT for a PC build on another PC.
I will go look see what options are available on Adrenalin 2020 20.12.1 Drivers for that GPU.

It should have the same options as your RX5600XT.
I will also look at the registry entries.

Meantime check the cable you ordered supports DSC.

OK?

[colesdav]

I checked Adrenalin 2020 20.12.1 on a RX5700XT.
I looked at the Custom Resolution and Advanced options.
Nothing obvious there.

So it might be a delve into registry entries to change DSC behaviour. 
In that case please open a email support case with AMD here:
https://www.amd.com/en/support/contact-email-form

These have an indirect control on what DSC does:

I assume you have already tried this but just in case.
Pixel Format.
Nvidia GPU setup used to set RGB  4:4:4 Studio (Limited)  by default.
Color Depth
Have you set the Color Depth to 6 bpc ?

[colesdav]

If you check on the Nvidia Forum you will find a discussion where it is confirmed that Display Stream Compression (DSC) is not fully implemented on Pascal GPU hardware and so the full DisplayPort 1.4 specification is not implemented. 

I will not provide the link to the Nvidia Forum here, as some people will not like that and accuse me of working for Nvidia again. 

It is fully implemented in Turing GPUs. So you could try the adapter you have with an RTX2080 for example and see if it still works. 

That is likely one reason why it works o.k. with the DisplayPort Adapter on the  GTX1070Ti, but not with the AMD RX5600XT.

DSC. 

[colesdav]

You might need Active DP 1.4a to DVI Dual Link cable if such a thing exists. 

[madridm]

The new adapter should come in tomorrow, I will let you know if it works. Thanks for being so helpful.

[colesdav]

Thanks for letting me know. 
I hope the new cable works for you o.k. 
I definitely confirmed that the hardware on the Pascal Cards is different to Turing w.r.t. DisplayPort 1.4 support & DSC. 

Good Luck.

[madridm · Accepted solution]

The cable works perfectly at 144Hz. My problem is solved but the mystery of why it worked with an NVidia card still unsolved.

Thanks for everybody that gave me their inputs.

Hello i am using an nvidia graphics card and i am having the same problem with Dvi cable so if i bought this product it will be solved https://www.amazon.com/VisionTek-DisplayPort-DVI-D-Active-Adapter/dp/B00DYRQXMK

[colesdav]

Specifications for the GTX 1070Ti reference card is here:
https://www.nvidia.com/en-gb/geforce/10-series/#1070-ti-spec

GTX1070Ti reference had the following outputs:

DP 1.4 (Note 3), HDMI 2.0b, DL-DVI DP 

Note the fine print though:

Note 3 - DisplayPort 1.2 Certified, DisplayPort 1.3/1.4 Ready.

I do not think the GTX1070Ti had the required hardware to implement DSC - Display Stream Compression on the Pascal Series GPUs. 

I think that was implemented in Turing GPUs for Nvidia GPUs.

So it may well be that yourr old adapter could work on your new AMD GPU, if you can turn off DSC through the drivers or registry entries for the RX5600XT GPU.

HDMI will not give you more then 60 you need DP to get it to 144 I have 144 monitor and I am  using DP

"To output 1080p content at 144Hz, you will need either a Dual-Link DVI, DisplayPort, or HDMI 1.4 cable (or better). However, note that some monitors with HDMI 1.4 are limited to 60Hz or 120Hz."

[Catscratch]

It's definitely monitor and cable specific. I'm on AOC 24g2u with the provided hdmi cable connected to RX 580 and it can do 144hz on desktop.

[AladdinGamall]

I have DVI to HDMI cable and my PC have only 60hz option . If i buy DVI to Dp, will I be able to run my of on 144hz

[akiatsu]

I have the same gpu and monitor like you, and im about to order the convertor you are using. THANK U SO MUCH, genuinely! i really hope its gonna work @colesdav @madridm
