Connecting Razer Blade 14 to Acer Predator 27" XB271HU with high refresh rate + 2K + Gsync

Dbrown8630

Hi everyone,

I am trying to figure out how to connect my razer laptop to my newly purchased Acer Predator 27" XB271HU. The laptop only has an HDMI port. I can connect it through HDMI to my screen with 2560 x 1440 resolution and 60Hz (it actually says 59.951 Hz when I check the display settings).

However, I would like to have 144Hz (maximum refresh rate of the monitor, I do not wish to overclock) and 2560 x 1440 resolution. I have purchased an HDMI to Display port cable for this, but when I connect his to my laptop and the monitor it does not display anything (I changed the input to DP on the monitor and rebooted my laptop).

I purchased the monitor to game in 2560 x 1440 resolution and a high refresh rate and to enjoy Gsync. But the only function I have now is the right resolution (no high refresh rate and no gsync available in NVIDIA settings or display settings).

So I am not sure what I am doing wrong. I have called Acer about this but they could not help me out and asked me to make a post here so I was hoping someone else could help out.

Here are the specs of everything I mentioned before:

Razer Blade 14 14" 165Hz QHD Matte Display AMD Ryzen 9 5900HX RTX 3070 8GB VRAM/ 16GB RAM/ 1TB PCIe SSD Laptop

Acer Predator 27" XB271HU ZeroFrame Gsync WQHD Monitor

Hope I can find the answer here! Thanks everyone

@Dbrown8630 I think this older monitor model might be 60Hz capped for the HDMI port. Check in Nvidia control panel to see if you can create custom resolution for higher refresh rate. Or you can use USB-C to Display-port cable but one thing that I am concerned about is that the USB-C port might be connected to internal AMD GPU rather than Nvidia GPU. Another solution is getting an Active HDMI to Display Port cable (make sure the title is listed like that because they are not bi-directional), read the description carefully and reviews to see if that converter cable can support 2K 144Hz or not.

Here is the example one that might work.

Thanks for providing me with this info AnhEZ28! I was already thinking that I might need an active cable, but thought something else might be wrong after getting the cable that I mentioned in my first post. I will give it a shot with the cable you send me through, do not want to take the risk as you have mentioned with the cable through the usb C port. It will take a few weeks for the cable to get here, but hope it will do the trick. Thanks for taking the time to help me out!

Sorry for the second post. But just about to order the cable and I was just wondering why my original hdmi to dp cable does not put any signal out to my monitor? 2k 60hz works with hdmi but when I connect my hdmi to dp cable there is no signal at all, not even 2k 60hz? Makes me wonder if I was doing anything wrong before buying another cable with possibly the same result.

That cable is DP to HDMI, not HDMI to DP. One way is easy and cheap, the other harder and more expensive.

Oh I see, I was not aware of that! All good, I have ordered the cable which should be here at the end of the week. Thank for providing me with some clearance everyone

Make sure to let us know how it turns out with the other cable, either way. :)

Hi again everyone, I appreciate everyones input here. The cable has arrived and it is working but not 100% the way I expected it to work.

• I am still unable to activate Gsync when I go into Nvidia settings. I do not see the same option like I see in this screenshot: https://i.pcmag.com/imagery/articles/03iskcd57hilEEFERxHhQzv-3.png
• There is no Set up G Sync option and the screen is capable of G sync so I am not sure what the problem is, it was the same when I connected through HDMI
• 
  
• The other thing is that under advanced display settings in Windows I can chose 6 different Hz settings: 23.971, 59.951, 84.983, 99.946 and 119.998 Hz.
• I pick 119.998 Hz but the monitor is capable of 144Hz and even more if I would overclock it but I do not wish to. I was just wondering if there is a way to make it work to 144Hz?

If I could get G sync working somehow I would be happy with the 119 Hz, but even better if there would be a way to get both 144Hz and Gsync work.

Thanks for the help again!

@Dbrown8630 it might be the limit of that cable converter. You can try to create custom resolution in Nvidia Control Panel or might try to turn on the Overclock and set it at 144Hz.

I think you are right about the cable. When going through advanced display settings it only goes until 120 Hz, which is fine for me.

What I would like to figure out is how to activate G sync, is there a possibility to have this setting showing up in my Nvidia Control Panel, because this is not the case now. Happy to hear what anyone has to say about this issue :)

billsey

It's very possible the cable doesn't support doing the G-Sync translation, or the monitor only supports G-Sync on the DP port.
