[SOLVED] 4K 144 Hz gaming monitor NOT WAKING UP!

[TeioDra]

Hi guys!

This is weird, but I didn't manage to find any answer, not even on the Acer forum. And it's been two years since I have this monitor.

I have an Acer Nitro 27" XV273KPbmiipprzx 4K 144Hz gaming monitor.
At default, it runs at 120Hz, on one DisplayPort 1.4. The monitor goes to sleep and wakes up normally.
***Please note that this display uses 2 x DisplayPort 1.4 (the 2nd one is for 144Hz mode). In Windows, I’ve set Multiple displays to ///Show only on 1///.

When I turn 144Hz mode on (from the monitor’s menu), all is normal, until the PC goes to sleep. I just can’t wake it up, unless I restart the PC from the MB (the case doesn't have a reset button). The monitor goes into a no source state, and it keeps on searching for inputs, and then it hibernates. The PC wakes up and is running, but I guess it’s bricked, or something, as I can’t restart it from the keyboard.

I just want to use this monitor at 144Hz, all the time, without switching from 120Hz to 144Hz all the time. I’ve been fiddling a lot with this, so, hope for some new advices.

Thank you,

sounds like you have a deeper issue with power or something else.

i've run many 120Hz, 144Hz, 165Hz, 240Hz displays through different systems and never was a secondary display cable needed to attain these refresh rates.
even if a a bit of "overclocking" is required to reach 144Hz it shouldn't require a secondary cable.

you should contact Acer directly and explain your situation.
if they have no decent explanation or easy fix you should return this display and get something that works natively.

I think it has something to do with the signal transmitted from the GPU, after waking up. Being set to //show only on 1 display// and having 2xDisplayPort enabled, may cause a miscommunication. The thing is that even if I set Windows to //duplicate these displays// the same problem appears. I've waited for windows/new drivers to maybe solve this hiccup.

I can send it back, as it's warranty will end in a couple of weeks. Though, I've sent it back, when I bought it, as it had a dead pixels spot. And I've waited for too long, for that repair.

tomshardware have a review on this monitor. This is what they stated regarding 2 x DisplayPorts:
"You also get two DisplayPort 1.4 and two HDMI 2.0 inputs. Why two DisplayPorts? Because connecting both to an appropriate graphics card will give you the full 10-bit signal depth for 3840x2160 resolution at 144Hz. If you use a single cable, the refresh rate is limited to 120Hz. Competing monitors, the Predator X27 and Predator XB273K, make do with a single DisplayPort connection; they reduce bandwidth to achieve full resolution at 144Hz."

If you use a single cable, the refresh rate is limited to 120Hz

144Hz vs 120Hz really isn't that big of a difference.

if you're running 2160p with HDR enabled then i doubt you'll even be getting 120fps in the majority of games out there so using 120Hz should be fine.

maybe Acer will release a firmware update down the line that could correct the issue and you'd be able to enable 144Hz but it still wouldn't make much of difference for you, if any.

Before gaming, I always enable the 144 Hz mode. For multiplayer shooters, of course. With DLSS I can get a constant >144 FPS. So, why not have the full 144 Hz?

The problem is that, if I forget to dial back to the 120 Hz mode, after gaming, and the monitor/PC go to sleep, then I can't wake them up, it bricks. I have to remove the glass panel from my case, to get access to the RESET button on the MB. It's really annoying.

In the end, the monitor was marketed as such, it was paid for, and should work. I haven't found any new (or any) firmware on their site. It is what it is.

Clearly, this is a problem which won't be fixed, as new products are released frequently and the old ones get forgotten.

Still, if someone else, who has this same product, could check this issue, that would be a first step for me.

this is not necessarily true.
i've had some boards that are 5+ years old that have still received BIOS, firmware, and driver updates.
older TVs that still receive updates.
and my Alienware display is 2 years old and also regularly receives updates to it's control software and firmware.

So, why not have the full 144 Hz?

because,

if I forget to dial back to the 120 Hz mode, after gaming, and the monitor/PC go to sleep, then I can't wake them up, it bricks.

if you're fine dealing with this over and over then no problem.

i would return this thing if you're still within the retailer's return/refund window though.

Sent them an e-mail today. Waiting for their reply. Though, they might say that the 144 Hz mode is working fine. Waking up from sleep might be a Windows / GPU problem. And I don't know how to look at this.

 

[JohnBonhamsGhost]

I don't know how to look at this.

i don't believe there is any problem here.
you've already proved that this dual cable design is the default setup.

the issues that occur because of it are just attributes that are included.

if you don't like the outcome;
exchange this display for something better,
or just be disappointed and live with the issue.

we could hope that through later driver or firmware updates that it could be corrected but it seems to have just been designed this way.

No warranty left. I guess that this is the way to look at this, as you pointed out. Great pov/advise! Thanks!

Connected the two DisplayPort 1.4 cables to a Radeon RX 6950 XT. The problem disappeared. I guess that Radeon works with this configs. Maybe, because the monitor is FreeSync, and G-Sync compatible, something related to that.

good that you found a solution, even as expensive as it may have been.
you should also share this with any threads on the Acer forums you may have found mentioning similar issues.

Oh my God! This isn't ending. The RX 6950 XT Pure I just got, is able to instantly wake up from sleep, in the 144Hz mode, so, problem solved. BUT, Radeon's Adrenalin software sees my monitor as 2 monitors 19202160 / Windows sees this as 38402160. So, in order to use FidelityFx Super Resolution, I need to lower the game's resolution, and I can't, because of the 1920*2160. I'm posting this, as I'm thinking of returning the card. Nvidia is so much simpler, out of the box. I mean, how much should I tinker with Radeon's software to get fluent gaming? It stutters so messy, it's like a machine gun.
