VG270UP flickering Iissue - innolux panel

robertogl · June 2019

Hi,

it appears that all the monitors with the same Innolux panel (27 inches, 1440p, IPS, 144Hz) suffer of random flickering. That is the case of the VG270UP, VG271UP and XV272UP for Acer.
I've found similar post on this community about the issue, but none of them has a solution.

Acer, do you have more information about the problem?

Thank you.

Hi @robertogl

Try doing a power drain, by press and holding the power button for about 30 secs. also do a monitor self test by plugging the power cable alone and turn on the monitor, after acer logo if the display flickers then it is something to do with the hardware of the monitor. if the display appears to be normal then the issue might be with graphics card of the computer.

Hi @Du_little

I don't even have the monitor yet. Reports of flickering are all over internet (well, where we talk about monitors). I'm not buying it because of the issue.
You can find reports also here, on the Acer community, of the same issue.

A lot of people are sending back the monitor to Acer, just to get a monitor with the same issue. It does not depend on the card, as we have reports from Nvidia, AMD, or Intel owner.

Hi,

just here to keep the thread alive.

Have you tried lowering the monitor refresh rate? Are you using an hdmi or dp cable?

robertogl · June 2019

Hi,

the issue is not related to cables or monitor settings. You can find here a lot of reports from the VG270UP, but also from all the Acer monitors with the Innolux panel (links to just the Acer community, but you can go over to reddit for example and check also there):

People have sent the display back to Acer just to get back a display with the same issue. Happens with HDMI or DP, happens at every refresh rate (but well, it should not happen even at 144Hz, as the monitor is advertise as 144Hz capable).

We just want to know that Acer is looking into this, the problem is that the issue is present from Day 1 with this panel. In case of the VG270UP, this means 8 months ago, and not a single word from Acer about the issue.

I checked that you participate in the discord community too! If I'm not mistaken, Acer has released a fix through a firmware for this notebook model! However, you must contact Acer technical support!

robertogl · June 2019

Hi,

yes, I'm on the discors channel too. There are some reports of this 'fantomatic' new firmware, but none of the people that sent the display to Acer got back a working unit. So I don't think that it actually exists.

About the firmware, you can either ask directly for technical support !, or by sending a private message to the moderator Acer-Manny! Now, does this flicker occur when you disable freesync?

robertogl · June 2019

Hi,

yes, it occurs with freesync enabled or disabled. No difference.
I will contact Acer-Manny, but I'm pretty sure that no firmware exists with the fix.

It looks like there is a new firmware version for this monitor, see: https://community.acer.com/en/discussion/comment/658930/#Comment_658930
However, it looks like they are replacing the monitor hardware! Can you still replace the monitor with the seller?

robertogl · June 2019

Hi,

if you look at the answers by Antoine008 (that got the new hardware) on the same thread, he says the new unit still has the same flickering issue.

Roberto

Hi,

Acer-Manny suggested me to change the panel. As other users reported, this is not a solution at the moment, so I'm still waiting for some new informations from Acer.

Regards,

Roberto

Commodore_1995# · June 2019

Have you contacted Acer technical support directly?

robertogl · June 2019

Hi,

yes, I'm having a conversation also with the Acer support, but at the moment the only answers are 'Did you send back the display?' or 'We don't know any problem on this monitor', so nothing usefull.

Roberto

Commodore_1995# · June 2019

I think it's very likely a problem on the display, but have you tried disabling overclock on the monitor if this option is available?

robertogl · June 2019

Hi,

it is a problem with all the same Innolux panels, like I said. I'm going to continue asking Acer about it. The reports of different users are here, it is NOT a single unit that shows the issue.

Roberto

Can you tell me the idhardware of this monitor? Example of how to check the idhardware of a device:

That way, we would have more information accessing the site panelook!

Maybe this will help you: https://www.reddit.com/r/nvidia/comments/agcj4a/how_to_eliminate_flickering_on_gsyncfreesync/

Remember that the CRU program should be used with caution as it may violate the hardware warranty!

robertogl · June 2019

Hi,

the issue happens also with Freesync disabled, so I don't think that the proposed solution can help.

As Hardware ID, I got confirmation of 'MONITOR\ACR06CF'.
