XB321HK Weird Artifact

adamlreed93

Im going to buy a grounding cable to connect to the base of my Acer Predator XB321HK as I stated earlier that I can make my screen flicker almost anytime I want with static electricity touching the base of the monitor. I will report back on Saturday or Sunday

My monitor is properly grounded, I've tested earth continuity - I believe both by USB earth and main earth. Hence I don't think adding extra earth connection will change anything.
Touching it makes no flicker appear. 
But my flickering is pretty rare, so I assume it may be a case that poor grounding will make flicker more often. Though its pretty clear that good grounding is not enough to eliminate flickers completely.

Gounding cable didn't help, yet i can still touch the base of my monitor and get it to flicker

I suspect it may to do something more with EM interference than electrostatic charge (your body acting as antenna increasing offending EM signal).
Grounding won't help against radio waves - you need shielding. However, any kind of outside shielding will not be effective since screen will act as massive transparent "window" - shielding the electronics will require panel disassembly which would be hardly feasible.

Returning to Acer for repair or swapping, which I've read they will not find anything and send back but I have to give it a shot, right?

They can't repair this. If they could they would clearly announce it ages ago, but they didn't (and now deleted all posts when they even promised a fix).

They will try to make it appear they "meet their costumer care obligation", by claiming either "repair attempted" or "no fault found". Either way you won't get it fixed - and will just waste a time. Best you can hope is to get panel which glitches less often - but then, you may get panel worse in other respects (e.g. dead pixels, light bleed).

I think its only worthwhile trying to involve Acer warranty repair if you intend to fight all the way - involving consumer protection bodies of your country to force Acer legally at least to provide you with a full refund or other equivalent monitor model without issues (which I don't think exists, so refund will be only option). To involve customer protection bodies you will have to demonstrate that you tried to resolve problem through customer care channels and Acer failed to do so. This will take quite a time & effort so its up to you to decide if its worth it.

Well I do not have dead pixels and the monitor does NOT freak out every 30 seconds, So you have put some doubt in my mind. Getting a monitor that could be worst would be very irritating to say. Decisions

I've begrudgingly decided to live with mine, since buying new monitor is nightmare nowadays and it had me 2 monitor exchanges to get the current one without significant optical issues.

But one thing I know for sure - this will be the last Acer product I bought. Fool me once... Actually this will be the last "pro gamer" brand product I bought. I will just stick to business-grade monitors - they don't have as many feature tickboxes, but tend to be actually much more solid as monitors.

I have the same issue with my XB271HK - just spoken to Acer Support and have been told that this has not been confirmed for this model...and around we go again...

Manny-Acer_Retired

Hi WestWorld27,

Sorry to hear that, can you please send me a PM with your serial number and the contact center number you contacted for follow up?

Thanks,

@Acer-Manny, thank you for acknowledging the issue and most importantly, that it can be fixed.

Can it be done by the user simply downloading and applying a firmware update or does it need to be sent to Acer Support to replace some hardware?  I'm worried about how many days/weeks I will be left without a monitor (in Australia).

Hi Acer-Manny, 

I'm happy to hear that you've managed to resolve this issue with xb321hk model.

But, does it mean that you have a fix for xb271hk as well?

There is a similar thread on this forum regarding xb271hk:

https://community.acer.com/en/discussion/456382/xb271hk-flickering/p3

Could you post your message there as well?

I also second M10's post. Can we apply this patch by ourselves? 

I have a bad experience with customer support in general (I live in Poland) and I don't want my monitor to be swapped etc.

Manny-Acer_Retired

Hi M10,

Unfortunately the fix involve a Hardware repair so the LCD needs to be sent to your local repair center.

MrDonkey - For the XB271HK monitor Flickering problem we had a solution as well for quite some time, even do they look like very similar problems the diagnose of the issue and fixwas different but the monitor has to coming for service as the fix is also a hardware one. I appreciate that you brought this to my attention, i will make and official notice to the post.

Thanks,
Acer-Manny
