Asus Pg27aqdm Turn off issue infinite pixel cleaning loop

[berozzscorpion]

Hi there . So i dont know why but the asus pg27aqdm suffers from a problem when turning off the display.

So what exactly is the issue? Well if you turn off the display while your pc console or whatever is shutting down and you decide to turn it off while it does as anybody would probably do the display will get stuck in an infinite loop (literally) of running the pixel cleaner / being active. I researched the issue for a while now and after tesing myself i came to the conclusion that the turn off mechanism is glitched and needs to be fixed by firmware. If you decide to turn the display off after your pc or console has shutdown you are good to go it will run the 6 min pixel clean and then turn off itself .

Yet if you decide to turn it off while your pc or console is turning off it seems to get stuck in an infinite loop of running the pixel cleaner.

If you decide to turn off the display while its in standby (orange led indicitaor) it will skip the pixel cleaning completly and just turn off wich i wouldnt recommend at all since the pixel cleaning is important.

Every time i turn off my pc i have to wait till its completly off and then to turn off the display before it goes to standby so it runs the pixel cleaner and shuts off as it normally should do under any condition. It seems that the input source disconecction interrupts the monitor somehow that it gets stuck in an loop. I do hope that asus fixes this issue as they did with the HDR issues wich iam really glad of 

The issue Occurs on all firmware versions mcm 102, mcm 103, mcm 104 and mcm 105

Hi @berozzscorpion ,

based on your question, I understand that the issue occurs when turning off the monitor while the computer is shutting down, resulting in a continuous pixel cleaning loop.
Could you clarify the color of the monitor indicator light when this issue occurs? 
Does the pixel cleaning on the monitor continue once the computer is completely shut down, as you mentioned entering an infinite loop?
To better assist you, could you please provide separate recordings for the following scenarios:

1.When the computer is completely shut down, then you turn off the monitor, and the monitor executes the pixel cleaning for about 6 minutes before turning off.

2.When the computer is in the process of shutting down, you turn off the monitor, and the monitor enters into the pixel cleaning loop.

Please provide these two videos for our reference. Ideally, video 1 should show a normal behavior, while video 2 should demonstrate the issue you've described. Thank you.

Hi @Aureliannn_ROG 

I filmed 2 videos on the first clip turned off the monitor while the pc was shutting down i checked on the monitor after 6 minutes the back leds were still on so i assumed it was still running the pixel cleaner. I let the timer reach about 11 Minutes before turning off the clip  and the display still was looping the pixel cleaning . I once left it in that state ( a long time ago in summer ) for 4 hours after coming back to the monitor i saw that the led lights were on in the back were still on and after pressing the power button again i saw had a very weird purple type of stain on the monitor due to the sun shinning really bright uv rays onto the display while the pixel cleaner went on for 4 Hours. Luckily it wasnt broken and could be fixed by a pixel cleaning and leaving the monitor off and disconnected from the power for a few hours

On the second clip i turned the monitor after the pc has been shutdown completely and then afterwards  i turned off the monitor while it displayed the no input signal message so i knew it was safe to turn it off. It was a bit hard to film sometimes the cam went unfocused but i captured the issue. The indicator light was off as seen in the clips .

So i came to the conclusion that the infinite pixel cleaning loop occurs when the inputs source gets disconnected (due to the fact that my pc was shutting down causing it to get disconnected) causes this infinite loop of the pixel cleaner . As also seen in the clip below if you decide to do it after the pc has shutdown (or even while its on not shown in any clip tho )  it will do as it should do normally doing the 6 min pixel cleaning and turning itself off completly. This issue has been reported by other people  as well yet not anybody described it as detailed as i tried to do it here . i think this is fixable by firmware.

Here are the clips i also included an stopwatch on the bottom of the screen and used the back leds to see if the monitor is stuck in the loop or not.

Clip 1 (Turning The Monitor Off while the pc is shutting down) 

https://mega.nz/file/qdEniarB#Rn5YS7vXygmTg_dT7fomi_OocVoX8cmsCcO5OAF-DFE

Timestamp 1:  6:55 

I checked the back leds and they were still active after the pixel cleaning should have been done

Timestamp 2: 11:30

Right before i ended the clip i checked the back and it was still stuck in the loop i could have let it in this state for an hour and even more and it would stay in that pixel cleaning loop sadly.

Clip 2 After Turning the pc off (Normal Behaviour)

https://mega.nz/file/iMcxQB7Z#ZeI3RI2daRYWfS5EhtSJ8KAquiX25MYZdsYVGhYgCcs

I noticed that in the recording the back led lights were not captured at all   by the cam for some reason it focused more on the ipad screen yet i can confirm to you that the monitor was completely off after 6 mins . During the 6 min the led lights were on and after the 6 mins they were off indicating to me that the pixel cleaning was done correctly and it shut off itself.

The indicitaor light is seen in both clips and appears to be off as i stated before iam pretty sure its the input signal getting disconnected causing this annoying loop . Its pretty annoying having to wait till the pc has shutdown completely and then turning it off before it goes into standby mode to turn off the monitor correctly . 

I hope these clips can help you understand the issue more so you can share them with the relevant departments for further inspection and hopefully an fix for this issue. Thank you 😄

Hi @berozzscorpion ,

according to your question, we would like to reconfirm. 

If you turn off the PC without manually turning off the monitor power key, does the monitor perform the 6-minute pixel cleaning normally (please note if the indicator light on the monitor is lit orange)? 

The location of the power indicator light is indicated by number 4 in the diagram below.

According to what you said, during the process of turning off the PC, if you manually turn off the monitor power key, the monitor screen will stay on and not turn off. 

Can you confirm the color of the monitor's indicator light at this time? 

Ideally, turning off the monitor should result in no display. 

Please provide further clarification.

Thank you.

Hi @Aureliannn_ROG

I Checked the indicator led during all of these procedures. 

1. Turning off the monitor while the pc is shutting down (Infinite pixel cleaning loop issue)

The Indicator LED is off for the entire time after pressing the powerbutton. The back Aura RGB LEDs wich i used to measure if the monitor is stuck on the loop are on during the entire time.

Power Indicator is off completely as seen in the videos I did.

2 . Turning Off the monitor after pc has shut down (6 min pixel clean and the turn off as the monitor should do)

The Indicator LED is off the entire time after pressing the powerbutton (The back AURA RGB LEDs are on for 6 Minutes. After the pixel cleaning is done they turn off and the monitor is completely shut down.

3.Dont turn off the monitor manualy and let it go into standby. 

I tested this today . I turned off my pc and didnt turn the monitor off i decided to also track the time with an stopwatch and concluded to these things. After the pc has been shutdown it displays an no input signal message wich then dissapears after that the led indicator turns orange (Amber) . After 5 minutes later the Indicator flashes about 3 - 4 times and the light stays amber afterwards. (Im not sure if the display is looping in this scenario) i would assume that when the amber indicator blinked that the pixel cleaning was done yet i cant confirm this.

For reconfirmation the issue is that the display will get stuck in an infinite loop of a pixel cleaner if you decide to turn it off while your pc/console is shutting down causing the monitor to get stuck in the infinite loop of the pixel cleaner. At first i thought that the display is basically off and the AURA RGB LEDs are on .

The only way i found out that the pixel cleaner is running is due to the image retention (purple stain i mention in the second reply) i got while the sun shined with bright UV Rays directly onto the display while the pixel cleaner was probably running the entire time for 4 hours.

Quote From second reply

 " I once left it in that state ( a long time ago in summer ) for 4 hours after coming back to the monitor i saw that the led lights in the back were still on and after pressing the power button again i saw had a very weird purple type of stain on the monitor due to the sun shinning really bright uv rays onto the display while the pixel cleaner went on for 4 Hours."

Due to this i assumed that the issue is infact the pixel cleaner being stuck on an infinite loop wich is not good for the monitor and also causes unscessary power consumption and wear down of the oled till you press the powerbutton to use the monitor again. 

this issue only occurs if you turn off the monitor while the pc/console is shutting down and is a flaw with the turn off mechanism. 

If hope this helps you understand the issue more so it can be fixed. As mentioned in first post this issue occured to other people as well. By coincidence i found that the pixel cleaner is stuck in an infinite loop wich is why many people reported that their display didnt turn off completly/correctly.

Hi @berozzscorpion ,

thanks for providing the details information, we appreciate that.

Regarding the third point "3. Don't turn off the monitor manually and let it go into standby." 

Could you clarify if the indicator light flashes three to four times and the backlight LED continues to stay on as in scenario 1, it did not turn off after 6 minutes? 

In the situations you provided (1/2/3), does the monitor still display an image, or does it stop displaying a picture when the monitor is turned off, while the backlight LED remains on?

Thank you.

Hi @Aureliannn_ROG 

On scenario 3 (Dont turn off the monitor manually and let it go into standby) The back led remains on all the time even after the flashes Im not sure if this Indicates if the monitor is stuck in the infinite pixel cleaning loop as i couldn't really check if its pixel cleaning in the standby mode.

In situations 1 - 2 The monitor doesn't display any image after pressing the power button even if its stuck on the pixel cleaning loop or not (Scenario 1) . The back LEDs stay on all the time as for the pixel cleaner running infinitely .  and in Scenario 2 The Back LEDs turn themselves off after the pixel cleaning is done (6 mins) and the monitor seems to turn off completely/correctly.

On situation 3 The monitor just displays the no input signal message for a few seconds after pc shutdown then the screen doesnt display image. After the flashes end the monitor still doesnt display any image. The Back LEDs remain on . I cant tell in this case if its stuck on the pixel cleaning loop since i found it on coincidence on scenario 1 but i would assume its normal for the AURA RGB Lights to remain on in standby. Yet its kinda weird that the flashes occur after 5 minutes and not 6 .

As mentioned before i think the Input source getting unplugged is causing the loop and i decided to also test this today. I turned off the monitor while my pc was on and during the pixel cleaning i just unplugged the display port at the back of my pc and it got stuck in the infinite loop that occurs.  I also decided to test what happens if i plug in a input source after pressing the powerbutton while i had an console plugged into the monitor. And the loop didnt occur . The loop only occurs whent turning off the display while the pc is shutting down or if you unplug an input source while its doing the 6 min pixel cleaning wich causes the loop to occur that other people reported aswell. 

I hope this information can help the issue get fixed  and it actually seems to be the input source getting disconnected/unplugged .
