Ok. Glad that both monitor lasted till almost 4yrs. After the small hiccups on one of the monitor about 1.5yrs mark .... now the other monitor is having a slight issue.
Please see video for the fault.
looks like power supply needs to be replaced
You mean you tried swopping over the power supply from the working set?
If not.. PCB fault again![]()

I am running dual CrossOver 27Q 27 inch QHD now. If this is power supply issue, how come this only happens to one of them?
The interesting thing is that when I am playing game (gfx card is on load), the monitor is ok. This only happens when the monitor goes to "sleep" and wake up from it.
It is also not consistent. Meaning that last night, when I "wake up" my PC, I kana. But this morning, it was fine.
I have found the cause of this problem.
The power adapter is faulty. I plugged the same power adapter to another monitor and it has the same problem.
CAUSE OF THE PROBLEM : FOUND!!
Now trying to get the power adapter.

Hi guys,
I also got a problem with my 3-yo 27Q. Sometimes when booting up, the desktop successfully goes into Windows (confirmed because there's sound), but the monitor refuses to show anything. I have to restart many times before it will show something on screen again. It's all good when it's on though.
Anyone else has this problem? Is it the LED board issue or?
The left section of my monitor is flickering intermittently.
Any idea if it is due to power adaptor? Thanks.
Just a BIG note here
Bought 2 x CrossOver 27Q QHD 27 inch monitor with Pivot on 21 May 2012 from EBay.
Around Jan 2014, one of the monitor has a failed LED Driver board :

Managed to get the seller and paid about SGD$60 for the replacement. It is working well so far.
This 2 monitor lasted past 4yrs already. So hope that both will last pass the 10th year mark.
Yes. Sound very much like the problem that I am having now. Once the monitor is ON, it'll be ok.
Should be power adapter problem liao.

Only left section? Very hard to tell from your description. But you can try shifting the position of your power adapter and try to put it at a more cooling spot and then try again. Since the power adapter can be quite warm.
saw your YouTube video - mine doesn't have the intermittent flickering issue though. It's either fully off or fully on. Also, mine only happens during boot time. Is it still the power adapter issue?
If so, how much would it cost to replace?
Mine is around the same age as yours, so far no issues but my room is well ventilated or air-conditioned. Gonna upgrade around end of this year though haha
any idea if the LCD/LED tech have improved over the last 4 years since Crossover 27Q came out? Toying with the idea of buying a 2nd korean monitor (only if it's better quality and similar price to the 27Q).
