Swift starting to die ?

Probably - my 3rd RMA replacement started doing that so I ended up buying the Dell S2716DG instead - surprised you got 3 years out of it the rate they tended to die.
 
The only thing you can try is swapping out the Displayport cable, it probably won't help but at least you'll know, and maybe a driver wipe.
 
The power adapters on these are the biggest failure point, I’d recommend replacing that and the DP cable to try and get more life out of it.

Otherwise it might be the monitor itself.

That tiny no doubt cheapest acceptable brick is definitely rather horrible looking for durability...

Connector is likely standard so there might be non-branded regulated DC power supplies with same voltage and at least same output current capability.
Though if that brick is failing it could be also wearing out components inside monitor.
 
They are pretty nasty 2 of the ones I've got hold of are like this on an oscilloscope:

Under heavy load they are actually a lot worse than that with the voltage spiking considerably above 19V and then dropping down until it suddenly bounces back to 19V not just under light load or unloaded.

I replaced mine with a generic Asus F3S 19V 4.74A LAPTOP CHARGER 2.5MM power brick but that is only half what is wrong with these monitors - internally they are pretty poorly slapped together and I suspect like on my latest one the DP socket itself is coming loose inside.

Hope I'm not jinxing myself but so far the Dell S2716DG has been a considerably better monitor.

The main issue with those monitors that kills a lot of them is a combination of poor design which results in heat pooling on the bottom right side of the monitor about 10cm diagonally from the bezel towards the middle and related to that nearby a component that easily becomes a pass through for long term current leak to ground which isn't designed for that load and eventually wears out (compounded by the poor power regulation from the cheap and nasty PSU).

Oh god, the more I read on this the more I'm thinking to just dump the monitor lol

ASUS want £45 for a new power supply from themselves :(

OK I have one of these

And over the last week it's been flickering on and off and random times , I got it B-Grade about 3 years ago and until now it's been perfect , is it starting to die on me ?

thanks :)

I've got one of these monitors and it kept turning itself on randomly, so I bought a third party power supply which fixed the turning on and improved the picture quality!?!?!

I was never happy with this monitor but now after owning it for over 18 months the picture is what I expected it to be. Weird I know, god knows what was happening with the other adapter but whatever was happening was from new! It was almost is if the panel was power starved so not fully driving the pixels correctly which created a subtle blockiness to the picture what has now been smoothed out.

Last Asus I buy.
 
Yeah I wont be buying anymore monitors from them either , next time I'll be going to Dell I think , have to say though I've never thought the picture quality or sharpnish ?...was anything to shout about , in fact it's about the same-ish as my 34" that sits next to it , and I cant really dump the monitor as I dont have another to put in it's place .

See my post above - the power adaptors I've managed to get my hands on from these have shocking regulation and other issues and wouldn't surprise me if somehow a better adaptor resulted in better performance of the monitor.

Also in my experience the panels in these (same one used in the Dell and Acer equivalents, etc.) "settle" over time with a slight improvement to colour accuracy - my first one for instance has a slight reddish hue out the box which I offset with calibration a few months later I had to redo my calibration as it was no longer having the desired effect and resetting to out the box defaults no longer had that slight red bias. Same with my Dell - the settings I originally posted in the relevant thread I had to tweak slightly later.

Also seems to have not so great ripple performance or some faster scale regulation problem...
Even if cooling wasn't bad that's going to put stress on monitor's components...
And I guess they've also sticked some electrolytic capacitors to hot place as "back up timer" to quarantee break down fast enough.
(like Samsung has done in the past in monitors and TVs)

So overall quality seems like standard gaming trinket:
Low quality design and parts with of course gaming product profit margin.

Seems to be par for the course (though not so bad) for a lot of mainstream consumer devices :( and in most cases only saving a tiny amount (though I guess it adds up in the bigger volume of mass production) on the cost of better electronic components.

Same or very close voltage is important.
Max output current must be at least same or preferably little higher:
Voltage regulation and ripple filtering are likely to stay better if power supply isn't stressed as much.
And something makes me suspect that bundled power brick is "optimistically" sized.

Of course connector needs to be same sized.
Seems to be one also used in laptops:
https://forums.overclockers.co.uk/posts/31575222

There are also selectable voltage "universal" laptop power supplies with even switchable connectors offering voltages like these:
15/16/18,5/19/19,5V
Might be easier to find such than fixed voltage power supply.
Just remember to check power rating or output current for needed voltage.
(they give more current at lowest voltages)

I think small cost saving for low quality/undersized filtering capacitors isn't only reason.
Makes sales lot better if things break after couple years instead of product being able to keep going for something like decade.
For some reason "environmenalists" just never seem to be interested on that "disposable product" culture...

You want something that outputs 19V - from what I remember looking inside probably its tolerant of a few volts above that but not worth risking it - IIRC in tests it pulls about 55-60 watt max from the adaptor but the stock one is 90 watt IIRC so you'd probably want to aim for about that (19V - 4.7-5amp). With a 5.5mmx2.5mm DC plug. (Also the outside of the barrel connector is the negative - inside positive - should be the case with most adaptors).

Ok, I did find one but I cant link to the page ( I'll get told off ) it's the same specs as you posted above Rroff ?

OK hope this works.

Had a previous power brick fail under warranty and replaced. Also had an entire monitor fail and be replaced!
