PG32UCDP - Power Consumption issue

[tom1701]

Dear Asus,

it seems that PG32UCDP in standby does not sleep at all. I have checked on the power meter and on my UPS that while device is in standby it actually drains a lot more than 0.3W or 0.5 W.
In fact, I have observed that device is taking between 18W to 45W every 2-3 seconds. I have tested multiple PG32UCDP, and all behaves the same. Power consumption goes according to spec only when device is running in power sawing mode which does impact other features like brightness.

My device setting/state:

- standard power mode
- firmware MCM103

- OLED care enabled

Will this problem be fixed or should I return the unit?

I forgot to mention power indicator logo is solid ORANGE.

Have you tried disabling aura sync, then disabling USB HUB availability during stand-by?

[tom1701]

Yes, USB HUB is off during standby and no aura sync enabled for me.
I purchased NEW power meter and in standard power mode it shows 9W-10W now.
In power saving mode power consumption is as it should. I guess something is wrong with firmware.
This 3rd monitor behaving exactly the same.

I think we can close this topic.
I have done additional tests, and it seems that it is not the monitor but in fact the power adapter which takes 8W - 9W as minimum where there is slightest power draw from the monitor. Old monitor power adapter is behaving the same on 220V power line.
So as per technical documentation it seems statement 0.5W in standby is true, if you measure it on monitor end but not on the power plug itself.

My monitor (PG32UCDM) comes bundled with either of the same two models listed in your monitor's manual. Specifically my unit shipped with the ADP-280BB B and power draw after the 3rd click on the power button from ON state (which should be comparable to stand-by without hub/rgb), it draws 0.5W from the wall socket

[tom1701]

For me it is actually 2 clicks which power down the monitor (3rd would start monitor again in normal state). In that state power consumption is indeed 0.5W. in standard Standby mode solid "ORANGE" logo on wall socket it takes 8W - 9W.

Interesting.

If it's not too much curiosity on my part, how did you measure power usage from the DC side only?

[tom1701]

I measure it on the power Socket as I lack more professional equipment 😉
For the socket itself I am having inline power meter connected only to monitor so I can see the power draw in various monitor states.
