Acer EB321 HQU Monitors
I have a pair of Acer EB321 HQU monitors; one is an EB321 (on DisplayPort) and the other is an EB321-C (on HDMI).
They are both a pain for waking up after sleep as they spend a long time seeking an input to use, even though there is exactly one input connected to them. What I want them to do, and I am sure what most people want, is for them to use the same input they were using when they went to sleep! My screens go to sleep far more frequently than they get new cables connected to them!
I have searched this many times, there are complaints on Acer's website and all over Reddit, StackOverflow etc, I could not find an answer. Now I seem to have found the answer - or
at least most of the answer.
So I share it here for fellow-sufferers.
I had this problem with my Debian GNU/Linux PC, but have now started sharing these displays with two
Linux and two Windows PCs using a KVM to switch between them. I have a solution which works for three
of these four devices, and it is this:
Set the QuickStart Mode to "On" and while tomshardware says it consumes a little more power in standby, it certainly does seem to fix the problem I have been having.
It worked better on the Windows 11 PC when I installed the Windows drivers from Acer. Linux worked better straight away.
The fourth PC on my KVM is locked-down by my employer, so I have requested for this driver to be installed onto that PC, and then I hope to be rid of this constant input-seeking for good.
The downside for this fourth PC is that having applied these settings to the monitors and installed the drivers to the other machines, my EB321 HQU-C monitor (on an HDMI input) doesn't wake up at all for that PC unless I disconnect the USB-C docking device that it is connected to. That is a pain, but that is also the PC that I use the least, and I get fast wake-up and KVM switching between the other three devices, so I am happy to wait for the driver to be installed on that final PC.
