New Iiyama Monitor Not Being Recognised Over HDMI

radderfire · 6 Dec 2021 at 14:54

Hey Guys

I bought a new Iiyama ProLite XB3288UHSU 31.5" monitor. I am connecting it via HDMI to my Windows 10 laptop. The only way I can get the monitor to be recognised is to switch it on and connect the HDMI cable to my laptop as the monitor is starting up (displaying the Iiyama logo). If I don't make this connection within approx 20s, the monitor will go into standby mode, and then connecting the HDMI cable does nothing.

If the laptop goes into power standby, then when it wakes the monitor will not wake, so I've just had to switch standby mode on the laptop off, but this is not ideal.

I've had a look through all the menu options on the monitor, but there doesn't appear to be any power options that can be changed to make it work. There is an Eco mode, but that is off.

I've contacted Iiyama support a few days ago but they have not got back to me yet.

Does anyone know if this can be fixed?

Thanks

Still looking at this:

The monitor only works if I connect it to the (switched on) laptop as the monitor is starting up and displaying its Iiyama startup logo.

If the laptop goes into standby, then the monitor will go off, but when the laptop is powered back on, the monitor does not wake.

Does this look like a software issue on the monitor? I am thinking the monitor has a deep (quickly activated) standby mode, and the software is faulty for waking it.

Can anyone shed any light?

Chipset and gpu drivers up to date on the laptop ?

Try manually selecting the display input on the monitor (usually auto by default), just to see if it clears (could be some weirdness due to the monitors power management when using auto input).

Thanks for the reply. Yes, I tried this, manually setting the input as HDMI1 and HDMI2, but still the same problem, i.e. the monitor only ever gets recognised if I connect the cable as the monitor is starting up. It seems to me that this is more likely to be a problem with the monitor software, because it can make a connection, but only as it is starting up. However, I guess it could be either the monitor or the laptop.

I don't know how additional displays work with laptops specifically, but if you start up the laptop with the screen connected(or even connect the screen after it's on), does Windows show the monitor as being connected? (under display settings) It might be quite normal for the secondary screen to remain off until you've told windows what to do with that display, extend or duplicate.

In display settings, it would show that a second monitor has been connected, i.e. that the monitor exists, but if you click the identify button, it does not identify it (so you just see a 1 on the laptop screen, but it does not show a 2 on the external monitor as it should do).

It seems the monitor cannot be identified unless it is connected to the laptop via HDMI as the monitor is starting up. This makes me think it is a fault with the monitor software. The monitor will go into standby after approx 10s if the cable is not connected, i.e. very quickly.

If the monitor is present in Display Settings, then it is being detected by Windows. The Identify function will only work for monitors that the desktop is displaying on.

What is "Multiple Displays" set to?

What do you mean by "identified" here - as above, Windows knows about your monitor; you just need to extend the desktop to it.

Until you've instructed windows what to do with that screen it won't initialise, extend or duplicate (the setting under Multiple Displays as VersionMonkey mentioned). If the screen is connected during startup it will usually duplicate (that's what my system does pre-windows startup), but Windows will turn off the screen once Windows starts to load, that's quite normal, until you tell Windows what to do with it (Extend - make it an additional display, or Duplicate - clone the main screen).

Windows+P keys to choose the output should work, I probably have 100+ laptops that connect to various IWB displays, either touchscreen or projectors. This is a once only setting, there should not be any need to do it again..
