S243HL “No Signal” detected connecting to either HDMI port
Hi there, I have a S243HL monitor and I’m getting a “no signal” message when I try to connect it to my laptop via either HDMI or DVI. I’ve tried connecting to other laptops with the same problem. Any idea why? I also can’t get the on screen menu to display. It seems like the monitor just doesn’t detect a connection and goes into sleep mode.

Is it possible this monitor isn’t compatible with windows 10 or something crazy like that? I tried searching for drivers for this model number on the Acer website but could only find windows vista drivers haha. That’s the set of drivers the Acer Twitter team referred me to as well, then they referred me here to try to find help.When I connect it via HDMI to my computer the monitor wakes from sleep mode (amber light to blue light along the buttons) only to display a “No Signal” message on the monitor, then the monitor goes back to sleep mode.0

Is there a chance the laptop has the external display disabled in the BIOS? Since the monitor is showing you the no signal message the display itself seems to be working...

The weird thing is the monitor seems to work fine if I connect it via HDMI to my cable box. It just won’t connect to my laptop. And my laptop connects to other external monitors just fine. I use a different external monitor every day. And it’s not the HDMI cable.
The previous owner was using it with Windows 10, so I haven’t given up hope yet, but I’m stumped.0 -

I just responded to a previous post with a bunch of other things I’ve tried too. It’s really odd. The monitor definitely seems to work, and my laptop definitely works, but it won’t connect to display video from my laptop.
It won’t work with another laptop we tried that belongs to a friend of mine either, so it seems it’s not just my computer that doesn’t work with it. But the previous owner, also a Windows 10 user, seemed to have had it working.0 -
Yes, it wouldn't be a driver or W10 issue, and it's not a resolution mismatch. When you test with a different monitor, are you also using a different cable?

The friend of mine that tested tried to connect to their laptop using the same cable, only their machine does have an HDMI port and they directly connected - and they had the exact same problem as me. No signal. And I don’t think it would be a BIOS issue on their machine either as they also regularly connect to a different monitor and it works fine.0 -
DP to HDMI and HDMI to DP adapters are very different. A DP on the laptop connecting to an HDMI on the monitor requires a DP to HDMI, an HDMI to DP will not work... Any chance you just have the wrong cable?

Doesn’t that narrow it down to either an Acer driver issue or some kind of compatibility issue?0 -
I can't see any way it would be a drivers or Windows issue. The S243HL supports 1920x1080@60Hz which is about as standard as you get these days. There are no drivers required, the connection is described over the interface using plug and play. I could see corrupted firmware on the monitor potentially telling the computer it supports some weird resolution, but that doesn't explain the TV working or why Windows wouldn't see that there's a monitor there...

I can't image it being power, those ports pretty much just have signals. Firmware updates aren't possible by the end user, a monitor typically has to be shipped to the repair depot for one. Which is why they seldom provide firmware updates...

To get my newest Acer monitor to work with an older laptop, I had to set the resolution lower than the laptop display and set it to 50hz. I had the same exact issue as you for several days until an option finally popped up in the Intel HD control panel settings allowed me to go lower than 60hz.1

Maybe it needs a newer driver for you to be able to change the refresh rate lower. I don't see any newer than the one from 2009. Perhaps this program might be able to find a driver for your external display adapter.
