Hey I suspect it’s the cable (the standards are different or it can’t handle 240hz) but just ensure you have all the latest drivers installed and also if you could try a different cable/port and see if the issue persists.
Hope this helps!
Hey guys,
I recently got a Dell S2721QS monitor to hook up to my Acer Aspire Laptop Running Windows 11.
When I got the monitor, I plugged it in to my computer using the included hdmi cable and I noticed that it said no signal on the monitor but my laptop was recognizing the monitor just fine...
