Hello
Can you hold down win+R keys, type in mmsys.cpl and press enter, when launched, is the monitor listed? If it is, make sure it is not disabled - you can right click to enable it. And also make sure it is set as default device,
If the monitor is not listed, can you share with me two screenshots please?
- Go to Device Manager > Display Adapters, I would like to see what's listed.
- Please type msinfo32.exe in the search on the taskbar and hit enter, then share a screenshot of the pop up.
I also need to know -
You said you hooked up with old speakers - to where, to the computer or to the monitor? Do the speakers work?
What's the monitor's brand and model?
How do you connect the monitor, for example, HDMI to HDMI, Display port to display porty, any adapter/converter involved?
