For reasons I don’t really understand, Windows* seems to ignore the HDMI* port when you plug something in, so we’ll have to power it up and tell the computer it’s fine to send a signal out on the line.
That’s done by going into Control Panels and selecting “Adjust screen resolution”. On that window you’ll see that it shows there are two different displays, but one of them will be disabled.
To remedy this, click on the second monitor, then choose “Extend the desktop onto this monitor” and click “Apply”.
The HDTV screen should come to life and show you a Windows desktop background photograph.
If it doesn’t, try again.
Sometimes you have to select this more than once.
It is recommend that you now tweak the resolution on the second screen to be at least 1100 x 650, depending on what options you have. It mostly works out with 1184 x 666.
The goal is to have the background photo spread across the entire TV screen. Now make sure you have the sound unmuted and at a reasonable volume on your computer and on the TV and let’s get some content on the screen!
