Are you sure that the settings aren't stuck on the wrong display I know I always have trouble with which is 1 and which is 2.

I can run Hdmi from my computer directly to my TV with out any converter so it's pretty simple for me.

What happens when you disconnect the computer cable to the TV at the computer end, does the monitor come back on.

I notice that your monitor setting is 1600 by 900 thats pretty low for a Desktop PC can it be set to match the TV which is probably 1080?.

If so what number does it identify as and what happens if you reconnect the TV?

Does the TV show up as a source?

It's hard for me to guess but I'd start by getting it working normally with the monitor make sure your drivers are up to date and then try plug everything back in and tell it to duplicate the display.

I see that your computer has one Hdmi port, I assume that you are using that for your monitor?

If you can't get it to work Amazon has an Hdmi cable splitter for $10.99 you might want to try that and avoid the converter.

You can switch where the output goes with a button and the light will show you where the output is directed.

Make sure that the TV is set to the HDMI from the computer, mine says "HDMi2" so that the computer will recognize it.
Right click on the desktop and select Display Settings.

Find Multiple Displays, click Detect.

If it finds the TV you should see the option to mirror the two displays.

If I click om detect I get a message didn't detect another display.
I have two square 1 and 2
When I click on identify on 1, the number 1 pops up
When I click identify on 2 the number 1 pops ups instead of 2 (here is the problem)
Advanced setting shows display 1 monitor display 2 TV
It appears the problem is that it not detecting 2
In multiple display the options I have : extend these displays
clicking on the arrow: duplicate these displays, show only on 1, show only on 2
no mirror display

I'm just not sure what's going on, If it is showing display 1 and 2 it's seeing both displays what happens if you click on duplicate these displays? I think that is the correct terminology not mirror now that you mention it.

I just discovered that my new computer has 3 display port connections and only one Hdmi port so I had to order a converter myself to connect it to my TV. My old computer had several Hdmi ports. I'm using my Hdmi port for my monitor.

The adapter won't be here until tomorrow I'll know more after I get it and do this myself with my new computer.

But I think that if you are seeing 1 and 2 it's detecting your TV. When you click identify the number 2 should pop up on the TV not on your monitor.
