I’m in the process of setting up my laptop to replace my old desktop computer. Everything else has gone smoothly, but this one has me stumped.
On my old desktop (running Windows 7), I had an HDMI cable going directly from the video card to the TV. No special setup was required, and I simply had to use the “Input” button on the TV remote to change the TV to “HDMI3” and I could see what was on the computer monitor. I could even get the computer’s sound to play on the TV if I changed the default sound device. The only time the “HDMI3” input choice was grayed out was when the computer was off.
But with my new setup for the laptop (running Windows 10), I’ve plugged the same HDMI cable into the docking station, but the TV doesn’t let me change the input to “HDMI3” - it’s always grayed out.
I also have my regular monitor now hooked up to the docking station, using the DVI port, and that works fine.
Docking Station: Plugable DisplayLink UD-3900 (brand new!)
Laptop: Toshiba Sattelite C55-C5241, Windows 10
TV Set: LG 42LK520, 1080p resolution
So, is it possible to get this working? It’s annoying that it works with the old setup but not with the new. And if you need any more details, or for me to test out a few ideas, please let me know. I’m happy to participate in troubleshooting.
Thanks for your help.
