Help finding laptop

[Lonman]

I send my one HDMI output (for the singer screen) to 4 screens via a splitter. I do believe you\'ll need to make sure all the tv\'s are on the same setting as far as resolution.
The Hoster screen would remain on the laptop screen. They do make USB video cards - however I do not think it would change the ability to move the Hoster screen to an external monitor along with the singer screen.
