I have had my ASUS laptop (Windows 10) hooked up to the 47" Samsung tv in the living room by HDMI cord several times and its worked fine. But when i try to bring my laptop into my bedroom to hook it up to my 35" Samsung LN-R238W, the tv reads "no signal." There is only one HDMI port on the tv. And when i go into display settings on my laptop to multiple displays, instead of showing 2 separate monitor icons that are numbered 1 and 2, it just shows one icon with 1/2 on it. So I'm not sure what that means.
