Although the current generation Samsung TVs will no longer offer a VGA port, there are two other ways to connect your PC or Mac to a Samsung TV for monitor functionality: HDMI to HDMI or HDMI to VGA/DVI/Displayport.
That said, the Samsung TVs do not offer wireless or networked monitor capabilities.
Please note, in the computer's operating system, you will need to set the display settings to either clone or extended view and set the computer’s resolution to match that of the maximum resolution of the TV in order to view your computer’s desktop on the TV.

If your computer offers HDMI out, I would highly suggest using this connection, since it is a basic plug-n-play connection (meaning almost no adjustment is needed on the TV or PC).

HDMI to VGA/DVI/Displayport is almost the same as straight HDMI, but in this case, you will want to connect the DVI end of the cable to the computer (if available) and the HDMI into the TV. This is also considered a plug-n-play connection.

Unless otherwise specified by your computer manufacturer, you will need to connect the computer's audio to the TV with a separate cable (3.5mm jack cable from the PC’s audio output to the TV’s DVI/HDMI Audio input), since most computers do not support audio over HDMI, VGA or DVI.

Thank you for the opportunity to assist you,
