Samsung Smart TV as VGA monitor?

Tried to ask a question using Samsung Technical Support email but gave up when got nowhere.
FYI This is what I used http://www.samsung.com/us/support/email/product/

Wanted to ask if I can use a standard PC VGA cable to connect my Windows XP PC to a Samsung Smart TV and use it as a monitor?

Also if anyone has the email for Samsung Technical Support would be interested.

Did a forum search to check if anyone had posted something similar but got nothing.

Thanks

Ken
 
My reason for asking this question was told "C-Series ex-link is on TTL-Level (0V to +5V) while your PC operates at RS232-Level (-12V to +12V) so your cable has to have at least some kind of Voltage-level shifter."

Hard for me to believe that Samsung would make Smart TV that could be damaged if someone used a standard VGA cable to connect it to a PC.

But you never can tell and would rather be safe and ask.

Thanks

Ken

Not all sub-D connectors are created serial ports ;-)

The VGA connector on a PC is a female 15-pin sub-D carrying TTL levels.

If your PC has a 9-pin male sub-D, that would most likely be a COM port
carrying RS232-level signals. Sending video over this port is a no-no.

Cheers!

Correction: the VGA connector carries both analog and digital (TTL).
The color lines RGB carry analog signals (0.7V p-p).

If your PC has a connector that looks like this
http://en.wikipedia.org/wiki/VGA_connector#mediaviewer/File:SVGA_port.jpg
, and the TV has the same connector on the back, then you should be
able to use a cable with this connector
http://en.wikipedia.org/wiki/VGA_connector#mediaviewer/File:Male_VGA_connector.jpg
on both ends to connect the PC to the TV.

You will probably have to use the TV remote control, or the buttons on
the front panel of the TV (if it has them), to switch to the "PC" or
"VGA" input, as shown on the on-screen menu on the TV. The TV probably
won't automatically switch to that input when you turn on the PC or when
you plug in the VGA cable.

If the PC is putting out a picture that is smaller than the capability
of the TV (which is usually 1920 x 1080), the TV will probably scale up
the picture the PC is putting out so that it fills the TV screen. This
may make the picture on the TV look stretched or fuzzy. If you set the
PC to display 1920 x 1080, you will get a better picture on the TV.

If the PC (or the video card in the PC) is very old, it may not be
possible to set it that high. In that case, set it as high as you can,
and look in the TV menus (remote control or front panel buttons) for
options that control the scaling. You probably won't be able to get
the picture to fill the whole TV screen, but you can get it to look
less stretched or fuzzy.

If the PC is putting out some goofball signal that the TV cannot handle,
you will probably get a message like "Out of range" or "No signal" on
the TV screen. You may get a distorted picture on the TV for a few
seconds before you get that message. If you get that message, just
unplug the VGA cable from the TV, and you shouldn't hurt anything.

In that case you still have some options to explore:
- some cards/drivers have options to create custom resolutions in their control panel advanced settings.

- some cards/drivers read the resolutions and refresh rates supported by the connected monitor through the EDID bus and make them available. You must use a VGA cable that connects the EDID pins (not all do).

- you can use WinModelines to add custom resolutions if your card driver is supported. Most ATI and NVidia and some Matrox.

The modeline for 1920x1080 at 60Hz would be:
Modeline "1920x1080 67,1KHz 60,0Hz" 172.798 1920 2043 2249 2576 1080 1081 1084 1118 -hsync -vsync

You're question, split over 2 messages, is really quite vague.

Either there's a VGA connector on the tv set (and it says "VGA", or there
isn't. Just because there's a connector of the right size and number of
pins doesn't mean it's VGA.

On the other hand, you may be asking something else.

Everyone,

Thanks for the comments.

If someone tells me how I will post a photo of the Samsung Smart TV VGA plug.

You can't post it directly in the newsgroup. Put it on a photo hosting
site like Imgur (you don't need an account there to do this) and post
the URL here.

If it doesn't look like the connector I posted earlier (three rows with
5 sockets each), then it's probably not a VGA connector.

Matt,

Thanks for the instructions!

Wanted everyone to see that the VGA connector has a label "PC IN"

Uploaded the photo and here are the links

If it is marked PC IN. it most surely is a VGA-connecter you can plug
an ordinary VGA-cable in.

But if your pc has a HDMI-output, you will get better quality and sound
in one cable.

The connector labeled "PC IN" is a standard VGA connector. You can
connect your PC to this TV set using a standard VGA cable, with male
connectors on both ends of the cable.

If you also want your computer audio to come through the TV speakers,
you can also use a standard audio cable, with 1/8" (3.5mm) stereo plugs
on each end. One end plugs into the line-out jack on your PC (usually
green), and the other end plugs into the "PC/DVI AUDIO IN" jack on your
TV. You don't have to do this if all you care about is the picture.
