What
you will need:
The quick,
cheap and basic way to get a computer to show up on a TV is to plug it in. If
you have a desktop pc, you may be able to use the cable
that you have right now going to your monitor. If you have a notebook computer, you’ll need to buy an
additional cable(s).
Here’s the
common inputs you’ll see:
VGA Cable
This
is the tried and true connector that we have seen on computers, well almost
forever. This is the connector that nearly every HDTV will have. Sure you may
not get the resolution you need, and it can’t play back protected content
(think Blu-Ray movies),
but it is quick and simple to use.
S-Video
Some
computers have it, some don’t – but S-Video is also a
quick and easy way to get the computer screen working on the TV. The nice thing
about S-Video is that it will many times work on standard resolution TVs if you
still have one hanging around (the resolution is not that good, but it’s a nice
way to show off pictures).
DVI
Cable
DVI is
a terrific format to use, not only because it can support very high
resolutions, but also because it can support full resolution HDCP protected
content (High Definition movies such as found with Blu-Ray). Because the signal
is digital (VGA isn’t), you also tend to get a much better looking picture than
you would than with VGA. The cable can cost more, and it doesn’t carry audio
(you’d need a separate audio patch cable for that), however the next
cable on our list does. HDMI Cable
For
hooking a computer to an HDTV, this is definitely the way to go for many people
because it’s one cable that carries both video and audio, it supports HDCP
protected content and high resolutions, and is relatively inexpensive. One
drawback is that while many laptops have an HDMI connector, many desktops do
not – so you’d need to add that port yourself (usually through a video card
upgrade). Wireless
Some companies, such as IOGear
also offer wireless solutions for both video and audio. Wireless tends not to
support the higher resolutions, but can be alot of fun to use.
Tips…
Some common caveats to look out for:
1. You need to go into
your video card “control panel”, use a function key
or go into the video card properties to set up the computer for “dual monitor use” if you have a laptop or are
leaving your main monitor connected if using a desktop. For TV display, most
people just choose to “mirror” the display (same image appears on both
monitors).
2. Unless you are using
HDMI, you’ll need to run a separate audio cable for audio through the TV.
3. The highest resolution
you can display is what can be supported by both the TV and the video card (it
is just like a big monitor after all).
4. For Blu-Ray protected
content, you’d need to set your output to the HDTV only – it will not
usually display on both TV and monitor (you may also need to set the audio out
to SPDIF for Blu-Ray movies to get the audio on the TV as well).
5. Some laptop computers
tend to “lose” the audio capabilities of HDMI when using drivers not designed
for the unit (even if it is a “recommended” update from your computer automatic
updates).
6. You may need to “play”
with the TV’s aspect ratio to make the computers output “fit” properly to the
TV screen.
7. Be sure that you set
the source on your TV to match the input you are using on the computer.
8. Make sure that the
cables are plugged in all the way – it’s really easy for a cable to slip out
“just a little”.

Conclusion
Whether you want to show off some photos
in a slide show or use your Entertainment PC for use as a Blu-Ray player,
hooking up your computer to a HDTV is a great way to use your HDTV to its full
capability. So fire up the PC, plug
it in and let the fun begin!
