PiP shouldn't matter when regarding attaching your computer to your television.

If you have the appropriate cables and ports, such as an HDMI, then you should be able to connect the two together.

I am currently using a television as my main monitor. All I had to do was connect the HDMI cable to each and select the correct input on my TV.

If you do not have an HDMI port on your computer, there should be adapters available.

At the end of the day, the only difference between a television and a monitor is that a television has tuners in it.

When using PS3 on RCA D52W19 TV, the screen does not fit ( it is zoomed and off-center) in 1080i resolution.


hello!
Have you tried to toggle "format" or "screen size"? On those sets non HD and HD settings could be adjusted separately. Try that, first. If no luck, try similar settings on PS3. I bet, you will be able to match screen format there, as well. To me it looks, like picture formats are mismatched. Also: try to use "component" cables, instead of DVI adapter cable, if nothing works.
good luck,
Alex.

I can not get the pic on the tv


Hi,

If this is a new DVD player that you have connected to your TV,
It can be connected in three different ways using three different cables.
only one type is required
  • one way is using a RCA cable, which is a yellow plug on the DVD and TV
  • another way is a S video cable, which is round and has multiple pins.
  • and the third way is a HDMI cable which is rectangular with multiple pins
Which every one you use, for eg if you use a HDMI cable to connect it up to the TV you will need to select HDMI on your TV via the remote and press TV/AV until you get to HDMI.

Also most DVD players have a menu to set up, which you can select what type of output picture lead you are using, Eg. HDMI or Composite = RCA or S Video.
I have enclosed a picture to determine which lead you are using.
If your TV is HDMI then this will give the best picture quality then S Video then composite RCA.

I hope this helps you

I tried hooking up my laptop to my 37lh20 tv. I connected the avi to the pc input and an audio cable fro the headset jack on the tv. If I put the tv input on rgb pc I get the picture but no sound and if...


Unless you hook HDMI to HDMI, you won't carry sound across the HDMI cable. If you're using a VGA to HDMI converter, you'll get the picture but no sound.

I have a feeling the headset jack on the TV is an output rather than an input. Most TVs accept HDMI, RCA, or a digital audio input (either coaxial or optical). Unless you have a S/PDIF optical output from your laptop (and you obviously don't have an HDMI output), then your only other choice is likely to get a cable that splits a 1/8" headset type connector into two RCA plugs that you'll plug into an AUDIO IN input on your TV.

Turned on the tv and i have no picture just sound...


Most likely fault is the backlight inverter board. May be a simple fix due to bad capacitors or may require a new inverter board.
You can check that the LCD screen is still working by shining a torch on the screen and looking carefully for a dim picture. Try putting the menu on so that you have a known static image to look for.

If I tap the rca jacks in the back the screen gets distorted


You need a hdmi connector from your tv source to the TV. RCA connectors don't have the capability for HD signal transmission. You can use them for a connection but the picture will be fuzzy if trying to watch HD signal. Check your cable/dish box to see if there is a hdmi output. If so, buy a hdmi cable & that should solve your problems.
