Question about Vizio P42HD Television

When I connect HDMI from a Time Warner DVR to my Vizio thru a DVI/HDMI adapter, I get no sound. I can only get sound if I use Component input (RGB+ audio R&L). Is this a DVR issue or a Vizio issue?

Use the Time Warner remote and hit the settings button twice. Scroll down to "audio: digital out" and select HDMI. That solved it for me.

The only issue I have now is that I also have component sound outputs going from the cable box to a receiver. When I turn off the TV while the HDMI cable is hooked up to both the box and the tv the sound goes out to the receiver...

How to turn on rgb from lap top to tv.


In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

I have a HP m7570n. How do I use a flat screen tv as a monitor


This depends on the TV's available inputs. The Pavilion m7570n has only a VGA output in the standard configuration.

Thus if the TV has a VGA port, turn off the computer and the TV. Then connect a standard VGA (RGB or D-sub 15-pin) m/m cable between the computer and the TV. To use the TV speakers, connect a 3.5 mm audio patch cable between the computers Line-out (green speaker port) to the VGA audio in. Turn on the TV and set the input to VGA (with the Source or Input button on the remote or the TV). Then turn on the computer. Windows XP should find the correct resolution to work with the TV. (If you turn on the TV after turning on the computer, you may get an unsupported signal. Press Ctrl-Alt-Del twice to restart the computer.) If it doesn't work, you may need to connect a different monitor and set the computer to a low resolution before connecting the TV and the computer.

If the TV only has composite or component video inputs, you will need a VGA to video converter (http://www.svideo.com/pctocomponent.html for example). A VGA to component cable will not work; those are for projectors that read an RGB input. TVs interpret YPbPr.

If you have added a video graphics card, you may have an HDMI and/or DVI port(s) on the card. In that case, check the specs of the TV. Some TVs will support HDMI or DVI-HDMI inputs from a computer. Others will not (since computer video signals are not the same as the signal from a set-top box). If you use a DVI-HDMI connector, make sure to use the HDMI port labeled for DVI and connect the audio cable as with the VGA connection. If you use an HDMI connection, you may need to set the sound properties to that of the HDMI port. (Find the control panel item for sound (under Hardware) and then select Manage Audio Devices. Set the Playback properties. If it doesn't work, use an audio patch cable.) Some TVs have RCA audio inputs for the HDMI-DVI connector. In that case, you will need a female 3.5 mm to RCA M/M adapter (if you use a 3.5 mm patch cable). There is a similar device if you want to use an RCA audio cable. You may need to enable the video ports on the graphics card before swapping monitors.

Some video cards have a TV out. In that case, connect the appropriate connector (should come with the video card). Then connect to the component, composite or S-video input on the TV.

Again turn off the TV and the computer before making any connections.

You will probably need to provide your own cables for must of these connection options.

I hope this helps.

How do you hook up the tv thru dvi out with a sony pcv-rs620g


There are several ways to do this. The two best are:

1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

Currently, I am using option 2 for my own use.

In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.

How to eliminate error screen:"your tv does not allow display of this program through the dvi input source. please chose another tv input source."


"cable box to tv is hdmi cable"

Everything I've read on the web says cable box to tv connection must also use component (rgb) cables. The error is coming from the cable box (STB). All the Scientific Atlanta (SA) cable boxes seem have this Digital Rights Management (DRM) bug and the only way to be totally rid of the error is to replace the digital connection from box to the TV with an analog connection.

Hook up a lg blueray player to mitsubishi medallion 65"


Yes, there is an adapter which will take the hdmi output of the blue-ray and convert it to dvi. You will also need to connect the blue-ray audio out (rca jacks) since the hdmi is both audio and video (digital) and the dvi is video only.

Connecting an LCD TV to a computer to use as TV and Comp. Monitor.


Im no expert on the subject, but I use my L37 for a monitor, and use just the vga adapter. It works good as a monitor, and both dvds and my hdtv wonder tuner card look great through the vga connection. They do make adapters for dvi to hdmi. Although, hdmi also carries sound, but you wont get that out of your dvi output from your card. So you might not have sound when using that connection, as your tv may not look to the headphone type jack used for sound imput from your computer when you select the hdmi source on it. If you have speakers already connected to your computer you may not care. Also if you have a 720 p Vizio, 1366x768 is the highest resolution you are going to get out of it anyway, if I'm not mistaken. I'm Not sure why you would need 2 connectios to the same monitor either. I posted 1 link below because they had several dvi to hdmi adapters. Hope that helps.

HDMI Cable?


Hi CrysR,

Although you may not be able to locate a cable with one HDMI male end and one USB male end, it is possible you may find a solution with an adapter.

I recommend looking for an adapter that will accept USB input and output to either HDMI or DVI. If you only locate DVI, you can then add a DVI to HDMI adapter at the end.

Be aware with these extra pieces and signal transfers included, it may degrade the quality of your picture.

Thank you,
Jason,

Need diagram to connect Motorola DVR, Panasonic DMR-E recorder, A/V Receiver, and HDTV


Your not going to be able to connect in series (not sure if thats your goal) since your limited by the type of connections you can use. Your receiver is going to have to be switched depeneding on what source you want to listen too. DVR, DVD, etc. HDMI is going to important for your TV connection. Radio Shack has cheap HDMI cables.
So... connect HDMI from DVR to HDTV this will give you sound and picture to TV. Connect DVR optical or coaxial ( RCA if you dont care about surround) to Receiver to give you DVR sound thru Receiver input.
Connect DVD to receiver via optical/coaxial/rca for DVD sound thru receiver (again RCA is not recommended for surround).
Connect Component video to HDTV(or HDMI if TV has second HDMI input) to give you video from DVD.
Connect Yellow video or S-video from DVR to DVD recorder input to allow recording from DVR. Also connect red/white audio to (same) DVD input.
That should cover it.
