Watching HD TV on Desktop Screen

My wife & grand daughter want to be able to watch TV on the PC's Computer Screen. The computer is a new HP & is hooked-up to a newer 23" HD LG screen. It operates from of a Linksys Router that's located in another room w/ my computer. I have Directv service & also now have an extra Directv HD Reciever that I'm removing from another room due to an upgrade. They'd like to be able to enjoy watching HD TV on the new LG screen instead of a very old 19" TV that's hooked up now.

Is this doable & how would I go about hooking this all up. Would it need an HDMI cable, ethernet cable, or other cabling...& downloads that are required?

Thx in Advance...!

It depends on 2 things:

1. What type of inputs you have on the monitor. It's unlikely that your DTV receiver has a DVI or VGA output, but it should have HDMI. If your monitor has HDMI input, or you get an HDMI to DVI or VGA converter, then it depends on #2.

2. If the monitor has a switch or menu to change from one input to the other. I have an Acer widescreen monitor whose menu allows me to switch from DVI to VGA which are the only inputs available.

Also, you would most likely have to run sound to your computer input unless your monitor has speakers that recognize the HDMI audio and you actually want to listen through them.

You should give us the model # of the monitor.

It's a 2253 W Model (http://www.frys.com/product/5871753?site=sr:SEARCH:MAIN_RSLT_PG). It does have an HDMI port, & D-Sub, DVI-D ports as well. The computer is plugged in to the D-Sub. I'd assume it's switchable to go between the two menus. There is also a port for headphone/spkrs. Right now, I have 2 external speakers hooked up to the computer. I'm not sure if the monitor has spkrs? The HD Receiver has an HDMI port...

I hooked-up the HD Reciever to the LG screen & I have Directv HD on the screen. However, I have no Audio. I switched the spkr wire from the Computer to the LG, & still no sound! What do I have to do so that I don't have to switch the wires around or what?

You'll need to run an analog feed from the receiver (the red/white RCA connections) to your computer. You'll need an analog to miniplug converter for the computer connections. You can probably pick one up locally if you have an electronics store or Radio Shack. Here's an example of one at Monoprice (http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=666&seq=1&format=2).

I did try running a mini-plug convrtr attached to red/wht RCA's plugs from the Reciever's Audio l/r ports to the blue port in the back of the PC, but still sound? However, the mini-plug converter I used, had only a two-prong tip & not a 3-prong one...like the one you linked me to from Monoprice.

It's either a bad plug or possibly the sound settings. Check to make sure the sound input is correct and that the line-in isn't muted (I've had that happen before).

I went & got a TRS red & white converter cable (3-ring tip) from Radio Shack & plugged it into the Blue Port of the PC & I still have no sound. The Audio sections appear to be open. I do have sound when I'm on the internet. Is The sound supposed to come out of the Desktop spkrs I have...& what is the headphone port for in the back of the LG Screen? :confused:

Which sound settings in the computer?

Try looking at the recording settings for the sound. There you should be able to adjust the input. Could be this is currently turned down very low,or possibly muted. Hope this helps

Right-click on the volume icon in your system tray and select audio properties. See what the default sound setting is in the Audio tab. Then double-click on the same icon and look at the settings for playback and make sure nothing (especially the wave volume, rear input or output or master volume is muted). This will vary some depending on your audio drivers and OS.

This has got to be the source of the problem. I don't know how your monitor speaker system works as I've never had a monitor with speakers, but you may want to check the manual to find out if the HDMI does recognize sound and to hear it you would have to use the headphone jack which actually works the same as the green output jack on your computer for speakers as well as headphones. Try hooking your speakers up to that monitor output and see what happens.

There are no speakers in the Monitor. There's only a port in the back of the screen w/ the headphones logo! When I remove the jack for the desktop speakers & plug it into the back of the screen I get the Audio for Directv but then...there is no Internet audio.

I checked the areas in the Vol Cntrl you told me to, & nothing is muted. There is RealTech Audio HD Audio Manager in the computer that has line-in & line-out choices for the Green & Blue Ports in the back. I've tried all different options, but still...to no avail.

There must be a way to get both the Internet audio & Directv audio to work w/o having to switch the Desktop spkrs jack between the two?

For right now, I'd suggest getting a splitter to have the speakers work off either the monitor or the desktop since you are at least getting sound through the HDMI output from your DTV receiver. I wouldn't think that the DTV receiver wouldn't allow sound output through HDMI and analog at the same time but it wouldn't hurt to check with them. I have all 3 audio outputs (coax, HDMI and analog) working at the same time on my Dish receiver with no problem.

I was hoping someone else might chime in here as I'm at a loss at this point since all I can figure is no analog output from DTV or a problem with the audio settings in Windows. Do you have another source to feed into the desktop audio input to make sure it's working? That would at least narrow it down to the receiver.

From reading the posts it seems as though the receiver is sending audio to the monitor and the monitor is sending analog audio out the headphone jack on the monitor. lsilvest (http://www.highdefforum.com/members/lsilvest.html) may have hit the issue that when the HDMI output is used on the receiver is used the analog is inoperable, although that seems unlikely. If you are able to get audio out of the LG the cheapest thing to do would be to get a second set of PC speakers for the receiver audio.

You could get an audio mixer to put between your current speakers and the LG audio and the PC audio, but that may cost more than a second set of PC speakers.

You should also be able to input audio into the sound card like lsilvest (http://www.highdefforum.com/members/lsilvest.html) was trying to help you with. What sound card do you have?

After another trip to Radio-Shack, I went w/ lsilvest's splitter suggestion for an easy fix. I do have Audio from both when switching Menus, but there is a considerable Volume loss when on the internet. Directv's Audio is OK...

What sound card do you have?

I have no idea? I'm not that comptr literate...Whichever one it is, I'm sure it could be improved!

I appreciate everyone's help...esp lsilvest's, for taking time to try & work this through w/ me!
