Can 2.1 pc speakers work thru headphone jacks?

Yes. The monitor most likely connected via a VGA port and cable, which does not carry sound. Only exception to this is if your monitor is connected to an HDMI port, which carries video and sound. Your VGA monitor should have an audio input port and you should have an audio out jack in rear of the PC; sometimes on the front, not to be confused with headphone jack. A monitor speaker will not work with headphones plugged in, like most receivers. Good luck

Hook up a computer to it. The tv could have an hdmi connector or monitor connector (check the back of the television to see which type of connectors you have available) so just plug a cable in from your pc to the tv.

For sound, a simple computer cable plugs into the headphone jack of the computer to the back of the television. If you have a PC, you may have a series of connectors for stereo surround sound systems (like a sound card). I use a simple jack that plugs into the headphone jack (stereo speaker jack) and also plugs into the pc audio in port on the tv. Now I just select the input (pc) from the sony menu and select the option for sound input and voila. As long as the pc is connected to the internet, your tv is your new monitor.

if you want audio as well, it will depend on what kind of audio connection your tv has next to the VGA (computer monitor) connection. If it looks like the normal RCA audio, (red and white plugs) you will need to get a male headphone jack (to plug into your computer headphone or speaker out jack) to stereo RCA cable so you would have a headphone jack on one side of the cable and a red and white plug on the other side. Now if your TV just has what look like a headphone jack next to the VGA (computer monitor plug) you will need to buy a male to male stereo headphone jack cable. for both of these, just make sure the cable you get it long enough, or buy an extension.

TRY USEING A REGULAR HEAD PHONE JACK TO HEADPHONE JACK IF AVAILIBLE

There is no audio output on that monitor. So decoding the HDMI into analog is out. However, the simple fix is to plug your speakers or headphones into the green 3.5mm headphone jack on the back of your computer, and change the default audio device in windows. You can use both audio cards at once for different tasks, such as having someones voice come over your HDMI cable on the monitor, while listening to music on the audio out of your computer.

If you need any help setting the audio card, let me know.

Hello,

The only computer (or laptop) connection that carries both video and sound is HDMI. If you do not have a HDMI/DVI connector on the back of your computer, then you will have to use the VGA-composite or s-video connectors to display your PC's output on an external monitor like an LCD TV.

On both my HP and Dell laptops the display settings (Start/Control Panel/Personalize/Display Settings) allow two modes - single or dual monitor mode. Single monitor mode allows me to switch between any one of three possible video outputs - VGA-composite, S-Video or laptop screen, or a split-desktop (display spread over two separate monitors). Dual monitor mode allows the same display on any two of three possible video outputs.

Switching is performed using the fn keys on the keyboard (fn key plus the F2, F8, etc. function key with the display marking). You guys use single monitor mode until you figure out what your are doing. Select VGA-composite or S-Video.

Non-HDMI sound to your TV monitor or sound system must be obtained from your laptop's Headphone or S/PDIF jacks. Headphone is stereo and S/PDIF is 5.1 surround sound. Headphone is electrical, but S/PDIF may be electrical or optical (laser light). You must set the sound jack that you intend to use as the default on the PC control panel (Start/Control Panel/Sound).

None of these connectors is two-way in the context of an LCD monitor - your PC cannot record a TV picture or sound from the external monitor. To accomplish this you must purchase a video converter box that converts cable TV or video + sound inputs to USB format usable by your laptop. Do this and you can turn your laptop into a Tivo recorder/DVD burner using Beyond TV, Sage TV or a variety of other software packages.
Please let me know if you have any further questions or concerns.
Thanks.

The Jack which you found nearby the HDMi is a Input jack. you can get a output from your Computer's Audio out to to this input jack the speakers integrated with the moniter make sound. here there is no chance to plug your headphone. if you want you can plug your headphone in the front jack of your computer

Is the problem that you're using a single HDMI cable to connect your Xbox to your TV? If so, this Turtle Beach article should help... ________________________________________
HDMI and Connecting Ear Force Xbox Headphones
The current Microsoft Xbox 360 series of gaming consoles allow the use of HDMI cables for simpler hookup to home theater systems and Hi-Definition televisions (HDTV).
The Xbox 360 Elite (the black one) comes with two additional cables, an HDMI cable and a separate AUDIO cable that provides a pair of RCA jacks (red and white) and an optical digital audio output (S/PDIF Out). With this cable package, you can easily connect any of our X-series headsets and an HDMI-connected television at the same time.
This Xbox 360 HDMI Cable package is available as an extra-cost option from Microsoft: http://www.xbox.com/en-US/hardware/x/xbox360hdmiavcable/
Here's a more in-depth explanation of the Xbox 360 HDMI Cable and how it works: http://support.microsoft.com/kb/937899?sd=xbox
[NOTE 1:] The standard Xbox models do not come equipped with this cable set. The HD cable they have obscures the HDMI connector, so that the two sockets cannot be used at the same time. If you only have this stock HD connector (component video, composite video, stereo analog audio and optical digital audio connectors), then you will not be able to use the HDMI connector at the same time.
In order to use both sockets at the same time (HDMI and A/V) you'll need to purchase the Xbox 360 HDMI Cable package described above.
[NOTE 2:] The current Xbox 360 Elite Holiday Edition (Fall 2009) does not come with the HDMI Cable set.
___________________________________________________________________
Some companies make aftermarket HDMI cables for use with the Xbox 360, but these may not provide the dual RCA jacks that carry the 2- channel analog audio necessary for hookup of the anlog-only Ear Force X-series headsets. If this is what you have, you may need to find another way to connect your Ear Force X-series headset.
The TOSLINK digitally-connected X-series headsets can be always be connected using optical digital "Toslink" connections (and that's the best way to use them!).
___________________________________________________________________
The oldest white-and-gray Xbox 360 models DO NOT have an HDMI port. With this particular (obsolete) model, you cannot use HDMI connections, but you can use any of our X-series headsets.
Current Xbox 360 models all have separate HDMI and A/V ports ("sockets") on their back panels.

Here are some suggestions for alternative connection schemes:
XBOX 360 AUDIO PLAYS THROUGH TELEVISION SET:
For X4 and X41: Your best bet would be to connect the Xbox optical digital audio out to the X4 transmitter's optical digital input. Then connect the X4 optical digital output to the optical digital audio input on your HDTV or home theater amplifier.
[NOTE:] Some HDTV systems have an optical digital audio output that will not transmit Dolby Digital/DTS encoded digital audio, only stereo PCM audio will be passed. In this case, you must connect as above.
For X2, X3 and X31: You can use the Headphones jack or the Audio Out jacks on your TV to connect to the Audio In jack on the Transmitter.
For X1 and X11: You can use the Headphones jack or the Audio Out jacks on your TV (if available) to connect to the headset's analog Audio Input.

NOTE: Please make sure your TV has Audio Out jacks. Some TV's only have Audio In jacks.
Audio In jacks only accept incoming audio signal; they do not send audio signal out. If no audio signal is being sent to the headset, no sound will play from the headset.
___________________________________________________________________
You may need to purchase a suitable adapter cable in order to connect the TV audio output(s) to the Ear Force X-series headset's transmitter or Audio Input plug.
- Connect the HDMI cable so that the Xbox 360 plays its audio through the TV.
- For X1, adjust the Dashboard > Settings > System > Voice in the Xbox 360 so that the talkback and game sounds are played together (Play Through Speakers). - For X3, X31, X4 and X41, you should set this to Play Through Headset.
__________________________________________________________________
XBOX 360 AUDIO PLAYS THROUGH HOME THEATER RECEIVER (except X4 and X41): This is exactly the same as the above, except that you will use the receiver's Headphones output jack to connect to the Audio In on the Ear Force Xbox-compatible headset's Transmitter (X2, X3, X31) or the green Audio Input plug (X1).
- You may need to obtain a shielded audio cable with 1/4" stereo phone plug to 1/8" stereo mini-phone plug ends. The 1/4" phone plug goes to the receiver's Headphones jack, while the 1/8" mini-phone plug goes to the Audio In on the Ear Force Transmit- ter (X2, X3, X31) or Audio Input plug (X1).
- Adjust the Dashboard > Personal Settings in the Xbox 360 so that the talkback and game sounds are played together (Play Through Both). For X3 and X31, you may also set this to Play Through Headset.

does your tv not have an audio out, if so, you could turn the tv's internal speakers off and just use the audio out jacks instead.

There are no speakers built into this monitor. You will have to purchase speakers in order to get sound.
