SOURCE: Laptop computer connected to projector.

When the projector displays the background image and the lcd displays the desktop as normal you can drag the open windows to the left or right and display them on the projector. it sounds like this laptop has an internal video card. If you right click on the desktop it might give you options to configure the display settings for the video card. Not sure how you will get to it if it does not show up on the right click menu. Probably through the start menu or in the control panel there should be somewhere to change the settings for the video card. This will no be under the display settings though.

But once you find your dual display options you will be able to change it to make both displays the same

Hi

Make sure your TV does indeed support the resolutions you are trying to use. Some low quality HDMI cables can also be troublesome in higher resolution so try one you are sure to work.

Regarding to the desktop only being extended when using the RGB cables, try bringing up the desktop properties window, select the TV as the primary monitor and select "Use this monitor as Primary monitor". You might have to drag the windows Taskbar over to the other monitor, just rightclick the taskbar, uncheck "Lock the Taskbar" and drag it over to the other monitor.



Hope you find this solution helpful, and please rate it if you do so..

best regards,


Karl

You need to press the FUNCTION key or FN key. While holding down that key, Press one of the F keys on top. The F key will have a picture of a monitor on it. Usually F4 or F10 key. So hold down the FUNCTION key and press that F key. That will display your laptop on the TV. You can press it a few time to switch between your laptop display or both.

How to Connect Laptop to Projector

How to display computer image on TV or projector
How to display a computer image on a TV or projector All modern televisions and projectors have one or more ports which allow them to receive and display an image generated by a computer. Both desktop and laptop computers are capable of connecting to a TV or projector, provided that they have the appropriate cables. The following sections contain instructions for using your TV or projector as a computer monitor. For best results, we recommend reading them in order.
Identifying available connections
Connecting computer and projector or TV
Display using Desktop
Display using Laptop
I don't see an image on my TV screen

Identifying available connections The first step in connecting your computer to a TV or projector is finding an identical port on both machines. Once the matching port has been identified (one that is the same on both your input device and output device), you need the appropriate cable to connect them. This section contains a picture of the back of an Epson projector and its available connection ports; as well as descriptions of each.

HDMI
The HDMI connection is very popular among display electronics. In fact, nearly all modern televisions and projectors feature HDMI ports. Most laptop computers support HDMI and it is becoming more prevalent on both desktop as well; even without a high-end video card. HDMI is quickly becoming the standard for all electronic equipment for its high quality signal and ability to carry both audio and video signals. The image to the right is that of an HDMI cable.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-1.jpg VGA
The VGA connection is the most common among both desktop and laptop computers, is found on most projectors, and some TVs. The VGA cable has a 15-pin connector on each end that plugs into a VGA port on each device. Due to the fact that most televisions do not support VGA, we recommend using HDMI for their wider range of compatibility.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-2.jpg Tip:VGA cabling is universal for devices that support it. For example, the if your desktop monitor that uses a VGA cable it, that same cable can be used by a laptop to connect it to a projector.
Note: If you are using an Apple desktop or laptop you need a VGA adapter to connect a VGA cable to the computer.

DVI
The DVI connection is newer than VGA and it offers a sharper image. Although the DVI port is not shown on the Epson model above, it is still somewhat common for projectors, not so much for televisions. It is mostly found among desktop computers for monitors, but some laptops have DVI connections as well (Apple laptops are more commonly known to support DVI than any other brand of laptop). Since finding DVI on a TV or projector is more difficult, we again recommend using HDMI cables.
Tip: There are special cables that convert from DVI to VGA or DVI to HDMI and vice versa.


find-connect-projector-option-vga-hdmi-zonwsocbr3qazne24mugrpvs-1-3.jpg
Composite Video
The composite video connection is quite common on a TV or projector, but it is nearly nonexistent on modern computers. This connection is the yellow female cable on what is normally a three bundle of red, white, and yellow. The only time you should see this setup is on older video cards for desktop computers.
S-Video
The S-Video connection is also commonly found on TVs and projectors, but solemnly on a desktop or laptop computer. This connection is a small step up from composite video, but is nearing obsolescence.

Connecting computer and projector or TV After you've identified what connections are available on both your computer and TV or projector, you're ready to connect the cables. If the same connections are not available for both the computer and TV or projector, you'll need to purchase a video converter cable that converts one signal into a compatible signal.

Desktop Computers For a desktop, you simply need to plug the cable into the computer and output device. If you don't see an image, you may need to change the display using the following steps.
  1. Press the Windows Key.
  2. Type Adjust screen resolution and press Enter.
  3. Find Display and click the down arrow on the right-hand side of the box.
  4. Select the appropriate output device.
  5. Click Apply then OK.

Laptop Computers If you're connecting a laptop computer to a TV or a projector you'll often need to "send" the video signal to the display device. The key sequence to do this varies depending on the laptop; but usually it's either: Fn + F3, F4, F5, F8, or F9. For example, pressing and holding Fn + F3 at the same time on my laptop sends the video signal to my connected TV instead of the laptop's screen. The corresponding key used with Fn may be labeled as CRT/LCD or have a picture of a monitor on or close to the key. Additional help and information with switching the laptop display can also be found on the link below.
Switching TV inputs Finally, if you're connecting a computer to a TV make sure it has been switched to the correct input. For example, if you connected an HDMI cable to your computer and the "HDMI 2" port on your TV, you'll need to switch to the "HDMI 2" input. This action can be accomplished by pressing the input button on your TV remote until the correct image is displayed.

Link ASUS laptop to Sharp Aquos LCD TV


No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

How to connect dish tv to my laptop? It has inbuilt tv tuner.


Your Lenovo laptop can be hooked up your TV if you have a model that is capable of TV output. Newer models with HDMI ports can easily connect to newer TVs that have HDMI input jacks. For older laptops or TVs, you will need other adapters or cables. The most common of these is an S-video jack, which has a small round connector with several pins arranged in a circle. For S-video connections, you will need to hook up the audio from your laptop to your TV separately.

Things You'll Need

HDMI cable

USB-to-HDMI adapter

OR

S-video cable

Audio cables

HDMI Connection

Turn on your Lenovo laptop and HDMI-enabled TV.

Connect one end of your HDMI cable to the HDMI port on your laptop. Lenovo's IdeaPad series has these ports. If you have a ThinkPad or other Lenovo model, connect a USB-to-HDMI adapter to your HDMI cable, then plug the USB end of the adapter into any USB port.

Press the "FN" and "F7" keys on your keyboard. This will switch the laptop's display to the TV. You can then use your TV screen as a monitor or use the laptop's DVD drive to watch movies on your TV.

S-Video Connection

Turn off your laptop and TV. Connect your S-video cable to the laptop on one end and the TV on the other.

Plug audio cables into your audio out jacks on the laptop. If you do not have stereo audio output, you can use the headphone/speaker jack. Add a splitter adapter to split the sound into stereo instead of mono (single speaker). Plug the other ends of the audio cables into your TV.

Turn on the laptop and let it boot up. Then turn on the TV. Right-click on your desktop screen, then select "Properties."

Click the "Settings" tab, the "Advanced" button, then "ATI displays" or "Display device" or the similarly worded option, depending on your system. It is not the "On screen displays" option in any version.

Click on the option that suits your system, such as "TV" or "LCD." Click "Apply," then "Yes" to confirm, if necessary. Click "OK" to exit. Your display should be visible on the TV screen. If not, try pressing "FN" and "F7" to toggle the display to the external screen.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...


'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:


Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.


Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

Hi, When I connect my Samsung RF711 laptop to my Sanyo LCD-42XR9DA TV HDMI to HDMI, and source the HDMI 1 input and press OK I do not get any laptop display on the TV screen at all. I have spoken to both...


I suspect that the TV can't read the signal from the computer on the HDMI port. You would get a signal from a VGA connection. (Computers send a slightly different signal over HDMI than a DVD or blu-ray player.)

In general, when connecting a TV to a computer, turn off both devices before connecting the video cables. Then turn on the TV and set it to the source (with the no signal message). Then turn on the computer. Next set the computer to output the video on the external video port. (Depending on the laptop, you may need to enable the port in the BIOS. To access the BIOS, press Esc, F1, F2 or F10 repeatedly as you turn on the computer. The key depends on the brand of computer.) Next set the video output in the OS (depends on the OS). For Windows 7, right click on the desktop (anywhere there are no icons or running programs), select Graphics Properties and set the desired monitor choice (laptop monitor, external monitor, both or extended). Click Apply and then confirm this when the display changes. (At least this works for my HP laptop on the VGA port.; my desktop lets me change monitors under Screen Resolution.)

The manual for the TV is available here: http://www.sanyo.com.au/resources/manuals/tvs/lcd42xr9da_im.pdf .

I wish that I had better news for you.

Yah i have a dynex tv and a Asus desktop comp and my tv says no signal when i plug it in i dont know what the problem is


Is the dynex tv unit installed inside the ASUS desktop computer?
The TV receiver needs an antenna/aerial connected to the TV receiver to receive TV signals, without it you will get no or weak signal.
Have you connected an antenna/aerial to the Dynex TV unit?
