The 2200MP won't display to a greater resolution than 800 x 600 - when I connect it to my laptop via the standard cable with blue connectors (VGA?), the resolution of my laptop is changed from 1920 x 1200 to 800 x 600 and I can then not see more than about 20% of the display - How can I get the 2200MP to dispay all of my screen information at the laptops resolution of 1920 x 1200? As soon as I disconnect the cable between the laptop and the 2200MP the laptop resolution instantly reverts to 1920 x 1200. Any advice on a way forward?

Using a VGA splitter to connect a laptop to a Devant TV can work, but it's important to note a few things:
1. **VGA Splitter Compatibility:** Ensure that the VGA splitter you're using supports the resolution and frequency of both your laptop and the Devant TV. Some cheaper splitters might not support higher resolutions, resulting in a lower quality display.
2. **Connection Setup:** Connect the VGA output from your laptop to the input of the VGA splitter. Then connect the two outputs of the splitter to the VGA inputs on the Devant TV.
3. **Settings on Laptop:** On your Mac, go to System Preferences > Displays. Ensure that the display settings are configured to extend or mirror the display to the external monitor (TV). You might need to detect displays or choose the appropriate resolution settings here.
4. **TV Input Source:** On your Devant TV, select the correct input source where you've connected the VGA cable.
5. **Signal Quality:** Be aware that using a VGA splitter might degrade the signal slightly, potentially impacting the quality of the display on both screens.
Remember that VGA is an analog signal and may not deliver the highest quality resolution compared to more modern digital standards like HDMI. If both your laptop and TV have HDMI ports, using an HDMI cable might result in a better quality connection.

If your netbook has an external VGA port (blue 9-pin connector) you may use the integrated dual display/extended/or external features of your netbook using the necVT460 VGA port. The resolution max supported is 800x600, so make sure you setup ur display at this resolution before attempting to extend the video signal.

Most newer TVs have a VGA connector on the back with the rest of the connectors. This is generally the easiest connector to use. You can get a VGA cable from a local computer store to connect between your computer video connection and the TV. If you have an old VGA monitor you are no longer using, you may find that the old VGA cable is removable - as they are on some monitors.

Alternatively, you can connect to an HDMI connector on your laptop / PC to the TV's HDMI connector (they should be labeled) using a standard HDMI cable if you have such a connection available. This is the preferred method if you have this connector available on both devices.

Third alternative option is if your computer (or TV) have a DVI connector. This connector can be adapted to HDMI. As an example, if your computer uses a DVI connector, and your TV has an HDMI connector on the back you could buy a DVI -> HDMI cable, or just use a HDMI cable with a HDMI -> DVI adapter on one end.

Once you have connected to the TV in one of the above methods, you then have to use the TV remote and change the 'input source' until you see your computer.

Side note: If you are using a laptop, make sure that your external connector is enabled - for Windows users, right click on the desktop and choose properties then Display. (Windows 8 users, choose screen resolution in the same location).

Good luck!

If the display works fine when connected to external screen via VGA connector then then the problem is either with the LCD display panel ( which consists of the display panel and inverter ) or the LCD cable that connects the LCD to the motherboard. You could try to re-seat the cable connection on the back of the LCD panel.

'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 :)

You didn't say, is the TV HDTV??
From Windows help menu, press F1, type in "VGA connection" I found this:

Why can't I hear audio when I connect my computer to an HDTV?

VGA, DVI, and component video cables do not support audio signals. HDMI cables do support audio signals, but not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer's sound card directly to the TV. Otherwise, you'll need to connect the audio signal to a different output device, such as external computer speakers or your home stereo system. For more information about sound cards, see Sound cards: frequently asked questions.


From Wikipedia.org search VGA connection:
1.
Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987,[1] but through its widespread adoption has also come to mean either an analog computer display standard, the 15-pin D-subminiature VGA connector or the 640×480 resolution itself. While this resolution was superseded in the personal computer market in the 1990s, it is becoming a popular resolution on mobile devices.[2]
VGA was the last graphical standard introduced by IBM that the majority of PC clone manufacturers conformed to, making it today (as of 2010[update]) the lowest common denominator that all PC graphics hardware can be expected to implement without device-specific driver software.[citation needed] For example, the Microsoft Windows splash screen appears while the machine is still operating in VGA mode, which is the reason that this screen always appears in reduced resolution and color depth.
VGA was officially superseded by IBM's Extended Graphics Array (XGA) standard, but in reality it was superseded by numerous slightly different extensions to VGA made by clone manufacturers that came to be known collectively as Super VGA.

2.
The same VGA cable can be used with a variety of supported VGA resolutions, ranging from 640x400px @70 Hz (24 MHz of signal bandwidth) to 1280x1024px @85 Hz (160 MHz) and up to 2048x1536px @85 Hz (388 MHz). There are no standards defining the quality required for each resolution, but higher-quality cables typically contain coaxial wiring and insulation which make them thicker. A quality cable should not suffer from signal crosstalk which occurs when the signals in one wire induce unwanted currents in adjacent wires, ghosting which occurs when impedance mismatches cause signals to be reflected (note that ghosting with long cables may not be the fault of the cable but may instead be caused by equipment with incorrect termination or by use of passive splitters), and other signal degradation effects; shorter VGA cables are less likely to introduce significant degradation. Some higher-end monitors and video cards featured 5 separate BNC connectors for RGBHV signal, allowing highest quality connection using five 75 Ohm coaxial cables.

I hope this helps, I find the sales reps at Best Buy very helpful.

Everything seems perfectly normal...

When you connect the computer to the monitor via an analog VGA cable, you get signal on the analog input.
When you connect them via a DVI cable, you feed the monitor's DIGITAL input, so the monitor doesn't get any signal on it's analog input, and informs you about it.
You have to select the digital input from the monitor's On Screen Menu, and then start the computer up - you should see the picture OK.
Also remember to set the display resolution on your computer to match the optimum (native) resolution of your monitor - this will give you optimum picture quality. In case of VA712B it will be 1280x1024.
Good luck and please come back with a testimonial if helped.

Unplug the television. Connect the VGA compatible monitor cable from the laptop's VGA monitor Output to the VGA Input on the back panel of the television. You will need a splitter to connect the audio cable from your laptop to the VGA Audio Input on the television. Never mind if you have speakers connected to your computer.

Press the Device button on the remote control or on the television front panel to display the Device Selection Menu. Select the device you want to view, in this case VGA. The only compatible resolution is 640X480 at a sync rate of 60 Hz.

Do not leave stationary or letter-box images on-screen for extended period of time to avoid uneven picture tube aging.

'Unsupported Signal' Error indicates that TV is accepting the signals for Video but not able to display because resolution doesn't matches. Else the message would be 'No Signal'.
Follow the steps-
NOTE- Make sure cable is 15 pin(at both ends) VGA cable, working fine between PC & Monitor.
1.The standard resolution of laptop(any) which would support is 1024*768.
2. Toggle the display output from Laptop Fn Keys depending on Laptop Brand.
3. Connect the cable after settings made.
Also PC Settings will not be highlighted until connection is made.

Yes VGA carries RGBHV--RGB and Horizontal and Vertical Sync information along with DDC info where available.

Now is that port on your TV a d-sub 15 pin standard VGA connector?
http://en.wikipedia.org/wiki/VGA_connector

If it is, then yeah you should be able to output VGA from a PC to the TV with a proper cable.

However if the TV has DVI or HDMI connections on it, it's better for you to connect it that way. DVI/HDMI is a digital signal and if it's a digital-based display tech TV, then you're better off using that. Also if the TV does resolution above 1360x768 (i.e. if it does 1080p) you can get higher resolution by going via DVI/HDMI...
