Did you tell the TV to "listen" to the VGA port, instead of the "cable" or "DVD" or "VCR" ports?

How do I convert a Westinghouse 22" LCM-22w3 DVI/VGA LCD Monitor into an HDTV?


Dear Amy,

Normally, monitors do not have tuning electronics for capturing TV signals.
Therefore, consider the monitor as a "dumb" unit that only displays information coming from your computer. Also, this unit does not have a HDMI input, but only VGA.
So, you are fated to have this monitor connected to your computer, always.
Now, you may find good software that will "tune" the TV signals from streaming at the Internet and show whatever is being broadcast. The same way you can access YouTube and watch videos these TV tuners will get the streaming signals the TV stations send via Internet (not all do that) and watch the channel in your PC/monitor
Since I do not have additional information about the computer you use I cannot give you other ideas
I hope I have helped you.

Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

Can i turn my vizio m190va tv into a computer monitor?


Unfortunately. the HDMI port on the M190VA does not interpret the signal from a computer. The HDMI signal from a set-top box is different than that of a computer. You need to use the VGA port and the PC audio in on the TV; if your computer doesn't have a VGA port, use a DVI to VGA adapter or other appropriate adapter. You will need a 3.5 mm audio patch cable to use the TV's speakers. See page 25 of the M190VA manual here: http://store.vizio.com/documents/downloads/hdtv/M190VA/364User%20Manual.pdf .

I wish that I had better news for you.

I have a Jensen (JE1909ACB) 19 LCD TV Can't get it to hook up as a monitor on my desktop. It reply's unsupported mode.


Are you using the VGA port on the Jensen TV? What is your computer's OS?

The usual reason for the unsupported mode message is that the the computer did not recognize the TV as a monitor on boot up or that the previous settings were incompatible with the TV. (For example, if you previously had a CRT connected to the computer and used a refresh rate of 75 Hz, the TV can't handle the refresh rate. It needs to be set at 60 Hz.)

First turn off both the TV and the computer. Then turn on the TV and set it for the PC input (assuming you are using the VGA port). Next turn on the computer. If you have Windows XP or later, it should find the TV and set the resolution without any input. (If it doesn't, use a different monitor and set the resolution to 1366 x 768 and 60 Hz. Then try again.) If you used the HDMI port, try the VGA port. This TV doesn't understand a computer signal over the HDMI port (only set top boxes).

I hope this helps.

Can i hook my 47inch tv to the monitor


You can't hook you TV to the monitor itself, rather the computer.
If your PC has a wide white connector (DVI) that is supplying signal to the monitor, you could use a DVI to HDMI adapter cable to connect your PC to your TV. This is also possible if your PC uses a small blue connector with 15 pin holes (VGA) by using a VGA cable to connect your PC to your TV.

How do I hook up my hp computer to my lg flat screen tv


You can use the TV's VGA port which needs a VGA cable which you can get from a computer hardware store. It's called RGB in on your TV. This is also called PC input.The max resolution you will get is 1,366x768 off your PC.

Trouble connecting Insignia HDTV 19" to my macbook pro


One of the first things you may notice about your new big-screen HDTV is that it has more connections for video than your old TV ever dreamed about. It probably has two or three HDMI connections, maybe a DVI connector, a VGA connector, and at least one component video connection. And those are just the connections most commonly used for high definition.
It’s shame to let all those connections go to waste. Your Mac just happens to be sitting nearby; why not hook it up to your new HDTV? It's actually a pretty easy task. A few lucky souls won't even need an adapter; for the rest of us, at least one adapter will be necessary.
Pick the Right HDTV PortFor best quality, your HDTV's HDMI or DVI ports are the preferred connection method. Both are capable of the same digital quality. The only practical differences are the style of the connector and the fact that HDMI supports video and audio in a single connection.If it has one, another option is to use your HDTV’s VGA port. The VGA connection isn't as good as the HDMI or DVI method, but as long as your TV supports full resolution via the VGA port, you'll be hard pressed to notice the difference.Mac Pro, MacBook Pro, Mac MiniMac Pros, MacBook Pros, and Mac Minis have standard DVI connectors. Mac Minis and MacBook Pros have a single DVI port; Mac Pros have at least two DVI ports.If your HDTV has a free DVI port, then all you need is a standard DVD cable; no adapter is necessary. But in all likelihood, you'll need to connect your Mac to your HDTV using either an HDMI or VGA connection; both options require an adapter. If you choose VGA, you can use the adapter that came with your Mac.If you choose HDMI, you'll need a simple adapter, which is available from multiple sources. The adapter may be a cable with a DVI connector on one end and an HDMI connector on the other, or it may be a small adapter that has both types of connectors, but no cable. Either type will work fine.iMac, MacBookiMacs and MacBooks have a mini DVI connector for hooking up external monitors or TVs. You'll need at least one adapter, maybe even two. At a minimum, you'll need a mini DVI-to-DVI adapter. You may also need a DVI-to-HDMI or DVI-to-VGA adapter, depending on which port on the HDTV you choose for the connection.Make the ConnectionOnce you determine which, if any, adapters you need, and have the necessary cable to reach from your Mac to the HDTV, turn off both the HDTV and the Mac. Connect the cable between the Mac and the HDTV.Turn the HDTV back on first. It doesn't need to be set to the connection the Mac is on, but it must be powered up first, so that when it boots, your Mac can recognize the TV and the resolution it needs. Once the HDTV is powered up, turn on the Mac.Your Mac should recognize the format and resolution of the TV, and automatically select the native resolution of the TV for running the video. In a few seconds, you should see the Mac desktop on the HDTV.Over or UnderscanYou may notice that the Mac's desktop appears to be slightly larger than the HDTV's screen (its edges are cut off); this is called overscan. Or, you may notice that the desktop doesn't occupy all of the HDTV's screen real estate (there are dark areas around the edges); this is called underscan.You can usually correct either issue by making adjustments on the HDTV. Check the HDTV's manual for information on making scan-related adjustments. They may be called overscan, underscan, dot-by-dot, or pixel-by-pixel. If your HDTV has a dot-by-dot or pixel-by-pixel capability, give this a try; it should eliminate any over or underscan issues. Some HDTVs only offer these special scan controls on specific inputs, so be sure to connect to the corresponding input on your HDTV.Time to Watch a MovieOnce you have your Mac and HDTV working together, it's time to kick back and watch a video from your Mac. Be sure to check out the QuickTime HD trailers for a sense of what HD and your Mac is capable of. Enjoy!

I would check the video setting on your laptop. The resolution or refresh rate might have been changed and the LCD TV might not be able to process the signal. Try changing the laptop's resolution to the lowest setting(right-click on desktop and pick properties) and see if the TV produces a picture. Also verify the video output on the laptop is working by hooking it up to a computer monitor if available.
