Connect LCD TV to Mac G4 to use as monitor

I have a Mac G4, which has a VGA monitor port as well as a DVI. I bought an Insignia 15" LCD HDTV that has a PC RGB monitor port and came with a cable. The cable will connect the Mac VGA port and the PC port on the TV but all I get is a VGA No Support signal on the TV. Are they incompatible? Am I missing some kind of software that I need? The G4 worked fine when connected to my old fashioned monitor.

SOURCE: RGB port

A VGA & RGB port is the same thing. RGB is Red/ Green/ Blue for seperate input & VGA the video graphics array which does the same thing.
A DVi is an entirely different type of input port for digital input where your VGA port is more for analogue type inputs

SOURCE: 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!

How do I connect a PC to a LG50PG20 50" HDTV Plama?


You need a VGA cable (15 pin) connected from PC (monitor out) to the PC input on the HDTV (15 pin) this is for the video. For the audio, connect from PC to HDTV, audio cable, either 3.5mm from earphone out on PC to HDTV 3.5mm audio input (next to PC VGA input) and also be sure to set PC screen resolution to compatible output for HDTV like 1024 X 768 or 600 x 800 etc.

We have a panasonic 32"inch lcd tv.we want to


hdmi Ports Qty 3 port(s) PC Interface VGA (HD-15) HDCP Compatible Yes

I read your tv has 3 hdmi ports and a PC input.

if your pc has hdmi out - the you use a hdmi cable from the pc to the tv on one of the hdmi inputs.

if your pc has a 15pin vga cable you can unplug from your PC monitor (or go buy a VGA cable if you want to keep one on the tv and one on your pc monitor - or if you are using a laptop).

when you unplug the computer from the monitor .. check the pins - should look to be about 15 pins in the connector. it that will plug into the tv- then you are using a vga cable. if it will not plug into the tv pc input .. don't force it. It could be a dvi connector . .take the cable off the PC and to radio shack and they can fix you up (you need a dvi to vga cable - not likely, but possible)

I always turn off a pc before disconnecting monitors - and plug into the other display before turning the pc back on.

Good luck.
Bill.

I am trying to use my 32 inch Insignia HDTV as the display for my 13 inch macbook. I got an adapter for the vga, connected everything and turned then on. The display only shows one of my desktop pictures...


--==<[ DVI to VGA vs. DVI to HDMI ]>==-- Caleb, what you really want to do to get your Macbook working with the Insignia HDTV is to >RETURN< and exchange the DVI to VGA adapter for a DVI to HDMI adapter. This is assuming your hdtv has HDMI inputs (which I'm pretty sure all the insignia ones do! I own a 1080p 32" Insignia HDTV and it has 4 HDMI's). The reason you should exchange them is that DVI and HDMI are essentially the same connector (and a better connection than VGA), the only difference between DVI and HDMI is that HDMI additionaly contains two audio channel wires. HDMI (which is a smaller version of DVI) is a digital signal and will give you perfect picture quality compared to the analog 'pc vga' type connector you were converting it to with the adapter you described (not to mention it will probably just work immediately since there is intelligent 'handshaking' that goes on with an HDMI connection, so it will tell your HDTV what resolution to use rather than it having to guess....)
I am guessing by now you solved the problem since it was in June that you posted and it's now November as I write this, but I figured you're probably not the only one who tried hooking it up that way. And most people don't seem to realize that DVI and HDMI are essentially the same type of connection, just smaller, with audio added. So someone will most likely benefit from this posting =)

Connecting my MAC to my LCD TV!


Do you have a DVI port on the LCD screen? Please tell me what connections you have on your macbook and your TV. There may be a converter.

Normally HDTVs can only be hooked up through S video or DVI Depending on your video card.

Flat Panel Insignia 19


Lets see the cableing..

So you have a mac with a mini-dvi slot, you have a mini-dvi to dvi adapter, and then Dvi to vga adapter which connects to the tv?

The mini-dvi to dvi adapter doesn't have the analog VGA signal your tv needs. If I understood right.

Apple's mini-DVI to DVI-D cable does not carry the analog signal coming from the mini-DVI port on the Apple computer. This means that instead of buying a single mini-DVI cable from Apple and using a cheap DVI-to-VGA adaptor when you need VGA output, you must purchase another mini-DVI cable from Apple.

Insignia LCD TV won't recognize computer input...


Heres the dealyo.
Click start button
Click control panel
Click display
Click settings
adjust screen resolution (probably have to go down) until the tv displays your computer
if this did not work, you will have to adjust bit rate from 32 to 16. Fiddle with the settings until the magic happens.
You will not get any sound unless you use an audio jack plugged into t.v.

No signal


Weegee, Unfortunately you are trying to mix two different video types: VGA is an analog video interface found on most computers (except for latest with flat panel monitors, which are usually DVI). Your TV DVI interface is digital (although there is a DVI-A, which is an anlog DVI interface, it is unlikely that your TV has this). So, what you are trying to do probably won't work. I assume your computer does not have DVI output (otherwise you wouldn't have bought the adapter), but some monitors have VGA inputs; does yours? What kind of DVI adapter did you get? Is a DVI-A? Check out http://en.wikipedia.org/wiki/Dvi for info on DVI interfaces.
