Question about Zenith Z20LA7R 20 in. EDTV-Ready LCD Television
Hi, I am trying to hook up my Zenith Tv model No. Z20LA7R to my computer. The only problem is, the place that i plug my vga cable in is called "for service" and I cannot find that station on my computer, nor does it recognize that i have a telivision hooked up. What do I do? Thanks
Watch my video and I explain the problem you're having with the VGA/PC input.

Ran into the same problem with this DVD player and my LG tv. Try this:
Open the DVD tray, with the DVD tray open press the HDMI select button until the proper resolution for your tv is illuminated, put the DVD back in, close the tray and try again. Simple fix -- worked beautifully for me.

To display a computer on a flat panel you need to match up the resolutions. go into the computer set up and make the display 720p or 1080p depending on what your tv is (the computer will read 1080x1900 and probably not say progressive unless you are using a aftermarket program instead of window). I do however recomend NOT using a plasma as a computer monitor as they WILL burn in. Even on brand new models the only brand I have found that has truely made it hard to burn in the TV is panasonic.

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!

Set the TV input to PC (that's ViewSonic's term for the VGA port).
Setting the computer to output to the PC may depend on your OS (XP, Vista). Reboot the computer after connecting the monitor and see if new hardware is found. Reboot again if you have a flickering screen. In Vista, right clicking on the desktop brings up various video and desktop options. Choose Screen Resolution and look for the multiple monitors line. Click Apply and OK after setting your desired output. In the Screen Resolution window you should see two monitor boxes (labeled 1 and 2) if the computer sees the monitor.
If the second monitor is not showing up (no new hardware found), check your BIOS and device drivers to see if you need to enable or update the drivers for the VGA port. Check your manual for the BIOS (often it is click F1 or F2 before the OS loads; it's often tricky timing and I have to try repeatedly). Device manager will have a red x if the port is disabled; the exclamation point (yellow triangle) indicates driver issues.
I realize this is nearly a year after you posted your questions but I hope it will help the next person searching for answers on this TV.
