My computer monitor wont start up

what problem did you encounter, if just only a cable not compatible you can use a dvi to vga adapter plug.

It all depends on what kind of PORT connection you have on your MAC either VGA or DVI. If your Mac has VGA port then you need to use the blue cable that comes with your Monitor when you bought if you have DVI then you need to connect the white cable.

How to know if you have VGA or DVI or BOTH.

1. Check the sides of you mac and see if you have a blue port. Blue port means you have VGA port
2. IF you have white then that means you have DVI
3. IF you have both then you just need to use 1 connection. I prefer DVI since its digital.


Your feedback is greatly appreciated. Thank you for using FIXYA.

The monitor appears to be DVI capable, (White connector with a grid pattern). You will need to connect the monitor to the computer using a DVI cable (White connector with grid pattern and plus sign shape on one side). If your computer is not capable of connecting to a DVI monitor check to see if the monitor has a Blue VGA (Blue Zig Zag Openings) and connect it with a VGA cable. If your monitor only has the white DVI connector and your computer only has a Blue VGA connector you will need to go to the store (Best Buy, Walmart, Etc) to buy a small adapter that will convert DVI to VGA. If you ask someone for a DVI to VGA adapter they will know what you are talking about. I hope this helps.

Hi,

I am not too sure if you have tried this but this might help, for what i know your monitor have 2 ports for video (DVI and VGA). VGA is the one with color blue adapter, while the DVI is white. If your using VGA for both computer might be you can try DVI or from DVI to VGA. Also try a different cable for both VGA and DVI. If still the same might as well contact the Acer and check the warranty, normally monitor had 2-3 years of warranty, Have it replace if still under warranty.

I hope this works on your issue.

thank you for choosing Fixya.

Try connecting the monitor to your computer via a VGA cable instead of DVI. (The blue instead of white cable)

The LG 32LD550 television has HDMI and VGA.
Your iMac has a mini-DVI output port with support for DVI, VGA, S-video, and composite video connections via adapter.
So all you need is either:
1) mini-DVI to VGA adapter.
2) mini-DVI to HDMI adapter.

HDMI is better quality, and so I'd recommend something like this: http://www.amazon.com/PTC-Mini-DVI-Adapter-6ft-Macintosh/dp/B001H0REVK (You may want a longer cable though).

It depends on what sort of monitor you mean, if it's an external monitor for your Mac it would need a mini dvi cable but if the monitor you want to add on is a vga or dvi monitor you will need a mini dvi to vga cable which can be found here : http://store.apple.com/uk/product/M9320G/A . Or a mini dvi to dvi cable found here : http://store.apple.com/uk/product/M9321G/B . If it is a Mac Pro which does not come with a built in screen and it's a primary monitor you want to connect it would probably have a cable with the monitor. Hope this helps.

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!

Your setup is probably in "extended" mode - if you move the mouse back in forth, when it leaves the Mac Pro screen you should see it on the external plasma monitor. You can switch to "mirror" mode if you want to see the same thing on both screens. Or put the computer into "sleep" mode, close the lid, connect an external keyboard and the plasma display and wake it up by pressing keys on the keyboard. Then you should see the desktop on the monitor.

what resolution are you setting your screen to? if you are setting it too high or to a resolution/frequency that your monitor doesn't support, it will do this. Try setting it to 800 x 600 w/ 32 bit color and a frequency of 60Hz. If you do this and the monitor still blinks, you may just have a bad DVI cable.
