Tried to plug in my mac to a dynex flatscreen using VGA gagaware chord. screen is black and says "not supported". is there a way to make this work?

Yes you can. Any cord that has the same prongs or just one that plugs in the same as the other cord will work.

you may have to select the vga input in the tv menu

Hi Nicole,

The MacMini should support any and all flat screens.
Please use the proper apple adaptor and you will be fine..

It is for sure that the fault is relative to the monitor as you have confirmed by testing and swapping. However this seems more related to a hardware issue and can be a fault in the input interface.
It will be necessary to have the board checked and signal /voltage analysed to confirm the case.

I have tried this on several occasions with different models of VGA to RCA converter boxes and the resulting screen images have always been extremely POOR.

If I were you, I would not bother spending any money on one of those converters. Just save the money and put it towards a decent computer monitor or a good flatscreen TV with a VGA input connection.

You can pick up a good old CRT computer monitor for next to nothing these days since everyone is just throwing them out and changing over to the flatscreen monitors. And if you want, you can even pick up a small brand new flatscreen monitor for about $100, so there's not much reason really to mess around with those questionable converter devices.

Good luck anyway.

Working with a cracked screen has overstressed the T-con board and the power source. Now they have failed for good.
Since the screen is defective this tv is effectively dead : try to sell it for parts (ask less than 75 pounds for it) and buy yourself a new one.

It could be a no. of things:

- Wrong input selected via the TV
- The VGA input on the TV is turned off
- Problem with the VGA cord
- Problem with either VGA port

there the basics, if there all great and it's still no working, try setting your Computer display to EXTEND rather then projector only, then play around with your graphic output settings.

UPDATE all your Drivers and check all your cables. PLUG IN YOUR LAPTOP, yes it will make a difference to the way the graphics card operates.

Hope this helps.

The IOGEAR GCS632U is designed to work with VGA computers and monitors. Using the Mini DVI to VGA adapter is not guaranteed to work with this KVM switch.

The Mini DVI to VGA adapter can only convert the port, but it does not have an ability to convert the signal from digital to analog when it's connected to the KVM switch.

What you need to have is a DVI to VGA SIGNAL converter. Unfortunately, I don't have a model number handy, so I would suggest to contact IOGEAR, because I'm sure that they already have a work around with this issue.

Thank you and good luck!

I went over the specs of the TV.
The max input for the VGA is 1360x768 at 60Hz. Anything higher will make the TV go bonkers.
I would try to get the resolution at 1360x768, then change the frequency to 60Hz.
