OK, mini display port to VGA adapter-is the VGA cord the one that goes into the port labeled RGB and audio on the back of the Samsung? Sorry to be a dummy but Samsung monitor is 6 years old and has always...


An RGB port is for a component cable not a VGA cable. A VGA cable, similar to a component cable, only carries a video signal but is a 15 pin cable that nearly all monitors and HDTVs support. Most laptops have a VGA out port.
You should be able to connect your laptop to almost any monitor (not sure about your Samsung) with a male to male VGA cable.

Good luck and thanks for using FixYa.

You need to lower down the screen resolution. Check the setting of your mac mini then adjust the screen resolution to the lowest.

I am getting a "no signal" on the blue screen on DTV mode of my Protron PLTV-3750 LCD. It has worked until I moved it to a different room. The signal is good on other tv. Anything I can do?


First make sure you have your cables connected securely, then try to move your antenna around and rescan your channels everytime you move the antenna.

Same power trouble on Protron PLTV-3750


It seems like the voltage that is powering up the microprocessor is not working properly and the power supply will need to be service.

Using protron as a monitor with mac


Need to set resolution and refresh rate on the Mac before plugging in to the TV set - had this same problem with a WinVista machine. According to the documentation, the only supported resolutions are:

640x480 60Hz
800x600 56Hz
800x600 60Hz
1024x768 60Hz
1280x1024 60Hz
1280x768 60Hz
1366x768 60Hz

In all fairness, I cannot get the unit to run in 1366x768, though - get out of range. 1360x768 seems to work OK though. Only real problem with the VGA input is that regular text mode on a video card (more of an issue on Windows machines) does not work.
