which one will give me better clarity&hd?

i have a sony projector
which has both rgb and vga

The HDFury is a great way to get 1080i into your projector. It would connect to the 5 RGBHV terminals on the back. You can also put another input board in next to the one you have and add more options.

Do you mean VGA and component video? If so, VGA will be better. The HD Fury is a great way to input HDMI into the projector. What model is the projector?

VGA and RGB is practically the same. Just a different connector and sync setup.
It depends on if the RGB is RGsB or RGBS or RGBHV...this may determine what your projector can handle.
But in a VGA connector, there is a RGBHV signal.

There's a lot of confusing/misleading information here guys!

RGBHV is a type if signal. VGA is a type of connector. The two are not related. Yes, often an RGBHV signal is passed over a VGA (DB15) connector, but component (YPbPr) signals are also often sent through a VGA style (DB15) connector.

Well that's even more misinformation. VGA which stands for Video Graphics Array is a term coined by IBM and is actually a specific resolution, but it is used generically for analog computer video signals that typically use an RGBHV signal format. The connector is an HD15 that has 3 rows of 5 pins. DB15's were used by Apple and have 2 rows, one of 7 and the other 8.

^ Indeed.
VGA is actually a graphics standard that relates to the signal and not the connector. The connector is actually called a DB15.
This is what happens when you read too much commerical rubbish.

VGA = Signal Standard.
RGB(HV/S/s) = Signal.
DB15 = A connector that often relays VGA or RGB signals.

This is exactly why i said, that VGA and RGB is in fact prettey similar ;)
