Many small businesses rely on presentations to gain new clients. Today, effective presentations include visual aids, often displayed digitally with a projector. Therefore, it is important to avoid potential incompatibilities between the projector or display monitor.

Most computers, monitors, and projectors use one of two main display standards - Video Graphics Array (VGA) or Digital Visual Interface (DVI). While these standards produce comparable quality at small and medium display resolutions, their physical connectors differ markedly. A VGA to DVI converter accepts VGA input and outputs at the DVI standard. Using one of these converters can ensure the a computer will be able to connect to common display devices.

Can you use a HDMI to dvi adapter and dvi to vga adapter to connect your ps3 from HDMI to your projector by vga?

No. HDMI to DVI uses a DVI-D or DVI-I connection and is digital, but a DVI to VGA uses a DVI-I or DVI-A and is analog. The best way to connect a PS3 to a projector is to see if the projector support component video through the VGA input using a VGA to component pigtail adapter. The projector might have even come with one. You then need to purchase a PS3 component video cable. This will allow resolutions up to 1080i (if your projector support it).

Is it possible to have a HDMI PORT installed in a laptop which doesnt have a HDMI port?

It would be MUCH cheaper to get an HDMI adapter for one of your other ports. For example you might have a DVI or mini-DVI port. Keep in mind though that DVI is video only. If you only have a VGA output, you can get a converter box that can covert VGA output to HDMI, but your laptop likely will not support HD resolutions.
