In response to NPatel I would greatly appreciate any help! Also, if your projector has anything higher than p resolution — then you cannot support the extra pixels. Rather than wasting money on installing HDMI cables, adapters, and switches — consider going wire-less.

While there are dozens of different wireless products available today, only a handful of them has been adopted into commercial applications such as schools and corporate meeting rooms. For example, the inexpensive Google Chromecast is in millions of homes but has significant shortcomings when use in a classroom or collaboration space. A better solution for these spaces may be a wireless presentation system. While these systems are typically more expensive than a Chromecast stick, they are designed for classroom and meeting room use.

For example, the BenQ InstaShow solutions can be easily installed on top of a ceiling-mounted HDMI ready projector in minutes — and then a teacher or presenter connects in seconds using a button to present. These buttons can be used with any notebook, Chromebook, media player, or even digital camera, to wirelessly send p video and audio content to your projector. For medium-sized and larger collaboration spaces, the InstaShow S WDC20 has additional features such as the ability to wirelessly connect to a phone something impossible with VGA , and the ability to display four different presenter screens at the same time on a single display — at 4K resolution.

For about the same price a contractor would charge you to replace VGA cables with HDMI, you may be able to transition to wireless presentation system— and dramatically improve your learning or collaboration space capabilities.

It is the only popular video standard with analog and digital signal support in the same connector. In contrast, its competitors, such as LVDS, switched to digital right away. DVI format can support analog signals, digital signals, or a combination of digital and analog.

This compatibility led to the widespread usage of the DVI format. DVI-I combines digital and analog signals in the same connector. DVI-D carries digital signals only hence the letter D in its name. DVI-A carries only analog signals. You can use single link connectors with resolutions of up to x at 60Hz. Dual link connectors have more pins compared to single link connectors and can support up to x at 60Hz or 3, x 2, at 33 Hz Note: dual link connection has nothing to do with dual monitors, which is a separate subject.

VGA monitors are also very easy to connect to computers and other devices that have DVI video source interface. One of the reasons why HDMI became popular very quickly was that it was created by 7 companies. The goal was to create a digital interface that would be backwards compatible with DVI.
