Anyone who's had to connect their notebook to a projector for the purposes of showing a presentation knows how frustrating it is to get the thing set up. Anyone who's sat in an audience (either at a conference or even just a regular boardroom meeting) knows how frustrating it is to watch as the speaker goes, "Now what buttons do I push to get the display to show up here and there?"
The fact is, connecting to a projector via the VGA cable and then figuring out the correct function and/or control keys to push is annoying. Thank God, then for DisplayLink, which recently teamed up with InFocus to launch two new projectors that connect to PCs via a USB cable. The same company that allowed users to connect computer monitors via USB (watch our video) has now taken that same technology and applied it to the world of projectors.
The new IN3100 ($1,499) and IN1100 ($1,299) models from InFocus include the DisplayLink technology, freeing presenters and audience members from the hassles of setup. Chips on the projectors include the drivers that install on the users' notebooks once the USB cable is connected. With the USB connection established, users can also control other features on the projector through the notebook instead of pushing other buttons on the projector.
The IN3100 (available in July) is designed as an in-room projector, featuring 3,000 or 3,500 lumens, a choice of XGA or WXGA resolution, and 2,000:1 contrast. The projector includes HDMI support and wireless connectivity (LiteShow II) support as well. The IN1100 (available in August) is a mobile projector (2.75 pounds), designed for mobile workers and smaller teams. Features include up to 2,200 lumens of brightness, XGA and WXGA native resolution, and 4:3 or 16:10 widescreen options.

Installing a device driver? On a business trip? Are you mad?
So you put the driver on your laptop, and when something goes wrong, instead of just the projector not working and having to copy your slides over to a borrowed laptop, you mess up your whole machine? And you're giving a presentation, so it's likely to be your work laptop, on a trip? Yikes.
I'd rather figure out my laptop's "VGA Out" setup once than play Russian Roulette with a driver every time I try a new projector.
Still seems easier than fumbling with VGA...
While I haven't tried this yet, I'd imagine that the driver install from the projector is not going to be that complicated for most people (it will probably be just like installing a USB mouse or keyboard). Having used the DisplayLink stuff before with their USB monitors, the driver install for that was pretty simple. I think the rewards of not having to mess around with VGA hookups and CTRL settings will make this much more appealing. Sure, some notebooks may have some driver issues, but the vast majority won't be affected, if done correctly.
How to Hook up Cable to a Projector
Instructions
Things You’ll Need:
Cable box with video output
Projector with video input
RCA composite cable
Coaxial cable
Hook Up Cable to a Projector
Step 1:
Check the characteristics of your projector before you attempt any connections. To be able to watch digital cable programs through your projector, you should have hdmi (High-Definition Multimedia Interface) capabilities. If you don't, you will need to invest in a special adapter cable to convert the signals so that both the projector and the cable box run on the same system.
Step 2:
Hook up the cable box to the projector using an RCA cable. Simply plug the cable into the video ports in both ends. Video ports are usually identified with the letter V or the color yellow.
Step 3:
Use a separate sound system for optimal audio. Rather than listening to the sound coming from your TV system, hook up the speakers to the audio input of the projector, and then run the cable through your DVD surround-sound or audio system.
Step 4:
Plug in both the projector and the cable box to an electrical outlet, making sure you use a coaxial cable to run from the projector to the outlet. You may need an adapter and a multiple plug, especially if you are adding outside audio.
Step 5:
Turn the projector on first, and then turn on the TV and cable TV box. The feeding should be automatic and should come through without any additional setup. If it doesn't, you may have a bad connection, so you will have to reset the cables. Other problems, such as doubled images or moving lines on the screen, are also probably the result of bad connections and are usually easy to remedy.
Tips & Warnings
When using a projector to watch cable TV, you will lose some of the available extras like closed captioning. There is no way to get around this, as a projector is only capable of reproducing the signal it receives (in this case, video) and cannot add anything to it.
