Projectors: the ultimate in extreme PC displays

Projectors for gaming and movies are on the rise and it's easy to see why – bigger really is better.


PC owners just aren’t imaginative enough. Ask one to think of a big PC display and chances are their thoughts will dreamily drift towards a thirty incher from Dell. Compared to other PC displays thirty inches is a behemoth, but stand it next to a plasma or LCD TV and it starts looking like an oversized postage stamp. With increasingly large numbers of PCs being used exclusively for gaming and multimedia use, it’s time PC owners got serious about big screen displays. And when it comes to the best wall-fillers around, nothing beats a projector. 



Not only are projectors perfect for watching 3D Blu-ray movies in crystal clear 1080p, they’re absolutely amazing for PC gaming. You see, only the PC has the necessary grunt to deliver 1080p visuals at a rock steady 60fps. Try that on a PS3 or 360 and it’ll laugh in your over-expectant face. Once you’ve played the PC version of Battlefield 3 on a 2.5-metre wide screen, and have seen how beautifully crisp and clear it looks, there’s no going back. Projectors are becoming increasingly popular in Australia, but there’s still a lot of misinformation remaining from earlier projectors. Let’s try to clear some of that up.

Projector globes are nowhere near as expensive or short-lived as they used to be. Expect to pay around $300 for a globe that will last around 4,000 hours, so you’re only paying 7.5c per hour for this big-screen bliss. However, the biggest shortcoming of projectors is their need for a light-controlled room. Ambient light is a projector’s greatest enemy, but a set of thick curtains can work wonders. Most decent projectors still look great with a lamp or two nearby for a spot of TV viewing, but you’ll want a perfectly dark room when it’s time to fire up your movie or game.

There are two main types of projectors available – LCD (Liquid Crystal Display) and DLP (Digital Light Processing). We don’t have the space to explain how either works, so we'll only talk about the pros and cons of both. DLP projectors tend to have better contrast and blacker blacks, but they suffer from an issue called the rainbow effect. Moving objects in scenes have a subtle rainbow trail, and looking from one side of the scene to the other reveals the same thing. Some people are more susceptible to the Rainbow effect than others; for this author it’s an absolute deal breaker. LCD doesn’t suffer from this problem at all, and also has better colour reproduction, but at the cost of a more visible pixel structure and lower contrast. LCDs seem to be the dominant form of projector technology around the consumer/prosumer space these days, with DLP limited to the budget and upper ends of the market.

Having used a projector connected to a HTPC for several years, I agree it can be an excellent option. The room lighting issue is a big one for movies & games, although you can get away with watching sporting events with a fair amount of room lighting.

DLP sucks for me. Not only do I normally notice the annoying rainbow, but the alternating colours give me a headache when large areas are lit brightly for extended periods (like white backgrounds on Powerpoint style slideshows, or if I was browsing this site).

My projector is DLP, and no one has yet commented on the rainbow effect (I can induce it by waving my hand in front of my face).

With the improved contrast of LCDs these days I'll be getting an LCD for my next projector. The additional brightness that LCD projectors have would be nice for daytime viewing.

If I had the money I'd get a 3-chip DLP, which doesn't have the rainbow effect :)

If I had the money, I'd get a big-arse version of the new iPad's screen made up and bolt that to the wall... :P

Projectors rock! I've had a great experience with a cheap DLP projector. I'm well aware of it's limitations but it creates a proper floor to ceiling wall-o-vision that is great for movies but also allows you to run a desktop environment the way it was meant to be seen :-) If you can afford it, I'd say go straight for the HD LCD option - that's my next move.

I have a little portable DLP projector i setup in my "office" to watch movies to get away from the inlaws when they stay and it's footy season, and i hate it, (but it was free)

regardless of the cons on a LCD projector, i would never actually buy a DLP.

And the rainbow thing you can see if you look from side to side on the screen... well i can anyways.

OH, and i've noticed the duplicate post thing, seems to happen if you post THEN log into the site... :)

My post yesterday didn't make it up here Doh! ...

I had decided on LCD but I put in a crazy-low bid online for a DLP and actually won! It is a portable NEC with specs that are only now considered standard - 2200 lumens, xga (but looks better at 1440x1050) and auto everything. I spent more on the screen I built for it :-) For the last 3 years I've threatened to replay it at tax time, but I keep trotting it out ... we'll see this year - widescreen LCDs are coming down nicely.

oh, and before you start, it's acutally quite a pricey BenQ... i just can't be bothered pulling it out to check the model number...
