The BenQ has a distinct advantage when it comes to color but both projectors do cover an extremely wide color gamut.

BenQ HT4550i!

Why Buy The BenQ HT4550i?

This contest really could have gone either way. So why did we choose the BenQ HT4550i over the Optoma UHZ50?

The BenQ HT4550i wins this showdown because of the picture quality. While the UHZ50 produces a fantastic image the picture you get from the HT4550i is better. It's sharper thanks to the larger DLP Chip and more vibrant thanks to the 4LED light source. Both are excellent gaming projectors, but when it comes to movie watching the HT4550i comes out ahead.

The brighter light output is also a bonus, especially for those looking to enjoy their entertainment device with the lights on.

Another big advantage of the BenQ HT4550i is the lens shift. While not to the degree of a projector like the Epson LS11000, the lens shift offered by the BenQ projector gives you more installation versatility. The Optoma UHZ50 needs to be lined up perfectly with the projector screen, making installation more of a challenge.

BenQ has shown us with the HT4550i that LED projectors have come a long way and are now on par with the likes of laser projectors.

Why Buy The Optoma UHZ50?

If we were purely basing our winner on gaming performance the Optoma UHZ50 would be the champion. Its somewhat lower lag time helps give you an edge in FPS and other high speed games.

We typically recommend external speakers over those integrated into the projector. However if you're planning to use the built-in speakers on your projector, you're going to be happier using the Optoma UHZ50 with its more powerful and robust audio.

The three HDMI ports also give it a bonus for anyone who wants to connect multiple consoles.

For those looking to save money, the Optoma UHZ50 would be the better choice for them. The picture quality you get from this 4K Optoma projector is really and you'll still be happy, especially your wallet.
