Optoma GT750 Projector – Image Quality 2

Optoma GT750 Black Levels & Shadow Detail

In the image above, of Mordor, from Lord of the Rings, you have plenty of detail, but the image is lacking in the contrast in the darkest areas, that a projector with better black performance would provide.

Below is an image we like for looking at black levels. It’s the starship image from The Fifth Element. All the images are a good bit overexposed. This allows you to get a better handle on the black levels. If the starship’s brightness is about the same, from image to image, then the projector with the blackest blacks in the letterbox and stars background, is the one with the blacker black performance. (A lot of bright stars in its own right may just reflect gamma differences. It’s the blacks you want to be watching).

As you compare the GT750 images to others, you can see that the starfield and the letterbox areas just aren’t as black as other projectors (when the starships are of similar brightness).

Shadow Detail Performance

Our comparison, once again turns to the night train scene from Bond’s Casino Royale.

Mentioned in many reviews previously, it seems that projectors with relatively poor black level performance tend to do extremely well at shadow detail. This is, if for no other reason, because the blacks and near blacks are so bright – due to the weak black level abilities. Thus, with everything “lightened” based on the the only slightly darker than medium gray blacks, shadow detail is everywhere.

And, as already noted, the black levels of the GT750 are extremely entry level.

For your curiosity, and for general demonstration of blacks and shadow details, here’s the GT750 taking on the usual other projectors, in the night train scene:

For whatever reasons, the GT750 did provide a bit better blacks than the GT720 did.

As I had mentioned elsewhere, if movies are your thing, and gaming is second, this image above is a good indicator of why the GT720 probably isn’t the best projector for you. On the other hand, if you are playing World of Warcraft, and find the dark areas too dark on many projectors, they’re probably just dandy, if a little lacking in dynamics, with the GT720 game projector.

Black Level and Shadow Detail Performance: GT750 Projector – Bottom Line

The GT750 is typical of sub-$1000 projectors, in both areas. Its real weakness is the black levels, so this isn’t for the movie enthusiast. Dark shadow detail, by comparison is really very good, better than many more expensive projectors (that have far better blacks).

Both are very secondary in terms of what’s important in the overall performance of a gaming projector, or one for the family, in a family room, on a garage door (inside or out), or a spare bedroom.
