Needs a Dark Room
A projector can’t actually reproduce black, so it projects nothing where black should be. That means, to have black up on screen, the room needs to be black—or at least dark. Since projectors rely on dark rooms to produce their best image quality, that might not be your best choice if there’s any amount of light in your space. Sure, ambient-light-rejecting screens like Screen Innovations’ Black Diamond or Stewart Filmscreen’s Phantom HALR do an admirable job of producing viewable images in lit rooms, but they can’t deliver the same picture quality as viewing in a darkened room.
Not Always Good for Gaming
Using a projector can be a con, depending on the types of games you like to play. Many projectors have an input delay of up to several seconds, which means there can be a noticeable lag between when you press a button and something happens on the screen. While this isn’t an issue when pausing a movie, it definitely can be when playing a videogame where milliseconds of reaction time can be the difference between onscreen life and death. Also, if you play games that require standing in front of the screen, you might find yourself blocking the projector’s light path and creating life-sized shadow puppets instead.
HDR and Brightness Inferior to TVs
HDR (high dynamic range) can deliver both deep, detailed blacks and ultra-bright colors, but projectors can only deliver a fraction of the necessary brightness levels. This makes HDR on a projection system tricky, with manufacturers searching for the best solution to tone map the high-brightness images for their projectors. Also, outside of a custom, dual Christie Dolby Cinema projection setup, you currently won’t find any projector that can support dynamic HDR metadata like DolbyVision. That isn’t to say projectors can’t pull off HDR, and some of the new laser-based models look pretty spectacular. But direct-view sets will likely always be superior in this regard, able to produce images with more punch and contrast.
Lack of 8K Support
I hate to even mention this, but 8K is now apparently a thing, so here we are. Yet no projector manufacturers seem to be seriously pursuing 8K resolution. This is especially surprising since if there was any technology that could benefit from 8K, it would be a massive front-projection screen. (But I digress . . .) I’ve only seen one projector that can deliver 8K resolution, and it was nearly the size of a small car, required its own ventilation system, and cost a wallet-blistering $400,000! (JVC will be launching a native 4K projector that uses the company’s eShift pixel-shifting technology to deliver a pseudo-8K image at a far more reasonable sub-$20,000.)
In my next post, I’ll break down the pros and cons of going with a traditional, direct-view TV set for your entertainment room’s display.
