Projectors have always offered larger screen sizes compared with “traditional” displays, but they come with drawbacks like poor resolution, expensive replacement bulbs, and restrictive requirements for placement. Those problems might go away forever with the newly unveiled Dell Advanced 4K Laser Projector. As the name suggests, this is a 4K projector that uses lasers instead of a regular lamp. It’s not cheap, but it can produce a 100-inch image. A 100-inch 4K TV wouldn’t be cheap either.
The Dell Advanced 4K Laser Projector (S718QL) is intended for use in an office or classroom setting, but Dell will happily take your money if you want to use the new projector in your living room. It’s more viable for general use than previous projectors for several reason, perhaps most importantly the “throw distance.” Most projectors require at least a few feet of distance to the screen, which makes a large portion of the room a no-walking zone unless your intention is to insert shadow puppets into your content. The new Dell projector is ultra-short throw, so it can project a 4K image at 100-inches just 4 inches away from the wall.
If you’ve ever gone looking for a projector bulb, you probably considered just throwing the projector out — the lamp for a high-end projector can run more than $100. Dell’s laser projector doesn’t even have a bulb, so there’s no worry there. It says the projector should operate normally for at least 10 years, and that assumed eight hours of continuous use five days per week. You might not even use it that long in a home environment, so it could last at least until 4K is boring.
Dell further claims that this projector has a high enough output that it can be used in daylight conditions. So, no heavy curtains required. The resolution is 4K, but it also supports HDR. Some would claim that makes a bigger difference than simply bumping the resolution. It can receive inputs over the network connection, so up to four devices can project content at the same time. There’s Bluetooth as well, but that’s just for streaming audio.
Dell expects to launch the Advanced 4K Laser Projector on July 19th, at which time you can drop a whopping $5,999 on it. Still, that isn’t an obscene amount considering the competition. Samsung’s 88-inch 4K TV is $15,000 and LG’s 86-inch unit is $8,000. There are people who would consider buying these for their home theaters, so there’s probably a market for the Dell Advanced Laser Projector, too.
