As our #5 choice for the best outdoor projector, the Optoma CinemaX P1 projector is an excellent choice for your 4K smart home viewing needs (the BenQ TK850 Projector is a cheaper 4K alternative). The Optoma P1 brings a lot to the table, outperforming many other UST projectors both in terms of visual & audio performance, thanks to a combination of laser projection & its excellent integrated sound system.\r\n\r\nWhy We Like It - Optoma CinemaX P1\r\nIn this Optoma CinemaX P1 Review, we\u2019ll go over what makes this ultra short throw projector worth the large investment it demands. The perfect addition to any home theater, the Optoma CinemaX P1 features two Dolby Digital full range speakers, a 1,500,000:1 contrast ratio, & an excellent 4K picture quality capable of producing 8.3 million pixels that work great when viewing HDR content.\r\n\r\nPerformance & Resolution\r\nThe CinemaX P1 is one of the many ultra short throw projectors currently available, but what separates it from the competition is its overall performance. The laser light design provides a 4K Ultra HD projection with an 8.3 million pixel display and a contrast ratio of 1,500,000:1. The projector has HDR 10 technology and a NuForce (Dolby Digital) 40W soundbar built-in for superior sound. Sadly, the projector has a bit too much input lag for competitive gaming (if you want low input lag for gaming, consider the BenQ HT2050A 1080p DLP projector instead).Looking for the perfect projector that will not give you a reason to complain? The Epson Home Cinema 2040 boasts exceptional picture quality, good adjustability, and connection options.\r\nBrightness & Lumens\r\nYou shouldn\u2019t have any trouble viewing this projector even in less-than-ideal lighting, thanks to the 3,000-lumen laser display. Optoma claims that the laser light system will offer up to 30,000 hours of maintenance-free use, so you won\u2019t need to worry about repairing or replacing the system anytime soon (which is good considering the price tag!). Still (as is the case with any projector) the image will considerably deteriorate as the overall ambient light increases, so for the clearest picture use this projector in a darker room if possible.\r\nAdjustability & Viewing Angle\r\nThis short throw projector is the perfect media player when you want a large display but only have a limited amount of space. The projected image will shrink as you put the projector closer to the wall, but if you place the device 14.5 inches away from the screen (or wall) you can expect it to produce a crystal clear 120\u201d display. You won\u2019t have any trouble viewing the projection from any angle on your screen of choice, making it perfect for showing videos to an audience.\r\nDurability\r\nWeighing in at 24 pounds, this portable projector is well-built and durable enough to withstand normal use. It doesn't have any impact or water resistance though, so you will want to make sure you place the UST projector in a stable place that can support its weight. Optoma claims the laser used to project images will last 30,000 hours without needing any maintenance, so short of blowing out the internal 40W speakers, this projector shouldn't require any specific care or maintenance.\r\nValue\r\nThe high price of this product is where many people will decide to choose something else. Costing $3,799.99, this is definitely an investment you will need to think about before purchasing (a MUCH cheaper alternative is the TMY V08 720P Native Projector). For that price, you will get the 24-lb. projector, a remote, a warranty (5 years or 12,00 hours on the light source & a 2-year parts\/labor warranty on the projector itself), and free shipping. Thankfully, if you decide this product isn\u2019t for you, returns are free as well!\r\nOptoma CinemaX P1 Wrap Up\r\nThis Optoma CinemaX P1 Review covered everything you need to know about this laser-light projector. The price will definitely be a deterrent for most, but if you can afford it, we definitely think it\u2019s worth it (if not for the 4K HDR quality than for the excellent built-in speakers!). If you decide it\u2019s not worth the investment for you, Optoma also has many other lower-priced projectors you could consider as well!
