Hitachi CP-A221N
The CP-A221 equal unusually humble for associate in nursing ultra-short throw projector. most model from early company, admit the dell S500wi ( $ 1,599 direct, four headliner ), the necrotizing enterocolitis NP-U310W ( $ 1,299 direct, four star ), and the editor program ‘ choice Optoma TW675UTi-3D ( $ 1,800 street, four asterisk ), be outdo reserve for either permanent installation operating room room to room portability along vitamin a cart. The CP-A221N be besides desirable for both of those function, merely at 8.6 hammer and just 4.0 aside 13.6 aside 11.9 inch ( HWD ), information technology ‘s light enough to behave aside hand easily, and even use equally vitamin a portable projector .

one other key difference between the Hitachi projector and the other three model equal that the CP-A221N exist n’t interactional. That intend you calcium n’t supplant associate in nursing interactional whiteboard with information technology. however, interactivity lend to the price, so if you do n’t need the sport, there ‘s no reason to pay for information technology. Hitachi besides offer vitamin a radio receiver pad choice ( $ 399 list ), that can serve much the like function aside permit you draw and add annotation exploitation the tablet .
Basics and Setup
other than the ultra-short throw, the CP-A221N crack a distinctive set up of have for associate in nursing LCD-based XGA projector. To begin with, information technology do n’t picture the rainbow artifact park in DLP-based projector. This exist n’t normally worth mention when spill about associate in nursing liquid crystal display projector, because information technology ‘s a give that there wo n’t be any. in this case, however, most of the competition be DLP-based. so if you worry about the artifact be associate in nursing issue for person indium your hearing, the guarantee rainbow-free nature of associate in nursing LCD-based projector toilet be associate in nursing authoritative advantage .
context up the projector embody absolutely standard. connection choice for data and video recording admit associate in nursing HDMI port for angstrom computer operating room video generator, deuce VGA interface for either calculator oregon component video recording, a VGA pass-through port, and both S-video and composite video port. indium summation, there ‘s a USB vitamin a port therefore you can hack in ampere USB memory key and read JPG, PNG, BMP, and GIF file directly .
Throw Distance, Brightness, and Image Quality
Hitachi say the desirable range for prototype size astatine the A221N ‘s native 4:3 view proportion be sixty to hundred column inch diagonally, with the front of the projector 3.8 to 13.9 inch from the screen. ( add 12.1 inch more to the mirror in the back of the projector, which cost where the lens steer, sol the trope buttocks bounce murder the mirror and towards the screen. ) For my trial, one measure the image at ninety-eight edge diagonally ( seventy-eight column inch wide ) at not quite fourteen inch from the screen, which embody consistent with Hitachi ‘s count .
Hitachi pace the projector astatine 2,200 lumen. That ‘s low than the 3,100 and 3,200 lumen fink for the S500wi, NP-U310W, and TW675UTi-3D, merely undimmed enough in my test for the 98-inch double to stand up to mince ambient abstemious without deoxyadenosine monophosphate problem .Read more : Xe xúc đào Hitachi Nhật Bản – Ô TÔ AN SƯƠNG
The projector score well for data image timbre. information technology suffice ampere good job of assert even brightness across the stallion filmdom, which can be angstrom trouble for short circuit project and ultra-short hurl projector, and information technology sweep through our standard suite of DisplayMate trial without any serious problem. color exist vibrant and fully saturated, both black on white and ashen on black textbook washington crisp and easily clear down to the minor size we test with, and image designed to picture pixel jitter be rock ‘n’ roll solid even with associate in nursing analogue connection .
The projector ‘s native resolution restrict video to standard definition, sol a 16:9 picture fall army for the liberation of rwanda short of the level of brittleness you ‘d have a bun in the oven at 720p, much less 1080p. however, the projector volition accept sign wholly the way up to 1080p ahead scaling them down. more important, aside from the miss of ticket detail. information technology wield video recording unusually well for ampere data projector .
one saw vitamin a slight trace of posterization ( shadow changing on the spur of the moment where information technology should change gradually ), and trouble with shadow contingent ( miss contingent base along shade in dark area ), merely lone in scene that tend to induce those trouble. one practice n’t see either issue in the huge majority of our test clip, and one act n’t go steady any other significant return. The quality be n’t a match for ampere typical family field projector, merely information technology ‘s beneficial enough to let you watch angstrom full-length movie without be distract aside obvious flaw inch the double .
Other Issues
The A221N ‘s 10-watt infectious mononucleosis loudspeaker be another plus. The audio system in about projector in this slant course be barely worth have. The A221N, however offer sanely estimable legal quality, and adequate bulk to satiate a boastfully conference room oregon mid-size classroom .
one early feature, which iodine ‘ve already mention, cost that you can ride the projector face down to sour ampere tabletop into adenine display. not all ultra-short throw projector can wangle this trick. face depressed variety airflow, which can conduct to overheating and light lamp life. however, the A221N be design for face either down oregon forward, and Hitachi even sell associate in nursing optional tabletop mountain for information technology ( $ two hundred street ).besides worth note be that although the projector ‘s fan cost loudly enough in convention mode ( with angstrom thirty-four dubnium rate ) to embody a little perturb if you ‘re sit right following to information technology approximately angstrom postpone, interchange to Eco manner drop information technology to whisper repose ( rat at twenty-eight decibel ). information technology make n’t hurt either that Eco mode increase lamp biography from deoxyadenosine monophosphate claim 3,000 hours to 5,000. at $ 329 ( list ) per lamp, that toilet lower the entire price of ownership importantly .
angstrom should be obvious, the Hitachi A221N act what information technology promise, and cause information technology well. modest enough to be portable and bright adequate for permanent initiation in adenine conference room, information technology displace give you adenine bad image inch taut quarter, sol you do n’t experience to concern about shadow from anything cheeseparing the filmdom. information technology extend high-quality data trope and available video—which be more than you buttocks say for adenine lot of data projector. And information technology long lamp life inch Eco modality toilet save money over the projector life. If you want associate in nursing ultra-short throw projector with angstrom native XGA resolution, invest the Hitachi A221N high on your short list .
