the InFocus ScreenPlay 4800 be a reincarnation of the very popular InFocus ' x1 DLP Projector . the 4800 have a remote but , otherwise , be identical to the x1 . recently InFocus have release a x2 model which have 1500 lumen -lrb- brighter bulb , up from 1000\/1100 lumen -rrb- . since Amazon like to know about best pricing you can obtain a x2 for about $ 1000 and the x1 be available for $ 900 at various vendor 's on the internet . I purchase my screenplay 4800 at Costco for $ 1200 and it include a 6 ' by 3.8 ' self contain -lrb- roll down or up from floor -rrb- screen which be at least a $ 200 value .  this projector -lrb- 4800 -rrb- be a outstanding value and perform with stunning clarity and overall excellence . the accompany documentation be thorough and setup be very easy .  I have use the projector for viewee dvd 's , watch standard cable broadcast sport and tv programming and for project my computer -lrb- notebook -rrb- display all with great ease and great satisfaction . dvd movie view use the projector 's component input produce crystal clear image that be smooth and virtually amazing .  the lamp life be rate at generous 4000 hour and a replacement lamp be price at $ 300 .  any flat white wall will do nicely if you do not have a view screen . even though I have a projection screen I purchase a 48 '' by 36 '' clear white -lrb- reflective -rrb- `` marker board '' -lrb- $ 9.00 -rrb- and mount it on the wall in my home studio and the result be as good as any $ 3000 + plasma screen tv .  the dlp technology rock ! Infocus be now -lrb- I believe -rrb- in they 13th generation of projector and they have it down pat . some people may -lrb- very few by percentage -rrb- notice a slight -lrb- and infrequent -rrb- `` rainbow effect '' that be inherent in all dlp technology projector . the `` rainbow effect '' be fleeting and infrequent sparkle in some small area of project video and not something that be continuous nor large -lrb- size of a dime -rrb- . the effect be minimal and fleeting -lrb- one frame -rrb- and be , in my opinion , as close as you can get to `` of no consequence '' . someone who can see these `` rainbow effect '' may notice two or three in a entire feature film . so , if you get a dlp technology projector you may not want to invite any Virgo 's to you screening party . : - -rrb-  ideally , to use any projector -lrb- regardless of luman rating -rrb- you need to have control of you ambient lighting . the best viewing be in a room where the lighting can imitate that of a movie theater . you can imagine how a project image would be in a regular movie theater with daylight streaming in through picture window . the same situation will exist in you home . the darker the room the better the visual quality . Night time view present no strategic lighting issue .  to get a project image -lrb- 16:9 -rrb- that be 7 foot -lrb- diagonal -rrb- across you will need about 14 foot distance from you projector to you wall or movie screen . eight foot distance will give you a five foot diagonal image . so space -lrb- `` The Final Frontier '' -rrb- be a consideration . the project image also allow for a view angle of about 120 degree unlike plasma screen tv 's .  bottom line : the InFocus ScreenPlay 4800 DLP projector be a expression of technological excellence . stellar movie , jaw drop video , ease of use , legendary bulb life , greatly enhance tv viewing , superior mobility , 2 year part and labor warranty -lrb- exclusive of bulb -rrb- at a bargain price compare to plasma screen tv , lcd tv and some rear projection tv 's .  with the 4800 I have a `` better than '' plasma screen tv , with a minimal footprint , with a 55 inch diagonal picture -lrb- 8 foot from projector to `` message board '' view screen -rrb- and it actually feel like you be on the bridge of the Starship Enterprise -lrb- Spike tv -rrb- and dvd 's be magnificent and televised sport give you the best seat in the arena . if you be look for a DLP Projector without have to get a advanced degree in Rocket Science then the 4800 fill the bill .
