plexer Posted February 13, 2013 Posted February 13, 2013 If you now the calculations for a given projector and screen please add to this thread and in the future the info can be transferred to the wiki etc... Hopefully this will help when people are looking for replacement projectors and can't afford a Casio Projector make: Epson Projector mode: EB-X12 IWB make: Promethean IWB model: ProActiv 78 Distance from front of lens to board minimum: 2.4m Distance from front of lens to board maximum: 2.9m 1
plexer Posted February 13, 2013 Author Posted February 13, 2013 I did look at the Epson one and found it awful tbh. The more useful info came from the user manual for the projector. Ben
Educare_AV Posted February 13, 2013 Posted February 13, 2013 This is also a great calculator as it takes ambient light etc into account. Projection Calculator Pro - Projector to Screen Distance 1
plexer Posted February 13, 2013 Author Posted February 13, 2013 The other thing I don't like with most manafacturers tools is you have to pick a projector first, I want to be able to input my scenario and have it suggest compatible units. Edugeek web project anyone? Ben
plexer Posted February 13, 2013 Author Posted February 13, 2013 Bit like this one: Find Projectors By Feature You can enter the throw and size at the bottom shame it's all american. Ben
john Posted February 14, 2013 Posted February 14, 2013 I just use this one every time: Projector Screen Size Calculator It has never let me down, you select the make and model and then metric / imperial and either tap in what you want or drag the projector to play around
richardg7vyi Posted September 30, 2013 Posted September 30, 2013 Hitachi Projectors have a calculator on their website: Throw Distance Calculator : Hitachi Digital Media Group
richardg7vyi Posted September 30, 2013 Posted September 30, 2013 Also some suppliers on line do too one example here: Projection distance calculator at Projectorshop24.co.uk
plexer Posted September 30, 2013 Author Posted September 30, 2013 Those links are all great but recommendations on projectors that have been fitted would be great as real world examples can be more accurate than just what the calculators say Ben
john Posted September 30, 2013 Posted September 30, 2013 Those links are all great but recommendations on projectors that have been fitted would be great as real world examples can be more accurate than just what the calculators say Ben I will say the Projector Point calculator I linked to has always been very accurate for my needs with Casio, Hitachi, In-Focus and NEC Projectors that I have fitted with it.
