Hello!


I finally got my projector working at high resolutions and now the task is to choose best one for DVD and HTPC.


I am thinking as follows:



My projector (Barco BG1200) advetized to have 120Mhz bandwith.


It handles well 2048x1536x72Hz

(how can that be? 120Mhz should not be enough for this resolution.)


But it does not handle 1900x1200x70Hz (screen is corrupted)


If standart screen size for DVD is 720x480x30Hz (NTSC) then the best is multiplied resolution by 2 or 3, same with refresh.

So it will be 1440x960 or 2160x1440 at 60Hz


But multiplied 60Hz for non interlaced is too low.

At 60Hz screen is not that stable as at 72Hz.


My video card dont want to accept custom resolution 1440x960 (dont know why) and 2160x1440x72 is too much.


So where is the answer?

That Barco is probably best at 1440x960. It may be able to run at higher resolutions but the tubes won't resolve it fully so you'll get line overlap.


The refresh rate should be set for the type of source you're watching.


59.94hz for NTSC video

60hz for PAL

47.952 or 71.928hz for FILM (most can't stand the flicker at 47.952 tho)


Personally I just leave it at 71.928hz for FILM or VIDEO (dont have any PAL). In theory you may see some judder at this refresh when watching VIDEO. You will definitely see frame skips for FILM if you don't run a perfect multiple of 23.976
