Hi all,

on the 23rd i am having a barco tech over to calibrate and fine tune my barco 1208s/2. However, since im running everything from a linux machine he can't really tweak what resolution and hz im feeding the projector, this is up to me.

I'v been searching my behind of trying to find recommended hz settings for 1920x1080, im currently running 1920x1080@48(k?)hz, why? i don't really know, i only know that when i used to use CRT monitors i used to run them way higher than 48(k?)hz.

Some poeple i have spoken to have told me that it depends on what you use the projector for, movies, data etc. I use this projector purely for hddvd/bluray and dvd watching, (i have a mixed collection of NTSC imports/PAL movies) and -everything- is run from the htpc.

I have a linux htpc with a gf9750 feeding a analog signal out through a dvi cable thats split into RGB-HV connectors. (from marcuscables.com)

Could anyone please give me any guidance in what frequency i aught to feed my projector with?

Best regards // max

Running the projector at an even multiple of the source media's frame rate will prevent motion artifacts caused by rate conversion.
For example, if you take 24 frame per second film sourced material and display it at 60 Hz (60 frames per second) the software must play silly games such as displaying one frame three times and the second frame two times, then repeating for frames 3 and 4 ad infinitum. ("3:2 pulldown" IIRC... pulling this from memory.)
If you show film source at 48 FPS then every frame is displayed twice... 72 FPS then every frame is shown three times. This prevents software silliness and resulting motion artifacts.

Note that video sourced material is almost always 30 FPS, so you would be well served to set X modes for 1080p72 AND 1080p60 and have your calibrator set up both of these. Switch resolutions (and memory blocks in the 1208s2) depending on the form of the source media.
