Optimizing files for large LCD screen
« on: July 19, 2011, 09:28:53 PM »

I have many more landscape photos than wall space, so I purchased a 60" Sharp Aquos LCD to display my photographs as a repeating slide show.

It has a slot in the back for a USB memory device and plays only JPEG's.

I am wondering how to optimize my files for display.  How large can the files be?  I'd like to have the least amount of compression possible.

Does anyone have any experience preparing files for this LCD?  Is there a color space that works better than others?  What about sharpening?

Appreciate any guidelines from those who have done this.

Thanks.

Why not just load a few high res images as jpgs and try them? It seems like the only issue would be speed of loading/slide show speed. I'm not sure if srgb would be much different on that screen as other color spaces.

My 2c's :

- From what I've seen, playing jpg files on a TV can be quite sloooooow, ie 10s/image, if the TV has to resample large files. The resampling done by the TV may not be optimal either, so 1st thing is to constrain images within the TV native definition (ie 1920*1080 if full HD).

- For color space, as these beasts generally don't know anything of color management, the best would be to profile the TV... this http://www.homecinema-fr.com/colorimetre/index_en.php may help but I never ventured into anything such.
Otherwise, sRGB should be not too far from the ballpark.
