I am using LR slideshow exactly as I did in LR 5 where it always worked successfully. Now with LR 6, I type in standard text in the Metadata Caption space, no special characters, on most photos in a folder. Then I put the folder in Slideshow mode. When I Export PDF Slideshow, each photo is displayed with its corerct caption. When I Export JPEG Slideshow, each photo is displayed with the last photo's caption in the folder. I tried everything I know to do including removing the caption in the last photo. Then only the " " marks are displayed for each photo where the caption should be. This is very strange. The JPEG slideshows are usefull for me when I want to project a slide show from another computer or flash drive, or print individual photos with the caption. Thanks for any help you can suggest.
The "Use Graphics Processor" is unchecked, but I don't calibrate my monitor.
I'm not seeing the banding in any of the LR modules, only in the exported videos. I took the computer to my computer guy who upgraded my video graphics card last summer to see if it was the relatively new graphics card causing the problem. He used his own monitor and ran several small mp4 video exports of some of my pictures using different video graphic cards. Each export resulted in color banding on random slides.
For the presentation, the projector (an old Infocus) was connected to the computer where the monitor had been connected. The detached monitor cable was plugged into the projector so I could watch on my monitor what was displayed on the projector screen. Again there was no color banding as I was playing it right from LR on my desktop computer.
