InDesign/Powerpoint to JPEG for 50" widescreen monitor viewing
I'm trying to export a file (either InDesign or PowerPoint) that can be exported to a JPEG to be viewed on a 50" widescreen monitor off of a thumb drive. There is no computer attached, it is a smart TV. I have changed the export resolution in powerpoint and the final image still gets extremely degraded and pixelated. And I have created the largest format in InDesign and exported but coming back with the same results. Any suggestions or help is greatly appreciated. Thank you!
It is likely that you are exporting an image that is very small and it is getting scaled up by the TV and therefore looks terrible.
If the TV is HD (likely) then it is natively showing a 1920x1080 pixel image. So for best quality, you want to export a 1920x1080 image at 72 dpi (which means 1:1 pixel ratio â€” show 1 pixel of image in 1 pixel of TV screen.)
Before you export, change the size of the InDesign/PowerPoint canvas to 1920x1080 at 72 dpi. If in InDesign, make sure you are also in RGB color mode.
Look at the InDesign/PowerPoint canvas and make sure the image is composed in the way that you want. You may have to scale up the elements on the canvas to fit the canvas size. Hopefully any text is in text blocks (not bitmap images) so that when you scale it up, it scales gracefully.
When you have the image that you want to see on the TV, export as JPEG without scaling up or down.
