Looking at images at home I may be using 4 screens of different set up and type at different type, should we be going less extreme?
I realise now that using sharpening export from lightroom needs to be checked and may overdo what has carefully controlled in your editing.
Any other tips on difficult images?
Well, there's nothing technically wrong with using a smaller image. However, when projecting we don't enlarge or reduce files that have been submitted, because that might mean altering the apparent sharpness of an image. It's a choice to be made by the author - a smaller image will mean it occupies less screen space; a larger will mean it'll be cropped to the screen size. Unless you have an extreme crop-in to your picture, it's unlikely that you'll run out of pixels when reducing, given the sensor size of most cameras these days.
If a picture is missing bits when projected, this will be because it is either taller or wider (or both) than the 1920 h x1200 v of our projector - it's as simple as that. If the image is less than those dimensions, nothing will be missing. If you're referring to the recent Zoom meetings, make sure that your Zoom video is setup to "fit to screen" (dropdown choice, top/middle of the Zoom screen)
I don't quite understand the q. relating to 4 different screens. If they are all different resolutions, and you show them at native resolution (i.e. 1 pixel in the image means 1 pixel on the screen) then they will all be shown at different sizes. The way around that is to Zoom to fit every screen, though this might mean pixel replication or destruction, depending uponthe screen res. What do you mean by 'going less extreme'?
Never 'sharpen for screen'. Do what you want to the image as if for printing and just size it downwards only, never upsize it: if you have to do the latter, the image is probably too small to start with.
