Re-sizing

A question for you all regarding re-sizing images. I usually shoor RAW and create JPEG files in pp. I usually resize them during pp to 1080 pixels on the tall side because that equates to my monitor resolution. This means that any pictures I use as a screensaver will display correctly and also keeps the overall file sizes not too large. My understanding has always been that it is best to resize for the screen the picture is to be viewed on, then apply output sharpening (USM). Am i right in thinking that if I left the original pixel dimensions (7360/4912) that when viewed on a screen the image would lose some sharpness as the computer software would be drastically reducing the image for viewing ? From doing some tests this is what I think happens. The reason I am asking is I am doing some portraits of a friends dog. most of the images will be viewed on her monitor/ipad and uploaded to facebook etc. But she also will want to use an image or two to have some physical artwork made up (poster style). I assume that for the latter keeping a large pixel resolution image would be best. So do i supply all the images at full size, or supply all the images at a sensibly reduced pixel size (say 1080 tall or a bit bigger to account for most monitors) , and then supply full size images for only those ones she wants to have artwork made out of. I guess what I am asking is what a professional photographer would supply a client in this circumstance, although there is no commercial arrangement in my case.

FastStone Image Viewer can display and resize both jpgs and DNG files, and has a very simple and quick resizing process - I use it a lot.

K-3 II, K-3 and a K-70 from SRS (having now relegated the K-30 /"K-50" to a backup body), & some Sigma and Pentax lenses (and a lot of old 35mm gear!)
