Recently I realized it would be easy to stream image slide shows on a 60" HD monitor (Vizio E60UD3 TV) located in a fairly large family room. These are essentially screen savers when the home theatre system is used for music. I change the slide show every few days.
Viewing these images has been an educational experience. At typical viewing distances I see elements of composition and content I had not seen viewing them on a 27" desktop monitor.
Here's what I learned.
In the future I will view large images before I send any files off to be printed.

I spent some time organizing thousands of images into genres and series. Some of the older images were re-processed as needed. I then selected sets of 80-100 images to create a dozen unique slide shows. I tried to be ruthless during the selection process. I viewed large images to complete the selection process.
The 3:2 aspect ratio images display at 45" X 29" (114 X 74 cm) landscape and 19" X 29" (48 X 74 cm) portrait. Cropped 4:5 and 1:1 aspect ratio images scale accordingly.
I created high quality, sRGB JPEGs with Lightroom (Camera Raw 9.1.1) using. The image pixel dimensions are 1920 X 1080 (~2 megapixels) or 1920 along the longest image dimension for other aspect ratios. This matches the native TV's pixel dimensions. I have not experimented with doubling the pixel dimensions which the TV can scale to UHD (pseudo 4K). The desk top monitor (Apple Cinema Display) was calibrated using the standard OS X tools. The TV display was not rigorously calibrated. The TV display parameters were slightly modified to optimize highlight and shadow region detail. This did not seem to affect digital video content viewing.
The images for each genre were manually ordered in LR Collections to achieve diversity and attempt an eclectic style. The Collections were exported into individual folders and then imported into the OS-X Photos app as Albums. The Photos app was configured to upload these albums to iCloud. Now the individual albums appear in the Apple TV iOS Screen Saver menu. The selected album set is downloaded in real time to a 4K Apple TV and then sent to the TV display via HDMI.

Here's what I learned.
- Some images just don't work well at large viewing sizes. Others work much better. This surprised me.
- Content, composition detail issues and sub-optimal aesthetic rendering decisions are much more obvious. Images that would benefit from a slightly different crop or cloning out superfluous distractions (e.g. a partial view of street light in a frame edge that appear to hang in space) are much more obvious.
- Converging verticals and transverse chromatic aberrations are more annoying at larger viewing sizes. For a while I used Nikon AI, AIS, AF-S and G lenses. These all exhibited significant lateral CA (red-green fringing) for out-of-focus objects. I find images from Zeiss ZM and FUJIFILM XF lenses to be much better than the Nikkors.
- Even though portrait mode images have about half the display area as landscape mode images, they are not compromised.
- The 4:5 and 1:1 format also work well despite not using even more of the TV display area.
- Composition for images with very deep shadow regions at the frame edges are compromised due to the unused display area's black background.
- Grouping similar images as diptychs or triptychs to use more or all of the 16:9 display is useful.
- Many of the images were scanned from 35mm negatives. Many of these are from ISO 800 film(FUJIFILM Superia). Some are from Tri-X. I feel the film-grain aesthetics are significantly more pleasing compared to desktop monitor viewing. Images I might mot consider printing based on the desk top display couldprint well based on the TV display. This was a pleasant surprise.
- Film images rendered from VueScan raw tiffs scans are superior to high-quality JPEG scans from a lab.
- Color hue, image contrast, highlight and shadow region rendering detail is well-retained even though I did not bother to use more sophisticated rendering calibration tools.
- Some monochrome images require a slightly different rendering approach compared to viewing on a desk top monitor. Film scans display much better in terms of grain. The same is so, but in a different way, for digital monochrome as well.
In the future I will view large images before I send any files off to be printed.
