Photoshop’s Resolution Setting & Physical Screen size
Adobe’s Article: “Our Guide to PPI (Pixels per Inch) and Pixel Density”
Adobe recommends customers use Resolution Sizes as follows:
QUOTE:
Here are a few rough PPI measures you can use for your project.
High-res pixels per inch.
High-res displays can handle more PPI on screen than the commonly held 72 PPI standard. If you’re displaying images or film on a large HD monitor, you can afford a far higher PPI level than your average laptop.
- A high pixel density can range between 100-140 PPI
- A very high pixel density starts off at 140 PPI
- High Pixel Density: A high pixel density can range between 100-140 PPI
- Very High Pixel: A very high pixel density starts off at 140 PPI

However, I do not think that the article considers the physical size of the display and the upscaling performed by the manufacturer which causes pixelation that makes the image quality unacceptable.
The difference between a resolution setting of 100 vs 300 is roughly only 5MB additional file size, or slightly more computer space required. However, the difference when those two images are displayed on a 55-inch display (the average size in USA for TVs purchased during the last 5 years) is very noticeable.
Have I missed something? If not, then perhaps the article should be updated.
Why? Data Loss: Using 100 resolution vs. 300 resolution results in data loss roughly of 86%. Only 14% of the original data remains.
Big Screen Displays and 11 x 14 Prints: This is particularly important if showing an image on a 55-inch display or larger, or making an 11 x 14 print.
Above numbers will vary depending on the content of the image: what is in the photograph
What am I missing?
