Explain image resolution vs. native resolution?

<p>Is it true that one should set a monitor to a monitor's resolution with the formula <strong>monitor's optimal horizontal pixel resolution/width of monitor screen</strong> <strong>in inches</strong>? Is so, can someone explain why this is important in terms of printing, doing post-processing work, or displaying jpeg files on the internet. I did read an explanation, but it was confusing to me. Either the explanation wasn't clear and succinct or I was very tired when I read it.</p>

<p>Thanks</p>

<p>It has nothing to do with printing really. About the only correlation I can think of would be using Photoshop's <em>View>Print Size</em> command which isn't very useful (got pulled out for awhile) and doesn't work<strong> at all unless</strong> you first set the correct size for pixel dimension of your specific display into the preferences. I'd ignore all this stuff ;-)</p>

<p>If you have a LCD screen, set the screen resolution to its native resolution. Every other resolution will look worse. Making screen size match print size exactly sounds like a very useless exercise.</p>

I think you are confusing two good pieces of advice

1) your display should be set to its native resolution.

2) in Photoshop, under general settings, take the width of the screen as measured in pixels and divide thatby the physical

width as measured in pixels to set its resolution. So if the screen has a horizontal resolution of 2000 pixels and the live

area of the screen is 20 inches wide, you set photoshop for 100 pixels per inch.

<p>Ellis, what version of Photoshop can you enter pixel resolution under "General Settings". I'm not finding where to enter this in any of CS5 Photoshop General Pref dialog box settings.</p>

<p>Tim, I think it's in Preferences > units and rulers > screen resolution.</p>

<p>Changed the Screen Resolution under New Document Preset Resolution in Units and Rulers and it doesn't have any affect on size or appearance of sharpness after making a new document or opening a photo. Didn't change the ruler size turning on rulers in the new document either. I even quit and restarted Photoshop.</p>

<p>But thanks anyway for the tip, Adrian.</p>

<p>Alan, I am not sure I fully understand your question. Anyhow, I found an article that explains <a href="http://www.vsellis.com/understanding-dpi-resolution-and-print-vs-web-images/">screen/web vs print resolution</a>. Hope this helps.</p>

<p>Tim, After specifying the screen resolution in Prefs, you can then use the View->Print Size option to display an image at its default print size, as shown on the Image Size dialog - i.e. the "Document Size".</p>
