Screen resolution query

[Alexander.Of.Oz]

I could probably find the answer to this out on the interwebz, but thought I'd ask it here.

With the new wave of monitors upon us having higher Pixel Per Inch ratios, do I now need to present my images at a higher PPI rate than 72 for them to appear with fine detail to those viewing on the denser PPI ratio screens?

When I view my images on my iPhone 8 Plus, they appear perfectly fine at 72PPI and it has a much higher PPI than 72, so I'm a tad perplexed by what I initially thought was a logical presumption in the need to increase this.

Thanks in advance for any clarification you all can offer in this regard to me.

Nope PPI applies to print only I believe. All you need to remember is the resolution of the displays people are looking at now so if you exported so your images would fit on a 1080 screen, now for uhd etc they need to be higher resolution to fit natively.

Thanks, Ken!

That's where my confusion set in with this thought. DPI refers to Dots Per Inch for printing and PPI is the Pixels Per Inch for screen resolution. I always print at 320DPI or higher if I'm going for a fine art finish.

I offer my images I present here at 1600 pixels across (in landscape mode), if someone clicks on them, at 72PPI. Which for my current 27" (2560x1440) monitor is a fair sized image. But, I have no idea how this is presenting for those with newer higher density PPI monitors.

Where my confusion stems is that even this monitor presents at a higher than 72PPI ratio, it's just over 100PPI actually. Yet my jpegs presented at 72PPI appear perfectly crisp and detailed!

So is it just that I need to present them at larger pixel width sizes for those with newer monitors, or do they also need a higher PPI ratio to present clearly?

The reason for this is that web browsers and other image displays totally ignore DPI and PPI. All that matters is just the pixel count. Why? Because in order to "PI" (per inch" to be meaning fall the software in the computer would need to know the physical size of the monitor and it does not. The only units it uses is just "pixels"

In terms on clarity of detail all that mattress the number of pixels in the image.

Thanks so much, Chris. That makes sense now!

I’ll keep posting at 1600px wide then.

Sorry mate, I wasnt notified you replied...

Yes what the other guy said...

It is pixels pixels or pixels that matters... if you display at native resolution for the monitor, you get the best image as the display is not up or down scaling. However, the browser will mangle it as needed to scale for its displayed size. for example when facebook knackers my beautiful skies!

So just focus on resolution.

Gotcha! Of course! Not everyone has their browser open as large as mine! Facebooks algorithms are terrible for compressing the heck out of the fine details, and to me it appears to be worse in the highlights. I'm glad to be posting my images from SmugMug where it doesn't touch my colours or over-sharpen things.
