you can crop it, but you'll lose content and the quality will be lower.

go back and reshoot it.

I was afraid someone might bring that up.
I figured that he'd be chasing a red herring if he
starts getting into screen DPI settings, since it's
just another version of enlarging. And then he's
also likely to get into funky side effects, like
buttons not fitting in windows.

2017: The year we lean to play the great game of Euchre

This is way off topic, but I've been wondering this for many months.
Why do you want to lean to play Euchre instead of learn to play
Euchre?

Did you ever hear of a spell checker. It can make some quite interesting
changes to what you intend to write.

I asked the same question a few weeks ago but nothing changed, so I
figured it was intentional. For all I know, Euchre must be a game where
the players need to lean in one direction or the other during play. I
ignorantly assumed it was more of a traditional card game, where players
are allowed to sit upright. Always glad to learn.

no it won't.

it just changes a tag in the image, which is almost always ignored.

A 'screenshot' captures the screen area you specify! The diff in display of
96DPI to 120DPI is a 25% increase in pixels-per-inch! Maybe your assert "no it
won't" doesn't apply to professional screencapture software because *yes, it
does* on my system!

Aren't image tags are what 'good' photo editing software works with?

I don't these misbehaviors on my system[s]. (I've been running 120DPI since
WinNT!) Maybe it works better on my 1920x1200 display, perhaps?

dpi is meaningless for screen shots.

That's just wrong!
The DPI for the screenshot is *exactly* what the screen DPI setting is. If you
change the screen DPI setting then all subsequent screenshots will be whatever
the new setting is! Ergo: changing the screen DPI setting changes the
screenshot DPI!!!

Like I said.., *not on my system*!

Only matters for high-level image work. You can't add resolution to an image;
-only work with what's already there.

nope. the tag might change, but the tag completely meaningless and
nearly all software ignores it anyway.

screen shots are just pixels. if you set your display to a higher
resolution, you get more pixels in the screen shot. that's all.

ppi (not dpi) only matters when you print, at which point it depends on
how big of a print you make.

dpi is a function of the printer and its settings, not the image being
printed.

In my world the editor works with the image!

Now that's *exactly* what I said!!!

ppi (not dpi) only matters when you print, at which point it depends on
how big of a print you make.

What does the printing aspect have to do with making screenshots?

FWIW
I know exactly how this works and have been working with it for ove 2 decades.
Doesn't seem I'm doing much good here, though, so I'm done with this thread!

Agreed, Once I made a 5,000 dpi image and a 50 dpi image. sized equally
in Photoshop and not one person could tell the difference without
checking the EXIF data. and these were pro competitors on Worth1000 one
of the big Photoshop contest site on the net.

Are y0ou saying that PhotoShop didn't update it's metadata to match the new
resoution after resizing?

Is there any way to snap a screenshot at better resolution than 96 DPI?

I pressed Win10 Windows+PrintScreen which created a screenshot PNG file.
C:\Users\bram\Pictures\Screenshots\Screenshot (666).png

I open it in IrfanView & select "Image Information" which tells me
Number of unique colors = 74425
Current size = 1280 x 1024 Pixels (1.31 MPixels) (1.25)
Current colors = 16,7 Million (24 BitsPerPixel)

That doesn't tell me the DPI so I go to "Image Resize/Resample"
DPI = 96 (auto calc. for cm/inches)

I confirm the dots per inch with Microsoft Paint "File Properties"
Resolution = 96 DPI

Just curious: Is there a way to snap the screenshot at better DPI?

More or less, no. The majority of monitors are 96DPI, period. I've seen
one, back in the Windows 98 days that was able to be set higher. You're
not going to get better.

As has been said repeatedly in this thread and many websites, DPT Dot
per Inch is only valid for the printer when printing to paper. Pixel
are the only valid measure of the picture quality for images displayed
digitally on a screen.

until the next hand was played. ;-)

That replaced an earlier rule where the losers of a hand received a bullet
behind the left ear. That way they didn’t have to worry about the next
hand.

I appreciate that you're helpful since some of the others don't even seem
to understand the question where they think printing is involved or where
they think it matters what you're screenshotting.

The question is just one of what determines resolution of any given
screenshot.

Specifically, how do I increase the number of pixels copied off the screen?

Someone asked "what" I'm taking a screenshot of, where I can't imagine that
his question has any technical merit since it shouldn't matter what you're
taking a screenshot of since the screen is displaying it - so you can't do
better than the screen, right?

Someone else also mentioned printing, which again has no bearing on the
question since the question is only about how to increase the resolution of
the captured screenshot.

Let's say I have a current screenshot resolution of X.
And let's say I want to double that resolution to 2X.

How can a person do that?

They're not going to double their resolution by what they're looking at.
They're not going to double their resolution by printing it.

How can you double the resolution of a screenshot?

Do you change a software driver?
Do you double your screen size?
Do you double your memory?

What determines the resolution of any given screenshot on your own screen?

My ageing laptop screen is 1280 x 800. If I take a screenshot of the
full screen it will give me a jpg of 1280 x 800 pixels. If I take a
screenshot from my other computer I get more because it has a finer
resolution screen, eg 1600x1200.

What gets written into the DPI field of the EXIF info depends on what
software was used to take the screenshot and bears no/little
relationship to that actual pixel size. For instance the software I
use to take screenshots just puts 96DPI into the EXIF, regardless
though for my screen it isn't actually that far off. (13.25" x 8.5"
approx).

If you get a magnfying glass or magnifying software you can see the
individual pixels on the screen and count them up. Unless you then
upsize your image (which means creating pixels that weren't already
there) or downsize (which means condensing the pixels that are there)
you cannot change the screen print resolution because it is fixed by
the screen you have.
