Can we improve screenshot DPI

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?

screenshots do not have a dpi.

dpi is meaningless unless you print.

that's just a default value because windows assumes 96 dpi (actually
ppi, which is often confused with dpi but is not the same) and nearly
all software ignores it anyway.

To what purpose?

Typically DPI is used for print resolution, and with a good printer for a
good quality print you would be looking for 200-360 dpi.

I am not a Windows, Irfan, or MS Paint user, so you are left with the
experience of a Mac user from r.p.d.

....but why do you need a better resolution than you are capable of?

Screenshots are typically used to the state of a process, or window at a
particular time in that process.
....or if your intentions are a little more nefarious, to pilfer images.

On my Mac I use SnapNDrag Pro which gives me several jpg and png quality
options.

I don’t believe that this is David B. this time.

I could be wrong, but I have a strong suspicion, based on the tone of the OP
post, that this is a different nymshifter known to some of us in r.p.d.,
c.m.i., and m.p.m.i.. I would need to have some sort of proof of legitimate
intent to believe otherwise.

The Wireshark program has a View : Zoom for improving
the appearance of the capture.

I tried some other methods and they failed to impress.

Windows has a magnifier, but it doesn't change the base
resolution, just doubles the pixels.

Wireshark "print to PDF" sucks. Forget that.

Wireshark "font size" setting, forget that.

But the "View : Zoom" in Wireshark menu works OK.
Then try your screenshot again.

Comes from having standards. And because I don't care for fools
trying to be "clever".

Think how much time the world would have saved if people had pointed
out your bottomless stupidity to you so much earlier in your life,
instead of meekly letting you get away with it all the time.

Buy a larger monitor and scale it in GIMP :-)

It's clear from the responses that I was operating under the wrong
assumption how a screenshot gets its resolution.

I thought the resolution of the screen & driver was what determined the
resolution of the screenshot.

If it's not the resolution of the screen & driver, what does determine the
resolution of the Win+PrtScrn PNG screenshot then?

That means nothing. DPI only matters if you want to print.
If it's 300px wide that will probably be about 3 inches onscreen
(though that's not an exact 1-to-1 relationship), but it's only
1 inch on a printer that prints 300 DPI. You can switch the DPI
in IrfanView, but it won't have any effect on the image.

Looking at it another way: You have a picture of an apple
that's 100px square at 96 DPI. You change the resolution
to 300 DPI. It still shows about 1 inch onscreen and it
still prints about 1/3 inch with 300 DPI printing. That's
because the image is always 100 pixels square. DPI is only
the calculation of how those pixels fit into a display medium.
It means nothing out of context.

If your screen is, say, 1600x900px then you can take a
screenshot 1600x900 pixels. There are only that many pixels
displaying, so there's no data to increase the resolution. If
you then switch the display to be, say, 2700px wide, you'll
get more pixels onscreen, but the objects will be smaller!
A 32x32 icon doesn't get more pixels when you increase
monitor resolution. It only has 32x32 pixels of data, no matter
what you do.

So you need to think of it in terms of pixels. The more
pixels, the more data, the more you can enlarge. Which is
why megapixels is so important with cameras. If you want
to get minimal quality print of a photo you need at least
300 pixels for every inch. Thus, if you want to print a
5x7 photo at lowest usable quality, you'll need 1500 x
2100 pixels in the image, or 3+ megapixels. If you want to
print it at 600 DPI you'll need an image 3000x4200px, which
is over 12 megapixels. You can always enlarge the 1500x2100
image, but there's no way to get more data. The enlarging
is just a mathematical formula that adds pixels while guessing
at what color they should be.

....and the resolution, and manner of publication of the original
image/document.

If it's not the resolution of the screen & driver, what does determine the
resolution of the Win+PrtScrn PNG screenshot then?

What is the source of the display image you are trying to capture?
Is it a part of a web page, is it a screen capture of a document such as a
PDF, WP, or spreadsheet doc?

Ultimately you are limited by the native resolution of your display, the
quality of the original, and the intent of the creator of the published
image/document. So I will ask once again; what is your purpose for these
higher resolution screenshots, why do you need the higher resolution?
