I have an Asus Zenbook laptop, running Windows
8.1. Screen resolution is set to 1920x1080,
which is the recommended size. There's no
external monitor, and I've never connected
one.

But programs are not seeing that resolution.
For example, I used a test image in Irfanview,
and a 1280x720 image took up the whole screen
exactly. (Irfanview is set to show images at
100%.) I don't have Magnifier running, or
anything like that.

It took me a while to recognize this, because
the screen looks really sharp and crisp, but
as far as I know it's been this way since I
got this laptop

When I maximize a window, it takes the visible
screen and doesn't overflow past the screen
limits.

This is Windows 8.1. Intel HD Graphics 5300.
When I bring up Intel HD Graphics in Control
Panel, display settings are Basic and
Advanced, but when I click Advanced it says
this display doesn't support any advanced
settings.

In Device Manager, the laptop's monitor is
listed as "Generic PnP Monitor".

I googled for this, but all I found was advice
to right-click the desktop and select screen
resolution. My screen resolution is correct.
Out of desperation, I tried setting it down to
1600x900 and then up to 2910x1080 again, but
that didn't help.

If anyone can shed any light, I'll be
grateful.


My guess is, your "DPI" is set to 150%, in an
initial attempt to make fonts bigger. In WinXP
days, you dialed "DPI" to make the fonts in
dialog boxes a bit bigger. Even if some of the
letters dropped off the side of the dialog box :-)

Now, Windows has a separate control for letters in
title bars and so on. But I'm still a bit confused
about what the global DPI control is supposed to do,
and why does the odd application seem to be doing the
wrong thing. The DPI setting is applied to more than
a few dialog fonts now.

Applications like Firefox, have at their disposal
physical screen info, as well as virtual screen info
(the ratio of which is "DPI"). And may report the
wrong thing. Causing content of the wrong size to
be delivered from web sites (such as one News site I
use here, where the Flash videos are too wide).

My suspicion is, developers don't know what they're
supposed to be doing with this info. Even in Linux,
I see people fighting with "HiDPI" issues.
