<p>In one setup I was pleasantly surpised at how well it worked. Fonts did behave as expected. <br />
Specatcle was able to capture all screens and individual rects correctly.</p>
<p>The less good:</p>
<p>When I switched round the primary monitor all through the GUI and rebooting I had a right mess. The <span class="phabricator-remarkup-mention-unknown">@1x</span> screen fonts were double the size, the <span class="phabricator-remarkup-mention-unknown">@2x</span> screen were 4x the size.<br />
In this setup spectacle had an issue with "current screen" when it was on the non primary. I assume this problem: <a href="https://bugreports.qt.io/browse/QTBUG-64992" class="remarkup-link" target="_blank" rel="noreferrer">https://bugreports.qt.io/browse/QTBUG-64992</a> .</p></div>

<p>That's possible - but unlikely: Except for the logical DPI difference the setups are identical.<br />
What happens with Xft.dpi: 96 and non-primary as 2x?</p>

<p>Yup, that's the WIP part of this diff. Not sure how to do that though, as the code for this is in the frontend and not the (xrandr) backend.<br />
So if you unplug the primary monitor, newly started applications will behave strangely. But then again, this bug is in the current code as well:<br />
If you plug in a new monitor, the scale is 1 (never actually tried that).</p>

<p>It means that plasma uses the scale of the primary monitor (actually the font DPI, but that should be the same). So neither better nor worse than the current state.</p>
<p>With Qt scaling, Plasma behaves as expected: Panels and menus scale depending on the monitor they're on. In exchange, some parts (like window tooltips) appear slightly misplaced.</p></div></div><br /><div><strong>INLINE COMMENTS</strong><div><div style="margin: 6px 0 12px 0;"><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D12405#inline-64825">View Inline</a><span style="color: #4b4d51; font-weight: bold;">davidedmundson</span> wrote in <span style="color: #4b4d51; font-weight: bold;">outputconfig.cpp:143</span></div>
