<p>I am also having this problem, but when testing on a normal monitor. Monitor is at 1024768, laptop at 1024600.</p>
<p>I am using Ubuntu Lucid Lynx, 10.04, with the PPA version of OpenLP version number in Help -> about is OpenLP 1.9.0 build bzr000. And I estimate that the white bar, not grey for me, is about 168 pixels high, as if the output is the same size as the primary monitor.</p>
<p>I tried setting the resolution of the laptop display to 800*600 and restarting OpenLP but I still had the same problem.</p>
<p>Any help would be appreciated.</p>
