<p class="MsoNormal">Otherwise, if you use the nightly binaries or paraview/master, you can tweak your launcher config to use pvbatch instead of pvpython which leverage a true offscreen rendering which will be then independent of the screen resolution. But
you will need to set the following environment variable. <span style="font-size:10.5pt;font-family:"Arial",sans-serif;color:black">PV_ALLOW_BATCH_<wbr>INTERACTION=1</span><u></u><u></u></p>
