Supports (MMX/3DNow/SSE accelerated, but still slow) software scaling, use the options <tt class="option">-fs -zoom</tt>. Most cards have hardware scaling support, use the <tt class="option">-vo xv</tt> output for them, or <tt class="option">-vo xmga</tt> for Matrox cards. </p><p> The problem is that most cards' driver doesn't support hardware acceleration on the second head/TV. In those cases, you see green/blue colored window instead of the movie. This is where this driver comes in handy, but you need powerful CPU to use software scaling. Don't use the SDL driver's software output+scaler, it has worse image quality! </p><p> Software scaling is very slow, you better try changing video modes instead. It's very simple. See the <a class="link" href="dga.html#dga-modelines" title="RESOLUTION SWITCHING">DGA section's modelines</a>, and insert them into your <tt class="filename">XF86Config</tt>. </p><div class="itemizedlist"><ul type="disc" compact><li><p> If you have XFree86 4.x.x: use the <tt class="option">-vm</tt> option.
