Works ok for my purposes, especially if you crank saturation slightly up with VLC filters or Nvidia settings. The native resolution of the M22 is 1280&#215;800, but unfortunately Linux does not detect it automatically, giving maximum 1024&#215;768 pixels instead (yes, I&#8217;ve tried several different computers and cables). Luckily there are two solutions that have solved the issue. Firstly, using an HDMI to VGA converter will solve the detection problem. The other way is to force the resolution with some command line magic:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">xrandr --newmode \"1280x800\" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync<br>xrandr --addmode VGA1 1280x800<\/pre>\n\n\n\n<p>Depending on your setup the output name might not be VGA1. Typing plain <em>xrandr<\/em> will tell you what&#8217;s connected. After the two lines you should see the new resolution in your favorite screen mode selector and also the <em>xrandr <\/em>list. Either use the desktop environment facilities or do this:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">xrandr --output VGA1 --mode 1280x800<\/pre>\n\n\n\n<p>As a final tip, and so that I remember it myself in the future, the <em>cvt<\/em> command line tool conveniently calculates these modelines for you (there is also <em>gtf<\/em> which does exactly the same thing). There&#8217;s <a href=\"https:\/\/arachnoid.com\/modelines\/\">this<\/a> online, too.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I have an ASK Proxima model M22 at my disposal \u2013 already an old HD projector with VGA as the main input port.
