title: How to connect in full screen mode to Linux CentOS 7 virtual machine?
body: <p>I'm connecting to CentOS 7 VM from Hyper-V from Windows 8.1. The full screen mode is not working. I need to fix that. Other VMs including CentOS 6 and Windows Server have no problems.</p>
  
  <p>These are some observations I made when I connect to that VM from Hyper-V Manager.</p>
  
  <ol>
  <li><p>CentOS 7, while booting, displays this warning "fast TSC calibration failed". I read that this is not a problem but I'm not sure. Everything else is working in the VM except not being able to work in the full screen mode of my laptop which has a pretty high resolution graphics card.</p></li>
  <li><p>Applications -> System Tools -> Settings -> Displays shows only one default option "Built-in Display" with grayed out Resolution of "1152 x 864 (4:3)". This is where I was expecting to see other resolutions to choose from!</p></li>
  <li><p>When I run the following bash command</p>
  
  <pre><code>lspci -nn | grep VGA
  </code></pre></li>
  </ol>
  
  <p>I get </p>
  
  <pre><code>    00:80.0 VGA compatible controller [0300]: Microsoft Corporation Hyper-V Virtual VGA [1414:5353]
  </code></pre>
  
  <p>Any help would be greatly appreciated.</p>
