The display resolution of the logrus has been 1064x768 and has been the only option, which is not great. While remote access to logrus using rdesktop allows rendering a virtual display of user's chosen resolution, it is not fast when using graphic-intensive program. NoMachine allows user to take over and control the machine remotely and thus appears as the same machine. However, NoMachine cannot render a virtual display like rdesktop. This has been limiting the resolution of using logrus via NoMachine.

On Friday, I found that even though we had NVIDIA Quadro P600 graphic card installed, we were not actually using it. The monitor has been connecting to the the integrated VGA display connector. This uses Microsoft Basic Display Adapter which limits the the resolution. Today I got a HDMI to Mini-display cable to connector the monitor to the Nvidia graphic card. Then in Display settings, go to Graphic settings, then enable Hardware-accelerated GPU scheduling. After restarting the machine, the machine recognised the Display 2using the Nvidia Quadro P600. In multiple displays field, selected "Show only on 2" and remove the VGA connection to the monitor. Logrus is now set at Nvidia Qadro P600 native display resolution of 1920x1080. This is now also the display resolution in NoMachine.
