![]() ![]() This does, however, mean that the mouse pointer cannot leave the confines of the VNC Viewer. With direct mouse control being diverted, this gives you precision mouse control of the remote host computer. The single mouse mode feature redirects the mouse movement from your local desktop environment and channels it directly into the VNC Viewer. Make sure that the desktop resolution on the host computer matches this resolution. Typically at the top of the Video Settings menu, you should see the screen resolution that is being received. You can check the video resolution that the VNC Viewer is receiving from the host by opening to the Controls menu and navigating to Video Settings. If neither of these is possible, then as a workaround you could try using Singe mouse mode. You could either match the screen resolution that the graphics card is outputting or see if there is a setting on the graphics card to prevent it from upscaling. There is no simple way to fix this problem as it is the graphics card that is upscaling the video. So if VNC is calibrating for 1600x1200 which is being received but the actual desktop is set to 800圆00 then it will fail. The consequence of the upscaling is that the mouse calibration measures the movement of the pointer based upon the screen resolution that it is receiving. For example, if your desktop resolution is set to 800圆00 but your graphics cards resolution preference is for 1600x1200 then the graphics card will automatically upscale the desktop to 1600x1200, but you would not notice any visual difference. The graphics card can upscale the desktop resolution to its preferred higher resolution. Graphics cards typically have a preferred resolution that they like to use, which in part is defined by attached monitors capabilities. Check that the desktop screen resolution matches the resolution that the graphics card is outputting. This only affects hosts that are using an analogue (VGA) output. Scaled Video Output (Analogue Video Only) ![]() Untick the checkbox and press OK on the Mouse properties window to commit the change. ![]() Under the Pointer Options menu, in the Motion section is the option Enhanced pointer precision which is ticked by default. #Vnc viewer for mac home end key windows#Open the Windows Control Panel and find the Mouse settings. On Windows, there is a mouse setting called Enhanced Pointer Precision that when enabled can cause the remote mouse pointer to drift. Move any icons or objects in the top left corner of the screen that might change colour when the mouse pointer is over them. If anything changes during this process in the area where it is being measured, like the highlight of an icon, this can cause the calculations to fail as the mouse pointer position cannot be determined. ![]() There are a number of reasons why your local mouse pointer on the VNC Viewer may not be calibrated with the remote hosts pointer.Īs part of the mouse calibration process, the mouse pointer is moved to the top left-hand corner of the screen, moved a few pixels and measured. If the calibration failed or you find that the remote mouse pointer is drifting away from your local pointer then the troubleshooting steps below should help to resolve the problem. After the process has completed, you will be either told that the calibration was successful or failed. Click on the appropriate button to begin the mouse calibration process.Īlthough not seen on your VNC Viewer, the process goes through a number of steps to measure the movement of the mouse pointer. The window that appears next varies between our different VNC products. To calibrate the mouse, click on the calibrate icon (cross) on the toolbar to start the calibration process. If you are using an analogue VNC product, you can also automatically calibrate the video. Moves the remote point to the top left-hand corner of its screen.Ĭalibrate Mouse and Video (if using an analogue VNC product)Īllows you to calibrate the mouse pointer. ![]()
