If you use a browser or Chrome device that has a high pixel density resolution, such as a MacBook with Retina Display or a Google Chromebook Pixel, you can set the remote desktop or published application to use that resolution. Turn on the High Resolution Mode option in the Settings window, which is available from the sidebar. This option appears in the Settings window only if you are using a high-resolution display or a normal display that uses a scale that is greater than 100 percent.
The High Resolution Mode feature cannot change the resolution for an active remote session. You must log out and log in again to make the feature take effect.
To use the 3D rendering feature, a Horizon administrator must allocate sufficient VRAM for each remote desktop.
- With the software-accelerated graphics feature, you can use 3D applications, such as Windows Aero themes or Google Earth. This feature requires from 64 MB to 128 MB of VRAM.
- The shared hardware-accelerated graphics feature (vSGA), which is available with vSphere 5.1 or later, enables you to use 3D applications for design, modeling, and multimedia. This feature requires from 64 MB to 512 MB of VRAM. The default is 96 MB.
- The dedicated hardware-accelerated graphics feature (vDGA), which is available with vSphere 5.5 or later, dedicates a single physical GPU (graphical processing unit on an ESXi host to a single virtual machine. Use this feature if you require high-end hardware-accelerated workstation graphics. This feature requires from 64 MB to 512 MB of VRAM. The default is 96 MB.
When 3D rendering is enabled, the maximum number of monitors is one and the maximum resolution is 3840 x 2160.
Similarly, if you use a browser on a device that has a high pixel density resolution, such as a MacBook with Retina Display or a Google Chromebook Pixel, you must allocate sufficient VRAM for each remote desktop.
