Table 513. VMware Blast Policy Settings (Continued)
Setting Description
Image Quality
Specifies the image quality of the remote display. You can specify two low-quality settings, two high-
quality settings, and a mid-quality setting. The low-quality settings are for areas of the screen that
change often, for example, when scrolling occurs. The high-quality settings are for areas of the
screen that are more static, resulting in a better image quality. You can specify the following settings:
n
Low JPEG Quality (available range of values: 1 - 100, default: 25)
n
Low JPEG Chroma Subsampling (available range of values: 4:1:0 (lowest), 4:1:1, 4:2:0, 4:2:2,
and 4:4:4 (highest), default: 4:1:0)
n
Mid JPEG Quality (available range of values: 1 - 100, default: 35)
n
High JPEG Quality (available range of values: 1 - 100, default: 90)
n
High JPEG Chroma Subsampling (available range of values: 4:1:0 (lowest), 4:1:1, 4:2:0, 4:2:2,
and 4:4:4 (highest), default: 4:4:4)
H.264 Quality
Specifies the image quality for the remote display configured to use H.264 encoding. You can specify
the minimum and maximum quantization values that determine how much an image is controlled for
lossless compression. You can specify a minimum quantization value for the best image quality. You
can specify a maximum quantization value for the lowest image quality. You can specify the following
settings:
n
H264maxQP (available range of values: 0-51, default: 36)
n
H264minQP (available range of values: 0-51, default: 10)
For the best image quality, set the quantization values to within +5 or -5 of the available range of
values.
HTTP Service
Specifies the port that is used for secure communication (HTTPS) between the security server or
Access Point appliance and a desktop. The firewall must be configured to have this port open. The
default is 22443.
Audio playback
Specifies whether audio playback is enabled for remote desktops. This setting is to enable audio
playback.
Configure clipboard
redirection
Specifies the permissible behavior for clipboard redirection. The options are:
n
Enabled in both directions
n
Disabled in both directions
n
Enabled client to server only (Users can copy/paste from the client to the desktop only.)
n
Enabled server to client only (Users can copy/paste from the desktop to the client only.)
The default is Enabled client to server only.
Clipboard memory size
on server(in
kilobytes)
Specifies the server's clipboard memory size value, in kilobytes. The client also has a value for the
clipboard memory size. After the session is set up, the server sends its clipboard memory size value
to the client. The effective clipboard memory size value is the lesser of the client and server clipboard
memory size values.
You can specify a minimum value of 512 kilobytes and a maximum value of 16384 kilobytes. If you
specify 0 or do not specify a value, the default server clipboard memory size is 1024 kilobytes.
This setting applies only to version 7.0.1 and later and to Windows, Linux, and Mac clients on which
Horizon Client 4.1 or later is installed. In earlier releases, the clipboard memory size is 1 MB.
Note A large clipboard memory size can negatively affect performance, depending on your network.
VMware recommends that you do not set the clipboard memory size to a value greater than 16 MB.
