In Horizon 7 version 7.0.1 and later and Horizon Client 4.1 and later, the clipboard memory size is configurable for both the server and the client.

When a PCoIP or VMware Blast session is established, the server sends its clipboard memory size to the client. The effective clipboard memory size is the lesser of the server and client clipboard memory size values.

To set the clipboard memory size, modify the Windows registry value HKLM\Software\VMware, Inc.\VMware VDPService\Plugins\MKSVchan\ClientClipboardSize. The value type is REG_DWORD. The value is specified in KB. If you specify 0 or do not specify a value, the default client clipboard memory size is 8192 KB (8 MB).

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.
