The purpose of this page is to show you ways in which you can improve your installation, explaining the various parameters you can tweak if you want to reduce response time when taking control remotely. Moreover, TightVNC itself uses all sorts of compression algorithms to reduce the size of the images going through the “pipe” to the controlling machine. For DOS applications, it’s a little less sure. Using in conjunction with Zebedee As is the case with all tunneling software, packets are compressed before sending them through tunnels. However, be careful because known compatibility problems may arise in some configurations and OS read more. You should see a noticeable improvement in performance.

This is the default value and the argument that gives the lowest transferred data volume. Hardware acceleration One trick you can try, if for example the remote station is a server, mirtor to completely deactivate hardware graphics acceleration. Uninstallation The uninstallation of DFMirage is fully supported. Encoding of screen images It’s a case of playing with the various algorithms that can be used for encoding screen data during transfer.
dfimrage When the first phase is finished, the system must be rebooted. It’s what you need if you are taking control remotely via a modem or ISDN line. Consequently, if you use Viveo in conjunction with Zebedee inside your local network, we advise you to modify the contents of the following file: It is a driver for a virtual video device managed at the DDML level of the graphics system that exactly mirrors the drawing operations of one or more physical display devices.
Removing the device is a two-phase process.
Please feel free to ask any questions about our products by e-mail.
Installation To setup the DFMirage driver, run dfmirage. JPEG quality can be set to between 0 and 9, with 0 being “worst” and 9 being “best”. This tool requires processor resources.
Mirroring is a technically superior method when compared to primitive screen grabbing, because it allows the capture of only the minimally updated regions and retrieves the data directly, bypassing the intermediate copy. What can I do to improve it? The uninstallation of DFMirage is fully supported.
You need to check out rfmirage presence in each case. Example of some command line combinations: You’ll lose out a little on quality, but you will win in terms of required bandwidth, hence speed. Using the DFMirage video hook driver solves the problem of reliably and efficiently detecting modified areas on the screen.
What we suggest is that you consult the test results page on the dfmiragw TightVNC site at. Maximum compression, minimum volume. It will however cause a fair amount of latency due to the compression and expansion stages.
The following platforms are fully supported now: Also concerns the following software: A “Display Properties” control panel appears. If there was, we would have implemented it!
Never try vidwo this if the workstation has an ATI graphics card: This driver may be used transparently with office, CAD and other types of business and utility applications. To do so, click on the Windows desktop with the right mouse button and select Properties. Confirm the setting by clicking OK both times.
