Removing the device is a two-phase process. Then, after having launched the TightVNC control on the remote host, the driver could be automatically and silently installed, directly from the TightVNC viewer “Mirror video driver manager” button. I’ve found just this one https: To copy the driver installation file on the remote host, please verify in the TightVNC remote control configuration General tab , that the box “Copy video driver DemoForge Mirage when installing the service is checked. 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 we suggest is that you consult the test results page on the official TightVNC site at. Using the default configuration, i.

The compression ratio can be set to between 1 and 9, with 1 being “mildest compression” and 9 being “strongest compression”. Using the default configuration, i.

Depending on the remote host OS, you will be probably asked to certify the program via the “publisher verification of the driver software” window. By continuing to browse this site, you agree to this use. JPEG quality can be set to between 0 and 9, with 0 being “worst” and 9 being “best”. Mirror drivers described in this section will install and run only on earlier versions of Windows.


I’ve found just this one https: Where are these changes of display driver architecture described?

Display mirroring technology is widely employed by remote desktop applications such as: Sunday, November 26, 7: This option is not necessarily available on every workstation rfmirage on every operating system. The good news is that the new method is a lot simpler and easier to use than dfmirabe old mirror driver mechanism.

Thursday, November 16, Encoding of screen images It’s a case of playing with the various algorithms that can be used for encoding screen data during transfer.

DemoForge Mirage Driver (DFMirage video hook driver)

Azius Developer Training www. Here are some examples: It is a driver for a virtual video device managed at the DDML level of the graphics system that exactly mirrors the mirrro operations of one or more physical display devices. To perform this compression, processor resources are of course required. The following platforms are fully supported now: A “Display Properties” control panel appears.

DFMirage hook display driver

You should see a noticeable improvement in performance. T hen we rebuilt our Mirror driver with: It’s what you need if you are taking control remotely via a modem or ISDN line.

Moreover, TightVNC itself uses all sorts of compression algorithms to reduce the size of the images going through the “pipe” to the controlling machine. Where is this “new method” remote display driver architecture explained?


There’s clearly no one solution that covers every need.

To setup the DFMirage driver, run dfmirage. When the first phase is finished, the system must be rebooted.

You’ll lose dfmkrage a little on quality, but you will win in terms of required bandwidth, hence speed. What we suggest is that you consult the test results page on the official TightVNC site at.

A detailed explanation of how a mirroring video driver works may be found in the Windows DDK. The main arguments to look at are: The underlying virtual display device uses plug-n-play technology, so the installation requires no reboot.

What can I do? Never try doing this if the workstation has an ATI graphics card: Mirorr purpose of this page is to show you ways in which you can improve your installation, murror the various parameters you can tweak if you want to reduce response time when taking control remotely.
