Remote Desktop


Desktop Sharing

Choose stream quality

You can select from two different streaming options (you have many more to chose from the ISL View Toolbar once the session is established), selecting either Stream in high speed - stream quality will be decreased to reduce latency and create streaming as quick as possible or Stream in best quality - quality (resolution/color depth) will be maximized, if the connection is fast enough this provides the best working experience, but with slow connection you can expect some latency to occur. 

Default value is: "High Speed"

Leave font smoothing while sharing this desktop

Set whether or not the font smoothing effect on the remote computer is left enabled during the session or if it should be disabled once the session starts. 

Leave background while sharing this desktop

Use this option to remove desktop background when streaming. If you check this option, it can have a noticeable impact on performance since more data will need to be transferred when a window is moved. If left unchecked then the background will be set to solid black for the duration of the session. 

Default value is: unchecked

Leave desktop effects while sharing this desktop

Similar to removing the background image for the duration of session it is advisable to disable other desktop effects as they are purely aesthetic but can have a great impact on the quality and speed of remote support session, especially if the connection has a limited bandwidth. 

Default value is: unchecked

Leave AERO desktop experience while sharing this desktop

Use this option to disable the AERO style setting in Windows (purely aesthetic addition of Windows). This option is checked by default and if you uncheck it, it can have a noticeable impact on performance since more data will be needed to be transferred when a window is moved. You can read more about AERO styles here

Default value is: unchecked

Lock computer when network connection is lost

Set if the remote computer should automatically be locked if an ongoing ISL Light session gets disconnected.

Black screen stop delay (in seconds) when ESC key is pressed

Specify the amount of time (in seconds) that takes the Black Screen to be removed after the Esc key is pressed. Valid interval is between 10 and 300 seconds.

Default value: 10

On Session Start

Enable Black Screen when user connects

This option enables the use of Black Screen option while in session. If you or your client needs more privacy, you can request the Black Screen to be displayed on the client side. During the time that the Black Screen is displayed, the user on the remote side won't be able to see his screen, but he can turn the Black Screen off and regain control. 

Default value is: checked.

Enable clipboard by default when viewing remote desktop

Set whether or not the shared clipboard between local and remote computer is enabled or disabled by default when session is established.


Disable local inputs while sharing this desktop

This option takes effect when you are the streaming side of the support session. By selecting it you set that all local user inputs are disabled once the operator connects to this computer. It allows the operator to work on your computer without any disturbances. 

Default value is: unchecked

Keyboard combinations passed to other side unchanged

Input the key combinations that pass to the remote computer without being locally translated into a UNICODE character. (e.g. on QWERTZ keyboards the key combination Ctrl+Alt+W results in | character. If you leave this option empty, then | character will be sent to remote computer, otherwise if you set this key combination to pass unchanged, then the remote side will receive key commands Ctrl + Alt + W which may translate into some other character on remote computer).

Input method:

  • All keys are preceded with: VK_
  • All key combinations entered should be in capital letters
  • Supported Keys:
    • characters A-Z ( VK_A, VK_B, ...., VK_Z)
    • numbers 0-9 (VK_0, VK_1, ...,VK_9)
    • Special characters:
      • VK_ALT
      • VK_F1, VK_F2, ... VK_F12
  • Keys combinations are created with + sign , multiple combinations are separated with ,
  • Example: VK_ALT+VK_F4, VK_CTRL+VK_ALT+VK_Q


Stream only non-alpha windows (CAPTUREBLT)

The viewing controls whether the CAPTUREBLT flag will be set for getting server updates. It is used for enabling / disabling the transfer of transparent windows. It is also used in situations when the mouse cursor on the viewed window is not seen (problem has occurred mainly in some Citrix/RDP environments). 

Default value is: unchecked

Select desktop streaming method

Select which driver should be used for acquiring and refreshing the image of the remote display. You can choose between:

  • Automatic
  • Use "Desktop Duplication"
  • Use "Polling"

Default value is: Automatic, allowing ISL Light to select the best option for this session. You can also choose between two other options. 

Polling is a standard way of requesting screen updates from remote machine. 

Display Duplication provides a better remote support experience. However it can only be used on Windows 8 and 8.1, which include new DXGI desktop duplication drivers instead of older XDDM display drivers.

Manage hardware acceleration settings

Select this option to improve video/graphic streaming quality when you are connected to the session. 

Default value is: checked

Use "Desktop Duplication" on Windows 8

If this option is selected, then the new Desktop Duplication drivers will be used if the session is established with a computer running Windows 8 and higher, as this provides a better remote support experience. 

Default value is: checked

Use "Magnification API" on Windows 8

If this option is selected, then the new Magnification API is used when displaying the Black Screen on a computer running Windows 8 and higher.

Default value is: checked

Use deprecated monitor off signal 

If this option is selected, then ISL Light can use deprecated Windows "SC_MONITORPOWER" API to enable black screen feature.

Default value is: checked
