NVIDIA Profile Setup for Smooth Scrolling (Win7 Only)
Win10 and higher do not allow user configuration of Display Drivers. This article applies only to Windows 7.
If you have an nVidia display card, use the NVIDIA Control Panel, not the Windows display configuration applet, to configure and deploy single or multiple displays for prompting. This article will provide the basics of such a setup using the example of setting up a cloned, dual display using the internal laptop screen and a second display connected to the external VGA output. Connect and power on the external display, then follow these steps.
1. Start the NVIDIA Control panel by RIGHT clicking on your Windows desktop. Select "NVIDIA Control Panel". This will start the applet which should looks something like this figure:
2. In the left pane, click on "Manage 3D Settings" and then, in the right pane, click the "Program Settings" tab. Add your TeleScript software to the list of programs. Click "Add", then navigate to the TeleScript folder, for example: c:\Program Files\Telescript\TeleScriptAV. The "program" file is TeleScriptAV.exe. Once you've added your TeleScript software to the list, you will not have to repeat this step in creating other profiles.
After adding TeleScriptAV.exe (or another TeleScript software product), scroll through the list of settings to find "Vertical Sync" and for the value, select "Force On".
3. In the left pane, select "Setup Multiple Displays" to display a screen similar to this:
Right click on the circle representing the external display -- in this case, the circle labeled "2" is the Sharp LCDTV that is the external display. You'll see a drop down list similar to this:
Extend desktop on this displayDuplicate displays (use Laptop Display as primary clone.)
Duplicate displays (use Sharp LCDTV (substitute your display) as primary clone.)
Identify displays
From the drop down list, select "Duplicate displays (use Sharp LDCTV (your display) as primary clone.)". Click "Apply" to implement this change.
4. In the left pane, click "Change Resolution" to display a screen similar to this:
Though many of today's display cards are sufficiently fast to scroll smoothly at 32bits, the key to a smooth scroll on many computers is to select 16 bit color, particularly when cloning the display. Click on the the primary display (Sharp LDCTV in the example) and move the slider left to 16 bit color. Click "Apply" to implement the change.
5. Finally, save these settings as an NVIDIA Profile. Still on the "Change Resolution" screen, select "Profiles/Save" from the top level menu.
In the "Save As.." dislog, give your profile a name such as "Prompt Direct VGA 1360x768", then click "Save".
NOTE: The NVIDIA Control Panel by default stores profiles at "C:\Program Data\NVIDIA". This folder is hidden in Windows by default. If you would like to access these files with Windows Explorer, see your computer's help files under the topic "Show Hidden Folders".
To "recall" the profile for future use, select "Change Resolution" in the left pane, then select "Profiles/Load" from the top menu.
