What version software should I have?            

If you do not have version 4.31 or greater on your supplied software disk, please download it here.

Do I have to install the software?                     

NO! No, software is required to use any of AITech's scan converters.  The software is NOT a driver - it is a screen control utility that allows you to do some screen positioning and sizing only.  If you install the software do not do the "Update Driver Now" option - continue using the default "Update later" option.  The only time you will need to install the software is if you want to use the scan converter in a PAL country. See also How do I use my scan converter with a PAL TV?

What is the software for?                                

Your scan converter software gives you the ability to adjust the position of your screen resize the screen if necessary.  It is NOT necessary to install  this software to use your scan converter. If you install the software do not do the "Update Driver Now" option - continue using the default "Update later" option.  The only time you will have to install the software is if you want to use the scan converter in a PAL country.  See How do I use my scan converter with a PAL TV?

How do I use the software?                            

The software will install the control dialog box card TV OUT in your Display Properties (see below).  In most cases you will not need to use these controls. Refer to your manual on using these positioning and other buttons.  It is not necessary to use the TV OUT button as you will make the settings manually so you can change them back when you need to.

The software will also install a listing in your START/PROGRAMS menu (see below). If you decide that you need the sizing option to make your image fit better on your TV you can use this option.  When you click on Update Display Driver your setting of 640x480 will be changed to 600x440 to better fit the image on your TV screen.  See The image is too big for the TV.  Some display drivers do not like the non standard display size and you may see a message telling you that your display driver is not supported.  If so, you have the option of loading the Windows Standard Display Adapter (VGA). If you do this you will be limited to 16 colorsDO NOT MAKE ANY CHANGES TO YOUR SYSTEM UNTIL YOU WRITE DOWN THE CURRENT SETTINGS.  It is recommended that you keep your native driver and work around any sizing issues you may have - see The image is too big for the TV

 

Why do I get a software installation error telling me to change autoexec.bat?          

Part of the installation process is making an entry to your autoexec.bat file.  If this file is write protected or does not exist you will get an error message saying the system could not open the file and telling you to add the movescr.com instruction to the autoexec.bat file manually.  In most cases this is because your system does not have an autoexec.bat file.

The easiest way to create one is to open your Note Pad (or any text editor) and create a new file with nothing in it.  Save this file to your root directory autoexec.bat (c:\autoexec.bat).  Once this is done your software will install without the error message.

Do I have to change my display adapter (video card driver)?                     

NO! It is recommend that you DO NOT change your display adapter to the Standard VGA driver.  This will limit you to only a 16 color display and cause more problems for you than the sizing limitations.  This will also cause many of your programs that require higher color settings (256 or 16 Bit colors) not to run.

Why do I have to change settings in my computer?                 

The scan converter requires that these settings be made in order to produce a display on the TV. The two basic settings that you must make are the screen area (640x480) and the refresh rate, which MUST be set 60 Hertz (Hz). The refresh rate is provided by the computer (not the scan converter) and must be 60 Hz in order to get a stable display on the TV. Many video card drivers do not provide a place to set the refresh rate. In the case that you have no place to set the scan rate you must make two other settings. The first is your color – set this to 256. Secondly, set your monitor type to ‘Standard VGA 640x480’. These two settings along with the 640x480 screen size will generally get your video card to output 60 Hertz.  See General Setup and Troubleshooting for specific instructions on making these changes.

Before you make any changes to the settings in your computer write them down.

To set the 60 Hz refresh rate look for a tab in your display properties that says refresh, or the name of your video card like Diamond, Chips, etc. Look for the 60 Hz setting. If you are using Win95 OSR2 (release B), look for a drop down box on your Adapter card in Advanced properties. There may be a listing of refresh rates, choose 60 Hz, or if no listing select Adapter Default (not Optimal).

How far can I run a cable to the TV?                    

There is a practical limit of about 20 feet between the scan converter and the television. We have received reports from customers that they have achieved distances up to about 50 feet using good shielded cable using the composite output (RCA) connector. We have also had reports of up to 100 feet using expensive Monster Cable on the S-Video output.

Please note that AITech will NOT troubleshoot nor support installations with cables longer than the stated 20 feet. If you have in installation with a cable longer than 20 feet and you need technical support for you scan converter please install the requisite 20 foot cable before calling us. If you need a long run from the scan converter to the TV it is recommended that you purchase a video amplifier and use this to drive your long cable. You should be able to find one of these amplifiers at any good video supply store.

How many TV’s can I use with my scan converter?                  

The scan converter you have was designed to send a signal to a single TV but should be able to drive two TV’s without using an amplifier. You may be limited to a total of about 20 feet of cabling (to both televisions). Note that you have two outputs on your scan converter. These outputs are the composite (RCA) and the S-Video outputs. There is no reason that you cannot use both outputs at the same time. If one TV has an S-Video input use that for one TV and the composite (RCA) input for your second TV. If you need to drive many TV’s it is recommended that you purchase a video distribution amplifier for this purpose. You can get one of these from a good video supply store.

What does NTSC and PAL Mean?                    

These are the television standards used:  NTSC is used in North America and PAL is used in most of the rest of the world.  Both standards evolved before the PC and have some limitations.  NTSC uses a refresh rate of 60 Hz.  PAL has a refresh rate of 50 Hz.

What are the differences between the S-Video and Composite video outputs?            

Composite video mixes the color (chroma) and brightness (luma) information into one signal.  S-Video (separated video) separates these signals and provides the highest quality image on your TV.

How can I get the best results on a TV or video tape?            

Do not use high contrast colors, or opposite colors (red and blue) - especially next to each other as they tend to bleed.  For video tape, record a test screen. 

What can I do with a Web Cable and a VCR since my TV is plugged into one?                 

With the Web Cable you can record your favorite Web pages onto a video tape and review them as many times as you wish.  You can also record how you program a computer or how to use a specific program showing step by step how to do it as an educational video tape.  Animations, games, or video clips can be recorded so show the best actions.

Can I use the scan converter with my laptop computer?                   

Yes. There is no practical difference at all between using a desktop computer and a laptop. The main difference is in the monitor connection. Since you are using a laptop you will likely not be attaching a standard CRT monitor to the scan converter.

When I use my laptop I can only see it on the TV or the laptop but not both.                   

This is a function of the hardware design of the laptop. In most cases you will probably not be able to see both displays at the same time. The reason for this has to do with the way a TV operates and the fact that the refresh rate is dependent on the computer. When the laptop is in the simultaneous mode the computer switches the signal back and forth splitting it between the LCD display and the CRT display (where the scan converter is attached). With most laptops you must switch your laptop to the CRT or "external only" mode in order to see a stable display on your TV. You will know you are in the CRT mode when the laptop screen goes black.  The MultiPro Plus, PSC-2000 and the MultiPro 2000 use a newer technology chip.  With these newer scan converters, you can usually have your image display on the laptop screen and TV screen simultaneously.

How do I get my laptop into this CRT mode?                     

Most laptops have a hot-key combination using the Fn key (lower left corner of the keyboard) and one of the function keys at the top of the keyboard (F1 … F12). You should see an icon of a monitor on one of these keys or the lettering LCD/CRT or something similar. Hold the Fn key and press the associated F# key. This is usually a three mode switch – it rolls around between LCD, Simultaneous, and CRT modes. You will usually have to press this key combination two times to turn off the laptop screen. Please refer to your user’s manual on how to do this.  You can also go here for a listing of many laptop brands and their hot key combinations. This list does not cover every laptop nor does it specify models.

My laptop has built-in TV - is this a problem?                    

If your laptop has built in TV output it may cause a problem with your scan converter.  Be sure that this feature is turned off in your laptop. You may have to do this in your system BIOS.

Why can’t I get the scan converter to connect to my TV?                    

There are two types of connectors available with our scan converters, the composite (RCA) and the S-Video connector. In order to use the scan converter you must connect it to a matching connector on your TV or VCR.  All VCR’s have at least one set of video input connectors. This is to allow for recording from an external source, such as a camera. Most newer TV’s have these same RCA connectors for direct video input. Some TV’s and VCR’s also have S-Video inputs.  If you have S-Video inputs on your TV or VCR, use them for the sharpest possible image.

If your TV does not have an RCA connector (composite) input you will not be able to use your scan converter in its current configuration. You have two choices at this point. You can use your VCR if you have one, or purchase an RF Modulator. The RF Modulator changes the composite video signal to an RF signal. The RF Modulator attaches to the TV using the F-connector (the screw on coax connector where your antenna or cable-box cable attaches). You can purchase an RF Modulator from Radio Shack for about $30.  You cannot use a simple adapter that changes the RCA cable connector into a F-connector.

If you attach the scan converter to your VCR you will have to set the TV channel to the one used in your area for VCR’s (channel 3 or 4). You will then have to switch your VCR to its External Video Source. See next entry.

Why do I only get snow on my TV?                     

Snow on the TV screen (the random "salt & pepper" screen with the sound of rushing water (white noise)) is an indication that the TV is expecting to get input from its tuner via the antenna or cable box. In most cases you will need to manually switch your TV to its video mode. There are a few TV models that have an automatic switching mechanism. Please refer to your owner’s manual for instructions on switching your TV to its video mode. For a listing of many TV brands and their method of switching, see this.  In most all cases you will need to use the remote control that came with your TV to make this video mode change.  Many so-called "universal remotes" do not include some of the special functions like this one. See next section to set VCR to its video mode.

Why do I only get a blank blue or black screen on my TV (or connected to a VCR)?       

Your VCR (as well as some newer and more expensive TV’s) has a video blanking feature that will not allow the loud white noise and ‘snow’ to be displayed on the TV, when it does not get a normal TV signal. The above section describes the setting of a TV to its video mode. Setting the VCR is very similar and usually requires the standard remote control to switch to video mode. Like the TV, the VCR requires you to switch it to its external video mode.  Please refer to your owner’s manual for more info, or click here for a listing of many VCR brands and their method of switching.

Why don’t I hear the computer on my TV – or how do I get sound?                     

Your scan converter is a video conversion device.  It converts the computer’s VGA signal to an NTSC composite video signal (or S-Video) that can be used by your TV.  This device does not do audio.  If your application demands the use of sound at the TV, or if you are taping your presentation and desire sound on the tape, you must connect an audio cable from the LINE OUT connector on your sound card to the audio input connections on your TV or VCR. You will need a suitable stereo or mono cable and an adapter from the 3mm stereo jack in the sound card to stereo RCA jacks. Both of these items can be purchased at Radio Shack or any stereo supply store.

Do I have to attach a monitor?                     

It is not required to use the VGA pass through to use the scan converter. 

Why does the TV look fuzzy or blurry?                     

A TV does not have the capability of displaying fine text clearly on the screen.  If it did, we would all be using cheap TV's on our computers instead of expensive VGA monitors.  Some TV's are better than others, and this is not always related to the cost of the TV.  There are several controls on the TV that can enhance the image.  Adjusting color, sharpness, contrast, and brightness can help enhance the image coming from the computer. 

For giving presentations using applications like PowerPoint, playing games, showing pictures, working with graphics, or surfing the web, your scan converter should work well for you.  For applications such as word processing, database work, and other text intensive applications, you can opt for using a large text within Windows. 

There are several things you can do to enhance the fonts on your system if you use programs that have smaller fonts. 

 

Internet Explorer:

You can select a larger font for displaying the Internet pages you are showing on the TV.  Click View - Fonts - and select a larger font to your liking.  Note that Medium is the default font size for the normal screen view.

 

Windows 95/98 Desktop:

You can specify the font for different areas of Windows.  To get to your Display Properties, just right-click a blank area of your desktop screen - click Properties at the bottom of the menu - and click the Appearance tab at the top of the dialog box as shown below.

Please note the graphic above that show you how to set the font for the different areas of the Windows.  Note the Item list shown immediately above.  This list will allow you to change the appearance of virtually all areas of your desktop.  These instructions show you how to change the font size for the Desktop Icons.

 TextSize2.jpg (47592 bytes)

 

The graphic above shows you how to change the font size.  Select the size you think will work and click the Apply button.  If this setting is not suitable for your needs choose one higher or lower that you like better.  Note that the default font size is 8 point text. Standard printed text is 12 point. The list goes up to 18 point text but this setting may be too large.  Click the OK button when you find a font size that you like.

Can I use my scan converter in DOS mode?                     

The simple answer is yes.  Usually the default state of the video card is 60 Hertz in the DOS mode.  In some cases you may have to run the program on your install disk called movescr.com.  This program will stabilize your DOS refresh rate at 60 Hz.  You can add this file to your DOS (or any) folder and make an entry in your autoexec.bat file so it will run whenever you go to DOS mode.  You can also create a shortcut and run it manually whenever you need to work with your scan converter in DOS mode.

How do I use my scan converter with a PAL TV?                    

You will have to install the software if you want to use the scan converter in a PAL country or with a PAL TV or VCR.  When you install the software you will need to configure it for PAL.  Follow these directions to setup a PAL scan converter.

Why do some games and DVD's mess up the TV image?                

This is usually a refresh rate issue, where the game changes the 60 Hz refresh rate required by the television.

Some games, DVD software, (and other programs) are programmed to bypass the settings you make in Windows.  These programs are typically DOS based programs.  Windows is supposed to control your computer.  Strictly speaking, any program that does not use Windows to control the computer is a non-standard program that is NOT Windows compatible.  Games are notorious for controlling the display directly instead of going through Windows.  Once the Windows settings that you made have been bypassed (and the refresh rate changed), there is nothing that you can do to bring your scan rate back to 60 Hz.  You must be able to do this from within the game program.  Sometimes changing the colors and/or screen size can bring the image back to your TV.  If you want to play a lot of games on your TV, it is recommended that you look into our MultiPro Plus, PSC-2000, and MultiPro 2000 scan converters, which in most cases should allow you to play all of your games and DVD's without a problem.
