PC to TV EZ (model# GEZ-1000) - Trouble Shooting

If you are seeing COLOR BARS, then your computer's settings need to be adjusted.

What to do on your computer...

  1. Go to the Start Menu -> Settings -> Control Panel
  2. Click on the "Display" icon
  3. Click on the "Settings" tab
  4. On this tab, there is a section called "Screen Resolution". The resolutions are labeled by HORIZONTAL PIXELS x VERTICAL PIXELS. (example: 1024 x 768)

FAQ

Q: How can I enhance the display quality?
A: You can usually decrease the TV contrast and increase the brightness control to get a better picture.

Q: I have an older model of a television. Would I be able to use my video converter with an older television?
A: Yes, you may need a VCR or special adapter called an RF modulator. This device converts the composite video signal from your video converter to an Antenna signal, which can be viewed on your TV using Channel 3, 4, or 13.

Question: How do I use my VCR as an RF modulator?
Answer:

  1. Install and interconnect the "PC to Video EZ" normally, but connect the composite-video cable to the VCR's "Video In" jack instead of to the TV.
  2. Turn on the VCR and the TV. Switch the TV to the channel that receives VCR inputs. Play a tape for a moment on the VCR to make sure you can see the program on the TV screen, then remove the tape.
  3. Consult your VCR manual to find out how to set the "input source" mode for the VCR. (Generally, they have two or three input sources: 1. "TV, Cable, and Tuner"; 2. "Video In"/"Aux"; and sometimes one called "Tape".) Set the input source to "Video In"/"Aux". Your TV should now display the images from your "PC to Video EZ".

Question: Can I use multiple televisions to view the same image from my computer?
A: Yes, "PC to Video EZ" provides 1 CVBS OUT and 1 S-VHS OUT.
You may connect one television to the next using a composite video cable or an S-Video between the "Video-In" and "Video-Out" ports.
We recommend using no more than five or six televisions.

FAQ

Q: Why am I getting a test pattern on my TV and no picture?
A: 1. The VGA cable connected between the VGA port on the computer and the VGA In/Out on the Internal Card is backwards. The end of the cable with the VGA connection should be connected to the "PC to Video Component".
2. Make sure the POWER and CHANNEL settings of your TV are correct. If the TV has a remote control, make sure it is not being triggered accidentally. 
3. Make sure that the correct type of input (VIDEO or S-VIDEO) is selected on your TV. If possible, connect a VCR, camcorder or other output device to the TV's video input and make sure that the TV is accepting input through the selected connector.

Q: When I connect my TV to the GrandTec product through a VCR, I get no picture on the TV... what do I do?
A: 1. Make sure your VCR is outputting on the channel that your TV can receive auxiliary input on. Consult your VCR manual if necessary. 
2. Make sure that the VCR is set to receive input from the VIDEO IN or AUX.

Q: I have DTV, EDTV, or HDTV. Can I use the Y.Cb.Cr output to get a digital display optimized for my digital TV?
A: No. They Y.Cb.Cr output is converting the analog progressive VGA signal into an analog interlaced signal for display on the TV. The Y.Cb.Cr output offers the best clarity for scan conversion, but it is not an analog to digital conversion.

Q: Why is the TV not displaying portions of the display when converted?
A: Your display might be running in OVERSCAN mode (placing portions of the picture beyond the boundaries of the screen's visible area). This typically occurs because VGA graphics have more display lines than the TV can handle. Togge through the H-SIZE and V-SIZE settings in the MENU until you find the optimal setting for your application.
Note: The SIZE control allows the entire image to be displayed by reducing it and putting a crisp, black border around it. Use this control in situations where edges of the image would otherwise be lost due to overscanning.

Q: There are "noise lines" on the TV picture.  How do I get rid of them?
A: There are four settings in most televisions that affect the clarity of the display. The same adjustments can be used to improve the clarity of the display whether you use a converter or not. 
The settings are:
1. BRIGHTNESS: Typically, the brightness setting is by default too high. A high brightness setting often causes the display to flicker. 2. SHARPNESS: If the sharpness is set too high, often the result is what is termed "dot-crawl", where edges of the image appear to move. Lower the sharpness to soften the edges. 3. COLOR: If the color is set too high, often the result is colors that bleed or appear to sparkle. The high (purple) and low (red) frequency colors are most affected. Adjust the color setting down to soften the colors. 4. CONTRAST: If the contrast is set too high, often the result is exaggerated colors. Adjust the contrast down to complement the SHARPNESS setting

IMPORTANT NOTE - connecting anything other than the 6v DC power supply with a center positive connector to the Ultimate Wireless will cause damage to the product and will void the warranty.

Receiver Configuration
 

STEP 6: Connect the Ultimate Wireless Receiver to your TV using the A/V Cable.

Make sure that the yellow goes into the yellow jack, the Red goes into the Red, and the White goes into the White.

The picture on the right shows the A/V Cable hookups going into a TV's "Video-In" (for the yellow video cable) and a TV's "Audio-In" (for the red and white audio cables)

Don't forget to plug in the DC power into the Receiver unit, just as you did with the Transmitter in Step 4.

STEP 7: Make sure the receiver, transmitter, PC, and TV are all turned on.

Make sure your TV/VCR/DVD/Projector is turned to the right input channel. Depending on your TV, it may be label differently.

(It may be labeled "Auxiliary" or "Composite" or "Video Input 1/2/3/4/5/6etc")

When the correct input is selected an image shows up on your screen.

Transmitter Channels

If you are experiencing any distortion or interference in the wireless transmission, change the transmission channels.
Using a paperclip, change the switches on both the transmitter and the receiver so that they are on the same channel number.

Only one switch should be down on each and the switch that is down indicates which channel is in use.



In this example, Channel 1 is selected on the Transmitter.
(The transmitter DIP switches number 5 and 6 should be in the off or up position.)

 

Other Things To Check

1. The input on the display (TV, projector, etc.) is not properly set. If your display has multiple video inputs, then you have to toggle the inputs to display the one you need. Typically this is done via the remote.

2. The TV looks fine during boot-up but once the PC enters Windows, all I see is black and white horizontal wavy lines: The display adapter (video card) is set to a refresh rate not supported by the converter.

  • Go to StartMenu -> Settings-> ControlPanel
  • Click on the icon "Display"
  • Click on the "Settings" tab.
  • Click on the button "Advanced".
  • Click on the "Adapter" tab.
  • Change the Refresh Rate from Optimal to Adapter Default or 60Hz and click apply.

FAQ

Q: How can I enhance the display quality?
A: You can usually decrease the contrast and increase the brightness control to get the better picture.

Q: I connect using a Notebook, but no output is displayed on the TV. What do I do?
A: To get a converted image on the TV, you must configure the laptop computer to display an external VGA signal. Typically this is done by toggling the "FN" key + "F1", "F2", etc. The actual function keys vary by computer.

Q: I have an older model of a television. Would I be able to use my video converter with a television as old as this one?
A: Yes. You may need a special adapter called an RF modulator or a VCR. This device converts the composite video signal from your video converter to an Antenna signal, which can be viewed using Channel 3, 4, or 13.

Q: Can I use multiple televisions to view the same image from my computer?
A: Yes, Grand Ultimate Wireless provides 1 CVBS out, 1 S-Video out, and 1 RGB out. You may connect one television to the next using a composite video cable or an S-video cable between the "Video In" and "Video Out" ports. We recommend using no more than five or six televisions.
