Need Help for 1303 - Pixel Qi 10" LCD 1024x600 - VGA Port

Post by HacknSolder »

WHAT I PURCHASED

I have the Pixel Qi LCD: https://www.adafruit.com/product/1303
It came with a RTD2660H display board: https://learn.adafruit.com/hdmi-ubergui ... iver-board

WHERE I'M USING THE LCD

My first computer is a Dell XPS m1710 gaming laptop running Windows XP 32-bit. On the back you'll find a DVI port and a VGA port (a 32" LCD screen is using the DVI port). Here's a image http://i.imgur.com/DA9Z5IH.png The second is a newer, self-built computer running Windows 7 64-bit. I have a nVidia GeForce GTX 650 with 2 DVI ports. My motherboard has 1 VGA port.

THE STEPS I TOOK
  1. I plugged the power cable into the controller board's power supply. (Worth noting after plugging in the power for a second the light on the keyboard controller changes from green to red and stays red until I unplug the power cable. I don't know if red means good.)
  2. Using the keyboard controller I turned on the LCD and then changed the input to VGA.
  3. I then connected the Pixel Qi LCD to the VGA ports on both systems.
  4. The LCD does not appear in Screen Resolution (Windows 7) or Display Properties (Windows XP) as a "third" available display option.
  5. The only thing I see is a blue screen with the words "No signal".
On page 6 of the HDMI Uberguide it states, "All our screens have been tested with a Windows desktop computer (we run Win7 but it should not matter which version). You can also use these displays with a Mac and even a console like an XBox (you'll want the higher resolution displays for this, 1280x800 is best)."

IN SUMMARY

I tried connecting the Pixel Qi LCD into the VGA ports of a computer running Windows XP 32-bit and another computer running Windows 7 64-bit and neither worked.

QUESTIONS & GUIDANCE

What am I missing?
Do I need to so something more than what I am doing?
Does the VGA port on the controller board require something else I don't have? I bought https://www.adafruit.com/product/1303 so I figured it was a kit.
Do I need to install drivers?

Please help. I don't know what the next step is.

The power supply that comes with https://www.adafruit.com/product/1303

I have more information to share. I have a HDMI-DVI Radio Shack cable. On a whim I tried using this on the Laptop. It worked! So I can confirm that the HDMI port on the controller board works. I have reason to believe the either the VGA cable I'm using isn't working (basically it's a DVI cable with DVI-VGA adapters on each end) or the VGA port on the controller board is defective. It's also possible the VGA port on the laptop isn't working. After work today I will buy and test with a standard VGA cable and post my results.
