Leslie,
You're right that looks real bad. OK here are a couple of "dumb" questions. Please remember I'm no expert at LCDs.

Have you done a pin check on your cable and confirmed that every connection has low resistance and that there are no shorts? What I did was do a pin to pin check from connector to connector on my homemade cable, then I did a pin to every other pin check to make sure there were no shorts.

Does your windows screen look ok? Mine does and so does WinAmp.

Have you tried the GPS SW on a regular monitor at 256 to see what it looks like?

have you tried the GPS sw on a Laptop at 256 colors?

Have you tried using 16 bit color? (I'm sure you have but I just have to ask)

Here's why:
256 colors = 256 colors Duh

Alot of stuff looks pretty bad with only 256 colors including winamp.

12 bit = ~4000 colors

16 bit = ~256,000 colors

On the pic I can see red, blue, and green so i have to presume you are getting all the colors. The problem might be you're not getting all the LSBs which is wreaking havoc on your screen pic. maybe at 16 bits you'll get all 4000 colors and it will look better.

Note that the 12 bit screens really don't look that good for DVDs/movie playback but my screen looks good with Windows, Winamp, Sonique, etc. and looks OK for some games (MTM II and kids educational games). I don't have GPS SW so i can't comment on that.

Hope that helps.

Im starting to think that my problem is the hirose connections. I looked at the tft controller pinout and it seems like my HSync isn't even hooked up. I'm starting to think that my thing is completly wired wrong. Even at boot DOS looks bad, the letters are white and have red around them sometimes. Could it also be that I'm using a 25 foot VGA cable? I donno. I can't really test it any other way. I have to play around with the settings so much to make it look good so I'm thinking that the screen is wired wrong.

LESLIEx317537 · 03-22-2002, 11:11 AM

And this is my other question, if I start rewireing it, can I damage my LCD? Rewireing the hirose connections. Like if I put HSync on R3 by accident???

Hi Leslie,
Yes you could damage your LCD or just as bad, your controller.

I already blew out an allen controller hooking up my custom LQ9D161 cable backwards. What a shame.

At least the LCD was still OK.

Your 25 foot cable is not helping but it is probably not the root cause of your problem. But if you can get shorter one it is definitely worth a try.

How do you know the cable you have is wired correctly?

More questions:

Exactly what LCD do you have?
Exactly what controller do you have?
What cable do you have and how is it wired?
Have you confirmed your cable is wired properly with a VOM?
Have yout tested the 25 foot VGA cable to confirm it works with a regular monitor?
Is the PC you're using to test it OK?
Can you test your current set up on another PC or with a different videocard?

Did you try to put the sitting on 16bit ?? .. try that it might help ..

Look at how we connect the tft controller to the LCD .. on the 2nd post from "pigseye" show all the connections to allen's tft controller and LCD. Trace all the wiring one at a time to see if they are wired right for your controller.. (I remember seeing a link to a .pdf for your TFT controller on Dennisk's auction)

I am going to trace the pin outs.
I got the tft controller manual and lcd pdf.

I tried 16 bits and it looked even worse. I left it on 8 bits.

I played 8bit on my reg. monitor and it didn't look as bad as what my LCD is showing. Sometimes colors that blend sparkle. It's weird. And the DVD's have greenish glowing skintones and lights look that way too.

When i played 8bit mode on my reg. monitor DVD's even looked fine.

Hi Leslie,
I noticed that too when playing dvds on a monitor. It seems like it doesn't matter what color setting you set the display at on a monitor for dvds. Sure makes a huge difference for CLDs though.

I'm a little surprised that at 16 bit it got worse. That leads me to believe there is something wrong with your cable.

Keep trying.

Update: Perfect picture,I'm so happy.

Rehooked up birose connections to proper color thingies.

On my 8bit controller that DennisK got me.

I did:

Panel Controller
R3 to R7
R2 to R6
R1 to R5
R0 to R4

etc....
