Need HELP working my 5" LCD

Gold_Cat · 09-20-2002, 04:42 PM

I have a Pyle 5" LCD and a ATi 7500 video card. When I first hooked the LCD screens RCA video cable to the video card I got no picture at all. Then I looped a VCR in (hooked the RCA cables from the input of the VCR to the video card and hooked the LCD rca cable to the output of the VCR) and when I turned on the CPU I still got no picture but I changed the channel on the VCR and I finally got a picture. Someone told me this was because the signal needed to be modulated. I now want to get rid of the VCR all together but I don't know what to use to modulate the signal. I want something as small as possible. Any help would be appreicated!

This may work.

1. First hook up the computer to a standard VGA monitor.
2. Make sure you have the most up to date video drivers from ATI
3. In your display properties there is probably a monitor selection mode (change it to either TV or if you can both).

Let me know if it works.

Buy/make a 75 Ohm RCA cable.

BTW: USE THE SEARCH

I know this thread ended quite some time ago (but i used the search!)

I am encountering a similar problem, the tv button is greyed out and it cannot detect my lcd, i am using a 75 ohm video cable and its not finding it! PLEASE HELP

ps - i am using a ati all in wonder 128

UPDATE

Well, I hooked it to my tv, activated it under the menu and then switched the cable, it worked! Then I disabled my monitor and used just my lcd, was stoked that it was working. Then on reboot, everything went back to normal since it couldn't detect the lcd again

suggestions?! It seems it has to detect it, which I don't understand why it isn't!

Does the LCD have power then you try and detect it?

It might not be able to detect it when its turned off.

Just make sure the lcd is connected to your computers power supply, so it comes on at the same time.

this set up is still in my room until i perfect it (getting so close!) the lcd has full power before, during and after the computer is powered on

Solution to problem:

Albeit a costly one

I purchased a video distributer from radio shack, essentially a video amplifier. Thats all it needed. It was WAAY OVERBOARD for what i needed, especially since it was a 4-way distributer. but for $40, it fricken works. I'll return it if i come across a better solution! But finally! So although i was still using 75 ohm cable / resistors the lcd was still considered passive and the video signal needed to be amplified. So for the tv-out to detect it I tricked it into thinking the distributer was the "tv". Problem solved! Now if I could just get the mind factory to send my USB Fm Modulator, i'll be all done!!!!

I was in a similar situation some years ago with a Viper card.
The 'Tv out' option was greyed out. It had to have the cable it came with plugged in!
