I have just purchased a TFT monitor without a power cord. It is rated for 12V and 3 AMP. I have a wall-to car adapter that outputs 12V and 3.5 amp. I plan to install a cable between that and the monitor. Will the difference damage the monitor?

Joe U has the right idea - a device will draw the amount of current it needs, noi more.
Just be sure that the 12v is CLEAN - little or no ripple.

My dad installed an adapter that was rated for higher than the device he was trying to run (battery recharger) it was only $20 so when it caught fire he just said oops and laughed. Can you just go oops and laugh of your monitor is toasted? If so then try it cause I think you are actually safe up to about 5 amps - if not go to radioshack and spend $20 on an adapter that can be adjusted for voltage and amperage

That should be fine. The monitor will draw only the amount of current that it needs from a constant voltage source. Be careful about the polarity as backwards hookup can severly damage the monitor and watch to be sure of correct voltage.

The device will only consume 3A no matter how many Amps are available. Just don't forget and try hooking up TWO monitors because then the devices will be trying to draw the maximum amperage (up to 6AMPS) and that will be a firehazard.

I agree with Runescape, Do not Try it. Not unless you want toasted TFT. It is one thing to fry a cheap Memory SIMM with a Voltage change, but an amperage change like that? Wow...

No as long as the supply (adapter) is higher than the load
In your case you are ok
