Is composite video good enough for passengers?

**DarrylR** · 03-13-2004, 04:04 PM

I read a very informative post entitled "VGA vs Composite" by CProaudio in the Newbie FAQ, but after reading it, I'm thoroughly confused about my rear seat monitor choices.

When I began planning this project, I assumed I'd use a head unit with a built-in LCD. However, CProaudio's post suggests that VGA is the only way to go if you want to be able to actually read the screen. I know that shell programs such as MediaEngine and MediaCar can help improve legibility for controlling my car pc, so I assume that I could use one of these programs instead of investing in a VGA monitor for the front seat (although I see the value of a Xenarc VGA touchscreen too).

But where does this leave passengers? In order to keep this project within budget, I really wanted to install TFT LCDs with composite video input in the headrests (for passengers to watch MPEG video and/or DVDs served by the car pc). Is the quality of composite video so bad that they wouldn't be able to enjoy a video?

Thanks in advance,
Darryl R.

No, video doesn't look to bad.

I run media engine on a composite screen and it looks perfect...I'll try to find some pictures. The only things you have trouble seeing are the settings menu's, and you never have to adjust them once you get it configured, and I just attached a CRT monitor to do those.

Same as telekinetic.

Using a 5.6" composite LCD with ME and a numeric keypad for control.

Thanks for the info, eCar, telekineticfool, and kami333. I've downloaded Media Engine and Media Car. Now all I need is a VGA to composite adapter to test the prototype using my laptop. The adapter will also be used if I go with a non-mini-ITX (read P4) solution that doesn't output composite video. Any recommendations?
