LCD panels

[HanClinto]

Yeah, I saw those 2" LCD's on E-Bay advertised as a Spy Monitor or something like that... search for Spy (LCD, TFT) and you'll find some dude from Hong Kong selling them for $60 or so, with $20 shipping to the states. I think it worked out to $84 for me to get one to my doorstep, but the resolution was a little too low for me... something like 120x240 or 360x240 or something... I don't remember what it was.

Like you guys say, a separate thread would probably be best.
Interest will build up as LCD monitors keep getting cheaper. I would suggest a separate thread. It will be some little time before people get confidence and technical ability to do the modification, and you may even find LCD monitors that don't need modified, it and every scrap of information will be very helpful. Even if you just take a monitor apart and post some photos for other guys to look at and offer helpful suggestions.

So far in this whole Video section there have been two failures.
There may have been other successes but not posted.
JJasniew and Maddog_rvo
And two successes
Myren and Yander26

Heres a couple of points to consider.
A 15 inch is just too big to fit on an OHP.
A 14 inch will just fit see Yander26's post page 8

A guy in Video projector part 1 (Myren) found a Viewsonic that only had 1 inch wide boards. He did not need to move the boards, only a small controller board and that without lengthening any wires.
I will find the exact post if you like.

Go for it Rekr. Open one up.
How about
"What types of LCD monitors are good for projection"
"How can we modify LCD monitor for projection"
"What are the easiest LCD monitor for projection"
"Good LCD monitor/Bad LCD monitor"

A regular VGA card.

I thought you might have to use something like that.

So option 1 does need a computer or a controller board of some description. Just exactly like I said.
Some people might not like to tie up a dedicated computer to drive their projection panel and opt for a controller instead.

Option 2 does not neccesarily need a controller board. It could be driven from a computer. Just exactly like I said.

OK I started the new thread, hopefully will start to see some interesting results in the near future, as soon as I found an LCD montior for around 150 I'm gonna experiment. I might have to take a ride into Canal Street this weekend and do some haggling, week before Christmas I might be able to get somone to drop below the 200 dollar mark, wish me luck.

Good luck

I'm not trying to argue (seriously) but you asked what you'd drive a desktop LCD with and I answered. So option 1, you need to dedicate a computer and a standard VGA card (obviously). Option 2 you don't neccesarily need a controller board? I'm confused. Are you saying someone who could learn all the hardcore technical knowlede about LCD's could get one to work without a controller board? Because you didn't mention the "no controller required" part in the original message. Do you really think that's possible, or am I completely not understanding what your trying to say?

My original point- while both options obviously require a dedicated computer, option 1 only requires a reg. VGA card because the controller comes built into the desktop LCD (which you obviously already know). Option 2 requires a special controller (unless I missed something) that performs one or more of the following tasks:

AnalogRGB--->TTL, AnalogRGB--->LVDS, DVI-->TTL, DVI-->LVDS.

The cost of that controller is significantly more than a regular VGA card, which is why option 1 may be better, depending on the price.

I think the best idea is just to ignore Lifter and he might go away.

I have found the ignore button in Lifters profile and he is now the one and only person I ignore. Ain't life grand.

Hi guys.

Without picking any sides in this little argument that is going on between some members of the forum, I must say that people are getting a bit to upset at each other a bit to fast.

I found remps comments very valuable but then I could not easily understand the differences between option 1 and 2. Lifters comment and remps additional response cleared my confusion.

Having said that, I don't think its worth arguing about every little detail in our posts. I think its great that people in this forum are all working towards the same goal of building a cheap and great quality projection system. Everybody's contribution helps.

Lets forget about what has been said and lets just continue the great work.

Cheers,

Exipnos.

i got this reply from those guys giving me a quote :
<<<<<Hi Jean- Pierre Scherer,
The following price is for your information:
LD-S270 USD120/pc
V-cable-33160 USD15/pc
Quoted price is based on FOB Taiwan.
Please let me know if you need a Proforma Invoice.
Look forward to hearing from you soon.
Best Regards,
Susan>>>>>

both panels can be driven with the same LD-S270

so if i get myself one of those boards( i supose they are pci)
everything should be ok right?

who thinks so too?
