Fair enough and good information to know. Now it just a long wait for delivery!  Wink

Been a while since posting.  I should follow up on my previous post by saying, yes, the controller worked with that screen.  I've moved on from there into a different project.

I picked up the NJYtouch programmer and have been using it to experiment.  I now have two NJYtouch 5451 DVI LCD Controller boards, and two Toshiba Tecra M4 tablet PC monitors, (14.1" 1400x1050, 4:3), and I was successful in getting them to work.  -That combined with the Waxbee project, (which allows the Wacom Penabled digitizer built into the LCD screen to work as well), has resulted in two perfectly serviceable Cintiq-like screens which can be plugged into any computer.  The total cost for one working screen, assuming around $50 for a Tecra M4 screen on eBay, is. . .

$50  Tecra M4 screen
$30  Penabled Stylus
$35  NJYtouch controller
$20  Teensy 2 with voltage regulator
$40  Shipping
-------------------------------
$175

That's not too shabby!


Anyway, as many of you may already be aware, the NJYtouch programmer doesn't let you input specific driver parameters.  Instead, it only allows you to pick from a pre-established list of existing screen drivers.  There are lots of them covering a wide range of screen formats and manufacturers, but the Toshiba 14" wasn't one of them.  So I ordered the programmer on blind faith and hope.  I am happy to report that it paid off in spades!

FIVE of the nine available driver specs worked.

They are:

HSD150P1C17_DO6L_1400_1050  (This is the first one I tried.  Looks great!)
LP141E2_B1_DO6L_1400_1050
LP141E04_DO6L_1400_1050
LP150E06_DO6L_1400_1050
LQ141F1LH02B_D06L_1400_1050    (This one seemed to look slightly better on SVGA compared to the others.  That may be subjective on my part, though.)

Evidently, at least in my case, LCD screens are not always too dissimilar across manufacturers.  Any of the above specs will drive a Tecra M4 screen on the NJYtouch controller board.

Perhaps this information can be added to the Waxbee project FAQ page.
