Title: DCE ScanMagic & LCD's
Post by: dougal on November 07, 2009, 10:08:44 PM: I have managed to get CRT's to work perfectly using the DCE ScanMagic , but the 2 LCD's i tried did not work .

Is there any way of getting LCD's to work with it ?

CRT is no problem ... i have a 17" and it gives a lovely display using the scanmagic . But i want LCD

Actually it changes from 15 kHz to 30 kHz.

Post by: Everblue on November 07, 2009, 10:45:40 PM: Yup... you are right. Still a monitor needs to accept a sync of 50hz or less.

Post by: zipper on November 08, 2009, 09:07:57 AM: My BenQ starts from 27 kHz, 44 Hz. Some BenQs do even 15 kHz.

Switch your Amiga to NTSC mode... then it'll work with LCD's.

Title: Re: DCE ScanMagic & LCD's
Post by: Everblue on November 08, 2009, 11:42:00 AM: If you force Indivision to output at 60hz... and you play a PAL game, what happens to scrolling?
Title: Re: DCE ScanMagic & LCD's
Post by: amigakit on November 08, 2009, 11:51:30 AM: It does not alter the game rate of play as it is independent.

You have to actually see the screen to switch it to NTSC mode :(

Unfortunatly its out of stock it seems

Post by: tone007 on November 08, 2009, 12:57:25 PM: You don't necessarily need to be able to see the screen to switch to NTSC mode.

If you've got KS3.1, power up your system while holding down the two mouse buttons, wait a bit for the early startup menu to be displayed (you won't see it obviously,) and then press the space bar. That should put the early startup menu into NTSC mode. At that point you can tell the system to boot in NTSC mode.

Not really a fun workaround to do often, but it should work.

Post by: Everblue on November 08, 2009, 02:35:28 PM: I dont think that will work for games though...
Title: Re: DCE ScanMagic & LCD's
Post by: tone007 on November 08, 2009, 02:53:32 PM: Games that require (or switch to) PAL mode, no. Plenty of games can run in NTSC though, but of course there will be a fair amount that won't.
