General scan doubler question.

[Bonami]

Hi,
I recently got myself a used A4000, shipped all the way from UK to where i am - the tropical fareast. (Thank God the 1.7gb harddisk survived the long distance!)

To my delight the 15 year-old machine came with an internal DCE SD/FF, which i plug to a Samsung 940B (http://www.overclockersonline.net/index.php?page=articles&num=311&pnum=2)

Well, with just the plain vanilla OS3.0 installed, there's nothing to shout about the display. But the fact's it works - except some demo which showed garbled moving images (probably those demos meant for OCS or ECS?).

So, my question is, why my A4000 with DCE sd/ff works OK with my Samsung 940B which, as the specs go, has 56-75hz vertical freq?

Does the DCE output strictly 50hz of vertical freq? Is the spec info (as link above) incorrect?

Btw, i take this opportunity to put out a question, can i use multiscan/ productivity mode with the DCE sd/ff? I tried but failed, but i was not sure what was wrong... (the A4000 has ROM v3.0 & WB3.0)

Kindly share with your knowledge & experience. Thanks.
Regards, Bonami.

@ Countzero,
Thanks for the info in your reply.
If i want to use multiscan or productivity mode in my A4000 already equipped w/ DCE sd/ff, do i use the VGA adapter that plugs to the original video port? ie i have to switch between two display/ monitors?

@ rkauer
Thanks. When you say "yes it will work" do you mean that scandoubler can output the multiscan/ productivity mode? If so, could you kindly share how?
(i tried by moving the multiscan, productivity, & VGAonly to the device drawer, and change the screenmode via Prefs, but the display blank out, or the system hung, sorry i can't remember exactly)

Thanks & cheers!
