Post by: kickstart on November 04, 2010, 02:19:17 AM
Hi.

Watching demos like the music disk music dream 1 and 2 the main scroll isnt smooth at can be.

Thanks.

I noticed this more with Invision ECS than the AGA one.  Which one are you using?

Have you considered the fact that the scrolling may be strictly intended for 50Hz refresh and you're watching the output on a display using a different refresh rate?

Get a monitor that can sync to 50Hz and configure the Indivision to output at 50Hz.

Valmis!

Perhaps you can get away with NTSC which runs at 60Hz and is possibly a better fit for modern LCDs.

Its a pitty, im googling about the frequencies supported by my monitor.

Force the demo to run at 60Hz (Use WHDLoad?) and the scrolling will be smooth. (albeit a tiny bit faster)

FWIW most Eizo LCDs sync down to 50Hz using the VGA input. I've had mixed luck with other brands.

Yes, all demos and games are loading by whdload but is new to me the the 60hz option, thanks.

@all

My monitor is a lg l1952s 4:3 the limit on this monitor is 56hz but im not sure.

It reminds me of something...

I used to own a Minimig but sold it back because my monitor wouldn't accept its 50 Hz output (and I wasn't satisfied by the 60 Hz mode). What puzzled me is the fact it did accept a 50 Hz output from my "internet provider TV Box" (how do you call that in English ?).

There are probably tons of differences between those 2 devices... Different resolution but also the fact that the former was using a VGA plug and the latter an HDMI one.

Any idea ?

HDMI is used to connect video devices so it's more probably accepting  50 hz/15 kHz signal. VGA devices tend to default more to 60Hz/31 kHz so it may make a difference.

jens announced a new indivision1200. it will have dvi and use ddr ram on it. hopefully this will be a better product...

do you use the x1.25 or x1.0 setting in indivision config?

New indivisions are cool for sure, but frequencies are still frequencies.

I had to change a jumper on my Minimig before my Samsung LCD would work properly with it, don't remember the specifics.

100Hz capable monitor will do too, as it just doubles the refresh rate and keeps the Hz ratio. IIRC that is.

The default configuration for scanmode is x1.25, which will display NTSC modes
at 75hz & PAL modes at 62.5hz resulting in not perfect 50hz scrolling. Using x1.0 is the best solution, but some screens cannot cope with 50hz signals.
