Problem with 100Hz TV and Dreamcast

Estevez · #1 16-03-2003, 00:21

Hey guyz. Have bought recently new 100Hz TV and it appears, that approx. 60% of my games have "shaking/jumping" screen (like wrong frequency).
The Dreamcast is European, the TV has the NTSC through the SCART only. You have any idea what shall I do with it ?
Thanks for any suggestion.

P.S. Guy from TV store told me, that same problem but with Playstation can be fixed by simply changing/adding one cable inside the console. But another guy told me, it can not be fixed as NTSC games are at 60Hz and on 100Hz TV there is no way to play it (as when doubled it would have to be the 120Hz TV).

Well i got a few friends who has a philips 100hz widescreen TV since a year of 2/3 and played DC fine on it, both 50 and 60hz games. But lately another guy who lives next to me also bought a DC and tried to play on his JVC 100hz widescreen.. he had massive slowdown in crazy taxi and weird textures in capcom vs snk. They all used rgb scart.

I have a Panasonic Quintrix 16:9 TV and 2 DCs, one PAL one JAP.
No problem at all with/without RGB cable, at 50/100 Hz on TV and 50/60 Hz from DC.
The only real problem I have is the Madcatz Gun, which seems unable to calibrate.

Tx guyz. OK I have checked it carefully and the problem appears when game runs at 60Hz (so it is almost 90% of games). Do you think that the reason of that may be the connection cable as I am using the regular antenna connection ? Maybe switching to RGB cable will fix it (as when chosing the RGB source in TV there appears the option of switching to NTSC and some other systems, except PAL/SECAM) ? I need to buy such cable anyway.
Tx & keep kewl ;-)

Yes, that's a chance. My TV for instance has 4 SCARTs and 1 RF antenna plug. Every plug has different signal support.
That means that if I want to use RGB cable I must use 1 particular plug, not the others, otherwise I have sync problems.
You definitely want to buy an RGB cable

Yeah, mine has 3 SCART and 3 others. Im already placing an order for that RGB cable. If this will not work, will have to use this Megalex Pal Patcher that I have just fund on the forum here, at least for some of my favorite games (like UFC hehe).

UFC works without any patching. For RGB you only need Pal-patcher mainly for JAP protected games. USA games don't need it on PAL DC.
For 50/60 Hz, yes, it is useful
