HSync Scrolling and LCD Screens Workarounds?
« on: 11:09, 15 July 17 »
Hi,


Since CRTs are a dying breed, I was wondering if there's some kind of (hardware) workaround to display smooth scrolling on LCDs
Anybody knows if devices like the FrameMeister or a cheaper alternative would help with this?


Thanks

The framemeister would probably be the best device for that yeah,
because you can integer scale the screen (resulting in no shimmering effect) and crop the overscan.

But i could be wrong

Alternatively, you can use the OSSC, which a bit more cheaper than the framemeister.

That doesn't solve the horizontal scrolling issue, that only really works on CRTs.


I guess you'd need some external hardware though, that could emulate that behaviour and understand the timing trick that the CPC does for its smoother horizontal scrolling.

Thanks guys, good info.


At some point I'll get myself a framemeister or an OSSC and give it a go.


Cheers

I checked the following thread and bought a Sony DSC 1024G
[/size]It has a button for sharpness, if you uncheck it the scrolling is smooth.
