The oldest LCD screen i have is about 6 or 7 years old... it will not work in 50hz mode and how can i add a custom refesh rate?

Use Powerstrip.

Also nVidia cards let you add a custom rate in the Windows driver software (nVidia control panel). But it's pointless if your display isn't capable.

I cannot find any options to add a custom refresh rate for my ATI or Intel graphics... I will give powerstrip a go with my XP machine (i won't bother trying it with Windows 7).

Thanks for the help

Just one more thing... I can run other emulators in PAL mode with Vsync enabled + fullscreen and they work perfectly (with correct audio) although the monitor tells me it's running at 60hz NN or 60hz PP (not sure what NN or PP mean ).

If it can be done with other emulators (Kega, Zsnes, Gens etc...) then is it possible for Winuae to run PAL software at the correct speed with correct audio although the monitor is set at 60hz just like these other emulators??

Eh? Whats the point of vsync without matching refresh rates? No more smooth scrolling which is the (only) point of vsync...

If you run other emulators like Kega Fusion in 60Hz (PAL Games+Vsync) it runs to fast too, music is also played a bit faster. Only the NTSC games runs perfectly smooth in Vsync 60Hz/60fps.

I have just noticed with these other emulators that the screen scrolling "stutters" slightly when running PAL games with a 60hz refresh rate... but the audio remains at the correct speed for a PAL game and crystal clear! But it's the opposite with Winuae... the audio has problems when the monitor is running at 60hz with Vsync on (the scrolling seems fine).

Then use 100Hz/Vsync in other emulators for PAL games. The refresh rate doubling gives you a smooth scrolling. WinUAE does it too, at least for CRTs. I don't have a LCD with 100Hz mode to test it.

When i use 100hz mode in Winuae the sound craps out displaying a yellow led and -99

Vsync = smooth scrolling, audio gets syncronized to refresh rate -> if you don't want smooth scrolling -> disable vsync. Simple

True, but i guess PowerPie has other problems on his PC side. Disable the hw filters and use the ddraw Line Mode double. Still audio issues?

I would prefer smooth scrolling + syncronized audio + video filters.... It works apart from the audio side of things. If i disable Vsync then the audio works fine but then i notice screen tearing

So the problem is i set Winuae to PAL 50hz but the monitor itself is displaying 60hz... So will the audio be syncronized with the monitor refresh rate or what it's set to in Winuae?

The audio issue remains with or without video filters. It's a Vsync problem as the audio quality goes bad whenever Vsync is enabled in fullscreen. It does not matter which filter or resolution i use

There is no vsync problem. Audio is always synced to display in Amiga hardware.

Either your display/driver/hardware supports selected refresh rate and you get smooth scrolling and working sound or you get some other rate than you asked = bad sound.

Nothing to do with WinUAE.

PAL Vsync is difficult with LCD displays (<56Hz is rare, _real_ >=100Hz is practically non-existing)

I think i might borrow the 17" CRT from my old 486 and try it with my old Win XP machine

Do you think there will ever be a work around for people running Winuae + Vsync with LCD screens that don't support 50hz? (apart from using NTSC mode which is a bit too fast).

There are no workarounds without losing smooth scrolling, PAL vsync requires multiple of 50Hz refresh rate. I guess sooner or later there will be true 100Hz panels

Yeah i tried Winuae's 100hz PAL mode with my 22" Samsung LCD but in reality it was only running at 85hz (the audio was even worse and the sound indicator turned yellow @ -99 ) Anyway i'm now using an old 17" CRT with my Win XP machine and it's all perfect at 50hz but it's a different story with my newer systems.

I guess all LCD users will have to wait for a decent 100hz screen to arrive so that we can run Winuae properly with Vsync (Good thing i still have a couple of real Amiga's left )

If you're running WinUAE with a sample rate that your sound card does not natively support, sound's going to be resampled, and that usually creates some kind of distortion, specially with vsync on because you're putting extra strain on the CPU.

Here I get crackling at 32000hz (not that I ever use it) no matter what. At, say, 48khz, it's all smooth, no crackling whatsoever, but I definitely notice how sound becomes "wobbly" with the lowest buffer size, but that's of course, the hardware being pushed to it's limits, no reason to pass the blame to WinUAE.
