LCD monitor with 50 Hz pal games
Im a still using a CRT monitor. So it's time for a LCD. On my CRT I lower the refresh rate to 50 Hz to enjoy smooth scrolling with pal games. But I wonder if it's possible to play pal games with smooth scrolling on a LCD Monitor. I always read from fixed refresh rates on LCD's (60 Hz)
So is there a possibility to emulate pal games smoothly on a LCD? |

If you buy an LCDTV instead of a standard PC LCD and use the SCART input then yes. Otherwise you'd have to be very lucky to find an LCD that syncs to 50Hz.
Do not forget the other two problems with LCD's 1) They do not work with Amiga's because they do not sync to 15KHz horizontal refresh so you need a scandoubler (built in for LCDTV's) 2) Their native resolution is usually many times PAL and inputting a PAL resolution signal introduces scaling artifacts. The Indivision AGA & ECS scandoublers scan rate convert PAL 50Hz screens to 60Hz for compatibility but the scrolling is not 100% smooth. Much better to use a tool to promote the PAL games to 60Hz. (i.e. WHDload) Last edited by alexh; 14 December 2009 at 22:17. |

thanks for the hints. Is the game speed unchanged by promoting a pal game to 60 Hz with WHDload? I mean, when I play pal games in 60 Hz with vsync the scrolling is smooth but video and audio are too fast.

Audio : Depends on how the game was programmed, if it uses VBL interrupt then yes, if it used a timer then no. Too fast for what? Most of the time you never notice. |

PAL application + 60hz monitor + vsync = incorrect speed but smooth scrolling.
PAL application + 60hz monitor - vsync = correct speed but bad scrolling. It's either one or the other |

Why part with the CRT monitor, then ? I myself choose to display Workbench on a modern LCD and native mode screen (classic games, demos) on the CRT. Best Amiga emulation related decision I made in monthes !

I am using a EIZO FlexScan L360 LCD monitor on my minimig and it works a treat, the other 2 LCD monitors I tried came up with out of range and one of them is brand new. Maybe a proper list of compatible monitors would be a good idea for anyone who needs a monitor as Ebay is probably the best place to get one if you are aware of what to look for.

Maybe information like this would be useful to anyone buying a Minimig, I have not tried the monitors on any other Amigas as I use those on TV's with the scart lead I made plus I don't have a converter ie 23 pin to 15. |

Lionheart was designed to run at 60Hz wasn't it? I seem to remember it had that option in it's menus? I may be mistaken.
Plus it had it's own HD installer and so is not a WHDload game. |

Some WHDload games have a HD installer (sometimes it's not even "broken"), and the other way round, alexh.
@PiCiJi You shouldn't notice any hiccup with games bearing a vertical scrolling. |

Lionheart wasn't designed for 60Hz. But Flink was, it's switchable to 50/60Hz with the green CD32 pad button.

Wow, one of the few monitors which actually says 50Hz on the Tech. Specs.
http://h10010.www1.hp.com/wwpc/us/en...7-3463255.html Just a shame it isn't 1600x1200 or I would have had one Might look at a HP LP2065 http://h10010.www1.hp.com/wwpc/us/en...1-1815933.html Damn cannot find one for sale anywhere in the UK Last edited by alexh; 16 December 2009 at 21:05. |

p.s. hp are quite craps for ami in native res+scandoubler, as you cannot stretch and move image, those options are simply missing in menu

send emails to "for example" Samsung to produce monitors that can sync down to 15khz and 50hz. Maybe they value their customer that much.
I would immediately buy 2 or maybe 3 such monitors (20"?) if they ever produced one. |

@Chain
There are a lot of crap, HP included, I agree. (For instance, earlier model in this 19" range L1940T miss exactly those features) However, this specific unit has following options under Main Menu/Image control: Auto Adjustment, Horizontal Position, Vertical Position, Clock, Clock Phase Last edited by Lockon; 18 December 2009 at 18:23. |
