The will be less crisp when run in a non native resolution. This is however not very noticable on games with most monitors, but i think it would be quite noticeable when using it for normal applications like txt editing, browsing and so on...

Most of the LCD monitors are programmed to scale only PC-native resolutions. When using a non native resolution on an LCD the picture is blurry and it is hardly an ideal solution for Amiga native screenmodes. My 15" Samsung 151N will display scandoubled PAL modes, but part of the image will be cut off because the monitor incorrectly identifies the resolution as 640x480 or something like that. I would only recommend it for use with a gfx card.

As most of you seem to have Voodoos, like me, i would recommend getting a compatible TV-tuner card and looping the mobo Composite output to Composite In on the TV card.  That way you can play WHD Load games in whatever screenmode you set up in P96.

If the TV card has S-Video In, you could even use that, if you got an RGB > S-Video converter for the mobo's RGB Out.

Failing all that, you can at least get around the 50Hz issue by using WHD Load and the NTSC tool type.

Thanks for all your input on this guys. I think i will stick with my CRT. Its only the missus moaning about about much space it takes up that i thought of changing.

It seems as though there is no quality alternative to the good old fashioned tube.

Cheers.

Considering how few games that actually were produced for being run under NTSC (although many just use the 320*200 part of the 320*256 PAL screen most still seems to have been made for PAL) there will be many issues involved in promoting them into NTSC.

It's not until recently I've decided not to bother about promoting games into NTSC to get full screen... just because most seem to behave odd. The scrolling often gets jerky, the music is, if not only running faster, get messed up, and some games even become completely unplayable.

I blame the lazy coders. It's shown again and again and again. How many times does not the intro pictures make use of the full PAL 320*256 resolution, while the game in itself only makes use of the upper 320*200 part of the screen (in other words, if the NTSC tooltype is set in such cases, intro graphics will be cut of cut of... like with PAL Lemmings)? This bothers me so much. Extremely unproffesional it seems. Not to mention hardware scrolling, how often is it applied? Not too often, I'd say. Oh, let's give the player jerky scrolling! The player doesn't care and it saves us some time instead of using the hardware scrolling! YAY!

Oh dear. Getting of topic, slightly, but, well, my point is that many many many many AMiGA games which had potential of being really nice, and actually in theory were, became bland just because of lazy, or maybe even uncunning, programmers. The games were just too often not presented in a good way although they often had good ides to be presented.

I am still to see one single Bitmap Brothers game run smooth. I hate them for not making The Chaos Engine a PERFECT game by just adding smooth scrolling. AAAAARGH!

That's usually the case, yes. I woldn't' want to run a word processor in a non-native LCS resolution for example, or other things where you need crisp edges and sharp detail.

But for some games you may be fine. I'm playing Half Life 2 with an LCD, but the computer isn't up to running the game smoothly at the LCD's native resolution. I lowered the res to get the game playable, and it still looks pretty nice. I haven't really noticed that 720x400 or so is blurry or anythig on my laptop's 1680x1050 screen, in any parts of this game, but I haven't tried other games with it yet. Someday I'll try some Amiga games in Amiga Forever, but I won't have time for trying that until a couple weeks.

@buzz

those Sony is a MutiStandard Video monitor (QM lines stay for 4-Standard PAL-NTSC/3.58-4.43 and Secam)

I had the 21" model (great monitor for PA pourposes) but its only a Video monitor (no VGA)
