Best LCD TV-set for the C64?
Most people I've talked to, doesn't recommend a LCD TV as a C64 monitor, but my question is: which is the best one? I'm looking forward to a slick C64 setup with 1541U and a very portable monitor. :D

Not that I think it would be a very great idea, but just out of curiosity: Would it be easy to modify a C64 to run at precisely 50hz? |

What we need is a magic box with analog video/audio in and digital out that can do all the things we want, ie;
o Correct interlace handling
o Buffering of images to allow for slight reduction or increase in framerate by just playing slightly slower/faster
o Real telecine / inverse telecine frame rate conversion
o Scanline / PAL emulation
o etc...
Any hardware hacker with a year or two to spare? :)
(Come to think of it there is probably commercial hardware that does much of this, but I bet it costs a shitload).
EDIT: Oh, and for the second feature to work it must also remove or add black frames whenever it can to compensate :)

Sasq: Still, with all that, realtime is a no-go. :-( |

@WVL: this is strange bcoz I tested a monitor like yours before buying mine, and both worked. On the downside the Neovo has a 25ms refresh rate (thus a bit blurry) and the c64 colors feels a bit strange (even after adjusting it a lot), but I got used to it. I'm not sure if it's still being produced.
Also... Hollowman/FLT has a working lcd tv configuration afaik, ask him for the type.
If an lcdtv/tft monitor has explicit PAL 50hz support on it's feature list then that's a very good sign, but as someone stated before me, you must try it to be really sure.
Also, I kept an eye on this promising c64-vga project: http://www.commodorescene.servebbs.org/vga.html
but it seems to be dead for some reason. :(

Yes it would be mostly for watching demos - but some of the features could of course be used realtime.

In 2004 I bought an Andersson Y1/02 15" TV and in 2006 an Andersson Y70HD 32" TV. Some googling says that they are probably made by a Turkish manufacturer and then sold under the Andersson name by netonnet.se
The good thing is that they are cheap and have plenty of different inputs and the ones I have work fine with c64. But they do lag a bit when watching 50Hz effects, so I can't recommend them fully. |

My external tv-card has worked good enough for me the past three years (not necessary to route via a pc) on my li´l 17", but I guess when going down to these anal bits on delays and stuff it is as sucky as anything else.
Hollow: is the picture flickering _at_all_ with those Andersson screens? |

To repeat my question... ...but phrased slightly differently:
Wouldn't it be easier to make a mod for the c64 so it runs on 50hz than building all kinds of advanced converters to make 50.12 -> 50 artificially? I guess it might affect the frequences on the SID or something too, in that case, right? ...but that effect would be quite small anyway, and hardly noticeable, right?

Probably, yeah. You'd only have to swap the crystal, i think. But I wonder if a crystal with that kind of frequency is available at all. Also, the sound will be off-key. |

this topic is interesting and i have missed it all this time.
the idea of swapping the crystal to get exact 50 hz is interesting. what we put in its place does not have to be a "crystal", it can be a highly tuned separate oscillator circuit.
if the frequency difference (50.12/50) affects all frequencies generated by by SID linearly (i don't know if this is true. i am not even sure if SID uses the clock as a source to its audio oscillators, i doubt that it does) than the off-key-ness would be still quite smaller than a half step in chromatic scale (i.e the difference between c and c#). So my hunch is that, this should totally be doable. |
