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

@BitBreaker: those speakers!! *drool*
I have a question regarding this LCD TV I use for my C64 at home...
It's not the best one around of course... just a crappy brand (Alba) I bought from Argos to replace the ~25 year old CRT I always used, but sadly came to an end of its life. :'(
This LCD TV has both AV and HDMI support. Currently my C64 is hooked up to it via AV cables... but the output quality is really shitty, and you get that "jump" frame problem after around 20 seconds as people have mentioned above. I was thinking of switching to the HDMI method... is that possible and is it better quality output? ... just so I don't have to go out ordering the S-Video/HDMI convertor that I currently don't have, in the case that there is no difference to quality. |

It might not be the best, but very portable..

This is quite small but works ok with c64 including smooth scrolling. It only accepts composite, but with this screensize its not a big problem.
It evolved into integrated display on my c64c

Quoting CruzerBtw, about Frantic's idea of modding a C64 to run at 50 Hz - wouldn't it be easier to mod a screen to run at 50.12 Hz?
A problem with either approach is that the computer and the monitor would have different ideas about the correct colour carrier frequency.
How about TFT/LCD modules in embedded systems? Has anybody tried changing the frame rate of the display in, say, a jailbroken tablet? One use case would be to run vice with perfect scrolling and no tearing, but with some kind of USB S-video grabber it might also be feasible to use the tablet as a display for a real C64. |

regarding the skewing problem, taking inspiration from here:
http://www.raphnet.net/divers/commodore64/index_en.php
see section "Composite video and and LCD TV", I got rid of part of the video signal in the V-synch area using LM1881, and magically the screen stopped in a still position. I still have problems in displaying proper colors, especially red is awful, but at least I get a still screen. I'll try to post the circuit I used after I optimize it a bit. |

After a lot of experiments I managed to gain an even higher quality without flickering using an interface circuit. But I still have troubles with red color display. I see red as grey. Anyone knows why? |

These new TVs still suck. Tried 3 lately.
The first couldn't scroll properly without jumps. There was no way no tell it not to automatically adjust the backlight to content. Crap colours, visibility and sound. But at least it didn't try to deinterlace. Anyway, some manufacturer I've never heard of from Europe(?).
Then there was some model of Samsung I think. Impossible to get it to not deinterlace. But scrolling worked. Unfortunately when it detected a black screen it's switched off the back light, so a flashing cursor gave an interesting effect. This could slightly be reduced in movie mode where it dimmed slower. Lot's of not so useful "effects", except maybe for the picture zooming. Picture ok, but on low backlight it was not "uniform" everywhere (darker right low part).
Now here's one from Sharp. Also impossible to get rid of deinterlacing. At least it's not messing with the backlight. This also doesn't like black screens, shifts horizontally a bit when it comes back. Scroll jumps sometimes. Picture ok.
The best is that the last two had noticeable lag even when typing at the BASIC prompt due to some picture processing. Even after I switched most stuff off. Playing games must be challenging on these ;)
It's a bit disappointing. |

I just got a Samsung lw20m21cp, and I can tell you this is the best friggin monitor that I ever had.
the CRT feel of subtle noise and swim is there yet its crystal clear, and interlace is very subtle, yet its LCD. oh and perfect 50hz screen, with all analogue inputs there is.

Instantly went on Ebay-Kleinanzeigen and got one for 25€.
Works like a charm and the picture looks solid to me.
Could not notice and jags and tears so far. |
