Martin72 Posted September 19, 2009 Share Posted September 19, 2009 I have a new LCD tv and i like to use it with my Atari system and use the scart input. But i have no display. I tried it with an Atari 600XL and an Atari 65XE (PAL). The same problem occurs with my Super Nintendo, but my old Xbox works well with this lcd tv. I know the computers are good working because with my old crt screen it works properly. I've heard that some old systems outputs a signal that is not in 100% sync regarding what the TV expects from a composite video signal. Older TV's and monitors were not so picky, but a new LCD may not sync properly on a such signal. Does anyone know a solution for this problem so i can use my great Atari with a modern lcd tv.

Rybags Posted September 19, 2009 Share Posted September 19, 2009 Yep, a lot of your modern TVs and recorders that use digital processing of the analog signal have trouble. Problems like: - screen just rolls. - signal "assumed" to be interlaced, which can cause combing effects. - no picture at all. My HDD recorder rolls with the A8 and can make no sense at all of the ST (it does 313 scanlines instead of 312). There's not a great deal you can do other than try another LCD TV. I plan to sometime soon try an "LCD fixer" type modification of the Real Interlaced software driven mode, but the problem is that such a fix can't really be incorporated into much software out there. In the real world, it would be a bandaid solution and a pain to use. And that's assuming it even works at all once I get around to developing it.

+SpiceWare Posted September 19, 2009 Share Posted September 19, 2009 My HDTV doesn't like my Atari VCS or Genesis Nomad either. When I replace it (I bought it back in 2001) I plan to bring my Atari with and try it out on the display models before I decide which one to buy.

+LS650 Posted September 19, 2009 Share Posted September 19, 2009 Sometimes you can use an old VCR or DVD player as a go-between: plug the game system into the VCR's input, and then run cables from its output ports to the TV. Quote Link to comment Share on other sites More sharing options...
Martin72 Posted September 19, 2009 Author Share Posted September 19, 2009 So what i understand is that it is a known problem. Is it possible to make a modification to the Atari computer that it works fine with a lcd tv? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted September 19, 2009 Share Posted September 19, 2009 The LG M227WD is 100% compatible with XE machines and is a great all rounder for vintage machines. It has every input under the sun. All TVs are different and I looked long and hard before I found the perfect LCD TV. Quote Link to comment Share on other sites More sharing options...
Rybags Posted September 19, 2009 Share Posted September 19, 2009 Maybe try normal RF. SCART inputs on some devices won't necessarily have all the lines connected. S-Video is probably the best option anyway - normal Atari video output can't utilize full-featured SCART. Quote Link to comment Share on other sites More sharing options...

SeaGtGruff Posted September 19, 2009 Share Posted September 19, 2009 After reading (in this thread and in others) about all the people who've had trouble using their Ataris with their LCD TVs, I consider myself extremely fortunate that I picked a HD LCD TV that works so well. But after reading Rybags' post, I guess mine "suffers" from combing artifacts-- which I actually like, because it removes 30 Hz flickering.

I think we could do with a sticky or something about LCD TV's which are proven "A8 safe" buys. Quote Link to comment Share on other sites More sharing options...
