50hz only TV...

[25.05.2005]

Looking to upgrade my existing TV.

Want at least a 46" LED TV.

Found a Samsung model for reasonable price but it says 50hz only.

Since I have an NTSC Wii, Gamecube and loads of NTSC DVDs, this TV would not be any good would it?

Would be better going for one that says 100hz?

Cheers for the help.

ps. component connection for these through AV receiver.

Probably means that it isn't a stupid hz TV rather than precisely 50hz.

I'd imagine 60hz is completely fine.

And no, never get a 100hz TV.

Out of interest, what makes you want an LED LCD rather than normal LCD or Plasma? With LED LCDs, you pay a top price for aesthetics (slim cabinet) but often slightly poorer picture quality.

When stores talk about "50hz" TVs, they really mean "Not 100hz/200hz Interpolating LCD". All modern TVs that aren't supermarket cheapies (and even probably ones that are) will accept both PAL and NTSC without issues.

So this is no good?

Will admit to having it on like all the time, and seems worth it to more or less half energy cost. That's what I'm thinking at the moment.

Cheers guys.

My reasoning behind the 100hz thing is that your audio and video will unsync if you use a 60hz signal with 100hz turned on. Not NTSC friendly basically.

The eco-friendliness is probably the best reason to go for an LED-based LCD, so good reason in my opinion.

Unfortunately I can't off the top of my head name a really well priced, brilliantly performing LED LCD. Samsung's have input lag and clouding. Panasonic's are expensive, have no obvious clouding, but don't have too wonderful a black level (their input lag is decent at about 30ms though).

Normal LCDs can also be quite efficient after set-up, so don't rule those out. It is true that Plasma still burns a lot more energy.

I'd have thought tellies that are advertised as 100Hz would just run at 120Hz for 60Hz signals - i.e. if the same telly was being sold in a 60Hz country(where they live 17.5% faster than we do here in the UK), it'd be advertised as 120Hz, not 100Hz.

I've never heard of a 50Hz-only flat screen television. It sounds like more hassle than it's worth to manufacture such a thing. I'm sure there probably were some 50Hz LCD's way back when(probably non-HD, too), but I'd expect all HD Ready televisions to at least do 60Hz.

[speedlolita]

Nah man, they desync.

Hugely noticable in beatmania IIDX but I dunno about other stuff.

[randombs]

Blimey!

Do they desync with all games, or just 60Hz stuff?

[speedlolita]

60hz as it's isn't a multiple of 100. 50hz works as it is. You'd have no probs with 300 or 600hz TVs.

These days LCD TVs that speak of being 50hz only are generally refering to the scanning output you will see on the screen. The input hz for something like RGB Scart say, is a different matter altogether. As said here most TVs nowadays will accept a 60hz signal no probs. even if they only output at 50hz.

For those worried about games being out of sync at 100hz+, these tvs should have either a 'game' mode which switches to a game frendly hz. And /or an option to turn off the 100+hz function.

My TV is 200hz capable and using the 'game' setting I have no synching issues.

Correct. They just promote them as "100hz" TVs in Europe. Same panel.

Any de-synchronization on these 100hz/200hz sets is caused by the extra processing adding input lag.

I don't know of any TV that outputs 60hz as 50hz. That would result in terrible judder and I would come on something like this like a ton of bricks.

Basically:
50hz input -> MCFI system disabled = 50hz output
60hz in -> MCFI disabled = 60hz out
50hz in -> MCFI on = 100hz/200hz output
60hz in -> MCFI on = 120hz/240hz output

My TV is 200hz capable and using the 'game' setting I have no synching issues.

The Game function is most likely cutting off the 200hz processing to speed up input lag. In Game mode you'll be getting standard LCD motion performance.

[SCCAAMMM]

Whatever. It works.

I don't need to use 'game' setting to turn off 200hz either. 200hz is an option. it's not forced.

[Lyris]

Yes, that's the case of many (all?) modern LCDs. Panasonic used to force it on you but thankfully made it optional.
