100hertz Sony TV 55 “

My new Sony is supposed to be 100-400 hertz but where the plug socket goes into the tele it says 50Hertz and the picture is good but nothing like it was in store. Have I received a different tv

Are you confusing the Hz of the current with the Hz of the image? (Panel)

It is always better to enter the TV model when you ask.

This has got to be a wind up The Picture you see in store is a special retail demo mode not recommended for home use. The 100-400 hertz is Motionflow and nothing to do with mains electricity.

It’s very probably an entirely genuine question.

The real wind-up here is Motionflow - the software interpolation that varies from 400Hz clean up to 1000Hz, depending on the spec level of the TV, despite all the panels being at most 100Hz panels.

And I defy anyone to tell, with or without instruments, whether a given Sony TV is giving the claimed Motionflow rate or not. (There was a set a few years ago where the silver bezel version was claiming a different rate from the black bezel version. And Sony insisted this was the case. Yeah right. Unless which colour bezel you have affects the picture quality, maybe? )

But yes on the other count, the demo settings these TVs are on in the shop is cranked up to eleven. @pecartl30 can find this Mode if he pokes about in the menus, and can satisfy himself that the set can do this. But the cartoon-like primary colours will soon pall, I think.

Also on a side note - the AC is converted to DC in almost any electronic device, so internally these devices can play around with frequencies as they please. Otherwise there wouldn't be any 144Hz PC-screens or flicker-free studio lights.

Thank you for your help the tv is KD55xF7596.

i researched before I bought and the Sony site appears to say all “New” tv’s have freeview built in but previous models did not and you needed either a digital box or Ariel , however newer TVs should have it built in so no need for these. Is mine an older TV because it is not built in and I have no Ariel and no digital box . The previous tv had it built in.

Hi @pecartl30 To receive Digital Terrestrial channels (Freeview) you need to plug in an TV Aerial or Cable into your KD-55XF7596. Your TV also comes with a Satellite Digital channels (not Freesat) in which case you need to connect your satellite dish to your TV. Make sure you choose the right type and connection to tune in the right channels.

Can we please all be a bit more precise about the term ‘Freesat’? This refers to a particular licensed EPG, with assigned channel numbers and full forward programme details for 7 days, and this isn’t present on these Sony sets.

They do indeed have a satellite tuner, but it doesn’t use the Freesat channel numbers, and only comes with Now & Next by way of an EPG. And many of the channels aren’t free anyway.

Retailers of these Sony TVs are careful to avoid using the term ‘Freesat’, or even of letting potential buyers use it uncorrected - and those that weren’t, initially, had to accept returns over this.

And we must take similar care when posting on the Community to avoid any s

Yes. And if you can’t get any channels on it, try the other one.

NB: By convention, using all caps is SHOUTING, and best avoided, unless you really are shouting.

Re: 100hertz Sony TV 55 “

royabrown2 — Fri, 10 May 2019 09:26:46 GMT

As has been said above, the TV takes in mains at 50Hz, runs its panel at 100Hz (correction: 50Hz), and offers MotionFlow interpolation at 400Hz.

So unless he claimed that the panel runs at 400Hz, yes, he was being truthful.

Hey @royabrown2,

either that or the Rep has no idea about TV tech.

400Hz mains is sadly unavailable in the UK, or even in the US, so Sony are unavoidably restricted to the 50Hz AC coming out of the mains in the UK, and 60Hz elsewhere. But worse, the power comes out of the brick at 0Hz (DC).

However, here is the spec for this TV, which quotes:-

MOTION ENHANCER Motionflow™ XR

(NATIVE HZ) 400Hz (Native 50Hz)

So there’s your 400Hz, right there, and the native 50Hz it looks like the panel actually runs at.

i.e. It looks like he gave you both numbers, correctly.

But I don’t know where you got that 100Hz for the panel from......

Sorry no intention of shouting. I just had the caps locked on on my laptop.

Thank you you for your help.
