Author Topic: LED TVs - 50Hz vs 100Hz (Read 10393 times)

What's everyone's opinion on 100hz vs 50hz LED tvs?

I've seen a good priced Samsung 32 full hd for £360 http://www.amazon.co.uk/gp/product/B003DNSJ22/ref=pd_luc_mri?ie=UTF8&m=A3P5ROKL5A1OLE

Is 100Hz really worth the extra money? I thought this was a great price delivered for a full 1080p LED tv otherwise?

50hz can be very dangerous to epileptics / photosensitive people. the fact they still sell them amazes me.

100hz every time.

100hz and no less.... Seriously. 50hz shouldn't be allowed

Cool cheers guys.

Bought this instead:

LED 1080p 100Hz 32".

It actually amazed me how major retailers like Currys, Comet and PC World refuse to put the basic specification of the TVs on their website. You have the size and the you have to really look for the resolution, but no mention of the Hz value!

Amazon and Richer Sounds had the best and most detailed specification.

if you're sensitive to it (like I am) you can see 50hz a mile off, best test is to stand at 90 degrees to the telly, and look straight ahead. a 50hz will flicker, where as a 100 hz will not.

its not the actual 50hz flash, but the 25hz 'sub flash' that occurs at the edges of the screen. VERY dangerous.

For the best quality, smoothest picture you really need a 1080p panel that drops to 24 fps, everything else is just interpolated by either the blueray player or the tv.

Finding the spec of a 1080/24 tv is even harder than finding the refresh rate on curry etc websites. You need to check each manufacturer then go shopping at curry knowing exactly which model number you want.

Understandable. Took everyone's advice though and got the 100Hz

It was more money, but it's also going to be hooked up to my rig for movies.

definitely the right choice.

Did not know that

- Cheers. The more information you find out about TV specifications, it seems the more you need! Just shows you what the retailers 'keep' from uninformed customers though in the hope that they will just buy anything..

Another trap, sometimes you see catalogues / online companies advertising TV's that are apparently the same as high street, but with perhaps one letter missing and a significant saving, i.e telemake 134i is high street, but the catalogue offers telemake 134

there cheaper but seemingly identical TV is often a foreign market model, with a lower spec.

case in point - my CD player is an Arcam alpha 7 se+ you could also buy a seemingly identical Alpha 7, the SE and SE plus were however vastly better players, but £50 more expensive.

Yes.

I also noticed to limit the amount of price matching the big stores need to do, they have their own codes for the same TV model.

So a Samsung could be online - official Samsung code: UC326500

Comet / Currys / PC World code UC326500C

When you say to them you are £200 too expensive for the same set, they say ours is a 'C' model so not the same and therefore exempt from price match. (yes, yes I know there are different business models here with the online being able to discount more etc).

Bought this instead:

Arrived today. Quite impressed! I ordered it on Saturday evening

Will have a play with it tonight when I have got some other work out the way. I will also try the TV out.

interesting.. turns out that the flash rate doesn't affect LCD TV's as much, because of the different way they work to CRT, so its only 50hz CRT thats dangerous. you just dont get quite such a smooth picture on faster things like sports.

Yah I read something similar too. CRT's are just monitors, where as modern LCDs are computers with monitors attached and when they run at 50Hz they artificially reproduce the other frames to make it smoother.

I'm glad I bought the 100Hz though, it has more features on it (Internet@TV, HDD, Wireless, Iplayer etc).
