Samsung LED tv and eyestrain

bigfreddiel

Hi,

Just had my Samsung UE40C5800 40" LED tv since Friday and its a fantastic picture especially in HD (built in Freeview receiver), but its giving me a splitting headache and eyestrain after only 10 minutes of watching.

I have never had a problem with any TV, or using a PC in the past, just this TV.

Has anyone else heard of or had a problem like this?

I'm going back to the shop I bought it from to see about returning it for a refund - i'm hopeful beause its an independent chain and I have had good service from them in the past. Evidence of this type of sympton tho' would help.


Cheers

Have you got the contrast up too high? Most TVs nowadays are shipped in 'Dynamic' or 'shop' mode where a lot of the settings are maxed out to produce a bright picture. This is not suitable for home viewing. Try setting the picture to 'Natural' or 'Movie'. Even the user manual says use Natural to combat eye strain! The picture may look too dark to begin with but after a while you will get used to it and it will represent the true broadcast signal.

Yes been through all those menus, reduced contrast, sharpness, most auto/dynamic features - had absolutely no change to the headache or eyestrain, thanks for the advice tho'

What's your viewing distance? For an LCD the ratio is around 3 times the screen size, so you should be sitting about 120" away, or 10 feet.

..or a lot nearer according to THX...

However sitting 4ft from a 40" TV does seem a bit ridiculous!

I'm about 12ft away give or take a foot

Is the refesh rate of 50hz likely to cause this affect - my old panasonic 32" was a 100hz tube.

Or is it the fact its an LED - maybe an LCD screen would not cause this affect, my local dealer probably won't go for a full refund but an exchange for an LCD 40" Samsung may be on offer.

Like I have said - in the past i have never had a problem with TV's VDU's I've been sitting in front of a screen of one type or another since the mid 70's - anyone remeber the good old IBM 3270 green screen terminals?

Do you wear glasses?

An LED TV is an LCD TV, the difference is in the use of LEDs for the backlight in place of an electroluminescent panel.

The picture rate on UK TV is 25 frames per second.

Try changing the picture mode to natural or movie.

Thanks for the info on the LED technology

I know the picture rate is 25 frames/sec, but what I'm referring tois the actual creen refresh rate - 50Mhz or 100Mhz - I'm thinking that the 50Mhz rate is causing my eye strain even tho' I can't see it I think my eye muscles must be trying to compensate without me realising it or being able to do anything about it.

And I have tried movie and natural mode all to no affect.
