Sony HX903 Review?

[Anonymous]

DrDamn:maxflinn:
hmmm , so the lx803 is edge lit , but full 3d .. and the lx903 will be top of the range , full 3d and rear led ?? and about £65k

....

i dont know how sony expect to shift 3dtvs at the prices they are charging tbh ...

No LX903 is edge lit, integrated 3d - the HX903 is rear LED but only 3D ready (needs transmitter). (NB: HX803 is Edge Lit with local dimming - so a step above LX903 range - though it doesn't have the monolithic design).

I don't know how Sony expect to shift 3DTVs when the ranges appear to be designed to confuse and confound
i give up

It's all right for you lot, we have to get our head round these bizarre naming/numbering systems every damn year! Rarely is there any logic involved

That would be something new!

I would be very interested to hear how that works, because normally edge lighting exclude the possibility of local dimming!

Sony has employed a student who is working part time to pay his University fees in the naming department, me thinks.

It released a few MP3 players to compete the ipod, but their names had no recall value......now, what was that name again? Sony NW.. something something.....

From the Sony website 46HX803 page (features tab) ...

"Dynamic Edge LED - innovative locally dimming Edge LED technology optimises the backlight for a superior picture and a superb GigaContrast for the whitest whites and blackest blacks, all within a slim screen design"

I believe the Samsung 8000 series LED sets do something similar (one of the differences between the 7000 and 8000 series - though you'd be hard pressed to discover this from their website).

 

[TKratz]

Ok, that is fine, but doesn't really explain how it works...

afaik the led lights fire down "tubes" (for want of a better word) , which open onto sections behind the screen , thus enabling different parts of the screen to be dimmed whilst other areas are illuminated ..

 

[Anonymous]

however , the term "gigacontrast" in relation to an edge lit lcdtv should be taken with a truck load of salt

hi simon does it get a good review. for those of us who subscribe will we get next issue on the 22nd mate

 

[Anonymous]

Which is tomorrow!, for those of us that don't subscribe we'll have to wait until Tuesday!

Giving this some more thoughts I believe this is an indication that Sony includes the new UV2 panels from Sharp.
They behaves a little differently compared to the traditional LCD panels and might actually provide the possibility of local dimming with a edge LED.

Even more interesting black level is measured down to 0.04 on the Sharp LE820, which is usually unheard of on an edge LED set.

Will be interesting to see how the Sony fairs.

Sorry Max but I didn't

Seen black level values for the HX803 series (dynamic edge lit) measured at 0.08 in a couple of tests. Also just seen a nice Sony brochure with diagram comparisons of how they do the Intelligent Dynamic LED (full), Dynamic Edge LED and CCFL - but obviously I can't link it.

ok ill try harder ....

i think this is how it works , the edge led lights illuminate a passageway if you like , a channel , the light travels through this channel and is released in specific areas behind the screen , giving similar effects to a rear led tv albeit not as good , and allowing for a degree of local dimming , imagine a screen to be a chess board , each square is lit by sections of the led light that has travelled through its channel and illuminates only its designated square .. howzat ?

 

[TKratz]

Much better Max

But I am not certain this is the reason. I think it is more down to how the panel is constructed. The cells are much tighter packed than usual making it easier to control the light passing.

 

[Anonymous]

done a bit of googling , and it seems the "channels" that i confusingly referred to , are in fact called "lightguides" , they disperse the light to designated areas behind the screen , thus allowing for a degree of local dimming on edge lit sets , but the use of special panels as you eluded to is also used as far as i understand it tkratz...

Good point there Chris,

Getting tired of waiting now and I am considering doing the same. My only concern is that the Samsung made me feel

a little dizzy after watching 3D content. How are you getting on with it?

Cheers

I preorderd a 52HX903 on 13th March at £2499 and was told that that price would be honoured when the price increased to £2999. I assume this will still stand with the recent price hike.

I have been told by my local Sony store that they expect delivery between 17th - 22nd August.

 

[Anonymous]

I'm sure they will honour the price, did you pay a deposit or pay in full when you pre-ordered?

I'm still waiting on my 46" which I pre-ordered although not through Sony, I've been told 1-2 weeks, but won't believe anything until it physically turns up at my house!

 

[Anonymous]

A deposit - but the receipt has the original price on - so am hoping all will be fine

I cannot believe the price has gone so high, especially for prospective first time adopters of new technology. Or is that the point???
