This TV does in fact has Local dimming but its only limited to two zones, left and right, split in the middle. It would be frame dimming but since it has more than 1 zone, its still considered local dimming, technically. It's also mentioned in the specs. It's a bit misleading though.
No , there is no fact here . The TV just doesn't has local dimming .
I think you are confused , because you see a few " columns " that lights up you are thinking it is local dimming because you have been reading some of those FALD TV has "zones " .
These are completely different things .
It is similar to what Hisense called their TV having 2 zones , 6 zones .
Those are not local dimming system , they are software based algorithm used to restrict the APL and they are not effective at all .
They can give them whatever name they have , commonly known as global dimming , frame dimming , etc etc . They don't improve picture quality.
Localized dimming system , need to do 2 things .
First , is to dim the black levels to improve contrast and thus also improving picture quality .
Second , to boost the Highlight of brighter portion of objects objects to improve the Dynamic Range of the picture .
A Full Array Local Dimming can do both , an Edge-lit based Local dimming TV can only brighten the picture .
We have had great Edge-lit local dimming TV before , like the Samsung NU8000 which can boost brightness up to almost 1000 cd/m . GX800 does neither of this .
Also GX800 models have an edge-lit based backlight system ( not to be confused with local dimming ) , even if it has local dimming it wouldn't show up in "zones " .
Remember , the models shipped in our country is the IPS variant , it is different than most of the GX800 reviews you read from the internet.
