clouding , a few reviews ive read have found it on the 55b7020 , and theres been a few posts on here about it , one owner was very dissapointed with his one .. it seems with the larger screen , the led lighting has to work harder to illuminate it ,and light seepage (clouding , backlight bleed ) can occur . im not putting you off it , but thats what ive read , id check it out before buying , maybe get a return guarantee ?
