A lot of 3D HDTVs aren't great. The 3D effect can break down during fast movement, and the active shutter glasses sometimes create a constant flickering effect. Want a decent 3D? Check out these great sets recommended by Televisioninfo.com.
Samsung Series 7 UA55C7000
Screen size: 55 inches Display type: LED LCD Resolution: 1920x1080 Refresh Rate: 120Hz Price: $4499 RRP in Australia
The Samsung UA55C7000 (or UN55C7000 in the US) is a gorgeous TV with decent 3D emulation. Its 3D effect holds up pretty well under most conditions, the one exception being high contrast areas. The glasses seem to sync up with the TV better than most other sets since there's barely any flicker while the active shutters are doing their thing.
Sony Bravia KDL52HX900
Screen Size: 52 inches Display type: LCD Resolution: 1920x1080 Refresh Rate: Motionflow PRO 400 (200Hz) Price: $5199 RRP in Australia
The KDL52HX900's (or XBR-52HX909 in the US) 3D effect is a bit inconsistent, but when it's working, it's amazing. The 3D effect for background and mid-range objects is great, and the TV really only has a problem with things in the immediate foreground and the cliché "popping out of the screen" effect. The best part: even without 3D, this is a great TV. The KDL52HX900 has great picture quality and Sony's incredible BRAVIA online content.
Panasonic Viera TH-P50VT20A
Screen Size: 50 inches Display type: Plasma Resolution: 1920x1080 Price: $3299 RRP in Australia
If we had to choose one manufacturer for a 3D HDTV, it'd be Panasonic. The TH-P50VT20A (or TC-P50VT20 in the US) might be a first generation 3D HDTV, but it's still one of the best we've seen so far. The effect holds up well even in areas of high contrast or fast motion, and the active shutter glasses don't create an obnoxious flicker effect.
