So you have Comcast's HD service, love golf, and have already picked up one of the latest 3DTVs from Samsung or Panasonic. Everything you need to enjoy The Masters this week in 3D, right? Well actually there is one little detail you need to know -- otherwise it'll look like the image above. This 3D presentation came about pretty fast and Comcast, Time Warner Cable and others have yet to update set-top boxes with 3D aware firmware. The good news is that frame compatible side by side 3D doesn't actually require the box to know what's going on. The bad news is that the set-top box won't tell your fancy new 3DTV what format the 3D is in. Luckily the fix is simple, you simply need to tell your TV what type of signal it's receiving. Exactly how to do it will depend on your TV, but it shouldn't take too much digging around in the interface to figure it out.
