How to judge a sitting room to suit how old TV?

The TV nowadays needs a consideration far from " how old "

The sort of television of vintage cerebra bag is picture tube is become picture, this thing has a drawback, that is unsharpness.

If distance picture tube is too close, shake with respect to what can see picture and the spot in image -- and greater television, shake and the phenomenon of spot is more apparent. So in those days the television is right " big " it is limitary -- the distance is bit further, do not look to give picture flutter.

The liquid crystal television nowadays is nonexistent this kind of problem, the definition of screen, also have nothing to do at the size of the television, far and near. When buying a TV set so, do not need to consider again " too big " problem. Conversely, we should be afraid " too small " problem.

The television of any period, exist cannot too small issue -- too small look not clear!

Accordingly, vintage TV opportunity sets an interval to us -- both neither can be too big, cannot too small. And the television nowadays, did not have " big " limitation, accordingly we need to consider the smallest measure only, want to be more than the television of this dimension only, it is appropriate -- of course the habit of everybody is different, somebody loves to look big, somebody loves to look small, this is indifferent to, what restrict you anyway is yourself, not be a television, we talk about general character problem only.

About the smallest size of the television, have a very simple estimation formula: Watch distance *15= inch

Explain, it is the user distance to television screen (unit: Rice) by 15, the gotten the smallest size that wants a TV set namely as a result (unit: Inch) .

Here notices, it is the user distance to television screen, is not the sofa wall space to TV wall, of the ply that sofa back of a chair involves inside this and television put the position (if be being placed on TV ark, the distance wants less than be being hanged on the wall 20cm to control) .

Cite a case, the user distance to the television is 3 meters, the TV set that then we require is the smallest dimension is 3*15=45 inch; If be 2.5 meters, that television cannot be less than 2.5*15=37.5 inch.
