re: How big is too big?

80inch television for casting movies, anime,and streams from my pc.
Don't watch tv.

Use a 144hz 24 inch as my main monitor. With 2 24 inch surround monitors.

is there a reason to buy a 60 inch?

not when you can buy a 75 inch. I'm already looking at the bare wall on either side of mine wondering if i have room for a 90.

depends on the room size and how far you will sit from TV. a general rule of thumb - 55" if you are sitting 9 ft away. I have a 60" and my recliner is about 10 ft away, it is certainly not "too big".

Bigger isnt always better with TVs.

The broadcast is coming in at a fixed resolution which results in a certain pixel/inch. This is what constitutes "picture quality". By going bigger youre actually stretching a fixed picture and the quality goes down. Similar to taking a 5" x 7" photograph and stretching it to an 8" x 10". While youll be able to see smaller objects easier the quality of those objects will be Atari 8-bit-tacular.

Also, if you watch any standard-def programming it will look like hammered dog shite on a large TV. Too small and you wont see any benefit to HD programming and it will be hard to make out small objects, especially quick moving objects like a hockey puck or football.

The size of your TV should be based on the distance at which you sit from it and no other consideration taken.



For me, my seating is 14' from the viewing screen. Most of my programming is in 720p. My 59" Samsung PN59D7000 is perfect. Its large enough at that distance that I can always track the smallest objects on the screen and resolve the smallest details yet not so big that 480 or 720 looks like garbage. Viewing angle is tolerable at up to 40 degrees at that distance and screen size which can accommodate 14 individuals in a single row. More if there are seating rows behind.

Viewing angle is more of an issue with LCDs. I have a plasma which maintains color and brightness when viewed off-axis.

multiply your viewing distance (in inches) by .84 or divide by 1.2 and that will give you the ideal screen size. This gives you the ideal 40degree viewing angle. At the very least divide the distance by 2.5 to get the minimum size for that distance.

For example: If my couch is 8 feet (96 inches) from where the TV goes.

Ideal: 96*.84= 80.64"
SMPTE 30 (30degree angle): 96/1.5= 64"
Minimum: 96/2.5= 38.4"

This is a tradeoff for those sitting on-axis as, per that formula, my 14' viewing distance would require a 141" TV which would look like pixelated crap. Even the SMPTE formula would look like crap at 112" screen size.

These formulas were designed for theaters that are trying to give everyone a decent view of the screen even at the expense of the ideal, close-in, on-axis seating. Most homeowners arent tying to entertain multiple parties stretched across a wide area so the people on the end of the couch arent a factor most times so the tradeoff isnt worth it. You would be sacrificing the picture quality for your immediate family so that the few times a year you have 10+ people over they can see the screen.
