Back to Costco today. Now thinking a 50" TV will be best. Samsung will be the brand. Did some checking and think we'll get a rear-lit model instead of a side-lit. I much favor picture quality over thinness and power use.
Looks like the rear-lits cost less, even tho they cost Samsung more to make.
Also looked at "full motion" wall brackets. They only go up to a 47" TV capability. So what happens if I put a 50" TV on it? Do I just lose some moving range or is the restriction weight based? It's rated for 60 lb, IIRC.
