In our house, we have our TVs at eye level when seated.
That works best for us!

I think 45 inches high is fine. Much higher and you may want to consider tilting it down a bit but I don't think that is necessary at 45 inches. I think my 46 inch Samsung is about 45 inches high and when in my recliner fully reclined, I only have to look slightly upward...not uncomfortable at all but rather plesant.

Is your Sony 26 or 46 inches? How far away do you sit? By todays standards, I think 46 inches is good to about 10-12 feet and 26 inches is good for your lap! (if you listen to them LOL!)
