As you can see, my system is nothing fancy, but it works for me. I would have patched the TV into the stereo long ago, except the TV doesn't have variable audio outputs so I wouldn't be able to mute the sound (an important feature for me, since I mute the commercials all the time).

That AIWA is probably new enough to have remote volume control (and many remote capable stereos also have a mute button) if you configure your universal remote to map the volume and mute keys to the stereo, then you should be in business.
If that don't work here is another idea: If your TV has external speaker connections make an adapter that connects them to your stereo's audio in jacks....It may sound crazy but I've done it before with other amplifiers and had it work decently.

IMHO, 32" TVs might have been a fairly practical limit in CRT days, although frightfully heavy CRT TVs were made in sizes up to 40".

Today, the whole scene has changed:
1. Improved resolution allows one to sit *much* closer to the screen... the current guidelines indicate that the optimum viewing distance is 1.5 to 2.5 times the screen diagonal. This works out to 4 ft to 6.7 ft for viewing a 32 inch screen. This size is pretty tiny for most living rooms.
2. Weight has been reduced considerably... IIRC the 40" CRT sets were more than 400 lbs, while a modern 60" HDTV is around 60 lbs.
3. Price has dropped considerably on HDTVs, with some 60" models being sold for well under $1000.

The current generation of OLED screens are probably much better than the first ones (the $2500 10-inch Sony set, supposedly all of which have lost their blue output as of now). However, since I have seen "burn-in" or "image retention" even on a one-month-old Samsung OLED cell phone that was running its demo mode daily, I am indeed hoping that true LED (non-organic) display panels come on the market before too many years go by.

The burn in on the LG WOLED sets are usually caused by having the dealers set them in torch mode with a static display running all day. In the home, it is unlikely that this would occur. Soposedly, the second generation sets are using new algorithms to prevent burn in.

You don't have to be wealthy to own a large flat panel or projection system. It is not uncommon for projection screens to be 120 inch diagonal or larger.

For UHD, it is recommended that the screen be at least 75 inches diagonal to realize the benefit of 4K.

I have an average size viewing room in an average size home and by no means wealthy. Currently using a 70 inch flat panel with separate speakers on both sides and 7.1 surround sound. Because of the speakers, I can only go up to about 80 inches screen size. Way back in 1978 was watching on a 6 foot screen. In the 80's and 90's was watching on a 10 foot screen in normal size homes.

This article describes in detail the new Blu Ray spec, particularly the expanded color space. At the bottom of the article graphic representation.

Large-screen UHD/4K TV sets keep going down in price, so by the time I may replace my projector with a 4K flat-panel, these players may be on the market.

Yup. LG claims they have reached 80% yields without defects with their WOLED 4K panels. The prices should then continue to drop for those as well. I just saw a brand new, LG 2014 last year model 55 inch, 1080P WOLED set available for 1999.00. This thing used to sell for 6K.

I'm holding out until the 4K BluRay players are available and the new sets are fully capable of displaying the new standard, ie:, extended color gamut, HDR, etc. That should come soon, although it might take a while befor we see extended color gamut color programming.

Regarding display technology, I will probably stick with standard LCD if I replace my projector, and watch to see if non-organic LED displays begin to appear eventually. THAT could be the ultimate in quality!

4K Blu-ray is a definite buy, though. That is the main source I expect to have for UHD content.

Yes, OLED's can get image retention just like a plasma display panel. The LG we have in the store also has pixel orbiter and screen image restorer built in, just like a PDP. I have to say that it works quite well. As far as curved displays......We put our Samsung rep through the ringer over this one, and he made a couple of admissions. Firstly, they only did it because LG was doing it. Secondly, the main picture benefit was that it was easier to maintain even color and brightness from the center point to the corners on a curved screen, given the limitations of the full array lighting at the time. I guess it was an easy way to help with the dynamic contrast. So there you go. On a more personal note, they just look stupid.
