I don't know about every TV but I've never heard of any that have only have a real signal strength meter. All that I've heard of or have personal experience with have a signal quality meter. I know someone with a Sharp and it too has a signal quality meter.
Every Sony I know of has a diagnostic screen that has an AGC reading. AGC is a real signal strength meter although it reads in reverse, i.e. the lower the number the stronger the signal. The AGC gives a reading as long as it can phase lock on the pilot carrier which appears to be down to 13 dB SNR or so. That gives a signal strength reading on stations that are slightly too weak to decode. With my setup, the strongest signals I receive give an AGC reading of 29 and weakest decodable signals around 65. Some very weak signals read as high as 72. I have verified against my spectrum analyzer that you can peak your antenna with the AGC meter. It can read a difference of about 1 dB.
If you were to choose a Sony you should be able to ask on one of the owner's threads about the diagnostic screen. The diagnostic screen on my Sony reads RF channel, Frequency, Uncorrected Errors, SNR, AGC and a few other things.
The only thing I wish Sony had included was a signal quality reading on the main screen Display info so you could have that by pushing only one button. The diagnostic screen is buried down in the menu system.
