That's not very big when you realize that a 16:9 22" screen has the height of a 18 or 19" 4:3 tube TV. I'd go at least 30 and even then you'll need to sit relatively close to get the full HD effect. Forget all the "million to 1" contrast ratio nonsense (few companies use a standard that actually means anything). The fact is that most fluorescent lit LCD tv's just don;t have the best contrast without dimming tricks that are very distracting. Even at 30" you probably won;t see a big difference between 720p and 1080p so feel free to go with 720 to save a bit if you want (although you might not have many choices in that category). 120hz is more than enough with a lcd screen.
Other than that trust your eyes. Make sure to play around with the remotes and try to look at the TV's in standard cinema or movie mode to compare the pictures. Most are set to vivid mode with the brightness cranked to the max in the stores to make them blindingly bright.
So, my TV of over 15 years- finally decided to die. Therefore, I am now looking to replace it with a flat panel TV. There is so much to choose from,and I'm not a technical person,but I think I know what I want.
Perhaps someone can help to narrow down the models? I do not want to spend a whole lot of money.
Here are the specs I have in mind:
22inch, HDTV, Energy Efficient,2HDMI ports,
Response rate:(min) 60HZ
Contrast Ratio: btwn 15:000:1 to 80:000:1 or better
Any help would be appreciated!
