A perfect TV for a boat

This is a bit long, but I need to share my disappointment. I did installed a LG 22 on my bunk, mounted a bit high to allow more viewing spots, but am somehow dispointed. Since seated space is limited, like any other boat, every spot count when watching a movie by those rainny nights. This TV has a limited vertical angle (manual says 160dg V) making any spot close to it innefective. If you look any small LCD from a low angle, says 15 degree, you'll notice a picture almost black or "sepia like", , and this makes for even more limited viewing spots. I did research several TVs and found only models above 26" not presenting such problem, but this size takes 140W, just too much. There is no good LED on small size. I learned there are several LCD technology, but market ask for cheaper unities, so the only TV that provide a perfect vertical viewing angle is AQUOS at 19", the closest size I found ... a bit small. My perfect TV would have, at minimum, a large Vertical angle LCD (100% of them has almost 180dg Horizontal), around 24", using LED at backlight, accepting HDMI and Video Composite. 12V powered would be a must. Have you found similar problem, have yu fixed it ? What TV you have installed ? Thank you for your thoughts .....
