This is something that is hard to judge because manufacturers rate them differently and it’s not the same playing field between makes. Also, there is dynamic and static contrast. You can’t even compare it from lcd to plasma as it’s not the same thing. The dynamic can be an astronomical number like the 25,000:1 while the dynamic is the true contrast ratio. Essentially, anything over 1000:1 (static) will look very good since you are leaning toward LCD.
