Hello all lowyat member, please share your opinion with me.

I'm considering to buy LCD TV to replace my monitor for PS3.

i'm considering between these

1. Sony 40" EX5 rm4999
2. Sony 40" EX4 rm3799
3. Sony 40" BX4/3 rm3299

All full HD & BE 3 engine.
I need good performance LCD tv for PS3 including the output sound.

Is the motionflow 100HZ found on Ex5 series really worth the money?
Which model give the best sound output?

If i were to consider samsung, which model should i buy for great sound output and performance?

I see. I have creative megawork THX 5.1. but the thing is, my speaker only have 1 AUX input. not sure if it supported optical input or just 1/8" jack.

I saw some LCD TV comes with Surround HD. i wonder about its performance. Anyone would like to share?
