I'm buying a new 32" LCD TV. The 2 models I'm looking at have PC in Video slots. I brought my laptop into the store to see the quality of my charts on them but they both were very grainy and shadowy. This was the latest and best Sharp and Sony TV's but I could NOT get the resolution or quality of picture I can get with a simple 24" monitor. WHY and is there any thing I can do ???? Thanks in advance.
