My mum' decided to buy a new TFT Samsung 151S and I want to make sure the decision is the best possible : 1. Heard about those " dead pixels " and I want also to find out a percentage of devices that are affected by this problem .. 2. As a customer is that right to be able to test the monitor before paying ? [ refer to Nokia Monitor Test ] ________________ II . Question We're you able to test your TFT before buying ? 1. Yes 2. No 3. Haven't tried poll option doesn't work Thanks .
