Mine (synchmaster 930mp) is like that. I don't mind the channel thing and I never use text so that ain't an issue. Ain't seen any other "problems".
But, after 5 years, it doesn't have a single dead pixel and the speakers are still good despite being cranked up a few times for music playing. You can't say that about too many LCD's.
(PS.. That also included it being bounced around in a suitcase when I took Eurostar from London to Brussels, folloowed by a train to Antwerp and a taxi from the station to this house. I have no complaints and would recommend one to anyone. Wonderful piece of kit)
