I'm sure bad reviews could be found for just about any product , but just from my personal experience, I've had two Samsung monitors at home and both have worked flawlessly. I've also been using a Samsung 32" flat screen TV now for about 3 years with no problem whatsoever. Great picture.
The newest monitor did have a stuck pixel, but that was easily fixed with a little program I found for just that purpose.
Acer seems to make a nice monitor too. I had an Acer computer about 15 years ago that worked perfectly till it couldn't be upgraded anymore and I gave it to my sister. She still has it and it's working....just way outdated of course.
Best thing to do is to look at different brands in person if you can. Determine what picture looks best to you and go from there. Be aware though, that all the specs given for different brands can be somewhat misleading. I read somewhere that many companies will overstate the specs to make the product seem much better than what it really is.
