Quality got better with time,
Verified Purchase(What is this?)
This review is from: ASUS VE248H 24 inch LED Widescreen Full HD 1080p with HDMI 2ms Response Time Aspect Control Function (Accessory)
When I first got this, the quality was a bit disappointing (too red, contrast was out, and I could not get it bright enough) and I could not tweak the settings so watching DVDs on it made it look like RPG or sci-fi effects, and I preferred to watch things on my laptop screen as normal.
But after a few weeks, perhaps something has "worn in", but now the colour and quality of the screen seems a lot better and it's nicer to watch DVDs on this screen than my laptop - the issues seem to have gone. Very pleased as it's now a really great value for a larger screen, and I like everything else about it.
Edit: like others, I had no dead pixels. From my use as a normal everyday computer screen/DVD player, I haven't noticed any difference in top/bottom colours or brightness. And yes sound quality is not great but if you're expecting above-average sound you need to up your price range!
