Re: Dell Inspiron 5570 Display
It depends on your impression most of all. There are reviews out there that mention poor viewing angles - which is something that low-end TN panels (which is what this is) tend to suffer from.
If you're not happy with the display panel, the best thing to do is return the system and order a higher-end model - the 7577 is the next step up and offers an IPS panel, which will be quite a bit nicer.
Yes, the system will cost more, but part of the reason the 5570 costs less is the lower quality components that go into it.
