I have just bought a Dell Inspiron 5570 and I am very dissapointed by the quality of the display. It is Full HD and the image quality is worse than the one from my old laptop that is just HD. Do you have any similar experience with this model or do you have any recommendations for improving the quality of this 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.
I also have this issue and it's very upsetting. Not what I was expecting from a ~$750 laptop made by what I thought was the top manufacturer. I also have a 6 year old entry level HP laptop which cost under $200 and its display looks better. I think it also has a slightly better viewing angle than the Dell's. I wasn't expecting IPS, but still... I'll try to upload a screenshot so you can see what I mean. The background, which should be white, is a grainy newspaper gray. I mention that all my drivers are updated, as is Windows, and I ran a Diagnostics test which came up with nothing. Clearly this is just the normal quality of these Dell displays... I'm going to return my laptop unfortunately, I like everything else about it, but I can't live with this depressing display. Are displays from other manufacturers (HP,Asus,Lenovo) in this price range (under $800 for 15",i7,8gb,1tb+128gb ssd) better? Would you recommend any in particular? Thank you.
