u2410 colors look different

[Austin8868]

I finally got my 3rd u2410 and the colors look amazing compared to my other two. The others look dull and washed out. I don't even want to use them now. I have tried all of the other color modes and they still look bad. The two older ones are refurbished and my new one i bought off ebay used but i think it is also a refurb. Has anyone else experienced this? Would Dell exchange them?

try going to service menu on those older monitor. You will probably be able to squeeze more contrast ratio out of them increasing rgb values. Just be sure to write down or take photo of original values becayse you never know...
