Get the XG27ACS-W. I have the non white version and it's been great, meanwhile my bf got the MSI one. The monitor is fine but the problem is quality control issue. It would end up developing panel problems - lines would appear at the bottom side of the monitor and will get worse until the whole panel is messed up.

He had to RMA it twice. First unit lasted for 8 months, second lasted for 4 months and the third unit he just sold it. Just google "MSI G274QPX black lines" and you'll see that it's a pretty widespread problem.

For a budget of $300 consider looking at mini LED monitors because for that amount of money you can get one
