Do you really need built-in speakers? They are always naff, they make the monitor more bulky and separate speakers with a sub-woofer offer a much nicer experience.
Is the screen response rate and important to you? (i.e. do you want to play games on it?)
Is input lag important? (i.e. if you play games do you play FPS/twitch games?)
Is colour accuracy important to you at all? (e.g. do you want to accurately edit photos?)
And how do you feel about viewing angles? (i.e. will you use it to watch movies or show photos with other people who may be sat at different positions? Also helps with editing photos)
Would prefer speakers as I don't need top quality sound.
Don't want to play games.
Would like to have a reasonably accurate colour
Viewing angles are un important as it will be just me using it.
It will be used as a workstation solidworks, AutoCAD, vectorworks, sketchup, adobe.
