Teejet Matrix Pro 570gs versus Pro 840gs

[ZXR17]

What is the difference between these two monitors except the size and £ 400 for the larger screen .
Has anyone used both and is the extra cost worth it ?
The spec looks virtually the same or have I missed something ?

Hello,

We use both, 840 is more easy to use because of my oversized fingers, and 840 is nicer when using camera's. But 570 does the same job.
