Can't run El Capitan as guest OS via Parallels beyond 1024x768 resolution

[DavidS13]

I'm using the trial version of Parallels 11 Desktop on a new MacBook Pro with 16gb of RAM. I created an El Capitan guest OS but it only runs at 1024x768, despite me allocating 2048MB of memory to the graphics card. Please see me full post and screenshots here:

Any advice is appreciated

Hello David,
1. Please follow this article and change Scale to fit screen to Keep ratio
2. Then reinstall Parallels Tools - and then try to change the resolution.
