I have a ViewSonic VX900 monitor paired with a Radeon HD 2400 connected through a DVI to (2) VGA splitter due to problems with the pure DVI interface (what should be black is green). Both the monitor and video card are capable of greater than 1024x768 (1280 x 1024 @ 60 Hz [1], and VGA: 2048 x 1536 [2], respectively). Yet, I am unable to set the resolution above 1024x768. That option is apparently not available with on my Mageia 5 (x86_64; 4.1.15-desktop-2.mga5) system.
System Settings > Display and Monitor allows for a max of only 1024x768.
The card driver set for the graphical server in MCC is "ATI Radeon HD 4870 and earlier". Monitor is set to "Custom" and Resolution is set to "Automatic".
The radeon-firmware installed is version 20150824-1.mga5.nonfree.

I am wondering if installing the proprietary drivers (ie. FGLRX) might give me more options. If so, which one of the many in Software Management should I install?
When I try to select fglrx-kernel-desktop-latest (x86_64) for install, it wants to install fglrx-kernel-4.1.13-desktop-2.mga5-15.200.1046-7.mga5.nonfree.x86_64 and kernel-desktop-4.1.13-2.mga5-1-1.mga5.x86_64. My kernel version is 4.1.15. I can, though, select the i586 version of fglrx-kernel-desktop-latest, and it appropriately wants fglrx-kernel-4.1.15.
Am I on the right track thinking that installing the proprietary drivers might help? Or, is there something else I can/should do to get the max resolution supported by the hardware?
Thank you for any guidance.
