Aspect ratio is messing while connecting three monitors to Dell WD19S Docking station

Hi there, 

I have connected my laptop Dell precision 3551 to Dell WD19S Docking station, to which 2 Dell E2220H monitors are connected using the DP port.

In order to increase productivity, I bought an extra wide monitor LG 20WL500 monitor (this has only Hdmi, Vga ports)

So when I connect the third new LG  monitor to the Dell WD19S dock using Hdmi port, the aspect ratio is set to 720 * 576 and it is not showing to beyond resolutions to change it.

But when I remove any one Dell E2220H monitor and keep this (1 E2220h, 1 LG29wl500) the aspect ratio on the wide monitor is set to Full HD.

So I need any solution to use this 3 monitors to it's full resolution/aspect ratio using this Dell WD19S.

To resolve the issue, you must resolve the Display Port available bandwidth.  With HBR2 connection and using DisplayPort 1.4, you can get 1 FHD + 2 HD for a three monitors setup.  See Display Resolution Table:
