Vasi lights and Aircraft lights on 680gtx 3 monitors

Hi, has anyone running a nvidia surround 3 monitors managed to get a good balance of the vasi lights, and AI Lights. I have managed to get mine ok when near to them but at distance still seem a bit large and blurry. Trying various settings either get the runway lights right , the AI right or the vasi, but never all 3. Tried various halo's and settings in cfg

RUNWAY_LIGHTS_SURFACE_SCALAR=0.50

RUNWAY_LIGHTS_VASI_SCALAR=0.5

RUNWAY_LIGHTS_APPROACH_SCALAR=0.7

RUNWAY_LIGHTS_STROBE_SCALAR=0.6

Screen resolution 6054 x 1080

Any perfect settings appreicated!

Also do you change the halo in both locations

ie both

\Microsoft Flight Simulator X\Effects

thanks
