I have scoured the forms and watched 10-15 you tube videos and cant find my answer.

 

I wan to stretch my FSX steam version over 2 -  24" 1920 x 1080 HP monitors.

 

Apparently eyefinity only supports 3 monitors at this point. 

 

Is it still possible to split the screen on to 2 monitors?

 

I have it setup with one screen for field of view currently and the other for alternative things like GPS.

 

This works but I would prefer a 2 monitor stretched view

 

 

You won't find much info. on AMD cards as the recommended cards are Nvidia. But I had 3 6990's a few years ago and it was a nightmare, I also remember AMD saying that they would never support FSX. Just something to remember is you have to detect the display manually to evoke eyefinity.

.  

Don't know if this is still relevant to OP but Eyefinity as of writing pretty much covers any number of monitors up to 6 or 7 I think. 2/3/4/5 whatever.

You can use auto setup (quick) or advanced and select 1:2 as ratio or 2:1 if they are stacked vertically. Using R9 390x getting sweet frames (locked 30) with 4k main screen 2 x 1080p side screens pretty much all settings maxed out except water.
