Terrain shows up as "white" in distance

Hello All,I've recently changed my standard CRT flat screen with a flat panel monitor. I changed the resolution to the native resolution of the panel. My issue is after taking off the scenery in the distance appears/flickers white. I changed the fsx.cfg max load to 4096 as it was previously.I'm not sure what other terrain/scenery tweaks I should change. I honestly have no idea what could have changed minus the screen resolution. Any ideas?Thanks in advanced,Rob Sciarrino
