First of all I would like to thank RehabMan for making the probook installer, my hp 4540s is working greate. However I bought an Ultrawide monitor from LG with the resolution of 2560x1080. In windows the monitor work perfect, the nativ resolution is used but on OSX the max resolution via HDMI is 1980X1080. The 4540s doesn't have DVi-D dual link/ display port and I don't know how to make this monitor work.
Interesting is the fact that in the notebook specification is stated this :
DISPLAY HP ProBook 4540s:
Internal
15.6" diagonal LED-backlit HD anti-glare (1366 x 768)
External
Up to 32-bit per pixel color depth
VGA
Port supports resolutions up to 2048 x 1536 external resolution @75 Hz
HDMI
Supports direct connection to high-definition displays with up to 1920 x 1200@60Hz resolution and 7-channel audio with one
convenient cable (not included)
However I have 2560x1080 via HDMI in windows. Cam you help me with something for OSX ?
P.S. I have 10.9.4 on HP 4540s ,i5-3230M 2.60GHz, AMD Radeon HD 7650M 2GB.
