Mobile HD4000 and HD4600 1920x1080 at 120hz


I would like to know whether the Mobile IGPs in the Ivy (hd4000) and haswell(4600) are able to output 1920x1080 at 120hz via displayports(either 1.1a or 1.2)? So far I have only been able to find the maximum resolutions at 60hz; however, nothing on the 1920x1080 maximum hz. 

I want to order a laptop and I need to be able to work with 120hz through an external monitor; however, the optimus or enduro technology sends the signal through the IGP and not the Nvidia or AMD cards. 

Thank you for your answers :)

FSX & HD 4000

Cannot get FSX to go into 32 bit graphic mode with HD 4000 even though it allows selection in its graphics display setup section. (FS2004 works fine BTW)

FSX always goes down to 16 bit mode as soon as I'm full screen mode or windowed mode. FSX has a Display.cfg which lists older Intel chips. Maybe need a new entry? Anyone run into is issue?

Havok - Error when removing an Entity from World when Visual Debugger is on

When I attempt to delete an entity from my world while the visual debugger is turned on my application aborts. If the visual debugger is turned off then everything works fine. Is there anything I need to do so that the visual debuggger dosn't crash my program?

When I debug it this is always the last line of code to run before the crash happens.


P.S: This is my first time posting, so I apolgoies if I break any of the communites rules.

GL_INTEL_map_texture not working after driver v15.31

I just noticed that the GL_INTEL_map_texture OpenGL extension, specifically, glMapTexture2DINTEL() returns null with the newly released driver v15.31 (

I was wondering if anyone else noticed this or has a work around.  The Map/Unmap functions are otherwise straight forward to use and perform well.

Extra information:

The extension string 'GL_INTEL_map_texture' is present as are the proceedure addresses.

glGetError() return GL_INVALID_OPERATION after calling glMapTexture2DINTEL()
