    My machine is from Best Buy and after recent update of graphics drivers working just fine with any game including opengl stuff.

    I put in an intel 320 120gb ssd and ditched the express cache and it runs really sweet.

    I do run external monitors at home/work ( using both builtin and external lcd ) and color calibration etc is fine driving the external monitors via vga hookup. ( So I am using the samsung mini vga connector to regular vga hookup ).

    My external monitor at home also supports HDMI ( an acer 23 inch 1920x1080 ) but when I use that to drive the display it forgets the color calibration.

    Typically I can use win 7 and re-do display calibration of HDMI driven output ( turn gamma way down ) and it is good temporarily.

    As soon as display turns off temporarily and/or screen saver kicks in then I am back to where the external display has forgotten the color calibration. So you can do it again ... etc.

    This does not happen when driving it with vga output.

    Ideas anyone?

    Thanks John

    With the intel graphics one needs to disable igfxpers.exe from the startup. However, I don't know if this will work with the switchable graphics.

    can the chronos drive both a HDMI and VGA external monitor at the same time in win7?

    And if it can will it drive laptop LCD + HDMI + VGA, (3x or triple) screens?
