    BTW, I've just tried the HDMI port - it works with the new driver.

    I added this instructions to my Windows 8 thread, are you ok with this?

    Me? Sure, I'm the second day into a clean install and waiting for a license activation count to be reset when I'd rather be out playing.

    Anyone you help save time on that kind of tedium would appreciate it I think.

    The Ivy Bridge is the newer Intel CPU/GPU combos (Intel HD Graphics 2000/3000/4000 and CPU names have 4 digits instead of 3 in their name). The ASUS EP121 is Sandy Bridge and doesn't natively support openGL 4 in the GPU.

    The ASUS EP121 is Sandy Bridge.
    The Samsung 7 is Ivy Bridge.

    My guess would be the ASUS B121 is Ivy Bridge and if the were true I would buy that one over the Samsung 7 unless the Samsung 7 has Gorilla Glass and a Wacom Digitizer (which I don't think it does).

    For Windows 8 openGL 2.1 is as high a version as I can get installed with the Intel HD Graphics on the ASUS EP121 (.inf mods or not). openGL is built into the driver that Intel supplies.

    I'm not sure what version openGL was support when the tablet was on Windows 7 with the latest version of Intel's drivers; certainly openGL 2.1 or newer.

    I also had directX 11 when I was on Windows 7.

    I'm sure Intel could write an directX 11 / openGL 4 driver for the oldest Intel HD Graphics driver for Windows 7 / Windows 8 that was a mix of HW (Intel HD Graphics) and SW (openGL 4 functions not supported by the Intel HD Graphics chip are done in SW by the CPU) easily enough that would keep this HW robust for some years from now.

    I'm sure the Samsung 7 would support the newest Intel drivers in Windows 8.

    I just tried this.. It works until I turn testsigning off. Then I get no drivers... stuck in 1024x768, and when I look at the device manager, the display driver isn't running and it says it's because it is not signed.

    Any ideas what the problem might be?

    Did you finish the driver installation and THEN turned testsinging off again?

    I don't know.

    I finished the installation and turned test signing off before rebooting.

    I still have the modified INFs with the newer drivers. I am running Windows 8 Pro x64 downloaded from the MSDN site.

    I did it again this morning and it worked.... I did download a new copy of the driver first. Not sure if that made a difference, or if I did something wrong the first time. But, thanks!
