    intel HD 3000 HDMI port does not work with DELL U2410 and benq G2411HD

    live4love

      My laptop lenovo V470 has integrated graphic card only - intel HD 3000 embeded inside 2630QM CPU, installed with windows 7 64bit and intel driver

      15.21.5.65.2266. The HDMI port does not work with some LCD and TV. Windows can not find monitor at HDMI port, thus no signal received in monitor. I tried the latest driver 15.21.12.64.2321 from intel site, also failed.

       

      The HDMI port is working with:

      Philips TV 42PFL3609: HDMI 1.3(not sure), 1366x768
      Not working with:
      DELL U2410: unknown HDMI version, 1920x1200
      benq G2411HD: HDMI 1.3, 1920x1080
      Hisense TV LED32K11: HDMI 1.3, 1366x768
      Note that all these monitors work fine through HDMI port of NVIDIA G200 graphic card on another computer.
      Is it a driver problem? I heard some guy fix HDMI problem by downgrading the driver. Any versoin suggested for this?
      Thanks!
