    Intel HD Graphics 4600 - Red dots/lines with hdmi

    MTonina

      Hi, I bought a new hdmi monitor, and I connected it as second monitor in my motherboard. The problem is that I see red dots and lines (with movement) specially with dark images. I tested the cable with my laptop and works well, so I confirmed that the monitor and the cable are OK. I updated the driver to the lastest version. Could it be a problem of the onboard video card? It's strange because the dvi output works properly with my old monitor. The problem is with the hdmi output, and it happens with both hdmi conectors. My hardware is:

       

      Motherboard: GIGABYTE Z87X-UD5H-CF

      Video:

      Intel Haswell-DT GT2 - Integrated Graphics Controller [GIGABYTE]

      Intel HD Graphics 4600

      OS: Microsoft Windows 8.1 Professional (x64) Build 9600

      Micro: Intel Core i7-4770K (3500.0 MHz)

       

      Best regards
