This is my first time upgrading a graphics card. I have a pre built Dell PC with Intel Core i5 4440 with Intel HD integrated graphics. I've installed a new 600W power supply and the R7 265 is plugged in the PCIE port and 6 pin connector. When I connect an HDMI cable to the new graphics card and my monitor, the monitor does not display anything/ does not turn on. But with the integrated graphics, it works fine. From what I've researched, the integrated graphics should automatically disable when a new GPU is added, but that was not the case for me. So instead I went to Device Manager and disable the integrated graphics, but the dedicated GPU didn't work. As well as that, in BIOS I could not find any option for me to disable the integrated graphics, and I also didn't find an option to make the PCIE slot the first option for displaying.
Please help. Thank you
