IMPORTANT NOTE: Before we get into this section we need to make an important note about use of the HDMI port if you choose to use that for connectivity. The screen features a couple of options you can use, including DVI, VGA and HDMI. You will probably want to use the DVI port for PC connectivity, but if you wanted to use HDMI instead you need to take note of the following. If you have an NVIDIA graphics card and want to use the HDMI at all, whether a straight HDMI > HDMI connection or a DVI > HDMI conversion, you need to make a change to your graphics card settings to display the optimum picture. This is because by default the output range over HDMI is limited by the graphics card, and it can greatly limit the picture quality and in particular the black range and contrast ratio.
When connected via HDMI on an NVIDIA graphics card the screen by default will not look right, and the black range in particular is poor. A change is needed via your graphics card to ensure a full 0 - 255 output when using HDMI, rather than it being limited to a smaller output range of 16 - 235. This applies to NVIDIA cards but is only necessary when connecting to the HDMI port on the screen and is not needed when using D-sub or DVI. A similar change might be required when using an AMD graphics card but the setting is built into their graphics card drivers we believe. For NVIDIA cards the simplest way to ensure a full output range is to use the handy toggle utility
available here. If you run the program you can select a full 0- 255 range quickly and easily.
glad that worked
