New LCD running in TV mode instead.

[Compman55]

I have reason to beleive my new dells U2414H are running in TV mode on the integrated intel video. How can I tell? I heard the color is not as good when in TV mode, and it does look more dull. On my apple mini they look better.

Read the manual ?

I will be more clear. When connecting these monitor via HDMI, on nvidia cards, they can be picked up as a TV limiting the color output range.

See below for what I am talking about. I need to know how to check the intel driver to see if it is outputting 0-255

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 DisplayPort and HDMI. If you have an NVIDIA graphics card and want to use the HDMI at all 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. In fact when speaking to our friends over at PCmonitors.info they said they had experienced the same issue using DisplayPort on this screen. If the image looks washed out or odd, we would suggest checking the graphics card output first or trying a different connection if you can. We didn't experience any issues with the RGB output when using an AMD graphics card and DisplayPort incidentally.
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. A similar change might be required when using an AMD graphics card but the setting is built into their graphics card drivers. For NVIDIA cards the simplest way to ensure a full output range over HDMI 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.
