This first resolution list in Nvidia Control Panel lists resolution and refresh rate combinations which are listed in the EDID of the monitor as ‘TV’ resolutions rather than ‘PC’ resolutions. It will usually be listed under ‘Ultra HD, HD, SD’ as ‘1080p, 1920 x 1080 (native)’ as shown below.

You can see how the graphics driver categorises things for the Full HD resolution as that shared with a TV by opening the Nvidia Control Panel and navigating to ‘Display’ – ‘Change resolution’. This is also quite common when using DP, even though that’s a PC-only connection. 1920 x 1080 is connected to an Nvidia GPU by HDMI or DVI-HDMI cable, the GPU may to treat the screen as an ‘HDTV’ rather than a monitor.

Rather it’s designed to give you some straightforward actionable advice which will allow you to optimise the HDMI colour signal for PC use. The aim of this article is not to bog you down with all of the technical fripperies of these different ports and associated aspects. HDMI is designed as a universal signal widely used by TVs and entertainment systems, unlike DVI and DisplayPort which are built from the ground up as computer monitor ports. It’s this quagmire in the middle that many users will find themselves stuck in due to how HDMI is typically handled by PC graphics cards. Unfortunately things aren’t quite as clear-cut as that, and there is a murky middle ground. Further information on supporting our work. Where possible, you’ll be redirected to your nearest store. A user just has to consider the bandwidth requirements of their monitor and choose a port on the GPU (Graphics Processing Unit) and monitor that will support the full resolution and refresh rate of their display.Īs an Amazon Associate I earn from qualifying purchases made using the below link. They’re digital signals that either ‘work’ so the monitor displays an image or ‘don’t work’ so that it doesn’t. You may have heard people say that the image quality of HDMI (High-Definition Multimedia Interface), DP (Display Port) and the now outdated DVI (Digital Visual Interface) are equivalent. Users with Intel graphics chipsets should alternatively look for an option called ‘ Quantization Range‘ in the Intel Graphics Control Panel and ensure it is set to ‘Full Range’.

Refer to the Nvidia section on this, specifically the second half of “Second solution: setting a custom resolution” where the process of using CRU is mentioned. For mobile GPUs or other graphics solutions, including those from Intel, it is recommended that a custom resolution is set using CRU (Custom Resolution Utility). For a CRT, the gamma that relates brightness to voltage is usually in the range 2.35 to 2.55 video look-up tables in computers usually adjust the system gamma to the range 1.8 to 2.2, which is in the region that makes a uniform encoding difference give approximately uniform perceptual brightness difference, as illustrated in the diagram at the top of this section.This article provides guidance for users with discrete desktop GPUs from Nvidia and AMD for correcting colour signal issues that can occur via both HDMI and DisplayPort. Gamma correction is, in the simplest cases, defined by the following power-law expression: Gamma correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems. The effect of gamma correction on an image: The original image was taken to varying powers, showing that powers larger than 1 make the shadows darker, while powers smaller than 1 make dark regions lighter.
