A quick note, content is generally created to the following color standards so the closer a display comes to being able to match these standards the more accurate the display result:
- Color temperature: 6500K
- Gamma: 2.2
- Color gamut: Rec.709
There will however be many other factors that impact how people might judge a video display system, for example resolution, viewing angle, brightness, contrast, response time, refresh rate, latency. Ultimately it will be the needs of the application that will determine which of these are most important, for example a broadcast display will require excellent color fidelity while an outdoor display will need high brightness and contrast.
