What is the NTSC test?

An "NTSC test" refers to tests using signals based on the National Television System Committee analog standard (used in North America, Japan, etc.), involving specific patterns like SMPTE color bars, multibursts, and ramps to calibrate video equipment (TVs, cameras, recorders) for proper color, brightness, and timing, ensuring signals remain accurate during transmission and display despite being largely replaced by digital standards.

Is 1000 or 2000 nits better?

2000 nits is better than 1000 nits for brightness, offering significantly higher luminance that's superior for bright outdoor conditions, direct sunlight, and detailed HDR content, though 1000 nits is already excellent for most outdoor use and general HDR. Higher nit counts mean clearer visibility and more vibrant colors, but 2000 nits is often considered overkill unless you're working in extreme glare; for indoor use, lower nits are sufficient and more energy-efficient.
