The monitor has 100% brightness and 50% contrast by default. I reduced them both to 41% to achieve a 100nit brightness of white. If the contrast setting is set higher than 65%, lights become indistinguishable from white. When it is set at 35% and lower, darks merge into black. It means you should be careful when adjusting the contrast setting of this monitor to avoid losing some of halftones. The brightness is regulated by means of pulse-width modulation of the power of the backlight lamps at a frequency of 400Hz.

 

The average brightness uniformity is 6.5% on white with a maximum deflection of 22.5%. That’s acceptable. For black, the average and maximum values are 4.3% and 14.5%. There is a brighter band along the left side of the screen on both black and white.

The gamma curves are rather neat except that the blue one goes higher than the others.

There is no positive effect from the reduced settings. On the contrary, the left part of the blue curve becomes almost flat, indicating problems with the reproduction of darkest halftones.

The color temperature modes are set up with varying quality. The temperature dispersion is within 500K in the “7500” and “sRGB” modes, but gets as high as 1000K and more in the other modes.

The monitor’s color gamut is virtually identical to that of the above-discussed monitors.

The response time average is 15.2 milliseconds GtG with a maximum of 32.8 milliseconds. That’s a normal speed for a TN matrix without Response Time Compensation.

Having a lower specified contrast ratio in comparison with other monitors, the AccuSync LCD93VM turns to be no different from them in this parameter according to my tests.

Overall, the NEC AccuSync LCD93VM is a typical representative of the inexpensive category.

Highs:

  • Correct color reproduction

Lows:

  • Slow matrix
  • Unhandy onscreen menu
  • Unassuming exterior design
  • No digital input
  • No factory-set modes

Recommended usage:

  • Text-based applications (documents, spreadsheets, Internet)
  • Viewing and simple editing of photographs
