The monitor has 100% brightness and 70% contrast by default. I lowered them both to 55% to achieve a 100nit brightness of white. Dark halftones are distinguishable at any settings while lightest halftones merge into the same color at a contrast of 90% and higher. Color gradients are reproduced without banding but there is some slight noise in dark halftones like with the ASUS MB19SE.
The average brightness uniformity is 5.4% for white and 4.4% for black. The corresponding maximums are 18.4% and 15.3%, respectively. That’s a very good result.
The gamma curves are somewhat sloppy at the default settings, deflecting from the ideal curve.
Alas, the curves retain their shape at the reduced settings. The value of gamma lowers somewhat.
The color temperature setup is just acceptable, the difference between the temperatures of grays amounting to 1000K in each mode. Dark halftones are always colder than light ones.
The color gamut is somewhat unusual. As opposed to most other monitors with ordinary backlight lamps, the color gamut of the VA1903wb coincides with sRGB in reds and differs from it in blues.
The response time average is 12.9 milliseconds GtG with a maximum of 22.7 milliseconds. These are good results if you compare them to other RTC-less monitors, yet this monitor is far slower than TN-based models with Response Time Compensation.
The contrast ratio and brightness are normal. The monitor will satisfy most users with these parameters.
So, the ViewSonic VA1903wb is yet another average-quality widescreen monitor with a slow matrix. It has neither serious defects nor special advantages. Everything is average in it: exterior design, color reproduction setup, brightness uniformity, etc. It’s just a regular work tool.
- Slow matrix
- No digital input
- Text-based applications (documents, spreadsheets, Internet)
- Movies and games that don’t require a fast matrix
