The average uniformity of white brightness is 6.6% with a maximum of 15.6%. That’s acceptable. On black, the average and maximum are 4.6% and 12.9% respectively.
The gamma curves are not neat at the default settings. The value of gamma is too high resulting in a high-contrast image. Besides, the blue curve differs from the others.
The curves are almost ideal at the reduced settings.
The color temperature setup is not very accurate but acceptable. The temperature dispersion in each mode is within 1000K.
The color gamut is standard for a monitor with ordinary backlight lamps. It coincides with sRGB in blues, larger in greens and smaller in reds.
Besides a high native resolution, the matrix features RTC technology. The response time average is only 3.2 milliseconds (GtG) with a maximum of 6 milliseconds. This is not a record, yet the difference from RTC-less models is colossal. The VX1940w is four to five times faster than the RTC-less models discussed in this review.
The average level of RTC errors is 8.8% with a maximum of 46.9%. That’s a good implementation of the RTC mechanism as TN matrixes go, but you’ll see RTC-provoked artifacts on some transitions. The artifacts are not very conspicuous, though.
The contrast ratio and brightness are all right. Their maximums are close to the best results we’ve achieved with this matrix type in our tests.
Thus, the ViewSonic VX1940w is an interesting product with a widescreen TN matrix. It features RTC, improved viewing angles, and a native resolution of 1680x1050 pixels. It is free from obvious drawbacks. If you prefer monitors with a small pixel pitch, you may want to consider this model.
- Fast matrix
- Wide viewing angles (for a TN matrix)
- Resolution of 1680x1050 pixels
- No factory-set image modes
- Text-based applications (documents, spreadsheets, Web)
- Movies and games (including those that require a fast matrix)
