ViewSonic X10-4K Measurements

Brightness. In the Brightest color mode with Light Source Level set to Full, the ViewSonic X10-4K measures 761 ANSI Lumens from its LED light source projecting a 92-inch image. The two User modes measure 712 lumens, Gaming at 714, TV at 681, and Movie at 699 lumens. When changed to Eco mode, the light output drops about 18%. While the lumen numbers seem low (ViewSonic rates the output at 2,400 LED lumens and 1,000 ANSI lumens), the perceived brightness of the projector is good and goes well beyond what the ANSI measurement suggests. I had no trouble watching the US Women's National Soccer team win the FIFA World Cup in the morning with curtains open in my living room.

All measurements below were taken at default settings. Note that our ANSI lumen measurements were made and rechecked with multiple luminance and chroma meters but still came up short of ViewSonic's claim of 1,000 ANSI lumens. ProjectorCentral is investigating and will amend this review as needed if other information comes to bear.

Out of the box, the X10-4K was very blue, even in its Movie setting. After calibration, measurements showed a slight green tint but it was not viewable with source material.

ViewSonic X10-4K ANSI Lumens

MODE Full ECO
Brightest 761 628
TV 681 550
Movie 699 573
Gaming 714 585
USER 1 712 584
USER 2 712 584

Brightness Uniformity. Brightness uniformity measured 79%. With a white test pattern, there is a perceptible hot spot at the bottom middle of the screen, while the top corners are noticeably dim. This was difficult to spot on regular content.

Fan Noise. ViewSonic lists fan noise at 30dB for Full and 26dB for Eco. There's little perceptible difference between the two and unless you're within a foot of the projector, the fan noise is negligible. In High Altitude mode, recommended for 1,500 meters or higher, the fan noise is easy heard and could be distracting during quiet passages.

Input Lag. In 1080p with frame interpolation on (in high, mid, or low), the ViewSonic has an input lag of 133.7 ms. When frame interpolation is off, the input lag drops to 67 ms. The results were essentially the same with a 4K lag meter, showing 66.9 ms with FI off, and 133.6 ms with FI on in any setting. These measurements carried across all picture modes; putting the projector in its Gaming preset, for example, doesn't affect the input lag in any way.

Input lag of 67 ms is far too high for any serious gamer, especially for eSports-style games like Overwatch, or fighters like Mortal Kombat 11. If RP games like Divinity: Original Sin 2 are more your speed, you shouldn't be hampered by the input lag.
