While most Blu-ray UHD content is available in HDR10, a lot of 4K streaming material is still only 4K SDR. The VW915ES had no problems delivering sharp detailed 4K imagery.
With the introduction of the Apple 4K TV, the amount of HDR streaming movie content has increased dramatically. 4K HDR content can deliver expanded color space with better highlight and shadow detail, but even the brightest HDR projectors can struggle to faithfully reproduce HDR.
The new Dynamic Contrast Enhancer feature which does frame by frame HDR tone mapping did a great job balancing the need to deliver respectable full screen brightness while still displaying a good amount highlight detail.
Sometimes brighter highlights are still clipped, but Sony believes this necessary to keep most of the image on screen as close to the director’s intent as possible.
Unlike most HDR compatible projectors, it was rare that I felt a need to make any manual tone mapping adjustments of the VW915ES during HDR viewing. While I left the Dynamic Contrast Enhancer set to LOW during most of my HDR viewing, occasionally there was a need to set it to HIGH when watching dimly mastered HDR material. This could be done quickly with the press of a button on the remote control.
While the VW915ES could only produce about 90% of DCI-P3 color space, I found HDR colors still appeared rich and vibrant. Unlike some competitive home theater projectors, the VW915ES does not use a color filter to extend its color gamut. By using a color filter on a projector, you can achieve full P3 coverage, but you typically sacrifice some brightness.
While we focus a lot on color gamut (Rec709, P3, Rec2020) we also need to be just as concerned with HDR color volume. HDR color volume is a combination of color gamut and color brightness. The colors look more saturated when they are brighter. When viewing HDR on a projector, I personally prefer the extra brightness over the wider color gamut.
