Still, for a permanent installation, it's preferable to use physical adjustments to get the image to fit the screen to avoid image resampling. This is complemented by extensive warping and keystone adjustment. The HU715Q has a sharp lens with very good uniformity, no visible chromatic aberration, and motorized focusing to fine tune it within its range of image sizes. HGiG gets the display's tone-mapping out of the way and allows the console to apply consistent, static tone mapping as defined by the game's creator and the console's knowledge of the display's characteristics defined by the calibration. It also supports HGiG (HDR Gaming Interest Group) mode, which is not a format but rather a set of guidelines for HDR gaming modes intended to create greater consistency from display to display-especially by avoiding 'double tone mapping.' This occurs when a gaming console or PC is calibrated for HDR on a given display using the console's own picture adjustments, but the display, without knowing this, attempts to tone map the result anyhow. This LG supports HDR10 and HLG HDR formats and offers dynamic, frame-by-frame tone mapping. LG claims the projector achieves 86% of the DCI-P3 gamut, meaning it fully covers the Rec.709 space used in HD video, but not HDR mastered with a wide color gamut (the vast majority of consumer HDR content is mastered in DCI-P3 color).

Still, it makes up for it with vibrant and accurate color within the range it can handle, plus excellent tone mapping and no visible rainbow effect. The light engine is a blue laser/phosphor/color wheel design, which is common for this class of projector but ultimately limits its color gamut compared with three-laser designs when projecting DCI-P3-mastered HDR content. LG's technical prowess as a global leader in display design and manufacture is evident in this projector's highly sophisticated feature set, which is more than welcome from an enthusiast's perspective but has the drawback of being a bit confusing for a typical consumer to figure it all out. The projector comes with a 1-year limited warranty.

LG claims a 20,000- to 30,000-hour lifespan for the laser light source, with the exact longevity depending on each individual owner's choices for laser brightness and picture modes. It uses a 0.47-inch DMD and has a 0.22:1 throw ratio, which are fairly common specs for a midrange 4K UST.

The LG HU715Q is a 4K DLP ultra-short-throw projector with a 2,500 ANSI lumen rating.
