A ‘4K’ UHD resolution combined with a ~32″ screen size provides an excellent combination of immersion and pixel density for gaming, alongside a high level of ‘desktop real estate’. The Philips 329M1RV is focused on the play side of things on both PC and new generation games consoles. With HDMI 2.1 capability, the monitor allows the PS5 and Xbox Series X to leverage a ‘4K’ UHD 120Hz signal. This 31.5″ addition to the Momentum series includes a T-shaped stand base with brushed dark silver plastic, whilst contrasting black plastic is found elsewhere. The top and side bezels are ‘dual-stage’, with a slim panel border flush with the rest of the screen plus a slender hard plastic outer part. The OSD (On Screen Display) is controlled by a joystick at the rear of the screen, towards the right side as viewed from the front.

A Momentum model

A 31.5″ IPS-type panel is used, with 3840 x 2160 ‘4K’ UHD resolution and support for a 144Hz refresh rate. We believe this to be the Innolux M315DCA-K7B AAS panel. Adaptive-Sync also features, including AMD FreeSync Premium with a 48 – 144Hz VRR range plus LFC. A light to very light matte antiglare screen surface is employed, whilst a 1000:1 static contrast, 178°/178° viewing angles and 10-bit (8-bit + FRC) colour support is included. The monitor includes a factory calibrated sRGB emulation setting with a specified DeltaE <2. A SmartUniformity mode is also included, a Uniformity Compensation (UC) setting designed to even out brightness at various points of the screen. A flicker-free WLED backlight provides a 500 cd/m² typical maximum luminance and 124% sRGB colour gamut. For some extra saturation and vibrancy and reasonable DCI-P3 coverage for HDR purposes.

Speaking of HDR, the monitor will respond to HDR10 content with VESA DisplayHDR 400 certification. So only a basic experience is offered, without the same brightness pulses, local dimming or colour gamut requirements as greater certification levels. It allows the reasonable colour gamut, brightness and 10-bit colour processing to be used. The panel we believe is used here can support a degree of local dimming with 16 zones, so that may be in play here. A 1ms grey to grey response time is specified (pinch of salt required) as well as a 1ms MPRT response time using the included strobe backlight mode. ‘Low Input Lag’ is also mentioned. The screen includes Ambiglow RGB LED lighting strips beneath the bottom bezel and at the rear, towards the top and sides. This system casts a field of light beneath and behind the monitor and is a relatively powerful system, allowing it to be used for ambience or to increase perceived contrast. The stand attaches centrally using a quick-release mechanism and can be removed to reveal 100 x 100mm VESA holes. The stand offers tilt, swivel and height adjustment (130mm or 5.12 inches). The ports face downwards and include; AC power input (internal power converter), DP 1.4, 3 HDMI 2.1 ports, a 3.5mm audio output, USB-C (65W PD, DP Alt Mode) and 4 USB 3.2 ports plus upstream. 2 of these USB ports are coloured yellow and support BC 1.2 fast charging. 2 x 5W DTS speakers are included for potentially fairly rich sound output, whilst 2-device PbP is supported.
