KOORUI G3221SC 31.5-Inch 170Hz 2K QHD 1500R VA Curved Gaming Monitor — Complete Technical Overview
The KOORUI G3221SC is an expansive 31.5-inch (80.0 cm diagonal, 32-inch class) high-refresh 2K Quad HD (2560 × 1440) curved gaming and multimedia monitor engineered by KOORUI (a display brand established by HKC Corporation). Designed for immersive AAA single-player adventures, competitive PC and console gaming, sim-racing rigs, and multi-window desktop productivity in Bangladesh, the G3221SC combines a wrap-around 1500R (R1500) curved VA (Vertical Alignment) panel with a rapid 170Hz maximum refresh rate, 1ms response time (rated at 1ms GtG across Bangladesh retailer specifications and product gallery badges, with 1ms MPRT / 4ms GtG cited in regional KOORUI documentation), deep 3000:1 static contrast, 300 cd/m² brightness, wide 100% sRGB and 90% DCI-P3 color coverage, and HDR10 high dynamic range support.
Across its large 31.5-inch 16:9 viewing surface, the native 2560 × 1440 (2K QHD) resolution delivers approximately 93 PPI (~93.24 pixels per inch) and a ~0.2724 mm pixel pitch—matching the exact pixel sharpness of a standard 24-inch 1080p monitor while providing 77 percent more screen real estate (3.68 million pixels versus 2.07 million pixels on Full HD). Unlike 31.5-inch 1080p monitors (~70 PPI) where individual pixel grids look coarse at normal desk seating distances, the KOORUI G3221SC keeps UI text, game HUD elements, spreadsheets, and distant battlefield targets crisp and well-defined.
Immersive 1500R (R1500) Curvature & 31.5-Inch QHD (2560 × 1440) VA Panel Architecture
On a large 31.5-inch display positioned at a standard desktop viewing distance of 60 cm to 80 cm, flat panels force your eyes to refocus as you scan from the center crosshair toward the far left and right edges, and can introduce off-axis VA gamma shift at the corners. As illustrated in the product gallery's curvature comparison graphic, the KOORUI G3221SC solves this with an ergonomic 1500R curvature radius (corresponding to a circle of 1,500 mm radius):
- Conforms Naturally to the Human Field of View: Compared with flatter 1800R or uncurved panels, the tighter 1500R arc brings the left and right edges closer to an equidistant focal plane relative to the viewer's eyes, minimizing peripheral eye-fatigue zones and enhancing depth perception in flight simulators, racing titles, and open-world RPGs.
- 2K QHD (2560 × 1440) vs. 720p/1080p Clarity: As highlighted in the gallery's split-screen 1440p comparison visual, rendering 3,686,400 discrete pixels across the 16:9 widescreen panel eliminates jagged stair-stepping on fine mechanical textures, spacecraft hulls, and distant foliage while allowing comfortable side-by-side window snapping for coding, streaming, and content creation.
- Wide 178° / 178° Viewing Angles & 3-Sided Frameless Bezel Design: Vertical Alignment liquid crystal architecture preserves consistent 178° horizontal and 178° vertical viewing angles, while the ultra-slim 3-sided micro-bezel frame maximizes screen-to-body ratio and enables seamless dual- or triple-monitor curved cockpit setups.
3000:1 High Static Contrast, 90% DCI-P3 / 100% sRGB Color Gamut & HDR10 Visuals
One of the defining advantages of the KOORUI G3221SC's VA panel over conventional IPS gaming monitors (which typically cap out at 1000:1 static contrast) is its ability to block backlight bleed in dark scenes and render deep, inky blacks:
- 3000:1 Static Contrast Ratio (Up to 3500:1 in Select Regional Listings): As shown on the official Vivid Color Gamut product graphic and verified across Bangladesh retailer specification tables (Star Tech, Techland BD, UltraTech, Skyland, PC House), the G3221SC delivers a 3000:1 typical static contrast ratio alongside a 20,000,000:1 dynamic contrast ratio (DCR). Select regional KOORUI listings (such as KOORUI Korea ko.koorui.net) also cite up to 3500:1 static contrast depending on panel batch. This 3× higher contrast floor reveals subtle shadow detail in dark dungeon corridors, night-time tactical maps, and sci-fi space scenes without grayish IPS glow.
- 300 cd/m² Brightness & HDR10 Decoding: The LED backlight is rated at 300 cd/m² (nits) typical brightness on the product's official color-gamut infographic and Bangladesh retail datasheets (with 250 cd/m² minimum/typical cited on select regional pages such as KOORUI Pakistan koorui.com.pk). Combined with HDR10 signal support, the display expands highlight-to-shadow tonal separation in HDR-compatible PC and console titles.
- 90% DCI-P3 & 100% sRGB Wide Color Volume: Covering 100% of the sRGB color space and 90% of the cinema-grade DCI-P3 gamut with 16.7 million colors (8-bit color depth), the G3221SC produces vibrant primary colors, rich skin tones, and smooth sky gradients for gaming, YouTube/Netflix streaming, and everyday photo or video editing.
170Hz High Refresh Rate, 1ms Response Time Disambiguation & FreeSync / G-Sync Compatibility
Built for responsive high-frame-rate gameplay, the KOORUI G3221SC pairs its QHD resolution with fast refresh cycling and variable refresh rate (VRR) synchronization while transparently reconciling specification terminology across sources:
- Up to 170Hz Refresh Rate via DisplayPort (Up to 144Hz via HDMI 2.0): Connecting a desktop gaming PC over the DisplayPort input unlocks the full 170Hz refresh rate at native 2560 × 1440 resolution—updating frames every 5.88 milliseconds (nearly 3× faster than a 60Hz monitor). When connected over either of the two HDMI 2.0 ports, standard HDMI 2.0 TMDS bandwidth supports 2560 × 1440 at up to 144Hz on PC and 1440p at 120Hz on PlayStation 5 and Xbox Series X/S consoles.
- Response Time Disambiguation (1ms GtG vs. 1ms MPRT): The primary product badge (image-1.webp) and Bangladesh retail specification sheets list 1ms (GtG) response time, whereas regional KOORUI datasheets (koorui.com.pk, ko.koorui.net, and user manual tables) specify 1ms MPRT (Moving Picture Response Time) using backlight strobing alongside overdrive-assisted gray-to-gray transitions (typically 1ms MPRT / 4ms GtG on curved VA panels). Engaging the monitor's OSD overdrive and MPRT settings sharpens fast camera pans in FPS, battle-royale, and esports titles.
- AMD FreeSync & NVIDIA G-Sync Compatible Adaptive-Sync: Variable refresh rate support dynamically locks the monitor's refresh rate to the real-time frame output of AMD Radeon GPUs (via FreeSync over HDMI or DisplayPort) and NVIDIA GeForce GPUs (via G-Sync Compatible Adaptive-Sync over DisplayPort), eliminating horizontal screen tearing and frame-pacing stutter.
Connectivity, DisplayPort 1.4 vs. 1.2 Source Resolution & Multi-Platform Console Support
As depicted in the rear I/O diagrams in image-5.webp and image-6.webp, the KOORUI G3221SC provides dedicated digital video and audio interfaces for multi-device setups:
- 2× HDMI 2.0 Inputs: Connect up to two HDMI sources simultaneously—such as a gaming laptop, PlayStation 5, Xbox Series X/S, or Nintendo Switch—without swapping cables. Supports up to 2560 × 1440 @ 144Hz for PCs and 1440p @ 120Hz for current-gen consoles.
- 1× DisplayPort Input (DP 1.4 vs. DP 1.2 Specification Reconciliation): Bangladesh retailer specification tables (Star Tech, Techland BD, UltraTech, Skyland, PC House) and KOORUI Korea (ko.koorui.net) specify 1× DisplayPort 1.4, whereas the manufacturer's rear port diagram in image-6.webp and KOORUI Pakistan (koorui.com.pk) label the interface as DP 1.2. In practical use, both DisplayPort 1.2 HBR2 (17.28 Gbps data rate) and DisplayPort 1.4 easily carry uncompressed 2560 × 1440 at 170Hz (8-bit RGB) with Adaptive-Sync enabled.
- 1× 3.5mm Audio Out Jack & DC Power Input: Because the KOORUI G3221SC does not include built-in internal speakers (Speaker: N/A), it provides a rear 3.5mm stereo audio-out jack to pass digital audio from HDMI or DisplayPort directly to wired headphones or external desktop speakers, alongside the barrel DC power input (rated at 57W power consumption).
Ergonomic Tilt Reconciliation, VESA 100 × 100 mm Mounting & Physical Build
The matte-black chassis of the KOORUI G3221SC is supported by a wide V-wing desktop stand with a crimson-red top accent on the upright column and an integrated lower cable-routing window:
- Tilt Angle Reconciliation (-5° to +15° vs. -5° to +20°): The included stand supports forward and backward tilt adjustment. Note that while the catalog baseline and Bangladesh retail spec tables list -5° to +15° tilt, the official manufacturer schematic in image-6.webp and user manual diagrams specify -5° to +20° tilt. The stand does not include height, swivel, or portrait pivot adjustment out of the box.
- VESA 100 × 100 mm Wall & Monitor Arm Compatibility: As clearly called out in both image-5.webp and image-6.webp, removing the quick-release stand neck reveals a standard 100 × 100 mm VESA mounting pattern, allowing you to attach the 31.5-inch curved screen to a heavy-duty gas-spring monitor arm or wall bracket for full height, swivel, and articulation control.
- Dimensions, Weight & Rear OSD Controls: The monitor weighs 8.33 kg (18.36 lbs) (with approximately 5.55 kg net / 7.95–8.33 kg gross cited across regional shipping tables) and measures approximately 711 × 526 × 251 mm with the stand (or 711 × 423 × 106 mm without the stand). Five tactile physical OSD buttons on the rear-right panel give quick access to Game Mode presets, crosshair overlays, timer functions, Black Stabilization, Flicker-Free DC dimming, and Low Blue Light eye-care filters.
Bangladesh Buying Guide & Warranty Verification
In Bangladesh, the KOORUI G3221SC 31.5" 170Hz 2K QHD VA Curved Gaming Monitor carries a catalog MSRP of BDT 38,500 (with live retail promotional pricing across local stores such as Star Tech, Techland BD, UltraTech, Skyland, and PC House typically ranging between BDT 26,300 and BDT 38,500 depending on stock and campaign offers). While leading Bangladesh computer retailers advertise a 3-Year Warranty, regional international stores (such as KOORUI Pakistan) list differing 1- to 2-year regional warranty terms. Because warranty duration, dead-pixel thresholds, and bundled cables (DisplayPort vs. HDMI) are governed by the selling retailer and authorized local distributor in Bangladesh, buyers should verify exact warranty terms and included accessories on their purchase invoice.
