AOC AGON PRO AG326UD 31.5-inch 4K UHD 165Hz QD-OLED Gaming Monitor

AOC AGON PRO AG326UD 31.5-inch 4K UHD 165Hz QD-OLED monitor combines a 3840 x 2160 panel, HDR True Black 400, HDMI 2.1, a USB hub and built-in speakers. AOC manufacturer specifications are used where Bangladesh retailer pages conflict.

Product overview

The AOC AGON PRO AG326UD is a 31.5-inch flat 4K UHD gaming monitor built around a QD-OLED panel. Its native 3840 x 2160 resolution, 16:9 ratio and 165Hz maximum refresh rate target users who want detailed PC gaming alongside a large, color-rich screen for films and creative work. The product also includes adaptive sync, two HDMI 2.1 inputs, a DisplayPort 1.4 input, a USB hub and built-in speakers. It is model AG326UD in the AGON PRO line. The monitor’s marketing emphasizes 4K detail, QD-OLED contrast and a VESA DisplayHDR True Black 400 certification. The display is flat rather than curved, and its stand supports height, tilt, swivel and pivot adjustment.

QD-OLED panel and 4K detail

AOC specifies a 31.5-inch QD-OLED panel with 3840 x 2160 UHD resolution. At this diagonal and resolution, the display provides approximately 139.87 pixels per inch, with a listed pixel pitch of 0.1814mm. QD-OLED combines OLED pixel-level light control with quantum-dot color conversion; black-level appearance and contrast differ from a conventional backlit LCD. AOC lists a static contrast ratio of 1.5 million to one and a dynamic ratio of 80 million to one. The actual viewing experience depends on source material, brightness, color mode and room lighting. UHD gives more pixel detail than QHD at the same physical size, but the graphics system must render and transmit the higher resolution at the selected refresh rate.

Refresh rate, response and variable refresh

AOC lists a maximum refresh rate of 165Hz and a 0.03ms gray-to-gray response-time specification. A Star Tech summary calls out 0.05ms MPRT; MPRT and GtG describe different measurement methods and should not be compared as if they were the same test. AOC also lists Adaptive Sync and NVIDIA G-SYNC Compatible support, with an indicated 48–165Hz sync range. Variable refresh can help reduce tearing when the graphics source, driver, cable and selected display mode support it. A 165Hz monitor does not make a game render at 165 frames per second by itself; performance depends on the GPU, game settings and workload. Verify the selected HDMI or DisplayPort path supports the intended 4K refresh and color settings.

HDR and brightness

AOC identifies VESA Certified DisplayHDR True Black 400 support and lists a 1000 cd/m² brightness specification on its model page. The local retailer specification breaks this into 250 cd/m² SDR, 450 cd/m² at HDR APL 10% and 1000 cd/m² at HDR APL 3%; those are different test conditions, and the peak figure should not be read as full-screen sustained output. HDR results also depend on the content, operating system, GPU, connection and monitor settings. OLED’s pixel-level dimming can produce deep dark scenes, while bright highlights are limited by the panel’s power and thermal behavior. For a reliable comparison, check the HDR certification and use the brightness measurements only with their stated APL/test conditions.

Color reproduction and viewing

AOC lists 1.073 billion colors at 10-bit, 100% sRGB (CIE 1931), 99% DCI-P3 and 97.5% Adobe RGB in its detailed product specification. It also lists Delta E below 2 for sRGB. These values describe the model’s stated color capabilities; gamut coverage and gamut volume use different measurement definitions, and a manufacturer claim is not a substitute for an independent calibration report. The screen is flat, has a 16:9 aspect ratio and 178-degree horizontal and vertical viewing angles. AOC specifies an anti-reflection panel treatment and 2H display hardness. For color-critical work, use a calibrated workflow and confirm that the selected picture mode and application are color managed.

Inputs, USB hub and audio

The official AOC model specification lists two HDMI 2.1 inputs, one DisplayPort 1.4 input, three USB-A downstream ports operating at 5Gbps, one USB-B upstream port and a 3.5mm headphone output. The USB-B upstream connection links the monitor hub to the computer; connect it when using the monitor’s downstream USB ports. AOC also lists built-in speakers rated at 8W x 2. Bangladesh retailer copy conflicts with the official port list: Star Tech’s feature summary says two HDMI 2.0 and two DisplayPort, but AOC specifies HDMI 2.1 x 2 and DisplayPort 1.4 x 1. Manufacturer documentation is treated as authoritative. Confirm the required cable and timing for the host device before purchase.

Gaming and display features

The AG326UD supports Adaptive Sync and NVIDIA G-SYNC Compatible operation as listed by AOC. AOC also describes a gaming-oriented stand with a compact base and cable management, RGB Light FX, a USB hub, an OSD, and AOC G-Menu software for settings customization. It has a VESA DisplayHDR True Black 400 certification and supports UHD at up to 165Hz. These features support a desktop gaming setup, but their simultaneous availability can depend on input, refresh mode, firmware, HDR mode and graphics driver. AOC G-Menu is a PC utility rather than a requirement for basic monitor operation. Users can also configure input, image and power behavior using the monitor’s on-screen display controls.

OLED care and burn-in warranty

AOC describes the AG326UD as an OLED product that requires regular screen maintenance to reduce image-retention risk. Its manual explains screen maintenance and recommends following the on-screen care prompts. The AOC US product page lists a three-year warranty including OLED burn-in coverage, with the condition that screen maintenance is performed according to AOC instructions. Warranty rights and the claim process depend on the sales region and distributor. Bangladesh retailers advertise a three-year warranty, but the exact local provider, proof requirements and burn-in claim conditions should be confirmed in writing. OLED care features can reduce risk but cannot guarantee that image retention is impossible, especially with prolonged static content.

Ergonomics and mounting

The AOC specification lists tilt from -5 to +25 degrees, swivel from -15 to +15 degrees, height adjustment up to 150mm and pivot capability. It supports a 100 x 100mm VESA wall mount and includes a Kensington lock slot. The screen weighs approximately 10.23kg with its stand and 7.4kg without; verify the rated capacity of any monitor arm or wall mount. The height range is 485.9 to 635.9mm with the base under the published AOC dimensions. Use the monitor’s stand adjustments to align the large 31.5-inch screen with eye level and viewing distance. Mounting hardware requirements and what comes in the regional box can vary by country.

Dimensions and installation space

AOC lists dimensions with base at 717.3 x (485.9–635.9) x 316.8mm (W x H x D), and without base at 717.3 x 420.8 x 106.5mm. The listed package dimensions are 900 x 507 x 188mm, with gross package weight of 13.39kg. Measure both the desk footprint and vertical clearance before installing the stand or arm. A 31.5-inch monitor can occupy a significant portion of a shallow desk; leave space for a keyboard, peripherals and ventilation. These manufacturer dimensions are for the model and packaging specification; the exact contents and packaging can vary by sales region. The catalog keeps carton dimensions in the specifications and does not infer shipping measurements from a retailer’s different unit order.

Power and operating details

AOC lists an internal power supply, 123W typical consumption, 0.5W standby and 0.3W off-mode consumption. The quick-start guide specifies 100–240V AC at 50/60Hz and 2.5A input. These are product ratings, not a prediction of an individual electricity bill; actual draw depends on brightness, HDR use, connected USB devices and the selected picture mode. Use the supplied power cable and a grounded outlet. AOC’s page also lists Energy Class G. If the monitor is used for long sessions, enable the manufacturer’s OLED maintenance guidance and avoid interrupting a screen-care cycle unless the manual says it is safe to do so.

Accessories and package

AOC’s quick-start guide says the package can include monitor, stand, base, wall-mount bracket, quick-start guide, warranty card, screwdriver, wall-mount screws, stand screws, power cable, HDMI cable, DisplayPort cable, USB cable and audio cable. The guide notes that the supplied contents differ by country or region and that the product’s appearance may vary from illustrations. The catalog does not guarantee every cable is present in a Bangladesh retail box; confirm the sealed-box contents with the seller. This matters when a buyer plans to use a specific high-bandwidth connection or the USB hub on day one. The included stand is removable if the monitor will be VESA mounted.

Bangladesh pricing and warranty check

When reviewed, Star Tech displayed ৳176,000, a prior ৳177,000 cash figure and a regular price of ৳190,960, with the page marked in stock. Ryans showed ৳176,000 special price and ৳190,960 regular price, with delivery listed in one day. These are retailer page observations, not a guaranteed current offer or BiponiBD quote. The existing catalog MSRP of ৳176,000 matches the displayed special amount and is preserved. AOC’s global page lists three years including burn-in under the manufacturer maintenance instructions; Star Tech also advertises three years. Confirm the local distributor, current stock, final checkout amount, warranty service location and OLED burn-in terms before ordering.

Advantages and trade-offs

The AG326UD combines 4K detail, a 165Hz ceiling, QD-OLED contrast and a broad connection set in a flat 31.5-inch display. It includes speakers, USB hub ports, pivot-capable ergonomics and a three-year global OLED warranty statement. The 4K 165Hz combination requires a capable GPU and appropriate cable. The 31.5-inch size and 10.23kg stand-equipped weight need sufficient desk space or a rated arm. OLED maintenance remains relevant for users who display static desktop elements for long periods. Bangladesh seller descriptions contain inconsistent port and response-time claims, so exact-model AOC specifications should guide expectations. Buyers should compare image quality, power use and local service terms against other QD-OLED displays before deciding.

Who should consider this monitor

This monitor suits PC gamers who want a 4K image with refresh rates above standard office displays, as well as users who value OLED contrast, broad color and built-in audio. It may also suit creative users who work in a standard-gamut or DCI-P3 workflow and want high pixel density. It is less suited to buyers with a small desk, low-power graphics hardware, a need for USB-C laptop docking, or a requirement for burn-in-free static-screen use. Before purchasing, verify the PC’s 4K 165Hz output, intended cable, USB-B upstream connection, VESA or stand fit, regional warranty and package contents. The stand’s pivot is listed, but portrait use of a large panel should be planned for desk and cable clearance.
