Gigabyte’s M27UA is a genuine 27-inch 4K gaming monitor launched in July 2024. It combines a 3840×2160 SuperSpeed IPS panel, a maximum 160Hz refresh rate, USB-C video, and Gigabyte’s claimed 128% sRGB and 95% DCI-P3 gamut figures. Those headline numbers need context: the “1ms” figure is MPRT rather than GtG, HDR is limited to entry-level DisplayHDR 400, and USB-C power delivery is only 18W.

That makes the M27UA potentially attractive as a sharp, fast mixed-use display, but not a substitute for an OLED or Mini LED HDR monitor, a professional reference display, or a high-power USB-C docking monitor.

What 27-inch 4K at 160Hz means

At 27 inches, 3840×2160 produces roughly 163 pixels per inch. Text, photographs and game geometry look considerably sharper than on a 27-inch 1440p screen. The trade-off is desktop scaling: Windows users will often find 125% or 150% scaling more comfortable than running the interface at 100%.

The 160Hz ceiling makes scrolling, camera movement and cursor motion smoother than 60Hz and gives a fast gaming PC more headroom than a 120Hz or 144Hz display. It does not guarantee 160 frames per second. Modern games at 4K can require upscaling, reduced settings or a high-end graphics card to approach that rate.

PlayStation 5 and Xbox Series X generally target up to 4K/120Hz, so the extra 40Hz is principally a PC-gaming advantage. The monitor still works well with consoles, but console owners should not pay a premium solely for the 160Hz specification.

SuperSpeed IPS, colour gamut and the 1ms claim

“SuperSpeed IPS” is Gigabyte’s product designation, not a new display category. The M27UA remains a conventional IPS-type LCD: it offers broad viewing angles and generally consistent colour across the screen, but its native contrast is much lower than VA, OLED or many Mini LED designs. IPS glow and backlight bleed can also vary between units.

Gigabyte claims 128% sRGB colour saturation and 95% DCI-P3. A gamut percentage describes the range of colours the panel can reproduce; it is not a colour-accuracy score. Wide-gamut mode can make unmanaged sRGB games and applications look oversaturated. An sRGB mode, operating-system colour management and an ICC profile measured from the exact unit can help, but the published gamut figures do not establish factory Delta E, white-point accuracy or panel uniformity.

The manual specifies 1.07 billion colours using 8-bit + FRC. That is not the same as a native 10-bit panel.

Likewise, “1ms response time” needs qualification. Gigabyte lists 1ms MPRT and 5ms GtG. MPRT is commonly associated with a strobing or motion-blur-reduction mode; it should not be read as every pixel transition completing in 1ms. The 5ms GtG figure is the more conventional specification.

HDR400 is entry-level HDR

The M27UA is certified for VESA DisplayHDR 400 and lists 400 cd/m² typical brightness. HDR-compatible games and video can use a wider signal range and higher highlights, but this is not premium HDR.

A typical 1000:1 IPS panel without meaningful local dimming cannot keep a bright object and a dark background independently controlled. Blacks therefore remain greyish compared with OLED, while Mini LED monitors with many dimming zones can produce stronger contrast and brighter highlights. HDR quality also depends on Windows or macOS settings, the game’s own HDR implementation and calibration.

Think of HDR400 as a useful compatibility feature, not a reason to expect OLED-like shadow detail or cinematic impact.

Ports, 4K/160Hz support and USB-C limitations

For a desktop PC, DisplayPort 1.4 with Display Stream Compression is the likely route to 4K/160Hz. The HDMI 2.1 inputs are useful for consoles and compatible PCs, but the label alone does not prove that the monitor exposes the full 48Gbps HDMI 2.1 bandwidth. USB-C carries DisplayPort Alt Mode, although the host laptop must support the required video mode.

USB-C power delivery is limited to 18W. That can provide light charging for a tablet, ultrabook or accessories, but it is far below the 65W–100W delivered by productivity monitors designed to replace a laptop charger. A performance notebook may continue discharging while gaming or rendering.

The three-port USB hub requires the monitor’s USB upstream connection to the computer. Retail listings advertise KVM functionality, but Gigabyte’s visible regional specifications do not document it consistently. Confirm the OSD menu, manual and firmware for your region before treating the M27UA as a KVM or docking solution. A monitor KVM normally switches USB peripherals between sources; it does not supply Ethernet, high-wattage charging or every feature of a dedicated dock.

Setting up the M27UA

  1. Connect a desktop PC by DisplayPort when targeting 4K/160Hz; use HDMI for a console or a source where HDMI is preferable.
  2. Use USB-C for a compatible laptop when one-cable video and modest charging are sufficient.
  3. Attach the USB upstream cable if you need the hub or Gigabyte’s OSD Sidekick software.
  4. In Windows or macOS display settings, select 3840×2160 and the highest available refresh rate.
  5. Enable Adaptive-Sync or the relevant variable-refresh option in the monitor and graphics-driver settings.
  6. Enable HDR only for supported games or video, then use the operating system and game calibration controls.

If 160Hz is missing

Check the cable rating, GPU driver, selected input, adapter or dock bandwidth, DSC support, and the laptop’s USB-C DisplayPort implementation. Also verify that the operating system has not reverted to 60Hz or a lower resolution.

If colours look too vivid

Try the monitor’s sRGB mode and colour-managed applications. Do not assume the mode is accurate without independent measurement; screenshots cannot show what another display is actually reproducing.

M27UA versus M27U and M27UP

The M27UA should be treated as its own model, not a renamed M27U. The earlier M27U has a related 27-inch 4K gaming concept, while the newer M27UP is listed by retailers as a separate 4K/180Hz model with dual-resolution features. Check the exact model number, port layout and panel specifications before comparing prices. A listing for an M27UP is not evidence that it is identical to the M27UA.

Availability and buying advice

Launch coverage dated July 2024 introduced the M27UA, but U.S. stock has since appeared inconsistent. The retrieved Newegg listing showed a $439.99 reference price while out of stock, and an open-box listing showed $395.99 with final-sale/non-refundable terms. B&H marked its page no longer available. These are historical availability signals, not guaranteed prices for September 2026; check Gigabyte’s retailer locator and live listings before ordering.

Because the model is older than many current 4K/180Hz, Mini LED and OLED displays, judge it by today’s street price rather than its launch positioning. An inexpensive, returnable new unit can make sense. An expensive open-box unit with no return rights is much harder to justify.

Who should buy it?

  • PC gamers: A good fit if you want 4K sharpness, high refresh and Adaptive-Sync, and your GPU can make use of them.
  • Console owners: Suitable for 4K/120Hz consoles, but 160Hz provides little additional benefit.
  • MacBook or Windows laptop users: USB-C video is convenient, but 18W charging is not a replacement for a laptop power adapter.
  • Mixed-use creators: 4K workspace and wide gamut are useful for general editing, photography and video work. Professional grading still calls for measured accuracy, uniformity and stronger HDR.
  • HDR enthusiasts: Look elsewhere if deep blacks, local dimming and bright highlights are priorities.
  • Budget buyers: Consider it when discounted well below newer 4K/180Hz alternatives, and compare warranty and return terms.

The M27UA’s strengths are its sharp 4K image, 160Hz PC refresh rate, broad connectivity and wide-gamut potential. Its compromises are modest contrast, entry-level HDR, the qualified response-time claim, weak USB-C charging and uncertain availability. It is sensible at the right price, but not automatically the best value simply because the box says “4K,” “160Hz” and “1ms.”
