AOC 4K Gaming Monitor is Back at a Minimum Price! It Offers Up to 320 Hz and Costs Less Than 6 Thousand CZK

When choosing a gaming monitor, people usually decide between a sharp image for work and the highest possible fluidity for fast-paced games. The AOC U27G4R offers both; you just need to switch between them. Plus, it’s incredibly cheap again: with code ALZADNY30, you can buy it on Alza for 5,990 CZK, which is 547 CZK cheaper than in the previous promotion. Its price has never been lower in history.

Quick summary:
✅ It makes sense if you want one monitor for both 4K work and fast-paced games, and you don’t want to spend more than 6 thousand CZK.
⚠️ Consider that only a powerful graphics card can handle a full 160 frames per second in 4K, and that HDR400 certification is the lowest level of HDR.
💡 For 5,990 CZK, you also get a stand with height adjustment and pivot, two HDMI 2.1 ports, and a four-port USB hub.

4K for Work, Full HD for E-sports

The main trick of the U27G4R is called Dual-Mode. The monitor normally runs at a native resolution of 3840 × 2160 pixels at 160 Hz, so on 27 inches, you get sharp text for work and a detailed image for story-driven games. After switching to Full HD (1920 × 1080), the refresh rate increases to 320 Hz, which competitive shooter players will especially appreciate. Full HD on such a large diagonal will naturally not be as sharp, but in a fast-paced game, you are usually more concerned with fluidity than sharpness.

According to Alza, the Fast IPS panel has a response time of 1 ms (GtG), and 0.5 ms (MPRT) in UHD mode. To combat screen tearing, there’s support for G-Sync Compatible, FreeSync Premium, and Adaptive-Sync, so the monitor works with both Nvidia and AMD graphics cards. You manage settings, including gaming modes, in the AOC G-Menu application.

Colors Promise a Lot, HDR is More on Paper

The seller states coverage of 124.7% sRGB and 95.9% DCI-P3 with an eight-bit color depth. These are declared values, not measurements by a calibrator, but it’s a decent foundation for games, movies, and home photo editing. The display surface is anti-reflective.

I would be more cautious with HDR. The monitor has VESA DisplayHDR 400 certification, which is the lowest level, and a brightness of 400 cd/m² with a contrast of 1,000:1 corresponds to a standard IPS panel. You can play HDR content, but don’t expect an effect like on a Mini-LED or OLED display. Those who want proper HDR must aim higher, for example, for the AOC U27G4XM 4K monitor with Mini-LED backlight.

A Stand That Means You Don’t Have to Buy an Arm

With cheaper monitors, the stand is often the first thing manufacturers save on. Not here. You can raise the screen within a range of 130 mm, tilt it, swivel it sideways, and thanks to the pivot function, you can even orient it vertically, which is useful for code or long documents. If you still wanted an arm, the monitor has VESA 100 × 100 mm mounting.

You connect it to a computer or console via two HDMI 2.1 and one DisplayPort 1.4; both HDMI and DisplayPort cables are included in the package. The built-in hub adds four USB-A 3.2 Gen 1 ports for a mouse, keyboard, or external drive, and there’s also a 3.5mm headphone jack. There is no USB-C among the ports, so you cannot connect a laptop with power delivery using a single cable.

Over a Thousand Units Sold and Almost All Five-Star Ratings

Customers give the monitor on Alza 4.9 out of 5 with 31 ratings, of which 29 are five-star and two are four-star. 100% of buyers recommend it, over 1,000 units have been sold, and the return rate is 0.67% according to Alza. The warranty is 36 months.

Who Benefits from the U27G4R for 5,990 CZK?

For 5,990 CZK with code ALZADNY30, I would go for it if you work and play on one monitor and have a graphics card that can actually handle high frame rates in 4K. With two HDMI 2.1 ports, it can also handle a console. However, it can also make sense with a less powerful graphics card, as less demanding e-sports games can utilize the high refresh rate in Full HD mode even without the most expensive card.

Conversely, if you are buying primarily for HDR movies, it’s worth paying extra for Mini-LED. And if you want to connect a laptop to the monitor with a single USB-C cable, you’ll need a different model. For everyone else, this is currently the lowest price at which the U27G4R has been sold.

Do you prefer gaming in sharp 4K, or do you prioritize the highest possible frame rate?
