The OLED panel on the Gigabyte AORUS FO48U OLED is 48 inches wide. It has a wide viewing angle and, like all displays with OLED panels, has deep, black blacks that don’t fade around bright objects. It’s a lot like the LG 48 C1 OLED, but it has more traditional monitor-style connections like a DisplayPort port, a built-in USB hub, and a keyboard-video-mouse (KVM) switch. It has a response time that is almost instantaneous, so you can see clear motion behind fast-moving objects.
It also has a low input lag and works with both FreeSync and G-SYNC. Unfortunately, it’s not very bright, and the automatic static brightness limiter (ASBL), which makes the screen dim after a few minutes of inactivity, makes it hard to use on a desktop. When typing or reading a web page with a lot of text, this can be a problem because the screen doesn’t change enough to set off the timer.

Gigabyte Aorus FO48U review: Design and Features

Even though it’s made to work more like a computer monitor than a TV, which we will explain in a moment, it has the shape and design of a small TV. Instead of a stand, it has two feet that don’t move and can’t be adjusted in any way. It doesn’t have buttons. Instead, it has a remote and a single joystick that you probably won’t ever touch.
Its size is similar to that of a TV, so it has room for big speakers that sound better than any PC gaming monitor should. It’s hard to use a monitor this size at a desk, which is why the product page doesn’t have a single picture of it being used that way. If you want to use this monitor on your desk, don’t let the advertising stop you. You can buy this gaming monitor from its official website.
Gigabyte Aorus FO48U review: Display and Performance
The inputs and outputs are on the left side of the monitor. You get two HDMI 2.1 ports, a DisplayPort 1.4 with Display Stream Compression for full HDR and refresh rate support, one USB Type-B upstream connection, two USB 3.0 ports, a USB Type-C with 5V/1.5A fast charging support, a headphone jack, and a line-out for speakers.
Players of consoles should be aware that the HDMI ports can only handle 24 Gbps, not the full 48 Gbps that you would expect from a modern HDMI 2.1 port. It’s a strange choice, and because there isn’t enough bandwidth, your console will have to use compressed HDR (4:2:0), which won’t look as good as a full-speed port.
Gigabyte Aorus FO48U review: Picture Quality

The OSD on the Gigabyte Aorus FO48U is the same as the one on all Aorus monitors. It has six sub-menus, eight picture modes, and three user-defined memories. You can use the joystick on the panel, a hand-held remote, or the OSD Sidekick app from Gigabyte to control it. When an HDR10 signal is found, there are four more picture modes that can be used.
In the Gaming menu, you can turn on or off Adaptive-Sync and Aim Stabilizer, which is Aorus’ version of a backlight strobe that reduces blur. You can’t use both at the same time. You must instead turn off Adaptive-Sync before you can use Aim Stabilizer.
Gigabyte Aorus FO48U review: Gaming
When you click the joystick once and move it to the left or right, the Aorus gaming aids and Dashboard come on. There is a crosshair, a timer, and a framerate counter. You get one green reticle, and the OSD Sidekick app lets you make up to three more. The Dashboard connects to your PC through a USB cable and lets you check the CPU and GPU temperatures, fan speeds, usage rates, framerate, and mouse CPI.
Final Words
The Gigabyte AORUS FO48U is a great monitor for gaming. The OLED panel has a response time that is almost instantaneous. This means that motion is clear and there is no blur behind fast-moving objects.
