Acer XR341CK 34-in 3440x1440 75Hz IPS FreeSync UltraWide Monitor Review
On-screen Display Features
The OSD on the Acer XR341CK includes quite a bit of functionality and getting around it with the buttons on the bottom of the monitor isn't too difficult. I still love the flexibility of the joystick method that ASUS uses on the ROG Swift line of products but what Acer has here is pretty standard for today's displays.
As with many monitors, the buttons are hidden under the bezel and you'll have to trust your eyes and your instincts to not accidentally hit the wrong switch and turn off the panel. You get quick access to volume, input, gamer presets and overdrive settings with your first press. The arrow on the far right opens up the rest of the options.
In the picture menu you can adjust brightness, contrast, black levels and enable blue light modes that help to remove blue from your screen to help with eye strain at the expensive of color accuracy. Imagine wearing Gunnar glasses without looking like a tool.
If you want precise control over the color output on your monitor, without going the route of calibration, the XR341CK has all the options you'll want including RGB and YMC hue adjustment.
Acer has included some other unique options like the ability to display the refresh rate in the upper corner of your monitor, acting something like an embedded FRAPS counter that changes as you game even in FreeSync modes. (It's refresh rate though, not frame rate.) Aim Point will put a static image in the center of your screen to help with FPS gaming and Game Mode offers a couple of different color presets for you to choose from.
The settings panel is where you can setup overdrive, set the DisplayPort input signal type, enable daisy chaining and walk through the various picture-in-picture and picture-by-picture modes.
Overdrive options include Off, Normal and Extreme. In our testing, for both NVIDIA and AMD configurations, Normal is the optimal setting. Interestingly, there is a big difference in how this monitor acts and performs with overdrive when its attached to a FreeSync-enabled system versus one that is NVIDIA-based or even AMD-based but without FreeSync support. It's an oddity and we haven't seen anything like it before - the behavior on the NVIDIA GPUs (and non-FreeSync AMD GPUs) in Extreme mode is horrible! Leaving it in Normal OD results in a high quality experience for all users though.
PiP and PbP setup is straight forward but much of the functionality seems lost without the monitor outputting a 1720x1440 EDID option to the systems they are connected to, allowing for a true side-by-side working environment. Instead, you seem to be limited to the 21:9 aspect ratio for both PiP and PbP, wasting much of the space on the panel.
Finally, here are the controls for the ambient light that glows from the bottom of panel. You can adjust the color, the style (flashing, breathing, etc.) and how bright the lights will be. Allowing the lights to stay on when the monitor goes to sleep is also up to you.
