You’ve painstakingly perfected every detail of your gaming setup, from gear to lighting. But finicky monitor brightness settings can still interrupt your immersive experience. Serious gamers know the frustration of a sudden content shift that flattens the image and jolts you back to reality.
This happens because HDR settings often force OLED defaults that aren’t always ideal. When the content shifts, the display automatically compensates, whether you want it to or not. Creative professionals are often constrained by standard HDR brightness limitations. When you’re editing a high-contrast image or grading footage with a wide dynamic range, a display that makes its own brightness decisions can throw off your judgment in ways that are hard to catch.
For most of OLED’s history as a display technology, that’s just been the deal. But the MPG 341CQR QD-OLED X36 from MSI is among the first monitors to allow for granular fine-tuning of brightness parameters through a feature called Uniform Luminance.
MPG 341CQR QD-OLED X36
Ultra-immersive UWQHD resolution with a blazing fast 360Hz refresh rate
Uniform Luminance is one of a larger set of calibration tools on the X36, including six-axis color adjustment and automatic game-specific profiles, that give serious users the level of precision and control they’ve always wanted.

What Is MSI Uniform Luminance?
The hardware specs behind the X36 are impressive: This 34-inch ultrawide is built around a QD-OLED panel, a display type that layers quantum dot film over an organic LED array to push both color volume and peak brightness past what either technology is capable of solo.
What sets this generation apart, though, is on the software side. MSI’s Uniform Luminance gives users direct control over how the panel manages brightness as the on-screen image changes. The underlying variable is called Average Picture Level (APL), which is a measure of how much of the screen is bright or white at any given moment.
On most OLED displays, as APL rises, the panel naturally rolls back peak output to stay within power limits. (This is what causes that dimming effect during high-contrast gaming scenes, or, for creatives, when switching between a dark editing interface and a bright image open in Lightroom or Photoshop.)
But with Uniform Luminance, you decide how aggressively that rolloff happens. The feature offers 14 individual adjustment points spanning APL values from 3% to 75%.

Customizing the HDR Curve
To get started customizing, open the OSD Menu and navigate to Gaming Features > DisplayHDR. From there, select either Cust (True Black 500) for darker viewing environments or Cust (Peak 1300) for brighter ones. Both modes give you the same 14-point brightness curve to work with.
Use the five-way joystick, located beneath the screen, to move along the curve and adjust each point. Most users will land on one of three approaches:

-
Peak brightness at 3% APL with a gradual rolloff, which maximizes contrast but will show dimming as brighter scenes take over more of the screen
-
A gentler slope that keeps brightness more stable across mixed content, at the cost of some peak contrast
-
A near-flat curve that holds brightness steady regardless of what’s on screen—the most comfortable option for long sessions
To reset, go to OSD Menu > General > Reset All (though keep in mind this will clear all your settings, not just the brightness curve).

SDR Excellence: Gamma and Six-Axis
Most gaming monitors give you three color channels to work with: red, green, and blue (RGB). The X36 adds cyan, magenta, and yellow to the mix, bringing the total to six axes of adjustment.
For gamers, this results in more vivid, true-to-life colors across visual elements like skin tones and lighting effects. For anyone doing color-sensitive work like photo editing or video grading, it can be the difference between a “close enough” color profile and a client-wowing final product.
In SDR mode, gamma adjustment is also available, with selectable preset curves to suit different use cases. Dialing in the right gamma curve shapes how the display renders grayscale transitions and determines whether a stormy sky or the shadow side of a subject’s face looks dimensioned or flat.
Both six-axis color and gamma adjustment are restricted to SDR mode and won’t apply when HDR is active. (For HDR brightness control, that’s where Uniform Luminance comes into play.)
The Intelligent Edge
Different games make very unique demands of your display’s capabilities. A dark, atmospheric horror title calls for settings that prioritize shadow detail; an open-world game with sweeping vistas might benefit from a flatter, more stable luminance curve; a fast-paced competitive title has different priorities still. But manually cycling through OSD settings every time you switch games is annoying.
MSI’s Gaming Intelligence AI Menu removes that step. The feature lets you link your Uniform Luminance, brightness, and color settings to specific game titles, so when a recognized title launches, the display loads its corresponding profile automatically.
Specs at a Glance
Display customization at this depth has historically been the domain of professional-grade hardware with eye-popping price tags. The X36 brings it to a 34-inch ultrawide built to slide into the gaming or office rig you already have at home.

Why was my monitor’s brightness locked in HDR mode?
HDR standards govern brightness and color temperature to maintain display accuracy across certified content. Most manufacturers leave those parameters inaccessible once HDR is active. MSI has opened them up on the X36 while keeping adjustments within the panel’s power limits.
Can I push brightness above the factory curve?
No. The factory curve is the ceiling; it reflects what the panel can physically sustain. All custom adjustments go downward from there.
What is Average Picture Level (APL)?
Average Picture Level is the percentage of the screen that’s bright or white at any given moment. A low APL scene is mostly dark with a small bright element; a high APL scene is predominantly bright. The panel scales its peak brightness based on this figure to manage power and heat.
How many adjustment points does the brightness curve offer?
The X36 has 14 adjustment points, spanning APL values from 3 to 75%.
