But is it really better than traditional OLED models like the LG C-series?
And is it worth choosing over Mini-LED alternatives?
In this detailed Samsung S90C OLED review, we break down real-world performance — from brightness and color to gaming, sports, and overall value.
Design & Build Quality
The S90C keeps Samsung’s clean, modern aesthetic:

QD-OLED Technology Explained
Unlike traditional OLED, QD-OLED combines:
-
Self-lit OLED pixels
-
Quantum Dot color layer
This results in:
-
Higher brightness than standard OLED
-
More vibrant color volume
-
Better highlight intensity
Black Levels & Contrast
Because it’s OLED-based:
-
Blacks are truly black
-
No blooming
-
Infinite contrast
Dark scenes look clean and cinematic.
In comparison to Mini-LED, it delivers deeper shadow detail with zero halo effects.
Brightness Performance
One of the biggest strengths in this Samsung S90C OLED review is brightness.
Compared to traditional OLED:
-
Higher peak HDR brightness
-
Stronger specular highlights
-
Better performance in moderately bright rooms
It still won’t match the absolute brightness of top Mini-LED TVs, but for an OLED, it’s impressive.
Color Performance
QD-OLED enhances color vibrancy significantly.
You get:
-
Richer reds
-
Brighter greens
-
Stronger HDR color highlights
-
Excellent color volume
Skin tones remain natural while highlights pop more than conventional OLED panels.
HDR Performance
