The Samsung Q80C looks simple but functional. It has a clean hexagonal stand, thin bezels, and a clean-looking design. It looks nice enough to fit in any room without being distracting.

Design
The center-mounted stand is small, so the TV doesn't require a large desk or media center. There's some side-to-side wobbling and a fair amount of front-to-back wobbling. It's not concerning if you don't move the TV around, but it's certainly more wobble than on premium models. The stand lifts the screen 3.12" above the surface of your table, so almost every soundbar fits in front of it without blocking the screen.
Footprint of the 65-inch stand: 15.38" x 11.25".

The back panel is made of textured plastic with vertical etched lines. There are grooves in the casing to help with cable management, which then get funneled into the stand. The stand has a removable cover that helps with hiding cables. The inputs are recessed and are hard to access if the TV is wall-mounted.

Contrast
Native Contrast
The TV has adequate contrast. It's a solid improvement over the Samsung Q80B QLED, helped by having double the local dimming zones of its predecessor. Still, blacks look gray in the dark, and overall, this TV's contrast doesn't impress in a dark room. If you want something in a higher tier with much better contrast, check out the Samsung QN85C/QN85CD QLED or the newer Samsung QN85D/QN85DD QLED.

While the Samsung Q80C QLED has more dimming zones than the Samsung Q80B QLED, it's still insufficient to provide a truly satisfactory dimming experience. As a result, bright highlights show significant blooming in dark scenes, and it's distracting when watching.

Dimming Zones Count Of Tested TV
The lighting zone transitions on the Samsung Q80C are mediocre. On big bright objects, there's massive blooming when the object is in multiple zones at once. For smaller objects, there are noticeable brightness fluctuations both on the object and in its blooming as the object moves from zone to zone.
—
6.0 Picture Quality
The contrast and dark details in Game Mode are similar to those outside but with some differences. The dimming is less aggressive in Game Mode; this results in less aggressive blooming as it spreads out over fewer zones. There are also fewer flickering or brightness fluctuations as bright objects move from zone to zone, as the dimming is slower to react when compared to the 'Movie' mode. Unfortunately, this comes with the caveat that the perceived contrast isn't as high in Game Mode as in 'Movie' mode due to the slower, less aggressive local dimming.

The TV has satisfactory HDR peak brightness. Interestingly, it's slightly dimmer in real content than the Samsung Q80B QLED. Ultimately, while satisfactory, the Samsung Q80C doesn't get bright enough to get the full HDR experience.
These measurements are after calibrating the HDR white point with the following settings:
- HDR Picture Mode: Movie
- Brightness: 50 (Max)
- Contrast: 50 (Max)
- Color Tone: Warm2
- HDR Tone Mapping: Static
- Local Dimming: High
- Color Space Settings: Auto
While we tested with HDR Tone Mapping set to 'Static' as it's more accurate, setting it to 'Active' makes the image brighter in some scenes, as you can see with the results below:
- Hallway Lights: 456.6 cd/m²
- Yellow Skyscraper: 438.5 cd/m²
- Landscape Pool: 147.5 cd/m²

The Samsung Q80C has very good PQ EOTF tracking. It's overbrightened through the entire range, but it never gets excessive. When the TV is near its peak brightness, the panel hard clips, resulting in clipping and a potential loss of detail in very bright scenes, but inversely it also lets the TV display bright highlights to the best of its capacity.

The Samsung Q80C has a very good HDR color gamut. It has fantastic coverage of the commonly used DCI-P3 color space, so the vast majority of HDR content looks vibrant and pleasant to the eyes. The panel's colors are slightly off; greens are too yellow, yellows and magenta are too red, and blues are too purple. The deviations are slight but widespread.

Sadly, this TV has bad black uniformity. Without local dimming enabled, the screen fills with a cloud-like blue color, with almost no black in sight. It looks much better with local dimming enabled, but there's significant blooming around bright elements, which again looks like a cloud of blue around the highlight. Note that you can't disable local dimming without going into the service menu, which requires using an older Samsung remote.
