4K gaming support
LG C6
5.0
Console gaming at 4K/120 and PC gaming up to 4K/165 are both handled smoothly, with strong HDR and responsive controls.

Dolby Atmos support
LG C6
3.0
Atmos decoding is included, but standard models lack the height and scale needed for truly immersive effects. A soundbar remains the best route to cinematic audio.
LG StanByMe 2No score yet
Dolby Vision support
LG C6
5.0
Dolby Vision content looks vibrant, accurate, and cinematic, making it the preferred premium HDR format on the C6.

EARC support
LG C6No score yet
LG StanByMe 2
3.0
eARC gives the StanByMe 2 a straightforward path to better external sound. The practical tradeoff is that a wired soundbar connection undermines the product’s otherwise portable setup.
FreeSync support
LG C6
5.0
AMD FreeSync Premium works as part of a comprehensive VRR package, supporting smooth PC and console play.

HDMI 2.1 support
LG C6
5.0
The HDMI 2.1 implementation is unusually complete, with full-bandwidth gaming features available across all four inputs.
LG StanByMe 2No score yet
HDR10+ support
LG C6
1.3
HDR10+ remains unsupported, which limits format flexibility for some streaming and gaming content despite otherwise strong HDR capabilities.
LG StanByMe 2No score yet
HDR format support
LG C6
3.0
Dolby Vision, HDR10, and HLG are supported, but the continued absence of HDR10+ keeps the format lineup from being complete.

Warranty

LG StanByMe 2
1.0
After-sales support is a serious concern in the few reviews that needed repairs. Customers describe slow parts, confusing replacement or refund processes, and difficulty finding service options.

Banding control
LG C6

Color gamut
LG C6
4.7
DCI-P3 coverage is essentially complete, and tandem-panel versions expand wider-gamut performance further. HDR colors look rich and varied without usually appearing overdone.

Recommendations range from useful and sensible to generic and poorly personalized. The feature may improve as it learns viewing habits.

Dirty screen effect
LG C6
5.0
Uniformity testing found little to no dirty-screen effect during normal viewing, which helps sports and panning shots look clean.
LG StanByMe 2No score yet
Distortion control
LG C6
4.0
Voices and midrange are usually clean at normal levels, but one 48-inch model introduced distortion as volume increased.

G-SYNC compatibility
LG C6

Nvidia G-SYNC compatibility helps maintain clean, tear-free motion for PC gaming.

Gaming dashboard
LG C6
5.0
LG’s Game Optimizer remains one of the most useful dashboards for adjusting latency, VRR, HDR, and genre-specific settings on the fly.

Gaming mode quality
LG C6
4.5
Game Optimizer preserves strong HDR impact and provides quick access to useful controls. Some samples needed tuning, and one 48-inch unit showed reduced color saturation.

Gradient handling
LG C6
5.0
Color transitions are notably smoother than on the C5, with posterization mostly confined to extreme torture-test scenes.

HDMI 2.1 port count
LG C6
5.0
All four HDMI inputs support the full gaming feature set, a major advantage for households with multiple consoles and a soundbar.

High-refresh-rate gaming
LG C6
4.8
The move from 144Hz to 165Hz is a useful upgrade for PC players. One test found intermittent flicker and softness at 165Hz, while 120Hz remained more stable.
LG StanByMe 2No score yet
Judder handling
LG C6
4.7
With the right TruMotion setting, slow camera pans look much smoother and more cinematic without obvious artifacts.

Motion interpolation
LG C6
4.7
Cinematic Movement is effective at smoothing pans while preserving a natural film look. Stronger processing is rarely necessary.

Overall satisfaction
LG C6No score yet
LG StanByMe 2
4.0
Overall sentiment is strongly positive, driven by customers who use the StanByMe 2 daily and love how naturally it moves through the home. The negative tail is meaningful, though, with software frustration, value concerns, and hardware failures producing several very low ratings.
PC text clarity
LG C6No score yet
LG StanByMe 2
3.3
QHD resolution can make text clear enough for a useful secondary display, and some reviewers found it excellent for work. Others found pixel density or wireless 1080p limits too weak for serious monitor use.
Portability and versatility
LG C6No score yet
LG StanByMe 2
4.8
Mobility is the StanByMe 2’s clearest strength: reviewers repeatedly praise the rolling stand, detachable screen, and ability to work in kitchens, bedrooms, patios, offices, and events. A few note that weight, carpet, or awkward handling can reduce that flexibility.
Refresh rate
LG C6
5.0
The native 120Hz panel supports VRR up to 165Hz, giving PC gamers more headroom than the C5.

Remote layout
LG C6
2.5
App shortcuts, the pointer, and a customizable heart button are convenient, but the missing conventional mute button frustrates some users.

Screen uniformity
LG C6
3.5
Most samples were clean across normal brightness levels, but one retail unit showed a visible green glow near the bottom edge and some dark-gray vertical banding.

Search quality
LG C6

AI search can identify content correctly but sometimes fails to launch it, while simpler voice searches generally perform better.

Shadow detail
LG C6
4.0
Dark scenes usually retain fine textures and background objects, though a few units showed black crush or slightly raised near-black tones that benefited from adjustment.
LG StanByMe 2No score yet
Stutter handling
LG C6
3.5
OLED’s fast response can expose stutter in low-frame-rate movies, although interpolation reduces it. Broadcast and fast-edit content generally avoids micro-stutter.

USB port count
LG C6No score yet
LG StanByMe 2
3.0
The added USB-C connectivity is a second-generation improvement that one reviewer explicitly praised. Another buyer still wanted better external USB options, so the port setup will not satisfy every workstation use.
Variable refresh rate
LG C6
4.8
HDMI VRR, FreeSync, and G-SYNC support keep gameplay smooth and largely tear-free. Occasional flicker was reported in demanding PC use.
LG StanByMe 2No score yet
VRR range

VRR extends up to 165Hz for PC gaming while fully covering the 120Hz ceiling of current consoles.

Performance
HDR brightness
LG C6
5.0
The C6 makes a clear brightness jump over the C5, creating more impactful sunlight, clouds, reflections, and specular highlights. Full-screen brightness remains more limited than small-window peaks.
LG StanByMe 2No score yet
Local dimming performance
LG C6No score yet
LG StanByMe 2
2.0
Backlight precision is weak, with larger areas of the screen lighting up when they ideally should remain dark. That hurts contrast control in demanding scenes.
Noise reduction
LG C6
5.0
AI Picture Pro can remove visible noise while preserving fine detail, making compressed or lower-quality material look cleaner.
LG StanByMe 2No score yet
Sustained brightness
LG C6
2.0
Bright full-screen scenes trigger noticeable automatic brightness limiting, so sports and snow-heavy content can look dimmer than small HDR highlights suggest.

Size options

2.0
LG’s assistant, Gemini, and Copilot add voice and AI features, but their usefulness and reliability remain inconsistent.
