Head-to-head
LG C6 vs Samsung S90H: Dolby Vision or a matte screen?
The short answer
Choose C6 when you can control reflections and want Dolby Vision from compatible films and apps. Choose S90H when a lamp or window opposite the screen is a daily compromise. C6 supports Dolby Vision, while S90H trades it for a matte Glare Free screen. Both leave three high-refresh inputs after an eARC soundbar, so two consoles do not force the choice. Neither passes DTS disc audio through the TV. Check that route separately.
Before you choose
The reasoning and the trade-offs
The other person’s lamp can matter more than the film format
A TV in a shared living room is often used while someone reads, does homework or works at the dining table. If their lamp appears directly in the picture and cannot reasonably move, Samsung’s matte finish addresses a recurring household conflict. C6’s Dolby Vision support does not remove that reflection. If most serious viewing happens after those activities finish and the light can go off, the trade changes. C6 can preserve Dolby Vision from compatible titles without sacrificing the three spare high-refresh connections both TVs provide after eARC. Look at the screen position during the actual evening routine, rather than deciding from a bright showroom or a blanket claim that every OLED needs darkness.
What this is based on
Shared-room activities and fixed light placement crossed with documented surface finish and HDR-format support. No quantified reflection improvement or universal bright-room guarantee inferred.
Main trade-off
Samsung S90H 65-inch QN65S90HAEXZA
No Dolby Vision or DTS passthrough. The 65-inch model is not the same panel configuration as the 77-inch version.
LG C6 65-inch OLED65C6PUA
- Choose it for
- Keep Dolby Vision in a compatible streaming or disc setup when the room’s direct reflections are manageable. Its glossy screen can still show a lamp opposite it.
- Connect two consoles and a soundbar without giving up a high-refresh input for either console. The supplied central stand still needs suitable furniture.
- Main trade-off
- The glossy finish can leave a direct reflection visible. No DTS passthrough, despite supporting Dolby Vision video.
Samsung S90H 65-inch QN65S90HAEXZA
- Choose it for
- Use the matte finish when shared activities keep a lamp on or a window reflects toward the screen. Glare Free does not mean sunlight or every reflection disappears.
- Keep several gaming devices connected while using the documented TV-speaker plus Bluetooth listening option. That option does not promise simultaneous eARC soundbar output.
- Main trade-off
- No Dolby Vision or DTS passthrough. The 65-inch model is not the same panel configuration as the 77-inch version.
About this comparison
Choose between the 65-inch LG C6 and Samsung S90H around lamps, films, consoles and disc audio. See which difference affects the room you actually share.
These 65-inch midrange OLEDs are being cross-shopped by buyers with the same mix of streaming, films and console gaming. Their similar high-refresh connectivity makes the room and content path more useful deciding factors than a generic gaming label.
Winner by situation
Start with what you need it to do
A lamp must stay on opposite the screen
Samsung’s matte finish addresses the fixed reflection. It is not a guarantee against all glare.

- Caution
- Samsung S90H 65-inch QN65S90HAEXZA
- Better fit
Dolby Vision films matter and direct reflections are controlled
LG supports the format in a compatible playback path.

Two consoles and an eARC soundbar stay connected
Both leave three high-refresh inputs, so this requirement does not separate them.

The video upgrade will not repair a DTS audio path
A family might choose C6 for Dolby Vision discs and assume the same upgrade preserves every part of the soundtrack. It does not. Neither C6 nor S90H passes DTS through the TV. If the player feeds the TV and sends sound onward by eARC, check the specific disc and player options before buying. A compatible receiver connected directly to the player, or a suitable separate audio output from the player, can take the TV out of that path. This matters even when most viewing uses streaming apps and the problem only appears on a weekend disc. Choose the screen for the room and video requirement once the audio route is settled. A Dolby logo on the television is not a universal disc-compatibility promise.
How we reached this conclusion
Occasional physical-media use crossed with separate video and audio compatibility. Both verified DTS exclusions are held constant, so no false winner is created.
A second console does not require choosing the more expensive offer
Both TVs provide four high-refresh HDMI inputs and use one for eARC. An eARC soundbar, two consoles and a compatible gaming PC can therefore occupy all four connections without using a basic-only TV input for either console. That removes a common reason to stretch the budget from one to the other. It does not establish identical motion, latency or picture quality. The 165 Hz ceiling is also a PC option, not a new PS5 performance mode. If your household only uses a console, select between the room finish, film formats and total installed cost. If a PC is added later, check its output and settings rather than assuming every game will reach the TV’s maximum.
How we reached this conclusion
Several household gaming sources and future PC use crossed with equal port allocation.4−1=3 on both. Equality is used to eliminate a false upgrade reason, not to declare overall performance equal.

What you give up
Every choice has a cost
If you choose LG C6 65-inch OLED65C6PUA
- Selected 65-inch OLED65C6PUA with tabletop stand. Check the exact size rather than applying a 77-inch C6H review.
If you choose Samsung S90H 65-inch QN65S90HAEXZA
- Selected 65-inch QN65S90HAEXZA. Check the current offer and any separate audio-routing equipment needed for discs.
Recommendation switch
The decision flips if...
Dolby Vision is useful and reflections can be managed
Choose LG C6 65-inch OLED65C6PUA. C6 retains the format without giving up the multi-console connection plan.
A reflected lamp or window is the problem you face every day
Choose Samsung S90H 65-inch QN65S90HAEXZA. S90H’s matte screen solves a room constraint that the HDR format cannot.
What matters in practice
Before you choose
You want a good film picture without asking everyone else in the room to turn off their light.
What this comparison cannot tell you
- No claim of identical image quality, latency or brightness.
- No medical benefit inferred from matte coating.
- No guarantee that every Bluetooth device or audio mode works simultaneously.
