For most gamers, the LG OLED C5 is the strongest all-round 120Hz TV choice in the current lineup covered here. The model combines 4K/120Hz and 4K/144Hz input modes, four HDMI 2.1 inputs, variable refresh rate (VRR), automatic low-latency mode (ALLM), Dolby Vision game mode and HGiG. It is available in 42-, 48-, 55-, 65-, 77- and 83-inch sizes. That recommendation comes from What Hi-Fi?’s current gaming-TV guide, so it should be treated as an editorial pick rather than a universal answer for every room, budget or country.
If you prefer an LCD or Mini-LED design, TCL’s 2026 QM7L, QM8L and X11L families offer native 144Hz panels and 4K-at-144Hz HDMI capability. Their HDMI assignments and size ranges differ by family, making the exact model and screen size important. This guide explains what a genuine 120Hz specification means, which sets are worth shortlisting, and how to verify that a television will deliver the signal your console or PC can actually produce.
Quick picks
| TV | Panel and refresh specification | Gaming inputs and features | Best suited to |
|---|---|---|---|
| LG OLED C5 | 4K OLED; 4K/120Hz and 4K/144Hz modes | Four HDMI 2.1 inputs, VRR, ALLM, Dolby Vision game mode and HGiG | Most console and PC gamers who want OLED contrast and flexible connectivity |
| TCL QM7L | Mini-LED/LCD family with native 144Hz | VRR, ALLM and 4K@144Hz HDMI capability; the first two HDMI ports are identified for the high-bandwidth gaming connection in TCL’s comparison | Buyers considering a high-refresh LCD and who can use the specified HDMI ports |
| TCL QM8L | Mini-LED/LCD family with native 144Hz | VRR, ALLM and 4K@144Hz HDMI capability; TCL lists HDMI 2.1 capability across the ports in its comparison | LCD buyers who need several high-bandwidth connections |
| TCL X11L | Mini-LED/LCD family with native 144Hz | VRR, ALLM and 4K@144Hz HDMI capability; TCL lists HDMI 2.1 capability across the ports in its comparison | Those evaluating TCL’s higher-end 144Hz family |
| Sony Bravia 8 | 4K OLED; up to 4K/120Hz | VRR and ALLM with two HDMI 2.1 inputs | PS5 owners who value Sony’s gaming integration and can work within two high-bandwidth ports |
There is no comparable, current price table or independent laboratory dataset covering every model above. Brightness, reflections, input lag and HDR performance should therefore be checked in the exact regional specification and independent test you trust before purchase.

Refresh rate is the number of times a screen updates its image each second. A 120Hz panel can refresh 120 times per second. That capability is separate from frame rate: a console, PC, game engine and cable connection must all deliver a compatible signal before the TV can display 120 distinct frames each second.

120Hz is not the same as 120 frames per second
A 120Hz television can accept or display a 120Hz signal, but many games run at 30 or 60 frames per second. Hisense’s gaming guidance notes that 120Hz output is available on PlayStation 5 and Xbox Series X in selected titles, not automatically in every game. Resolution, graphics mode and the game’s own frame-rate target determine what you see.
In practice, a 120Hz panel can still be useful with 30fps or 60fps content because the display can present those frame rates at even intervals, but it cannot create extra game frames without interpolation. For competitive play, the important question is whether the source offers a genuine 120Hz performance mode at the resolution you want.
Native refresh versus an advertised accelerator mode
Native refresh describes the panel’s actual operating capability. A television may also advertise a Game Accelerator or similar mode that reports a higher number. TCL warns that elevated frame-rate modes can involve a compromise in resolution. Treat a headline such as 240Hz or an accelerator figure as a separate claim from native 4K/120Hz support, and check the resolution accepted on each HDMI input.
Why the LG OLED C5 is the leading all-round pick
What Hi-Fi?’s current gaming-TV guide names the OLED55C5 its best gaming TV overall. The set supports 4K/120Hz and 4K/144Hz, giving console owners the standard 120Hz target and PC players an option for compatible high-frame-rate output. Four HDMI 2.1 inputs make it easier to connect a console, gaming PC, soundbar or receiver without constantly moving cables.
Features that matter in practice
- VRR: Variable refresh rate allows the display to track a game’s changing output, reducing tearing and uneven motion when frame delivery fluctuates.
- ALLM: Auto Low Latency Mode can switch a compatible source and TV into a low-latency game mode automatically.
- Game-format support: The guide lists Dolby Vision game mode and HGiG, useful considerations when your console and games support those HDR workflows.
- Size choice: The C5 guide entry lists 42, 48, 55, 65, 77 and 83 inches, giving more seating-distance options than many gaming-focused lines.
Those specifications do not prove that the C5 is the brightest or lowest-lag set in every market; they establish why it is a well-equipped gaming choice. Check the local model suffix and specification sheet before ordering.
TCL’s 2026 144Hz Mini-LED alternatives
TCL’s North American 2026 comparison covers the QM7L, QM8L and X11L families. Each is listed with a native 144Hz refresh rate, VRR, ALLM and HDMI input capability for 4K at 144Hz. That makes them alternatives for buyers who want an LCD/Mini-LED panel and a refresh ceiling above the 120Hz console target.
QM7L: verify the high-bandwidth ports
TCL’s comparison identifies the first two ports on the QM7L for the relevant HDMI 2.1 connection. If you plan to attach more than two 4K/120Hz-or-higher devices, count your sources and confirm the port labels on the exact size before buying. A receiver or eARC soundbar can also consume a port you expected to use for a console.

QM8L and X11L: broader port listing
The same TCL comparison lists HDMI 2.1 capability across the ports for the QM8L and X11L families. Their available screen-size ranges are different from one another and from the QM7L. Do not assume that a specification from one size or family applies to another; use the model code printed on the retailer listing and the manufacturer’s sheet.
Native 144Hz does not guarantee that every game will run at 144 frames per second. It simply gives compatible PCs and sources a higher ceiling, while consoles generally target 120Hz in supported performance modes.
Sony Bravia 8: a focused 120Hz OLED option
What Hi-Fi?’s gaming guide lists the Bravia 8 with 4K/120Hz, VRR and ALLM. It has two HDMI 2.1 inputs. The review presents it as particularly suitable for PS5 owners, while identifying the limited HDMI 2.1 count and 120Hz ceiling as trade-offs for PC gamers.
Two high-bandwidth inputs can be sufficient for one console and one gaming PC, but the allocation matters if you also use eARC, an AV receiver or a second console. Map your connections before purchase rather than assuming every HDMI socket has identical bandwidth.
OLED, LCD and Mini-LED: choose by room and use
A refresh number does not decide the best panel technology. OLED and LCD/Mini-LED sets are different product families with different strengths in contrast, brightness behaviour, viewing angle and price. The available evidence does not provide a single, comparable measurement set for brightness, reflections, input lag or HDR across all of these models, so avoid treating one technology as automatically superior.
When OLED makes sense
- You want the C5’s four HDMI 2.1 ports and both 4K/120Hz and 4K/144Hz modes.
- Deep contrast and wide viewing angles are priorities for a dark or mixed-light gaming room.
- You can choose a size that fits the seating distance and are comfortable following the manufacturer’s care guidance for a self-emissive panel.
When LCD or Mini-LED makes sense
- Your room is bright and you prefer an LCD/Mini-LED design; verify real-world brightness and reflection handling in an independent test of the exact model.
- You want a native 144Hz specification for a compatible gaming PC.
- You need a particular port layout, size or regional model that is not offered in the OLED line you are considering.
LG’s wider 2026 lineup
LG’s current 2026 gaming guide identifies additional televisions with 4K/120Hz displays and notes that selected models support refresh rates above 120Hz. That is useful for understanding the range, but it is lineup context rather than a comparative image-quality or value test. Check the model-specific page for the exact panel, ports and supported combinations instead of assuming every 2026 LG television matches the C5.
How to verify true 4K/120Hz support before buying
- Write down the exact model code and size. A series name is not enough. TCL explicitly separates its family size ranges and port details, and regional suffixes can change specifications.
- Read the HDMI table, not just the product headline. Confirm that the specific input accepts 3840×2160 at 120Hz. Look for the supported colour depth and HDR combinations as well.
- Count high-bandwidth devices. List each console, PC, receiver and soundbar. Compare that list with the number of HDMI 2.1 ports; the C5 guide entry lists four, while the Bravia 8 entry lists two.
- Check VRR and ALLM ranges. Confirm that your console or graphics card supports the TV’s VRR implementation and that ALLM works with your chosen connection path.
- Confirm the game and source. PS5 and Xbox Series X support 120Hz only in selected titles and modes. On PC, the graphics card, game settings and cable must produce the target signal.
- Check HDR formats. Compare the formats supported by the TV, console, PC and games. Support can vary by manufacturer, region and model suffix.
- Choose the screen size from the room. Measure the wall or stand and estimate seating distance before comparing panel features. A larger panel does not create more frames.
HDMI 2.1, eARC and cable planning
HDMI 2.1 is a useful capability for 4K/120Hz, but the label alone does not guarantee a particular feature on every socket. Manufacturers can implement different combinations of bandwidth, VRR, ALLM and eARC. Verify the input table for the exact television.

eARC can share the physical port you intended for another device, especially when a soundbar or receiver is connected directly to the TV. Draw a simple connection map: console and PC first, audio equipment second, then check whether the remaining ports provide the required bandwidth. If a cable must be replaced, select one appropriate to the source and TV manuals; there is no universal cable SKU that every setup requires.
Getting 120Hz from a console or PC
PlayStation 5 or Xbox Series X
- Connect the console directly to an HDMI input confirmed for 4K/120Hz on your exact TV size.
- Enable the console’s 120Hz or performance-mode option where available.
- Open a game that supports a 120Hz mode and select that mode in its video settings.
- Enable VRR on both the console and TV when supported, then verify the TV’s on-screen signal information.
- If the image falls back to 60Hz, test another certified high-speed cable, another HDMI input and the game’s resolution mode before changing picture settings.
Gaming PC
- Use a graphics output and cable rated for the resolution and refresh combination you want.
- Set the operating system or graphics-driver output to 3840×2160 at 120Hz or 144Hz, depending on the TV and GPU.
- Enable VRR in the driver and TV menus, then activate the game’s matching option.
- Check whether the TV’s high-refresh mode reduces resolution; TCL specifically warns about that possibility in elevated Game Accelerator modes.
- Use the TV’s information panel or the game’s display diagnostics to confirm the actual incoming signal.
Common problems and fixes
The TV shows 60Hz instead of 120Hz
- Move the cable to an HDMI input explicitly rated for 4K/120Hz.
- Disable an AV receiver or splitter temporarily and connect the source directly.
- Set the source output manually to 120Hz and choose a supported resolution.
- Try another cable that meets the source and TV manuals’ bandwidth requirements.
- Check the game itself; many titles offer 120Hz only in a separate performance mode.
VRR causes flicker or disables HDR
- Update the TV and source firmware, then retest with a single direct connection.
- Check the model’s supported VRR range and HDR combinations rather than assuming every mode works together.
- Test a different HDMI input if the set assigns different features to different ports.
You run out of HDMI 2.1 ports
Prioritise the devices that genuinely need 4K/120Hz. A 4K/60Hz source can use a lower-bandwidth input if the TV provides one. If a receiver is consuming a high-bandwidth port, check whether it passes through the required signal or connect the console directly and send audio back using eARC.
Cost, availability and regional model checks
Prices and stock change by country, retailer, screen size and suffix, so there is no defensible single “cheapest” or “best-value” choice from these specifications alone. Compare the exact size across several current listings, include delivery and stand or wall-mount costs, and check the return policy for panel issues. A lower-priced size may have a different port layout or panel specification, while a larger size can move into a different pricing tier. Confirm that the retailer’s model code matches the manufacturer’s regional support page before checkout.

Choose the LG OLED C5 when you want the most complete combination of 4K/120Hz, optional 4K/144Hz, four HDMI 2.1 inputs and broad gaming-format support in the cited guide. Choose a TCL QM7L, QM8L or X11L when a native 144Hz Mini-LED/LCD design better fits your room or PC use, but verify the family-specific port assignment and size. Choose the Sony Bravia 8 when PS5-focused features and a 4K/120Hz OLED appeal to you and two HDMI 2.1 inputs are enough.
Before paying, confirm the exact regional model, screen size, HDMI input map, VRR and ALLM support, HDR formats, and the signal your console or PC can produce. Those checks matter more than a large refresh-rate number printed on a box.

Does 120Hz mean 120 frames per second?
No. 120Hz describes the panel’s maximum update rate. The console, PC and game must actually deliver 120 frames per second for the TV to display 120 distinct frames.
Is 144Hz better than 120Hz for console gaming?
A native 144Hz panel gives a compatible PC a higher ceiling, but current consoles generally target 120Hz. The extra number does not make a game run faster by itself.

You need an input and connection path that explicitly support the required 4K/120Hz bandwidth and features. HDMI 2.1 branding is helpful, but verify the exact port table because implementations differ.
How many HDMI 2.1 ports are enough?
Count every console, gaming PC, receiver and soundbar that needs high bandwidth. The LG C5 guide entry lists four HDMI 2.1 inputs; Sony’s Bravia 8 entry lists two, and eARC may use one of them.
Should I choose OLED or Mini-LED for a bright room?
Both are viable product families. Choose based on your room, reflections, contrast priorities, viewing angle and budget, then consult an independent test of the exact model for brightness and HDR performance.
Can a receiver or soundbar prevent 120Hz?
It can if the receiver, splitter or cable does not pass the required signal, or if it consumes the only suitable TV input. Test a direct console-to-TV connection and return audio over eARC when appropriate.
