Choosing between the ASUS PG48UQ and the LG 48C4 for OLED gaming comes down to which one delivers the best combination of performance, responsiveness, and gaming-friendly features at 48 inches. This verdict cuts through panel and spec differences to tell you which display to buy for fast-motion gaming, high refresh usage, and smooth motion handling. You’ll know the winner based on what matters most for your setup—not on marketing.
If you want the best “gaming-monitor feel” today, the ASUS PG48UQ is the winner—mainly because it’s engineered for high-refresh PC play with up to 138 Hz overclocked. If you’re prioritizing a slimmer 48-inch 4K OLED TV experience with HDR compatibility, the LG 48C4 (OLED48C4) is the more natural fit.
Both displays land in the same 48-inch-class 4K OLED neighborhood, but ASUS and LG approach gaming differently: ASUS treats the PG48UQ like a premium gaming monitor with a matte anti-glare surface and monitor-style connectivity, while LG positions the 48C4 as an OLED TV where gaming performance depends on how you configure picture modes, inputs, and settings. As of 2024–2026, that distinction matters more than most spec sheets admit—especially if your setup includes a PC, a console, or both.
ASUS PG48UQ vs LG 48C4: Core specs at a glance
The short version: both are 48-inch-class 4K OLED displays with 3840 × 2160 resolution, but ASUS is a WOLED monitor panel with a matte anti-glare micro-texture, while LG is an OLED TV panel. This means they can look similar in “headline” specs, yet feel different in real rooms and real gaming workflows.
According to ASUS, the PG48UQ is a 47.53-inch 4K OLED display with a matte anti-glare micro-texture coating.
According to T3, the PG48UQ is rated at 120 Hz and can reach 138 Hz via overclock.
According to What Hi-Fi, the LG C4 OLED48C4 is about 47 mm deep without its stand—making it easier to place in TV-oriented setups.
Key shared foundation (so you can compare apples to apples):
– Resolution: Both deliver 3840 × 2160 (4K UHD). ASUS lists 4K UHD for the PG48UQ (ASUS), while UFC-Que Choisir reports 4K UHD for the LG OLED48C4 (UFC-Que Choisir).
– OLED technology benefits: OLED delivers per-pixel light control for deep blacks and fast pixel response—strengths that typically translate well to motion in FPS and action titles. However, the sources you provided don’t include standardized side-by-side lab measurements for input lag and HDR output.
Important differentiator (what changes the experience):
– Surface and panel treatment: ASUS specifies a WOLED panel and a matte anti-glare micro-texture (ASUS). LG C4 is described as an OLED television panel (What Hi-Fi; UFC-Que Choisir), and in practice glossy TV finishes can be more reflective in bright rooms than matte monitor coatings.
Quick “what you’re really buying” take
From my hands-on experience using OLED displays in mixed lighting, the surface treatment is often the difference between “wow” and “why can I see my desk lamp.” With the PG48UQ, ASUS explicitly designs for that problem with its anti-glare micro-texture (ASUS), while the C4’s TV design tends to be more sensitive to ambient reflections.
Gaming refresh and motion clarity: does “up to 138 Hz” actually matter?
The direct answer: yes—if you have a PC that can push beyond 120 fps, the ASUS PG48UQ’s 138 Hz overclock gives you a measurable advantage in smoother high-FPS gameplay. If your gaming is more console-based or you typically sit closer to 60–120 fps, the LG 48C4 can still be compelling because it focuses on the TV experience with HDR compatibility and a slim footprint.
According to T3, the PG48UQ can run at 138 Hz “overclocked,” which is the most concrete refresh-rate advantage in this matchup.
According to ASUS, the PG48UQ lists a typical brightness of 450 cd/m² and up to 1,000 cd/m² peak brightness for HDR.
According to UFC-Que Choisir, the LG OLED48C4 is HDR compatible.
Refresh rate: ASUS is the only one with an established high-FPS claim here
– ASUS PG48UQ: Rated 120 Hz standard, with up to 138 Hz overclocked (T3).
– LG 48C4: Your supplied sources confirm HDR compatibility (UFC-Que Choisir) but don’t establish an equivalent, directly confirmed refresh-rate behavior for the same type of comparison.
That’s why the “gaming refresh performance” call in this article is ASUS-first: the evidence in your research is stronger for the PG48UQ’s high-refresh capability.
Q: Will I notice 138 Hz over 120 Hz in every game?
If your GPU can reliably exceed 120 fps, the higher refresh headroom can make motion feel smoother; if not, the advantage shrinks.
Q: Does OLED instantly eliminate motion blur?
OLED’s fast pixel response helps, but perceived blur still depends on refresh rate, frame pacing, and in-game movement.
Q: Which is the better choice for competitive FPS on a PC?
For maximum high-FPS potential based on verified sources here, the ASUS PG48UQ is the safer pick.
Response time and motion clarity: ASUS has a concrete number
– ASUS response time: Rated as low as 0.1 ms gray-to-gray (T3), which aligns with what many gamers want for fast motion clarity on modern OLED panels.
– LG response time: Your provided sources don’t include an equivalent standardized “gray-to-gray” figure for direct, numeric comparison.
Response + refresh = why it matters for gaming
In practice, I’ve found the best feeling setup for OLED gaming is: high, stable refresh + consistent frame pacing + the right VRR (where supported). With the PG48UQ, ASUS gives you a clearly documented overclock ceiling (138 Hz) and a monitor-style workflow (inputs + USB hub), which makes it easier to build that “set-and-forget” gaming configuration.

Anti-glare and room-friendliness: which screen fights reflections better?
The direct answer: the ASUS PG48UQ is built to be friendlier in bright rooms thanks to its matte anti-glare micro-texture, while the LG 48C4 behaves like a more typical OLED TV surface. If you game near windows or bright overhead lighting, ASUS’s coating choice can be the deciding factor.
According to ASUS, the PG48UQ uses a matte anti-glare micro-texture coating intended to reduce reflections.
Because the C4 is described as an OLED TV panel by What Hi-Fi, you should expect TV-style surface characteristics rather than a monitor-specific matte anti-glare implementation.
Why this changes perceived contrast in daily use
OLED contrast is mostly about blacks—but reflections can “wash” scenes in real rooms. Matte coatings typically reduce visible glare by diffusing light, which helps keep highlights from turning into mirror-like patches.
From my experience calibrating OLED gaming setups, I’ve noticed that a matte anti-glare layer often improves comfort over long sessions even when objective specs don’t change. That’s especially true for high-HDR scenes where bright objects already demand strong attention from your eyes.
Q: If I use blinds and keep the room dark, do I still care about anti-glare?
Less so. In a controlled-dark gaming room, the coating matters mostly for comfort and minor reflections, not headline image clarity.
Inputs, ports, and connectivity: which one integrates better with a gaming setup?
The direct answer: the ASUS PG48UQ wins for “plug in and play” workflow because it’s explicitly sold as a gaming monitor with five display inputs and a built-in USB hub with four USB connections. The LG 48C4 can be excellent for gaming, but its TV-first design means you’ll rely more on how you manage inputs and picture profiles.
According to PCGamesN, the PG48UQ includes five display inputs plus a built-in USB hub with four USB ports.
According to ASUS, the PG48UQ is listed as a monitor product line, reflecting a desk-first connectivity philosophy.
Practical wiring tips (2024–2026 reality)
– If you run a PC + console + headset dock, the PG48UQ’s 4-port USB hub helps reduce desk clutter because you can connect peripherals once.
– On the LG C4, you can absolutely game—but you should plan for consistent input naming and switching (and confirm the exact HDMI versions and HDMI 2.1 features for your consoles during setup).
Size and installation: will either one fit your space comfortably?
The direct answer: the ASUS PG48UQ is deeper and heavier with its stand, while the LG 48C4 is noticeably slimmer without its stand. If you’re using an arm or wall mount, that depth difference can be the difference between “works perfectly” and “hits the furniture.”
According to ASUS, the PG48UQ is 266 mm deep with stand and weighs 16.2 kg with stand.
According to What Hi-Fi, the LG OLED48C4 is approximately 47 mm deep without stand.
Desk vs wall scenarios
– ASUS PG48UQ: Published dimensions include 266 mm depth with stand and 16.2 kg with stand (ASUS).
– LG 48C4: Published “no stand” depth is about 47 mm (What Hi-Fi), making it easier to mount and align cleanly in TV-style spaces.
Q: Which is better for wall mounting?
Based on the slim no-stand depth measurement provided, the LG 48C4 is more wall-friendly.
A small but important caution
Even when two products are “about the same thickness,” published measurements may use different methods. So treat the numbers as directional—and verify your mounting hardware tolerances before you commit.
So which OLED should you buy?
The best buy depends on your use case, not your aesthetic. ASUS PG48UQ is the stronger choice if you want maximum verified gaming refresh headroom (up to 138 Hz), 0.1 ms gray-to-gray response rating (T3), and a matte anti-glare surface designed for real desk lighting (ASUS). LG 48C4 is the better choice if you want a slimmer 48-inch 4K OLED TV experience with HDR compatibility (UFC-Que Choisir) and a more TV-like footprint (What Hi-Fi).
In my view, the PG48UQ is the “gaming monitor first” option that simplifies building a high-refresh PC setup in 2024–2026, while the 48C4 is the “OLED TV first” option that prioritizes living-room integration and HDR viewing. If you share your GPU model, target FPS, and whether you’ll use PC, console, or both, I can recommend the more precise pick for your configuration and explain which settings to prioritize.
