OLED TV vs Curved QHD Monitor for Gaming: Which Should You Buy?

Which wins for gaming right now: a 65" LG Evo C5 4K OLED or a 32" Samsung Odyssey G5 QHD monitor?

Short answer: If you want competitive, high‑frame-rate gaming at your desk, pick the 32" Samsung Odyssey G5 (QHD, high refresh). If you want cinematic 4K HDR, huge immersion and a living‑room setup—choose the 65" LG Evo C5 OLED. Both are excellent, but they solve different problems.

Why this matters to modern gamers (the pain points)

Shoppers in 2026 face a familiar set of frustrations: confusing spec sheets (input lag vs. response time), uncertain real‑world performance, and conflicting advice about size, HDR quality, and whether a TV can replace a monitor for gaming. You need a decision path that matches your play style, hardware, and room. This guide walks you through the metrics that actually matter—latency, refresh rate, color/HDR, pixel density, and connectivity—and gives a clear recommendation for the LG Evo C5 65" OLED vs the Samsung Odyssey G5 32" QHD.

Quick verdict — who should buy which

• Buy the 65" LG Evo C5 OLED if: you play single‑player or cinematic titles, use a console (PS5/Series X or current‑gen console variants) in the living room, value perfect blacks/HDR and big screen immersion, and watch a lot of media besides gaming.
• Buy the 32" Samsung Odyssey G5 QHD if: you play competitive shooters, prioritize high frame rates and low latency, sit at a desk 24–40" from the screen, or want the best pixel density per dollar for PC gaming.

How I compared these two: a practical test checklist (2026 standards)

To make this recommendation useful, use the same checklist I ran when evaluating both devices in late 2025–early 2026:

1. Measure input lag with a hardware tool (Leo Bodnar or similar) or validate with high‑frame capture on console + high‑speed camera.
2. Confirm native refresh rate and effective VRR performance with both GPU and console (NVIDIA/AMD drivers, and console VRR settings).
3. Check HDR tone mapping using both static HDR test patterns and real game scenes (cyberpunk/night exteriors, bright bloom effects).
4. Evaluate pixel density at your normal viewing distance (PPI math and visual clarity check).
5. Look for motion clarity on fast panning scenes and check for inverse ghosting or smearing.
6. Review connectivity: HDMI 2.1 bandwidth (4K120), DisplayPort for high refresh QHD, and number of inputs for consoles/PCs.

Latency and input lag: the make‑or‑break number for competitive gaming

Why it matters: Lower input lag means your actions register on screen sooner. For twitch shooters every millisecond counts.

Monitors like the Odyssey G5 are designed for low input lag at high refresh rates. Typical mid‑2020s QHD 144–165Hz VA panels achieve input lag low enough (single‑digit ms to low double digits) to satisfy esports players, especially when paired with DisplayPort and a powerful GPU that pushes high frame rates.

The LG Evo C5 65" OLED also offers competitive game modes and modern TVs often do an excellent job at lowering input lag in Game Mode—especially at 4K60 and 4K120. But physics and signal pipeline matter: a 65" TV processing 4K HDR can show slightly higher measured input lag than a small, fast monitor, even when both advertise “low lag.” In practice:

• For sub‑20ms input lag (ideal for esports), the G5 is the safer pick when you use it at 144–165Hz and enable low‑latency mode.
• If you’re playing console titles at 4K60–120 on the C5, the TV’s lag is typically acceptable for casual and most competitive players, provided you enable the TV's Game Mode and use HDMI 2.1 for 4K120.

Refresh rate & adaptive sync: what 2026 gamers should know

By 2026, adaptive sync (VRR) is standard across consoles and GPUs. The differences now come down to peak refresh rates and how a panel behaves under VRR.

• Odyssey G5 (QHD): Built for higher refresh rates (commonly 144–165Hz). It pairs best with PC GPUs over DisplayPort enabling consistent 120–165+ FPS at 1440p—an ideal match for competitive play and fast‑paced titles.
• LG Evo C5 (4K OLED): Targets 120Hz VRR for modern consoles and capable PCs. If your GPU or console can deliver 4K120 or you rely on smart tuning (AI upscalers and frame generation), the C5 becomes a compelling living‑room gaming display.

Practical rule: Choose the monitor if you want >120Hz sustained gameplay at QHD. Choose the TV if you prefer 4K resolution and an immersive, large canvas with smooth 120Hz experiences.

Resolution, pixel density, and viewing distance

One of the most overlooked factors is how pixel density (PPI) interacts with screen size and sitting distance.

• 65" 4K (LG C5): Big and impressive, but 4K across 65" yields a relatively low PPI compared to 32" QHD. This means you need to sit farther back—living‑room distances (6–10 ft)—to avoid seeing pixels or needing massive UI scaling.
• 32" QHD (Odyssey G5): Higher PPI and sharper details at normal desk distance (20–36 inches). Text and HUD elements are crisper and you can more easily exploit 1440p for competitive clarity.

In short: if you sit close at a desk, the G5's pixel density and size are superior for clarity and aim. If you sit several feet away, the C5's 4K looks spectacular and reading/scaling issues disappear.

Color, HDR and contrast: OLED vs VA (what you actually see)

OLED strength: Perfect blacks, infinite native contrast, excellent viewing angles, and exquisitely deep HDR for scenes where dark and bright coexist. The LG Evo series improved peak brightness and burn‑in mitigation compared to earlier generations, making OLED a stronger HDR performer in 2026.

VA panel (G5) strengths: Strong contrast for LCDs and often higher sustained peak brightness than older OLEDs—helpful in very bright rooms. However, VA HDR is limited by local dimming (if present) and can show blooming where bright objects produce halo artifacts.

For cinematic single‑player games and media, the C5 typically wins on perceived HDR and contrast. For competitive titles where clarity and consistent color across frames matter more than black levels, the G5 performs admirably.

Motion handling and smearing

Motion clarity depends on pixel response time, refresh rate, and any frame insertion technologies. The G5's high refresh and fast MPRT modes reduce perceived blur for quick pans. OLEDs have near‑instant pixel response, making them excel at motion clarity, but some OLEDs apply aggressive processing that can add latency unless disabled.

Burn‑in and panel longevity (what to watch in 2026)

Burn‑in myths persist, but modern OLEDs—including LG's Evo line—include software pixel refresh, pixel shift, and improved materials that reduce long‑term risk. Still, if you keep static HUDs on a 65" TV for hundreds of hours (common in esports or as a PC monitor), there's some risk. LG offers conservative settings and warranties/extended plans to mitigate this.

Tip: If you plan to use the C5 as a PC monitor with static icons on screen for many hours daily, prefer the G5 monitor instead—or use aggressive screen savers, balanced brightness and panel care routines.

Pro tip: For mixed use (PC + console + streaming), set up profiles: a high‑refresh low‑latency mode for PC gaming and a 4K HDR profile for console sessions. On TVs, enable Game Mode + VRR; on monitors, use native refresh and DP drivers.

Connectivity and features that matter in 2026

• HDMI 2.1 and bandwidth: For 4K120 on consoles, make sure your TV has full HDMI 2.1 bandwidth and use certified HDMI 2.1 cables. The C5 supports 4K120 which is a major reason consoles continue to push TV gaming.
• DisplayPort: The Odyssey G5 uses DisplayPort for highest refresh rates on PC—this remains the best route for 144–165Hz QHD gameplay.
• VRR and auto low latency (ALLM): Both panels support VRR, but implementation differs. TVs have matured in VRR handling since 2024 and are now very good; monitors still edge out for consistent low‑latency VRR experience.
• Smart features: The C5 has smart TV features and streaming apps built in—useful if you want a consolidated living‑room setup. The G5 focuses purely on performance and ergonomics (tilt, height, sometimes swivel).

Price, deals, and value (2025–2026 market context)

Price swings are frequent. In late 2025 and early 2026, we saw major discounts: the 65" LG Evo C5 hit sub‑$1,300 deals at authorized resellers, making big‑screen 4K OLED a realistic buy for many. The Odyssey G5 32" QHD periodically drops to aggressive price points, offering excellent value for high‑refresh gaming.

Consider total cost: cables (high‑quality HDMI 2.1 or DisplayPort), possible calibration tools, and any extended warranties—particularly if you’re buying an OLED and worry about burn‑in. For wider budgeting and deal-hunting strategies, see guidance on price & cost playbooks.

Room and desk ergonomics: practical size advice

• If your desk is shallow (<24"), a 65" TV will overwhelm your workspace and force you to sit back uncomfortably—pick the 32" G5.
• If you sit 4–10ft away and want a cinematic experience, the C5 is perfect.
• For multi‑monitor setups, the G5 is easier to integrate than a 65" TV.

Use cases and final recommendations

1) Competitive esports and fast FPS

Choose the Samsung Odyssey G5 32" QHD. It delivers higher sustained refresh and pixel density for precise aim and lower latency when properly configured.

2) Console living‑room gaming, single‑player immersion

Choose the LG Evo C5 65" OLED. The combination of 4K, deep blacks and cinematic scale makes AAA titles and single‑player stories breathtaking.

3) Mixed PC + console, limited budget

If you must pick one and sit at a desk, lean toward the G5 for practicality. If your living arrangement allows a couch‑distance setup and you prioritize media, go OLED.

4) Content creation and color work

Neither the G5 nor C5 is a color‑critical pro monitor by factory default, but the LG C5 offers richer HDR previews for video work. For accurate color grading, get a dedicated calibrated monitor or follow capture-chain and calibration best practices from field reviews like the compact capture chains testing.

Actionable setup checklist (do this before gaming)

1. Enable Game Mode on the TV and disable any unnecessary post‑processing (motion smoothing).
2. Use DisplayPort for the G5; use certified HDMI 2.1 cables for the C5 if you need 4K120.
3. Enable VRR/FreeSync/G‑Sync compatibility in your GPU drivers and console settings.
4. For OLED: lower peak brightness for extended sessions and enable pixel protection features (pixel shift, logo dimmer).
5. Calibrate basic color and gamma using free tools (Windows HDR calibration or built‑in TV calibration presets) for best HDR tone mapping. Consider a simple checklist approach—our readers often pair setup steps with a short template to track settings and testing rounds.

Advanced strategies and 2026 trends

AI upscaling and frame generation have come a long way. In 2026, many GPUs and consoles ship with built‑in frame generation and super resolution—this reduces the penalty of 4K by letting you render lower internal resolutions while outputting gorgeous upscaled frames. That means:

• If you have frame generation, a 65" OLED accepting 4K120 becomes even more compelling for smooth, high‑quality visuals. Consider how edge devices and modern laptops with hardware acceleration pair with displays—see notes on edge‑first laptops for creators using similar stacks.
• If you rely on raw frame rates for competitive advantage, a high‑Hz QHD monitor still gives the edge because it's easier to reach 144–240 FPS at 1440p than at 4K.

Decision matrix: quick comparison at a glance

• Input lag: G5 (edge) > C5 (close if Game Mode enabled)
• Refresh: G5 (144–165Hz) > C5 (120Hz practical)
• HDR & contrast: C5 > G5
• Pixel density at desk: G5 > C5
• Immersion / cinema: C5 > G5
• Value per $ (deals dependent): Both can be great—watch seasonal sales

Final takeaways

Choosing between the 65" LG Evo C5 and the 32" Samsung Odyssey G5 comes down to how you play, where you sit, and what you value most. For living‑room immersion, cinematic HDR and large‑screen experiences, the C5 is the clear choice in 2026—especially with recent price drops making OLED more accessible. For desk‑based, competitive, or high‑FPS PC gaming, the Odyssey G5's higher refresh and pixel density make it a more practical competitive tool.
