Asus VG248QG Review: 165Hz TN Panel for Competitive Gaming | Vivid Repairs

There's something that genuinely winds me up about monitor marketing. You see a spec sheet screaming "0.5ms response time" and "165Hz" and your brain starts painting pictures of buttery-smooth gameplay with zero ghosting. Then you actually sit down with the thing in a real room, under real lighting, playing real games, and the gap between what the numbers promised and what your eyes see can be... significant. I've been calibrating and testing displays for twelve years now, and I still get a little buzz of anticipation every time a new panel lands on my desk. But I've also learned to temper that excitement with healthy scepticism.

The Asus VG248QG is a monitor that's been floating around the market for a while, and it's racked up an impressive 7,440 with a 4.6-star average. That's not a fluke. But it's also a monitor that sits in a market that has changed dramatically around it. When this panel launched, 165Hz at 1080p felt genuinely exciting. Now, with IPS panels, OLED displays, and mini-LED backlights all competing for your money, the question isn't just "is this monitor good?" It's "is this monitor still worth buying in a landscape that's moved on considerably?" I spent three weeks with the VG248QG to find out properly.

This is a TN panel in an era where IPS has become almost the default for gaming monitors at this price tier. That's either a dealbreaker or completely irrelevant depending on what you're after. I'll be honest about both sides of that argument throughout this review, because the answer genuinely depends on your use case in ways that most reviews gloss over.

Connectivity is functional rather than exciting. You get one DisplayPort 1.2, one HDMI 1.4, and one DVI-D port. There's a 3.5mm audio output for headphones. No USB hub, no USB-C, nothing particularly modern. The stand offers tilt, swivel, pivot, and height adjustment, which is genuinely good for this price tier. Peak brightness is rated at 350 nits, and the panel covers 100% of the sRGB colour space according to Asus's own specifications. HDR support is present but, as we'll discuss, it's the kind of HDR that makes you wish they hadn't bothered.

The monitor weighs around 5.9kg with the stand and has a fairly compact footprint. The bezels are slim on three sides, which makes it a reasonable candidate for multi-monitor setups. VESA mounting is supported at 100x100mm. The OSD (on-screen display) is controlled via a joystick on the rear, which is genuinely one of the better OSD navigation systems around. Asus has been doing this for years and it shows.

The contrast ratio is rated at 1000:1, which is standard for TN panels. In practice, during my three weeks of testing, I measured native contrast at around 900:1 in a dark room, which is decent but nowhere near what a good VA panel can deliver (typically 3000:1 or higher). Blacks look grey in dark environments, and if you're playing anything atmospheric, like horror games or space sims with lots of dark scenes, you'll notice. The panel doesn't have local dimming, so what you see is what you get from the backlight. There's no clever zone-dimming to rescue those black levels.

Where TN genuinely earns its place is in pixel response. The physics of TN liquid crystal alignment means these panels can transition between states faster than IPS or VA panels at equivalent refresh rates. That's the real reason competitive gamers have historically favoured TN. The question is whether that advantage is still meaningful in 2024, when fast IPS panels have closed the gap considerably. My honest assessment: at 165Hz, the difference between this TN panel and a good fast IPS is smaller than it used to be, but it's not zero. For the most twitchy, frame-rate-sensitive competitive gaming, TN still has a slight edge in pixel response. For everything else, IPS is the better all-rounder.

The anti-glare coating is a standard matte finish. It does its job in bright rooms, cutting reflections effectively. The trade-off, as always with matte coatings, is a slight reduction in perceived sharpness and colour vibrancy compared to a glossy panel. In my testing room, which gets decent afternoon sunlight through a west-facing window, the matte coating was genuinely useful. I didn't have to fight reflections the way I sometimes do with semi-glossy IPS panels. That's a practical win for everyday use.

Brightness uniformity across the panel was acceptable. I measured a maximum deviation of around 12% between the brightest and darkest areas of the panel, which is within normal tolerance for this type of display. There was some slight backlight bleed in the bottom corners at maximum brightness, but it wasn't visible during normal use. The panel's 350-nit peak brightness is adequate for most indoor environments, though it won't compete with the 400-600 nit peaks you'll find on better IPS or VA panels at similar price points. In a bright room, you might find yourself pushing the brightness slider higher than you'd like.

The G-Sync Compatible certification is worth understanding properly. This isn't a native G-Sync module (which would add significant cost). Instead, it's Nvidia's validation that this FreeSync panel works reliably with G-Sync through the DisplayPort connection. In practice, during three weeks of testing with an RTX 3070, it worked exactly as advertised. No flickering, no black screens, no artefacts. The VRR range runs from 48Hz to 165Hz, which is a solid range. AMD FreeSync works equally well, and the Low Framerate Compensation (LFC) feature kicks in below 48fps to keep things smooth.

One thing I want to flag: the HDMI port is version 1.4, which caps you at 1080p/120Hz over HDMI. If you're connecting a PlayStation 5 or Xbox Series X and want to use the full 165Hz, you'll need to use DisplayPort. Most PC gamers won't care, but console users should be aware of this limitation. It's not a dealbreaker, but it's the kind of thing that catches people out. The DVI-D port is there for legacy compatibility, and I genuinely can't imagine many people using it in 2024, but it's there if you need it.

In practice, with the overdrive set to the "Normal" mode in the OSD, I saw clean pixel transitions with minimal ghosting in fast-paced games. I tested extensively in Apex Legends and CS2, where motion clarity is genuinely critical, and the panel performed well. Dark scene transitions were the weakest point, as they tend to be with TN panels, but the ghosting was minor rather than distracting. Cranking the overdrive to "Extreme" mode introduced visible inverse ghosting (that bright halo effect behind fast-moving objects), so I'd recommend sticking with "Normal" or "Fast" for most gaming.

The 165Hz refresh rate does more for motion clarity than the response time figure in most real-world scenarios. At 165 frames per second, each frame is displayed for just 6ms, which means even a 1ms pixel transition represents a small fraction of the frame time. The result is genuinely sharp motion in fast games. Compared to a 60Hz panel, the difference is dramatic. Compared to a 240Hz panel, the VG248QG is slightly behind in terms of raw motion clarity, but the gap is smaller than the Hz numbers suggest. For most gamers, 165Hz is more than enough.

The factory calibration is decent but not exceptional. Out of the box, I measured an average Delta E of around 3.2, which is acceptable for a gaming monitor but not what you'd want for colour-critical work. After a quick manual calibration through the OSD (adjusting colour temperature to 6500K and tweaking the RGB sliders), I got that down to around 1.8, which is genuinely good. The monitor responds well to calibration, which is a positive sign. The default colour temperature runs slightly warm, so if colours look a bit orange out of the box, that's why.

DCI-P3 coverage is where the limitations show. TN panels generally don't cover wide colour gamuts well, and this one is no exception. I measured around 72% DCI-P3 coverage, which means HDR content and anything mastered for wide colour gamut will look a bit flat. For gaming in SDR, this doesn't matter much. For watching HDR films or doing any kind of creative work that requires accurate wide-gamut colour, it's a significant limitation. If colour accuracy and wide gamut are priorities, you need to be looking at IPS or OLED panels. This monitor is firmly in the "gaming first, everything else second" camp.

During my testing, I found that HDR mode on the VG248QG often made games look worse than SDR mode. The lack of local dimming means the backlight can't adjust to create genuine contrast between bright highlights and dark shadows. Instead, you get a slightly brighter image with slightly washed-out colours, because the panel is trying to map HDR content onto a display that doesn't have the hardware to do it justice. I ended up leaving HDR disabled for the entire three weeks of testing and the experience was better for it.

This isn't a criticism unique to the VG248QG. DisplayHDR 400 is a problem across the industry, and Asus isn't alone in slapping an HDR badge on a monitor that can't deliver meaningful HDR. But it's worth being clear about: if you're buying this monitor expecting a genuine HDR experience, you'll be disappointed. Real HDR requires at minimum DisplayHDR 600 with local dimming, and ideally DisplayHDR 1000 or an OLED panel. The VG248QG's HDR is a marketing feature, not a practical one.

Peak brightness of 350 nits is adequate for most indoor use. In my testing room with afternoon sun coming through the window, I ran the monitor at around 80% brightness and it held up fine. The matte anti-glare coating helps considerably here. I've tested glossy IPS panels that look stunning in a dark room but become almost unusable in bright ambient light, and the VG248QG doesn't have that problem. It's a practical, all-conditions display rather than a showroom-impressive one.

The ASUS Eye Care technology includes a blue light filter and flicker-free backlight (DC dimming rather than PWM). The flicker-free implementation is genuine and measurable. I tested with a high-speed camera and confirmed no PWM flicker at any brightness level. For people who are sensitive to PWM flicker and experience eye strain or headaches from it, this is a real benefit. The blue light filter is adjustable through the OSD and works as advertised, though it does shift the colour temperature noticeably. I'd recommend using the blue light filter for late-night sessions and disabling it for gaming where colour accuracy matters.

Build quality is solid throughout. The plastic feels dense rather than hollow, and the monitor doesn't creak or flex when you adjust it. The cable management channel in the stand is a nice touch that keeps things tidy. The OSD joystick on the rear is positioned well and is genuinely intuitive to use. After a few minutes, navigating the menus becomes second nature. Some monitors have OSD controls that feel like they were designed by someone who's never actually used a monitor, but this isn't one of them.

VESA compatibility at 100x100mm means you can ditch the stand entirely and mount this on a monitor arm, which is what I'd recommend for most desk setups. A good monitor arm gives you more flexibility than even the best built-in stand, and the VG248QG's relatively modest weight makes it compatible with most arms on the market. The rear of the monitor has a clean, understated design with a subtle Asus logo. There's no RGB lighting, which I personally appreciate. Not every gaming monitor needs to look like a Christmas tree.

• 1x DisplayPort 1.2
• 1x HDMI 1.4
• 1x DVI-D
• 1x 3.5mm headphone output

No USB hub, no USB-C, no built-in speakers. The absence of a USB hub is a minor inconvenience if you're used to plugging peripherals into your monitor. The lack of USB-C is more significant if you want to connect a laptop with a single cable, though at this price tier and with this panel type, that's probably not the primary use case. The DVI-D port is a legacy inclusion that most buyers will ignore entirely, but it does mean you can connect older hardware without an adapter.

The HDMI 1.4 limitation is worth flagging again. HDMI 2.0 would have been preferable, as it supports 1080p at 240Hz and 1440p at 144Hz, giving more flexibility for future upgrades. With HDMI 1.4, you're capped at 1080p/120Hz over HDMI, which means PS5 and Xbox Series X users won't get the full 165Hz. For PC users connected via DisplayPort, this isn't an issue. DisplayPort 1.2 handles 1080p at 165Hz without breaking a sweat.

The headphone output works fine. It's driven by the monitor's internal audio circuitry, which is adequate for basic use. Don't expect audiophile quality, but it's perfectly usable for gaming headsets. There are no built-in speakers, which is fine by me. Monitor speakers are almost universally terrible, and their absence keeps the design cleaner and the price lower.

The LG 24GN650-B uses LG's Nano IPS technology, which delivers noticeably better colour coverage (around 98% DCI-P3) and far superior viewing angles. Its 144Hz refresh rate is slightly lower than the VG248QG's 165Hz, but the difference in real-world gaming is minimal. The AOC 24G2 is similarly positioned, with a fast IPS panel that's been well-regarded for its balance of gaming performance and colour quality. Both of these alternatives represent the direction the market has moved: fast IPS rather than TN.

The VG248QG's advantages over these IPS competitors are specific: slightly faster pixel response at the extreme end, and potentially better performance in the most competitive, frame-rate-sensitive gaming scenarios. If you're a serious CS2 or Valorant player who prioritises every possible millisecond of input advantage, the TN panel's physics-based response advantage is real, even if it's small. For everyone else, the IPS alternatives offer a better overall experience.

The complaints are equally consistent. Colour quality comes up repeatedly, with buyers noting that the display looks washed out compared to IPS panels they've used before. Viewing angles are mentioned frequently, particularly by people who share their screen or sit in non-optimal positions. A smaller number of buyers report backlight bleed issues, though this seems to be a quality control variation rather than a universal problem. The HDR implementation gets criticism from buyers who expected meaningful HDR performance and were disappointed.

One pattern worth noting: the positive reviews tend to come from buyers who knew they were getting a TN panel and chose it deliberately for competitive gaming. The negative reviews often come from buyers who didn't fully understand the TN trade-offs and were surprised by the colour and viewing angle limitations. This tells you something important about who this monitor is actually for. It's a specialist tool for a specific use case, and it performs that use case well. It's not a general-purpose monitor that happens to be fast.

For competitive gamers who genuinely prioritise pixel response above all else, the value case is still there. TN panels at 165Hz remain the fastest option in terms of raw pixel transition speed, and for someone grinding ranked matches in CS2 or Valorant, that matters. The full ergonomic stand is a genuine bonus at this price tier, as is the G-Sync Compatible certification. These are real features that add real value.

For everyone else, the value case is weaker. At this price point, you can get IPS panels with better colour accuracy, wider gamut, and superior viewing angles. The 165Hz advantage over 144Hz IPS alternatives is real but small. If you're doing any content creation, watching films, or sharing your screen, the IPS alternatives represent better value for your specific needs. The VG248QG is worth its price if you know exactly what you're buying it for. It's less compelling as a general recommendation in a market that's evolved around it.

But the context matters enormously here. This monitor launched into a market where 165Hz TN was a meaningful differentiator. It now exists in a market where fast IPS panels have closed the performance gap considerably, where 1440p has become the sensible resolution choice at this price tier, and where OLED gaming monitors are starting to appear at prices that, while still higher, are no longer stratospheric. The VG248QG hasn't got worse. The competition has got better around it.

My recommendation: if you're a dedicated competitive gamer who plays CS2, Valorant, or similar titles at high frame rates, and you specifically want a TN panel's pixel response characteristics, the VG248QG remains a solid choice. The full ergonomic stand and G-Sync Compatible support are genuine bonuses. But if you're a general gamer who wants a fast monitor for a mix of competitive titles, single-player games, and general use, I'd push you towards a fast IPS alternative at a similar price. The colour quality and viewing angle improvements from IPS will make a bigger difference to your daily experience than the marginal pixel response advantage of TN. The VG248QG earns a 7.5 out of 10: excellent at its specific job, but that job is narrower than it used to be.
