The ASUS TUF Gaming VG27AQ is our starting point for an RTX 3070: its 27-inch 1440p panel combines a high refresh ceiling, G-SYNC Compatible certification and an adjustable stand. Choose the smaller VG249Q3A if you prefer 1080p and a 180Hz display, or the VG289Q1A if a 28-inch 4K workspace matters more than refresh rates above 60Hz. These are three different priorities, so match the monitor to how you actually use the PC.
A monitor’s refresh rate is not a promise that an RTX 3070 will render games at that frame rate. Game, resolution, quality settings and the rest of the PC determine what the GPU can deliver. This guide concerns desktop RTX 3070 setups. NVIDIA’s reference desktop RTX 3070 has 8GB of GDDR6 memory and HDMI plus three DisplayPort outputs; check the specifications of your particular board, because partner-card connectors can differ. A laptop’s external ports and GPU routing must be checked with its own manufacturer.
Best monitors for RTX 3070 at a glance
| Monitor | Panel and resolution | Maximum refresh and connection | Variable refresh | Main tradeoff |
|---|---|---|---|---|
| ASUS TUF Gaming VG27AQ | 27-inch IPS; 2560 × 1440 | 165Hz over DisplayPort with overclocking; HDMI up to 144Hz | NVIDIA G-SYNC Compatible; Adaptive-Sync | 165Hz is an overclocked mode; reduce it if unstable |
| ASUS TUF Gaming VG249Q3A, black | 23.8-inch IPS; 1920 × 1080 | Up to 180Hz; DisplayPort 1.2 or HDMI 2.0 | Adaptive-Sync; AMD FreeSync Premium; NVIDIA certification not established here | Lower resolution and no stand height adjustment |
| ASUS TUF Gaming VG289Q1A | 28-inch IPS; 3840 × 2160 | Up to 60Hz; DisplayPort 1.2 or HDMI 2.0 | Adaptive-Sync; AMD FreeSync; NVIDIA certification not established here | 60Hz ceiling and no stand height adjustment |
1. ASUS TUF Gaming VG27AQ: best starting point for 1440p
The VG27AQ gives you a useful middle ground between the two other resolutions in this comparison. Its 2560 × 1440 IPS panel has more pixels than 1080p without moving to the much larger 4K image. ASUS explicitly certifies it as G-SYNC Compatible. The stand also supplies height adjustment, swivel, pivot and tilt, which makes it the most flexible desk fit of these three.
Use a direct DisplayPort connection for its maximum 165Hz mode. The official specification lists one DisplayPort 1.2 and two HDMI 2.0 inputs, with HDMI capped at 144Hz. The manual identifies overclocking as DisplayPort-only and warns that it can cause flicker; lower the maximum refresh setting if that happens.
Pros: 1440p resolution, documented G-SYNC Compatible certification and a stand with 130mm of height adjustment. Cons: the headline 165Hz requires the overclocked mode, and HDMI does not reach it. Buy it for these documented features rather than assuming the advertised response-time figure measures total input lag or proves blur-free performance.

2. ASUS TUF Gaming VG249Q3A: best fit for a smaller 1080p setup
The black VG249Q3A has a 23.8-inch IPS screen, 1920 × 1080 resolution and a maximum 180Hz refresh rate. It is the compact choice here, and its lower native pixel count is a reason to consider it when you want to reduce the rendering workload compared with 1440p or 4K. That does not establish a particular FPS result in any game.
ASUS lists Adaptive-Sync and AMD FreeSync Premium for this exact model. Those labels should not be silently upgraded to NVIDIA G-SYNC Compatible certification. An RTX 3070 can connect through its DisplayPort or HDMI inputs, but if validated NVIDIA VRR is a buying requirement, the VG27AQ is the clearer selection in this shortlist. See the VG249Q3A specifications for the exact black model.
Pros: a smaller screen, 180Hz maximum refresh and two HDMI 2.0 inputs alongside DisplayPort 1.2. Cons: the supplied stand tilts but has no height adjustment, and 1080p provides fewer pixels for detailed desktop work. Its 100 × 100mm VESA mounting pattern offers an alternative if you choose a suitable arm.
3. ASUS TUF Gaming VG289Q1A: best fit for a 4K work-first desk
Choose the VG289Q1A when desktop detail and a 3840 × 2160 workspace are higher priorities than a high refresh ceiling. Its 28-inch IPS panel reaches 60Hz, so it is a different proposition from the two faster displays above. A 4K screen can still be useful with an RTX 3070 for work and media, while demanding games may require lower settings or a lower rendering resolution.
The VG289Q1A specification lists DisplayPort 1.2, two HDMI 2.0 inputs and Adaptive-Sync/FreeSync. NVIDIA certification is not established by that page. Treat VRR operation with your NVIDIA setup as something to verify, not a guaranteed feature of every cable and mode combination. The RTX 3070’s HDMI 2.1 capability does not turn this 60Hz monitor into a 120Hz model.
Pros: the highest native pixel count in this comparison, a 28-inch screen and both DisplayPort and HDMI connections. Cons: 60Hz limits its appeal for players prioritizing fast refresh, and the stand offers tilt and swivel but no height adjustment. Choose a faster model if high-refresh gaming is the main reason for the purchase.
What to check before connecting an RTX 3070
NVIDIA specifies DisplayPort 1.4a and HDMI 2.1 capabilities for its reference design. All three monitors here have earlier DisplayPort 1.2 and HDMI 2.0 inputs, so the selected monitor’s supported modes remain the limit. Connect the monitor directly to the graphics card, choose the correct input, and use a cable suitable for the intended resolution and refresh. Check your card maker’s page if the connector layout differs from the reference board.
Enable the monitor’s adaptive-refresh function where required, then follow NVIDIA’s G-SYNC setup instructions. NVIDIA distinguishes validated displays from unvalidated VRR models that can be tested through the control panel. A visible checkbox does not itself establish that a display is certified or that every mode will behave correctly.
For native-resolution rendering, 1080p contains about 2.1 million pixels, 1440p about 3.7 million and 4K about 8.3 million. Those counts explain the workload tradeoff, but FPS does not scale by a fixed ratio. Check results for the games and settings you actually use before paying for a refresh ceiling your system may rarely approach.
Frequently asked questions
Is 1440p a sensible choice for an RTX 3070?
It is the starting point in this comparison because the VG27AQ pairs 1440p with a high refresh ceiling and documented NVIDIA VRR support. That recommendation is a feature-based fit, not a claim that every game runs at 165 FPS. Adjust quality settings to your games and preferred frame rate.
Can an RTX 3070 connect to a 4K monitor?
Yes. NVIDIA documents display-output capabilities beyond 4K at 60Hz. That establishes signal support, not game-rendering performance. The VG289Q1A itself is limited to 60Hz, and your usable mode also depends on the cable and selected input.
Should I use DisplayPort or HDMI?
For the VG27AQ’s 165Hz maximum, use DisplayPort and enable its overclocked mode; HDMI tops out at 144Hz. The VG249Q3A lists up to 180Hz through either input type, while the VG289Q1A is a 60Hz display. Check VRR separately from the maximum refresh rate.
Does FreeSync guarantee G-SYNC Compatible certification?
No. NVIDIA’s setup guidance explicitly distinguishes validated G-SYNC Compatible models from unvalidated VRR displays. In this shortlist, ASUS lists G-SYNC Compatible certification for the VG27AQ; the other two are identified by their documented Adaptive-Sync and FreeSync support.
Why am I seeing only 60Hz after connecting a faster monitor?
Check the selected input, cable and the refresh rate chosen in the computer’s display settings. The VG27AQ also needs its DisplayPort overclock setting for 165Hz. If an overclocked mode flickers, use a lower supported refresh rate as ASUS recommends. A supported high-refresh signal still does not make the GPU render every game at that rate.
