Then check measured pixel response, input lag, variable refresh rate (VRR), and whether the intended connection supports the monitor’s advertised mode. A bigger number on the box does not guarantee a better experience if your system cannot use it.
Start with your games and your system
There is no best resolution-and-refresh-rate combination for every player. Competitive games often reward high frame rates and clear motion; visually detailed games can benefit more from resolution and pixel density. Your graphics hardware, game settings, monitor, and video connection all need to support the mode you intend to use. A high-resolution, high-refresh display cannot show frames your system does not render or a connection cannot carry.
- Competitive and fast-action games: Prioritize a refresh rate your system can feed consistently, then compare motion clarity, pixel response, and input lag.
- Detailed, immersive, or text-heavy games: Consider higher resolution and pixel density, while allowing for the extra rendering load.
- Mixed use: Balance those priorities against screen size, viewing distance, picture characteristics, and budget rather than optimizing one specification in isolation.
What resolution and screen size tell you
Resolution is the number of pixels in the image. At the same screen size, more pixels produce higher pixel density and can show finer detail. RTINGS gives the example of a 27-inch display: 1440p is 109 pixels per inch (PPI), while 4K is 163 PPI. At the same resolution, a 24-inch screen has higher pixel density than a 32-inch screen.
That added detail has a cost: a PC has to render more pixels, which can make it harder to sustain high frame rates. An entry-level PC used mainly for competitive games may be better paired with a lower-resolution display if that helps deliver the frame rate you want. A player focused on detail may prefer higher resolution. Screen size and viewing distance also affect how noticeable pixel density differences are; the PPI examples are comparisons, not universal size recommendations. RTINGS’ gaming monitor buying guide explains these trade-offs.

Refresh rate, frame rate, and frame time
Refresh rate is how many times per second the monitor updates, measured in hertz (Hz). Frame rate is how many frames the PC or console supplies, measured in frames per second (fps). They are related but not interchangeable: the monitor’s maximum refresh rate does not mean the source will deliver that many frames.
A higher refresh rate shortens the time available for each display update and can make motion look smoother, especially in competitive and action games. RTINGS calculates the following frame times as 1,000 divided by the refresh rate:
Rank #2
- QHD Resolution (2560 x 1440) has 1.7 times the pixel density of Full HD for incredibly detailed pinsharp images
- HDR10 provides brighter highlights and nuanced shadow for added depth - making every scene feel more vivid and realistic
- The 180Hz refresh rate minimizes lag for gameplay with ultra-smooth action. Plus, the 1ms response time helps capture your moves in real-time, allowing you to react fast for gaming precision
- AMD FreeSync reduces choppiness, screen lag and image tearing, ensuring that your fast-paced, complex in-game action is stable with minimal stutter
- Ergonomic stand allows for tilt, pivot and height adjustments to maximize gaming comfort
| Refresh rate | Frame time |
|---|---|
| 60 Hz | 16.67 ms |
| 120 Hz | 8.33 ms |
| 144 Hz | 6.94 ms |
| 165 Hz | 6.06 ms |
| 240 Hz | 4.17 ms |
| 360 Hz | 2.78 ms |
| 480 Hz | 2.08 ms |
| 540 Hz | 1.85 ms |
| 720 Hz | 1.39 ms |
These frame-time figures are arithmetic conversions, not measurements of pixel response or input lag. The perceived improvement also depends on the player and game: RTINGS notes that the jump from 60 to 120 Hz is more apparent than the difference between 360 and 480 Hz, but there is no universal point at which everyone stops noticing a change. Its refresh-rate explainer distinguishes refresh rate from source frame rate.
Check the full signal path
Before paying for a high-refresh mode, check that your graphics card or console can produce the intended resolution and frame rate, and that both source and monitor ports have enough bandwidth for the chosen resolution, refresh rate, and color depth. A monitor’s headline maximum may not be available through every input.
Rank #3
- Smooth motion: 240Hz refresh rate and fast 0.5ms response time provide crisp visuals and fluid movement with less input lag.
- Seamless gaming: FreeSync Premium and HDMI VRR eliminate tearing for smooth, responsive PC and console gameplay.
- Fast IPS: Faster 0.5ms response with excellent color accuracy across wide IPS viewing angles.
- Rich color: 99% sRGB color coverage delivers vivid, detailed imagery with strong accuracy.
- Eye comfort: TÜV Rheinland 3‑star certified display lowers blue light while preserving color quality.
For example, RTINGS reports that the Dell Alienware AW3423DWF reaches up to 165 Hz, but its HDMI 2.0 input is limited to 100 Hz at 8-bit or 60 Hz at 10-bit in the setup described by the guide. That is a model-specific example, not a rule for every HDMI 2.0 display. Check the exact monitor’s supported modes and the device and cable connection you plan to use. RTINGS’ buying guide discusses this connection constraint.
Pixel response time is not input lag
Pixel response time describes how quickly a pixel transitions between colors. Slow transitions can leave smearing or blur behind moving objects. Overdrive settings can speed transitions, but overly aggressive overdrive may cause inverse ghosting, also called overshoot. Two monitors with the same refresh rate can therefore differ in motion clarity.

Do not treat a marketing “1 ms” claim as a complete performance result. Results depend on how response is measured, the transitions tested, refresh rate, and overdrive setting. RTINGS’ newer Test Bench 2.0 and later methodology uses Cumulative Absolute Deviation (CAD), which combines response time and overshoot; results from that methodology are not directly comparable with older test benches. Its detailed response-time test description says measured response metrics characterize performance at maximum refresh rate at native resolution.
Input lag is a separate delay: the time the monitor takes to process a received signal and begin displaying the image. Response time describes the pixel transition after that. A monitor can have low input lag but slower pixel transitions, or the reverse. For reaction-based games, compare input lag at the refresh rate and mode you expect to use. RTINGS explains its measurement in its input-lag methodology.

VRR can help with uneven frame rates
Variable refresh rate (VRR) synchronizes the display’s refresh to changing source frame rates, helping reduce screen tearing when performance fluctuates. Common formats include AMD FreeSync, NVIDIA G-SYNC, and HDMI Forum VRR. Confirm that the specific monitor and source support a compatible mode; the presence of a format name alone does not establish compatibility with every device or connection.
VRR can flicker on some monitors during large frame-rate changes, particularly in dark scenes. This is model-level behavior, so look for testing of the display you are considering rather than assuming it will or will not occur. RTINGS’ buying guide covers VRR and its potential trade-offs.
Compare monitors using the mode you will actually play
Compare candidates against your own use, not just their maximum specifications. Use the intended resolution, refresh rate, connection, and system as your reference point.
- Resolution and size: Check native resolution, screen size, and the resulting pixel density.
- Usable refresh rate: Verify the maximum refresh rate at your chosen resolution and through the input you will connect.
- Motion clarity: Look for measured pixel transitions and overshoot at a relevant refresh rate, not only a quoted “1 ms” figure.
- Input lag: Compare results at the refresh rate and mode you plan to use.
- VRR: Check compatibility with your GPU or console, the supported connection, and reported flicker behavior.
- System capability: For a PC, consider the graphics card and port bandwidth; for a console, confirm its output limits and monitor compatibility.
- Room and use: Weigh picture quality, brightness, contrast, screen size, viewing distance, and budget against your priorities.
A high-end 4K, 240 Hz example
The ASUS ROG Swift OLED PG32UCDM Gen3 illustrates what a premium specification combination looks like: RTINGS’ 2026 recommendations page lists a 32-inch QD-OLED panel, 240 Hz maximum refresh rate, and 3840 × 2160 native resolution, and names it its best gaming monitor. Those are product specifications and a recommendation from that page, not a universal fit for every player. A PC must be able to deliver the desired frame rate at 4K, and the connection must support the selected mode. Check the exact listing and regional availability before buying; stock and prices can change. See RTINGS’ 2026 gaming-monitor recommendations.
