Every guide lives in one of five topic hubs, so you can go straight to the area that matches your question. Each hub starts with the basics and builds up to more specific questions. The blog collects wider reads that do not fit neatly into a single hub.
What refresh rate, response time, contrast, gamma and adaptive sync really mean, and how to set them.
Connect and arrange anything from a single screen to a six-monitor desk, with the right cables and settings.
VESA patterns, arms, stands, safe transport and what to do with monitors you no longer need.
Step-by-step fixes for no signal, dead pixels, ghost images, flicker and other common monitor faults.
Honest advice on size, resolution, refresh rate, panel type and brands before you spend your money.
Wider reads on monitor topics that go beyond a single how-to question.
Recently published and updated guides from across the knowledge base, each one dated so you know how current it is. New guides appear here first.
Yes. KTC is the own brand of a listed Chinese display maker founded in 1995, selling fast, Mini LED and OLED monitors with 3 years of cover on most.
Yes, for value. Koorui is HKC's budget monitor brand, selling fast IPS, curved VA and Mini LED screens cheaply, but US panel coverage is only one year.
IPS glow is a corner haze that shifts as you move your head. Backlight bleed stays fixed. Glow is normal on IPS panels; strong bleed is a return case.
LCD screen bleeding is backlight leaking at the edges. A little is normal on most LCDs. If you can see it in a lit room, return or exchange the monitor.
Vertical lines on a laptop screen come from a loose display cable, a failing panel or a graphics driver. Plug in an external monitor first to tell which.
A faint white line on a monitor is usually one row or column of pixels misbehaving. If it shows in the monitor's self-test, the panel is at fault.
Yes. Acer is a good monitor brand, strongest on value gaming with Nitro and fast flagships with Predator, backed by a three-year US limited warranty.
Two monitors side by side give cheap extra space for multitasking, but cost desk room, neck turning and a center bezel. Here is when it pays off.
To play 16:9 games on an ultrawide, set GPU or monitor scaling to keep the aspect ratio. You get a sharp, undistorted picture with black side bars.
These six guides answer the questions most people ask first. Read them in any order: each one stands on its own, starts with a direct answer and links to deeper detail when you need it.
Stop screen tearing and stutter with a setting most gaming monitors already support.

Spec sheets are full of numbers that look precise but are easy to misread. Here is what the specs that matter most actually tell you, and where to go for the full detail.
Resolution is the number of pixels on the screen: 1920 x 1080 (1080p), 2560 x 1440 (1440p) or 3840 x 2160 (4K). What your eyes notice is pixel density, so the same resolution looks sharper on a smaller panel. You can also run a lower resolution on a sharper screen, and our guide to playing 1440p on a 4K monitor shows how to do it cleanly.
Refresh rate, measured in hertz (Hz), is how many times per second the screen redraws. A higher rate such as 144Hz or 165Hz makes motion smoother, as long as your graphics card can supply enough frames.
Response time comes in two forms. GtG (gray-to-gray) measures how quickly a pixel changes color, which overdrive speeds up. MPRT measures how long each frame stays visible to your eye, and a very low MPRT figure usually depends on backlight strobing.
Panel type shapes contrast, viewing angles and price. IPS panels are known for consistent color, VA panels for deeper blacks, and OLED for lighting each pixel individually, which is part of why OLED costs more.
HDR and contrast describe the gap between the darkest and brightest parts of an image. Treat headline figures with care: a dynamic contrast ratio comes from adjusting the backlight, not from the panel itself.
Adaptive sync lets the monitor match its refresh rate to your graphics card, which removes tearing and reduces stutter. FreeSync, G-Sync and VRR are versions of the same idea, and a FreeSync monitor works with Nvidia cards too.
Once a monitor is on your desk, the settings matter as much as the spec sheet. A quick color accuracy test and the right gamma setting often improve the picture more than any upgrade. For running costs, see how much power a monitor uses.
A good monitor setup starts with ports and cables, then moves on to layout and mounting. The jump from one screen to several changes what matters most.
Single monitor: match a cable to the ports on your computer and screen, power both on and select the right input. Our monitor connection guide covers cable choice and what to do when the screen stays black.
Dual monitors: most desktops can run two screens straight from the graphics card. If your laptop is short on ports, a docking station for dual monitors fills the gap. A shared arm keeps both screens level, as long as your monitors are compatible.
Triple monitors: almost any modern graphics card can drive three displays for everyday work. The card only becomes the limit when you want to game across all three, which our triple monitor graphics card guide explains.
Four to six screens: layout and graphics hardware decide whether a large rig works. Start with the quadruple monitor setup guide, then read the 6 screen monitor setup guide. Most consumer Nvidia cards top out at four screens, while many AMD cards can drive six.
Whatever the count, mounting matters. The VESA mount guide explains hole patterns, mount types and safe installation, so every screen sits at the right height and distance.
Using a desk-mounted stand with speakers or a turntable nearby? Read whether isolation pads on monitor stands are worth it.
Multi-monitor desks also bring smaller everyday questions. We cover how to print screen on only one monitor, what to do when Twitch freezes on a second monitor in Chrome, and how to connect a phone to a monitor for a bigger view.
Moving or retiring a monitor? Learn how to transport computer monitors without cracking the screen, whether Goodwill takes computer monitors, and what to do with old monitors.
Most monitor faults have a simple cause, and many take minutes to fix. Work through the likely cause before you change settings or order a replacement. Find your symptom below, try the first fix, then open the full guide if the problem persists.
| Problem | Likely cause | First fix | Full guide |
|---|---|---|---|
| No Signal message | Loose cable, wrong input or no video from the PC | Reseat the cable at both ends and select the correct input. | No signal fix |
| Cable Not Connected warning | No video signal reaching the selected input | Check the input source and plug into the graphics card port. | Cable not connected fix |
| Dot that never changes | Dead pixel or stuck subpixel | Run a full-screen color test to tell dead from stuck. | Dead pixel guide |
| Faint ghost image | Temporary image retention, rarely true burn-in | Show changing content for a while, then check again. | Screen burn guide |
| Speck that will not wipe off | Dust or a tiny insect inside the panel layers | Confirm it sits under the glass before opening anything. | Dust under screen fix |
| Flicker, lines or blur | Failing cable, display driver or wrong settings | Swap the cable, then update your graphics driver. | Screen issues guide |
Seeing a fine grid or a shimmering pattern instead? Read about the screen door effect and pixel inversion. If a fix does not hold, our monitor repair guide explains when it is time to send a screen in. Brand-specific guides, such as AOC dead pixel warranty claims and the HP 1740 manual, cover the details for particular models.
The right monitor depends on three things working together: screen size, resolution and how far you sit from the screen. For most people, 27 inches at 1440p is the sweet spot, sharp enough for work and play without demanding a top-end graphics card.
Go smaller if your desk is shallow or you play competitive shooters, where a 24 to 25 inch screen keeps the whole image in view. That is why many pros use 24.5 inches. Go up to 32 inches at 4K if you can sit about 80 centimetres back, and see our gaming monitor size guide for the trade-offs.
Resolution should always match the size. Our 4K vs 1080p comparison shows where extra pixels pay off and where 1080p is still enough. For refresh rate, a 165Hz monitor gives most gamers nearly all the benefit of high-refresh play.
Panel technology drives price more than almost anything else. Read why OLED monitors are expensive before deciding whether the upgrade is worth it. If a big TV looks tempting, check the downsides of using a TV as a monitor first.
Weighing up a lesser-known brand? Our honest assessments of Sceptre, Titan Army and Z-Edge look at where each one offers real value and where it cuts corners. If you work in 3D, read whether you need a 4K monitor for 3D work before paying for the extra pixels.
Buying for someone with low vision? Our guide to monitors for visually impaired users covers the features that make the biggest difference.
| Size | Best resolution | Typical viewing distance | Best for |
|---|---|---|---|
| 24in | 1080p (1920 x 1080) | About 60 cm | Competitive gaming, shallow desks and tighter budgets |
| 27in | 1440p (2560 x 1440), or 4K for extra sharpness | About 70 cm | All-round use: work, gaming and media |
| 32in | 4K (3840 x 2160) | About 80 cm | Single-player games, creative work and detailed content |
| 34in ultrawide | 3440 x 1440 | About 80 cm | Wide workspaces, racing and flight sims |
Distances are eye-to-screen and approximate. As a rule, each step up in size needs about 10 centimetres more room to feel the same.
