Explainers
These 9 are the arguments that come back month after month before anyone buys a monitor, and every one of them leads with a short answer.
Yes at 27 inches, and it is not close: 4K there works out to 68 pixels per degree of vision at a normal desk distance, against 46 for 1440p. Sixty is the point where 20/20 eyesight stops resolving individual pixels, so one of those panels has a visible grid and the other does not. The catch is that 4K at high refresh rates costs far more GPU than 1440p does, which is a separate decision from whether you can see it.
Read the full answer →Because subpixel antialiasing assumes the three colour dots in each pixel sit in a vertical RGB stripe, and OLED monitors do not use one: QD-OLED arranges them in a triangle, and WOLED adds a white subpixel. Windows renders the edges of small glyphs on the wrong-coloured dots, which shows as a faint red or green rim. A higher-resolution OLED hides it, macOS mostly sidesteps it, and no setting fixes it outright.
Read the full answer →Worried enough to check the warranty before buying, and not so worried that you avoid the panel. Every OLED monitor in this catalog carries at least two years of cover that explicitly names burn-in, and most carry three. The exposure that matters is hours of static bright interface at high brightness — a taskbar, a spreadsheet grid, a stream overlay — not gaming.
Read the full answer →Because your monitor is almost certainly accepting an HDR signal it cannot display. DisplayHDR 400 requires 400 nits peak and permits an edge-lit backlight with zero dimming zones, so the panel switches to an HDR tone curve without gaining any contrast — and a tone curve designed for a display that can hit 1,000 nits looks grey on one that cannot. Real HDR needs per-pixel emission or a backlight divided into hundreds of zones.
Read the full answer →Not pointless, but sharply diminishing. A frame sits on screen for 16.7 ms at 60 Hz, 6.9 at 144, 4.2 at 240 and 2.1 at 480 — each doubling of the refresh rate halves it, and the absolute saving collapses as it goes. The perceptual jumps shrink accordingly, and past 240 the limiting factor is usually the panel's own pixel response and your frame rate rather than the refresh rate. An OLED at 240 Hz looks clearer in motion than an LCD at 360.
Read the full answer →Check the wattage against the laptop's own charger, not against the phrase "charges your laptop". Sixty-five watts holds a 13-inch ultrabook, 100 covers a 14-inch machine under normal load, and a 16-inch workstation wants 140 to stay charged while its CPU and GPU are both busy. A monitor below that figure will report that it is charging while the battery slowly drains.
Read the full answer →Multiply width by height by refresh rate by bits per pixel, add about 20% for blanking overhead, and compare the result against the port's usable data rate: 14.4 Gbps for HDMI 2.0, 42.67 for HDMI 2.1, 25.92 for DisplayPort 1.4, and up to 77.37 for DisplayPort 2.1 UHBR20. If the panel needs more than the port has, either DSC compression makes up the gap or the monitor quietly runs at 8 bits per channel instead.
Read the full answer →macOS renders the interface at exactly twice the logical size and then scales the whole frame down, which is crisp at 2× and slightly soft at anything else. Windows scales each application by whatever fraction you ask for, which is sharp at any factor but leaves older applications blurry or tiny. That is why 27-inch 4K — 163 PPI, an awkward 1.5× — is fine on Windows and divisive on a Mac, where 218-PPI 5K lands on an exact 2×.
Read the full answer →Two monitors if you need vertical space or want one of them in portrait; one ultrawide if you spend the day in windows that span the middle of the screen, or if a single cable to a laptop matters. A 34-inch 3440 × 1440 ultrawide is 1,440 pixels tall: exactly as tall as the 27-inch 1440p panel it replaces, and 720 lines shorter than a 4K one. Vertical is the dimension people miss.
