What to check before you choose
For a display, balance image quality with the computer or console driving it. Resolution, refresh rate and HDR only help when the source and connection support them.
Panel and lightingCompare contrast, brightness, reflections and local dimming for your room and content.
Resolution and refreshMake sure your GPU or console can deliver the target resolution and frame rate.
Ports and ergonomicsCheck HDMI or DisplayPort versions, stand adjustment and USB-C power if you use a laptop.
A few details that can change your decision

Backlight BloomingBlooming (haloing) is the soft glow around bright objects on dark backgrounds on LCD TVs and monitors that use local dimming . Zones cannot match pixel-level light control, so stars, subtitles, and game HUDs can light a larger patch than they should. OLED largely avoids classic backlight bloom because pixBlack Frame InsertionBlack frame insertion (BFI) and related backlight strobing (ULMB-class) darken between frames to reduce sample-and-hold blur. Motion looks clearer; brightness drops and some people notice flicker. Competitive monitor feature lists tuck BFI next to Hz. This explainer is based on how black frame insertion (Burn-In (OLED)Burn-in (also called image retention that becomes permanent) is when a display shows a lasting ghost of static UI — logos, HUDs, taskbars — after that content moves on. It worries OLED buyers most because each pixel ages with use; temporary retention can also appear and then fade. You will see burn-in FAQ

Chroma SubsamplingChroma subsampling (4:4:4, 4:2:2, 4:2:0) describes how much color detail a video signal keeps versus brightness detail. 4:4:4 keeps full color resolution — best for sharp desktop text and UI. 4:2:0 throws away more chroma — standard for most movies and streams where it is hard to notice. You will meet theColor GamutColor gamut is the range of colors a display can show. Specs usually compare coverage of standards like sRGB (everyday web/SDR) and DCI-P3 (wider cinema / HDR-oriented). Bigger coverage can mean richer color — only if content and calibration use that range. You will see “% sRGB,” “% DCI-P3,” Adobe RGB, ReContrast RatioContrast ratio is how bright a display’s whites are relative to its blacks — often written like 1000:1 or “infinite” on OLED. Higher usable contrast usually means punchier images; a huge marketing number alone does not guarantee great real-scene blacks. You will see static / dynamic / ANSI contrast, “mega

Delta EDelta E (ΔE) measures how far a displayed color is from the intended target. Lower average Delta E usually means more accurate color — often marketed as “ΔE < 2” for creator monitors. It is an accuracy score, not a brightness or gamut-size score. You will see factory calibration reports, average ΔE, maDisplay Viewing AngleViewing angle describes how much brightness/color shifts when you are not centered. IPS and OLED generally hold up better off-angle than many VA panels, which can look washed or tinted from the side. Family couch TVs and ultrawide desks make angles a real purchase factor. This explainer is based on how viDisplayPortDisplayPort (DP) is a digital video link common on PC monitors and graphics cards. It often unlocks higher refresh rates and resolutions on gaming and creator displays, and it carries VRR standards like Adaptive-Sync. It is not the same connector as HDMI — many TVs still prefer HDMI. You will see DisplayPDolby VisionDolby Vision is a dynamic HDR format that can adjust brightness and tone-mapping instructions scene-by-scene (or frame-by-frame) using metadata. On TVs and some monitors it often looks more consistent than static HDR10 — but only when the display, app/player, and title all support Dolby Vision. You will s

HDMI 2.0HDMI 2.0 is the HDMI generation that made 4K at 60 Hz with HDR mainstream (about 18 Gbps ceiling). It is still enough for many TVs and streaming setups. HDMI 2.1 raises bandwidth for 4K high-Hz gaming and richer optional features — you only need that path when your source and display actually use it. YouHDMI 2.1HDMI 2.1 is a newer HDMI generation that raises bandwidth so one cable can carry higher resolutions, higher refresh rates , and features like VRR , ALLM, and eARC more cleanly than older HDMI 2.0 links. The version number on the box is a capability ceiling — not proof every port unlocks 4K 120 Hz. You wilHDRHDR (High Dynamic Range) aims for brighter highlights and wider contrast than SDR, when content is mastered for HDR and the display can use it. An HDR logo is a capability claim, not a promise every stream looks cinematic. HDR10, HDR10+, Dolby Vision, and HLG differ; brightness and tone mapping vary. GadgHDR10+HDR10+ is a dynamic HDR format (royalty-light relative to some rivals) that adds scene-by-scene metadata on top of the HDR10 base. Like Dolby Vision , it aims for smarter tone mapping than static HDR10 — when the TV, player/app, and title all speak HDR10+. You will see HDR10+ on many Samsung and Amazon ecHLGHLG (Hybrid Log-Gamma) is an HDR transfer standard designed so the same signal can look acceptable on SDR TVs and better on HDR TVs — popular for live broadcast and some streaming/sports deliveries.

Matte vs GlossyMatte vs glossy screen coatings trade reflections against perceived sharpness and “pop.” Matte / anti-glare scatters room light so you can work near windows with fewer mirror-like reflections, sometimes with a slightly grainier or less “wet” look. Glossy coatings look deeper and sharper in controlled lighMini-LEDMini-LED is an LCD backlight made of thousands of tiny LEDs grouped into dimming zones. More, smaller lights let the set brighten highlights and darken nearby areas better than old edge-lit LCDs — closer to “HDR punch” without being a self-emissive OLED .

PPIPPI (pixels per inch) is how densely pixels are packed on a screen. Higher PPI usually means sharper text and less visible pixel structure at a given viewing distance — but it is not the same as resolution, and chasing max PPI past what you can see wastes money and GPU power. You will see PPI (or “pixel dPWM FlickerPWM flicker (pulse-width modulation) is a way some displays dim the backlight or OLED by switching light on and off rapidly. At lower brightness the “off” gaps grow — sensitive eyes can notice flicker, fatigue, or headaches even when the screen looks steady to others. You will see PWM, DC dimming, hybrid

QD-OLEDQD-OLED is an OLED panel that uses blue OLED emitters plus a quantum-dot color converter layer to make red and green. Versus classic white-OLED (WOLED) TVs, QD-OLED often pushes wider color and different brightness/viewing behavior — still a self-emissive OLED with deep blacks, not an LCD “QLED.” You willQuantum Dot (QLED)Quantum dots are tiny nanocrystals that convert light into very pure colors. On most TVs marketed as QLED , they sit in an LCD stack with a backlight (often LED or mini-LED ) — improving color, not turning the set into OLED. QD-OLED is the exception that uses quantum dots inside a true OLED panel. You wil

Refresh RateRefresh rate is how many times per second a display can redraw the image, in hertz (Hz) . A 60 Hz panel updates up to 60 times per second; 144 Hz and 240 Hz can update faster when games or devices deliver enough frames. Higher Hz is a ceiling, not a free FPS boost. FPS is what the GPU produces; Hz is whatResponse TimeResponse time on monitors is how fast pixels can change color, usually marketed in milliseconds.

Ultrawide Aspect RatioAn ultrawide aspect ratio (commonly 21:9, sometimes 32:9 super-ultrawide) spans wider than 16:9 for immersion and timeline/spreadsheet space.
