iiyama T2238MSC-B1 21.5-inch Touch monitor

Buying checks

• Protection rating: IPX1 applies only to the front face. It is not a dust-protection classification, whole-enclosure rating or guarantee of outdoor or waterproof use.
• Permitted mounting positions: Landscape, either portrait rotation and face-up are shown as available; inverted landscape is not available. Rotating the image for portrait requires appropriate support/settings on the connected video card. Physical mounting alone does not rotate content.
• Mounting and enclosure cooling: Use a wall or built-in case strong enough for the display and mount. The T2238 uses four M4 VESA screws with 7 mm chassis insertion (L), allowing separately for bracket/plate thickness; 7 mm is not total screw length. The T2438 9 mm recipe and the separate eight M4 holes at 7.25 mm depth are not this four-hole VESA recipe. Overlong screws can contact electrical parts and cause shock or damage. Enclosures need cooling fans/vents within operating temperature limits. Keep at least 10 cm wall clearance and rear vents clear when removing the stand; do not rest the enclosure on its back/side or soft material and block ventilation.
• Touch modes and host compatibility: The revision-C table marks digitizer and gestures supported for Windows 7/8/8.1/10/11 but not its separate mouse column. Vista supports digitizer only; XP supports mouse only. Linux mouse support depends on the OS version, not unconditional digitizer or gestures. Mac OS/OS X and Android have no supported modes in this matrix; unlisted versions are not supported by the table. Gestures depend on the application. Dual-screen Tablet PC setup recognises two displays but touch operates on only one at a time, not simultaneously across both.
• Video, USB and safe connections: Connect the external computer through HDMI or DisplayPort and a separate USB upstream cable for touch. The manual specifies USB 3.2 Gen 1 at 5 Gbps, one upstream Type B and two downstream Type A connectors; downstream is rated 5 V/900 mA. These are not USB-C video, laptop charging or an included computer. Switch host/display off before connecting, connect power to the monitor before supply, then switch on. Use the correct signal cables: wrong connections can damage equipment. The manual requires protective earth, a nearby accessible socket and a 120/240 V, 20 A maximum building circuit breaker; excessive headphone volume can damage hearing. Confirm the separate 3.5 mm port direction before relying on it.
• Included cables and stand: The package lists the mains, HDMI and USB cables, stand neck/base with their screws, screwdriver, cable cover and Safety/Quick Start Guides. DisplayPort cable is not included; no PC or driver disc is established by this inventory. Use an approved power cable at least H05VVF, 3G, 0.75 mm². The manual excludes guarantees/warranties for problems or damage caused by a power cable not supplied by iiyama.
• Cleaning and disinfection: Switch off and unplug before care. Use a soft clean dry cloth; for a dirty cabinet, use very dilute mild detergent on a tightly wrung cloth followed immediately by a dry cloth. Do not spray alcohol/disinfectants or use alcohol/disinfectant wipes: cabinet cracking/discolouration, touch-surface damage and component deterioration can result. Avoid strong solvents, glass cleaner, abrasives, cleaning sheets and hard rubbing. Dry water drops promptly; prolonged rubber/plastic contact can damage the cabinet finish. Liquid or foreign-material entry requires immediate unplugging and dealer/manufacturer service. The manual recommends disinfecting hands away from the display and avoiding frequent alcohol disinfection; understand all cautions if it is unavoidable. It does not establish the separate water/IPA touchscreen-cleaning recipe used by some other models.
• Location and operating schedule: Avoid direct sun, sudden temperature changes and humid, dusty or smoky locations. Route cables safely and do not place heavy objects on the display. This product is not specifically designed for 24/7 use in all environments; the front-protection rating is not permission for outdoor use or blocked ventilation.
• Measurement and environmental limits: Typical brightness through touch is 525 cd/m²; 600 cd/m² is bare-panel brightness and 270 cd/m² is the default energy-saving setting. The 1000:1 contrast is measured through touch. Dimensions are 512.5 × 353.5 × 239.5 mm in the stated stand configuration; 6.8 kg is net product weight, not the separate 8.1 kg packaged weight. Typical 17 W excludes connected USB devices; standby is at most 1.5 W and off at most 0.3 W. Operate at 5–35°C and 10–80% humidity, non-condensing. The −20–60°C and 10–90% figures are storage limits, not a wider operating range.
• Response-time setting: The manual lists 14 ms typical response. Its 5 ms grey-to-grey figure applies only with Overdrive set to 5, not as an unconditional response-time rating.
• Confirm the 3.5 mm audio connection: The manufacturer's manual describes a headphone output, while its datasheet and product page describe an audio input. Confirm the connector direction before specifying an analogue audio connection or equipment that depends on this port.
