| Host compatibility | Video output, supported resolution and refresh rate, connector type, and any required adapters. | Match the monitor’s supported input modes to the industrial PC’s documented output modes. Check the full signal path, including adapters and cable length. | Host and monitor manuals; supported timing lists; connector and adapter specifications. | A mismatch can require adapters, configuration work, or replacement hardware. |
| Image and viewing requirements | Screen size, native resolution, brightness, contrast, viewing angle, and ambient-light conditions. | Choose resolution and brightness for the viewing distance, interface layout, and lighting at the installation point. Confirm readability in the actual environment. | Published display specifications and an on-site or representative-environment viewing test. | Inadequate visibility can increase operator error and reduce productivity. |
| Touch compatibility | Touch technology, operating-system support, driver availability, USB or serial connection, and glove or moisture requirements. | Test the complete host-and-monitor setup with the intended operating system, application, gloves, and cleaning routine. Confirm whether touch input is needed at all. | Driver and operating-system compatibility information; touch interface specifications; application test results. | Additional drivers, integration, or touch-related maintenance can increase lifecycle cost. |
| Mounting and installation | Mounting pattern, monitor dimensions, weight, cable clearance, orientation, and enclosure or panel cutout requirements. | Check the monitor’s mechanical drawing against the panel, arm, or enclosure. Confirm that the installation provides required ventilation and service access. | Dimensioned drawings, mounting-hole pattern, installation instructions, and load limits for the mounting hardware. | Installation changes can add labor, brackets, machining, and downtime. |
| Environmental suitability | Operating and storage temperature, humidity limits, vibration tolerance, ingress protection, and front-panel sealing. | Compare the installation conditions with the specified limits. Treat an IP rating as applying only to the stated configuration and protected area; verify the complete installed assembly. | Environmental specifications and test documentation; applicable enclosure or front-panel IP rating under IEC 60529. | Unsuitable environmental protection can lead to failures, cleaning restrictions, and unplanned replacement. |
| Electromagnetic compatibility | Emissions and immunity requirements for the intended industrial environment. | Confirm the applicable requirements for the product and destination market. Industrial immunity and emissions standards may include IEC 61000-6-2 and IEC 61000-6-4 where applicable. | Declaration of conformity and relevant test reports for the exact model and configuration. | Insufficient evidence or performance can create compliance risk, interference, or commissioning delays. |
| Electrical and market compliance | Power input, grounding, safety documentation, and regulatory requirements in each country of use. | Verify input voltage and power-supply requirements, then confirm which safety and regulatory approvals apply to the finished system and its market. | Product label, safety documentation, declarations, and approvals applicable to the destination market. | Missing or unsuitable documentation may delay procurement, installation, or market access. |
| Reliability and serviceability | Specified operating life, backlight or panel service information, warranty terms, repair options, and replacement availability. | Compare documented service terms and the practical replacement process. Do not treat a stated component life as a guaranteed service life for the complete monitor. | Warranty and service conditions; lifecycle or reliability statements; spare-part and replacement policy. | Longer repair lead times can increase downtime and spare-inventory requirements. |
| Energy cost | Typical operating power, operating hours, and local electricity price. | Estimate annual energy use as: power in watts × operating hours per day × operating days per year ÷ 1,000. Multiply kWh by the applicable electricity rate. | Power-consumption specification and the site’s operating schedule and electricity rate. | Energy cost accumulates over the service period; compare like-for-like operating conditions. |
| Total cost of ownership (TCO) | Purchase price, integration, mounting, cabling, energy, maintenance, downtime, replacement, and disposal costs. | Use the same service period and operating assumptions for each option. TCO = purchase + integration + energy + maintenance + downtime + replacement − residual value, where applicable. | Supplier quotations, internal labor estimates, energy assumptions, maintenance records, and downtime-cost methodology. | A lower purchase price may not result in a lower lifecycle cost if integration, service, or downtime costs are higher. |
