DH436 display adjustment and maintenance
DH436 supports pixel-level brightness/chromaticity calibration, quick bright/dark-line adjustment, independent RGB Gamma and 3D functions. Mapping and a prestored image help with screen setup. Listed maintenance features include temperature and voltage monitoring, cabinet LCD support, error monitoring, firmware/configuration readback, loop backup, configuration dual backup and program dual backup.
The original listing identifies DH436 as RoHS compliant. It leaves the monitoring-card connection and light-board Flash fields blank; those two capabilities are not confirmed here.
DH3208 and MRV432
Both models are described with pixel-level brightness/chromaticity calibration, quick bright/dark-line adjustment, 3D, independent RGB Gamma and 90-degree image rotation. Their listed hardware designs address EMC compatibility. The matching connector count does not establish that the cards are interchangeable in an existing cabinet.
