Description

LCD Upgrade Kit for 14-inch Hitachi Seiki Multi LX3 CRT, Hitachi 20S2, Hitachi 20SII, Panasonic CRT. Full cable kit for complete conversion.

12 inch LCDThe benefits of buying Hitachi Seiki LCD from Monitech are substantial. We offer an upgrade over the OEM; the CRT that your unit currently has is very old technology, nearing the end of its life cycle. Our LCD monitors are current technology with a very long life expectancy; over 50 000 hours. We offer our newer technology at a much lower cost than the OEM charges for their aging displays. In addition to the monetary savings and enhanced products, we have very quick lead times; we can often send out the product the same day an order is placed!

We have a “How To” video for Hitachi Seiki Multi LX3 LCD upgrade kit
