Summary

This is a barebones consumer model from 1987. Opening it up reveals a Hitachi HA11480 jungle chip, which does not have any support for s-video or RGB. Even if it had a better jungle, the tube in this is one of the worst I have ever seen from NEC. It's one of their "made in america" tubes and I would estimate it to be no higher than 300 TVL, which is far too low for 26". The 110 degree deflection angle makes it even worse. This TV also has one of the worst comb filters I've ever seen... For these reasons I recommend avoiding this TV, even if its free. The parts inside (NEC uPC1377C for example) are worth more than the CRT is :)

From my understanding there is another similar model in the CT series which has RGB input but has an equally poor-quality tube. Seems the NEC CT series can ultimately be avoided by anyone seeking a quality vintage consumer monitor. The DM series used much higher TVL professional-grade tubes.
