Not absolutely sure but I found this...
"I had one for a day. It's not the one displayed in the picture (that's actually a Hitachi 22LD4200, made by Vestel) but is in fact identical to the Techwood 17" LCD at Curry's. The Hitachi 17LD4220 is identical to this, with a slightly restyled front. Specs-wise, it's 1280x768 (15:9), 25ms response, 400:1 contrast, 140H 110V viewing angle, 2 RGB SCARTs"
A user manual for the Hitachi model mentioned can be got freely from this link...

You have to type in a code number that you see on the screen - it looks quite safe. I hope it helps...
Good luck...
