Are you sure on the model number.
Eizo Nanao original numbering system was MS### SU
- the SU I believe meant made/designed for Sega USA
- MS Multi Scan
the # after MS ,,, for example MS9 was just sequential in the series as MS9 followed MS8
- 29 is the CRT size, a little misleading as it means the measurement diagonally to the outside edge of the glass, where as North American trade laws forced most companies to indicate the diagonal dimension of the actual li Phosphor.
The MS929 SU was really a 27inch viewable= 27V.
Hope this helps, If I am wrong, sorry but the right model number is critical.
