It is presented as-is, and there are no guarantees that it will do what you need. Be warned, if you don't have considerable electronics experience you shouldn't attempt this. If you blow your monitor or video card, don't come crying to me. They also have fast drivers for specific software products such as Autocad, 3D Studio and Windows 3.1 etc. All cards support separate sync and composite sync as well as sync on green.
Software comes with the cards to adjust frequency, setup and centering.
This card uses an S3 graphics accelerator. These cards work with all fixed scan monitors including, IBM, Mitsubishi, Hitachi, Sony, Sun, HP, Verticom, DEC, Taxan, Philips, Apollo, Silicon Graphics, Intergraph, Aydin, Amtron, Monotronix, etc. and will replace old boards from, Artist, Number9, Nth, Verticom, Photon, BNW, VMI, Matrox, Metheus, Mirage, Graphax, Imagraph, TAT etc. CL-5434 processors appear to power all of the Photon cards. Cards automatically boot up with a frequency compatible with your monitor. I was also informed of a German manufacturer ELSA that makes similar cards, but I do not know of their address or product range.
