Well, both the packaging and literature state that the Spectrum video card will support multiple resolutions. This feature will be available in the next release of the firmware (as well as NTSC). For those that do _not_ have the Spectrum B11 ROM, please contact your dealer and make arrangements for an exchange with SuperMac. 2. The Horizontal Frequency is 48.190 KHz The Vertical Frequency is 59.28 Hz The Pixel Clock is 64.000 MHz 3. Any "verical artifact" is probably a result of Convergence which has not been properly adjusted. There is a convergence test that the "user" can use by selecting the Monitor cdev from the Control Panel and then using the V-Stat (Vertical Static Convergence Control), H-Stat (Horizontal Static Convergence Control), and the V-Cent (Vertical Centering Control). Once done, the convergence will be properly adjusted. If not, contact your dealer for proper adjustments. Also, any "Moiree" pattern can be eliminated by using Apple's new System 4.2 General cdev which allow you to change the color of your desktop pattern. I hope that this answers you questions. I'm suprised by your comment that SuperMac couldn't give you any answers. Could you send me E-Mail and let me know who you spoke to and when you called. I'd be more than happy to check this out.
