(Note)

- In simultaneous mode, the CRT Vertical & Horizontal refresh rate is 60Hz & 31.5khz respectively, which is same timing as TFT LCD.

- If using either high color or true color mode PC Magazine Graphic WinMark benchmark performance is slower than using mode 30(256 color).

- SVGA modes are supported with Windows 3.x only, using a special video driver.
