I have been searching for a SVGA/DVI LED multi sync monitor that will work on most if not all Amiga modes. The Acer 246HL is a great 24-inch-wide screen monitor. It works great on my A2000, A1200, A3000DT, A4000 in NTSC mode with default factory settings. It works great in NTSC and DBLNTSC and no flicker modes. In PAL modes monitor horizontal and vertical need to be adjusted to get rid of the black vertical blanking line. I purchased this from a thrift store for $10.00, I am very happy with it. If anyone has a monitor that works for you let me know.
Here are a few screen shots connected to my A4000.
Power requirements are 19v at 2.1 amps (or more) a laptop P/S works great as long it has a positive center pin.
