I read that the Dell 2320L was supposed to sync down to Amiga timings but it doesn't work.
"Horizontal scan range 30 kHz to 83 kHz"
Which Amiga and hardware add-ons? For classics, this scan range will not work for the 500 or 2000 that run at very low 15.7kHz unless they have a scan doubler or video card added. It should work fine with a stock 3000's vga output and a 4000 with a vga adapter and the proper video mode selected.
