From the review in the German magazine c't, March -90

	Available resolutions
		640 x 608	60 Hz
		832 x 624	50 Hz
		640 x 480	75 Hz
		704 x 496	71 Hz
		640 x 400	87 Hz

	Mega-ST only (needs the expansion plug)

	Needs TOS 1.2 or later.

	Only in monochrome mode.

	General stuff

		Seems to require a multisynch monitor because of the
		large number of resolutions. I don't know about
		that, what about running with the normal monochrome
		monitor in 704 x 496 mode ?? (This mode only, of
		couse, but still.)

		Made from a Hitachi video controller, and four small
		chips (say three normal TTL chips and one PAL). Works
		by reprogramming the video timing and using a larger
		amount of Atari video memory.

		The name is MegaScreen, the manufacturer is WGR
		ComputerSysteme (no address given in the test, no ads found
		in the magazine).

		Should be usable on all ``well-behaved'' programs....... .
		I can't see how they could make the 640 x 400 mode
		incompatible, as far as placement of video meory goes,
		so I should think that in 640 x 400 mode the ``dirty''
		programs could write to the screen memeory as they like
		(although the programs may break on the higher frequency..).

		Comes with software for the AUTO folder, plus a configuration
		program. 

That's about it, very small test for c't (only two pages, no screen shot).

In the May issue of c't, a card using the INTEL 8xxxxx graphics controller
and 1MB memory, is tested, HOT STUFF !!. Claimed to sell with monochrome
19" monitor for the 1660 x 1200 mode for 5500 DM. The board even
has a socket for the MC68881, so that you don't have to loose your
coprocessor.
