i bought both good ones.. i bought a viewsonic e70f and an LG F700B... both anit-glare, eyestrain free, perfect flat monitors...
according to me the Viewsonic rocked... i say it is the best of the 17" monitor lot... anyway,,

there are card that come with a DVI and D-SUB.. D-SUB beign the normat VGA connector... you connect your 1 st monitor to the D-SUB connector just as you would with a normal monitor... then use a DVI-DSUB adapter and plugin your second monitor.... and these types of cards are called dual-heads...

no... you can use any normal monitor for a dual-head graphics card..you only need the adapter(which came with my gfx card)..

hope it helps,
