The CMV is made by Chi Mei Optoelectronics, the fourth largest LCD manufacturer in the world (Samsung is the largest). They're the original manufacturer of lots and lots of LCD monitor brands; CMV and Polyview however are their own brands. All CMV (and Polyview) monitors that are DVI-capable come with a DVI cable (as well as VGA cable). There are no monitor drivers, it's standard Plug and Play. Generally speaking, if you go for it, you're going for the panel quality as opposed to the exterior design, since Chi Mei monitors have a sturdy plastic finish (as opposed to a metallic one) and the panel tends to be thicker than other manufacturers' panels. This is because they use a direct backlight system (the backlight is directly behind the LCD panel) while most manufacturers use a side backlight system (the backlight is actually in the bezel on the sides, then diffused inwards onto the screen). Unfortunately they never capitalized on the really thin bezel design philosophy that could've been achieved with their backlight layout. However, this means their monitors are brighter than most, and lighter due to their plastic instead of metallic casing; a Polyview 19" is as heavy as a Samsung 17". (As a sidenote, all LCD TVs use a direct backlight system because that's the only way to generate enough light for a TV, and when you're looking for 10-20 feet away, users don't mind if the panel is somewhat thicker). Thus CMV/Polyview is geared toward more the utilitarian or practical user as opposed to the type who buy one as a desk ornament, i.e. for looks. I'm serious. I've had a friend buy a $600 17" Samsung over a $300 19" Polyview because "whoa, that metallic finish looks so good!" even though the Polyview's an MVA panel and the Samsung's a TN and I said I'd make sure there were no dead pixels for him for the Polyview. Hope he got his ladies considering he could've done a dual 19" setup instead with that money. Oh well.
Anyway, CMV and Polyview are worldwide brand names, but in the U.S., the distributor is Amptron, which is who you'll be dealing with for returns/RMA if you ever need to, if you're in the United States. I used to work for them, which is both a disclaimer as well as why I know about the brand. Amptron's dead pixel policy is 3 bright sub-pixels, 3 dark sub-pixels, or 5 total sub-pixels, max. However, don't expect them to exchange your monitor if it only has one or two defective sub-pixels. Samsung's dead pixel policy (in the U.S.) is 9 total sub-pixels, max (no bright or dark categories), regardless of what you might've heard about them running a zero defect policy (which is applicable only in South Korea, where they're based). I have no idea if Samsung will exchange for one or two defective sub-pixels.
I haven't heard of the CMV CT-726D before; it's a new product. Don't confuse it with its older and slower analog-only cousin, the CT-726A. Note that the monitors look the same, as they're using the same exterior casing for the new panel/electronics. The speakers are the usual monitor quality speakers, which means they're more for office use and not exactly Bose. On the other hand, the Samsung doesn't come with speakers. Other than that, both panels are TN so I'm not sure what else there is to say.
