Just got a Samsung SyncMaster S22B150N monitor off Dabs.com and to my surprise its only got a vga socket which i find strange as its a full HD monitor. My question is the graphics out of my pc is a DVI-D
You'll get a much better picture with a full DVI connection, and there will be no need to fart about with pressing the Auto-Setup button.
You can send the Samsung monitor back to Dabs within 7 days of receipt under the "Distance Selling Regulations" for a full refund (you bear the cost of return postage, and it must be in its original packaging and in a resellable condition). Then buy a replacement with a DVI, or preferably, both DVI and HDMI inputs for some future-proofing.
This is a very good monitor - I've been buying a lot of these for work.http://www.amazon.co.uk/BenQ-GL2450HM-Widescreen-Multimedia-Monitor/dp/B005OPLG0O/
