Hi I just bought a lovely new PC, delivered yesterday : 4GB DDR2 PC-6400 800 MHZ (4 x 1 GB 800) HIPER POWER 580W LOW NOISE/SLI READY MS WINDOWS VISTA HOME PREMIUM 64-BIT ASUS SKT-775 P5K S/L 1333FSB INTEL CORE 2 QUAD Q6600 1066FSB SKT775 Coolermaster Centurion 5 case Sapphire ATI HD3850 256MB PCI-E 2.0 I've got a 19" flat LCD monitor, with a RGB/VGA/d-Sub (?) connection (multi-pin plug with screws) on my old PC, and thought I could just plug this relatively new monitor into my new PC. But the new PC hasn't got any ports that I can see. It's custom-built and the company is now shut for Christmas, so I ain't got anybody to ask. I can nip down to PC World and get a new monitor today, if that's what I need, but can somebody tell me what I need to ask for? I've tried googling monitors but in the specs they don't really mention connections. And walking into PC World expecting some proper advice is really asking for trouble.... Thanks Chiffy
