I recently bought a Lenovo IdeaCentre 5G 14IMB05, which offers both DisplayPort and HDMI, but neither VGA nor DVI, which are the only options on my 60Hz SyncMaster B2230. Technically a solution to that would be either a DisplayPort-to-DVI or an HDMI-to-DVI adapter. But do these indeed offer good results? If both offer a decent solution, is there any quality difference between them?
