如同ATI Eyefinity與NVIDIA 3D Vision Surround,Intel也試圖強化內顯多螢幕支援能力。從Ivy Bridge開始新增1組數位輸出管線,當時採用分享DPLL設計,得使用2個數位搭VGA類比輸出,才能構成非對稱3螢幕環境。Haswell則是做了番強化,實體數位介面(digital display interface)增設為3組,正式支援對稱3螢幕顯示。
此外,Intel將數位介面從PCH晶片組移置到處理器內部,能夠直接處理數位輸出訊號。其中Digital Port D輸出組,支援 VESA eDP v1.2規範(Embedded DisplayPort),是特別為AIOs電腦平台應用設計。至於傳統LVDS與SDVO支援則是移除,只保留下2條FDI通道連接到PCH,用以支援VGA類比輸出。
據官方資料顯示,其DisplayPort 1.2版本介面支援HBR2(High Bit Rate 2)和MST(Multistream Technology)。MST賦予DisplayPort介面,支援2部顯示器同步顯示2560 x 1600解析度(WQXGA)訊號,或者是4台同步顯示1920 x 1200解析度畫面(WUXGA或1080p)。DisplayPort最新的HBR2標準,資料傳輸速率可達5.4Gb/s,得以支援4096 x 2304解析度,或者2560 x 1600解析度的3D影片訊號。
