Intel Arc 750 faces problems with dual displays via DisplayPort connections.
Intel Arc 750 faces problems with dual displays via DisplayPort connections.
Recent PC build completed over the weekend with all components replaced. Motherboard: Asus ProArt B760 - Creator D4 CPU: Intel i9 12900K RAM: G Skill Ripjax DDR4-3200 Power: Corsair RM850x 850 Watt, 80+ Gold GPU: Intel Arc 750 Limited Edition Drive: Samsung 980 Pro, 1TB, M.2 NVMe Displays: Asus ProArt PA278QV, x2 The setup was powered on smoothly and the display outputs via MOBO (1 HDMI + 1 DisplayPort) functioned properly. I updated BIOS to the latest version, installed Windows 11 Pro - 64bit with a full update, and updated all drivers. Initially, only one display worked with a DisplayPort cable; after reseating, the issue persisted. I tried different cables—some worked, others not. Testing one monitor at a time confirmed that each cable connected to its respective display was functional. Plugging in a second monitor via a DisplayPort port resolved the "no signal" error. Using an HDMI port on the card fixed the problem. Still puzzled about why the card couldn't send signals to two DisplayPorts simultaneously. Any insights?
Have you seen if it gets fixed? I’ve been digging deeper into Intel Arc’s potential and found this discussion.
You're experiencing the same issue with your A380. It seems the displays behave differently depending on whether you power them on or off. Using two DP ports and an HDMI port works normally at startup, but manually turning off a display causes it to lose signal when you turn it back on. Removing the display from system settings resolves the problem, though it returns when you turn it on again. The issue only appears after rebooting until the next time you disable a display.
