Is this adapter bidirectional?

No. This adapter only works from DisplayPort (computer/GPU) to HDMI (monitor/TV). It does not convert HDMI sources (like PS5/Xbox) to DisplayPort displays.

Does this adapter support VRR, G-Sync, or FreeSync?

No. It does not support VRR, G-Sync, or FreeSync. It supports fixed refresh rates up to 8K@60Hz, 4K@120Hz, or 4K@240Hz on compatible GPUs and displays.

What should I do if I don’t get the expected resolution or refresh rate?

Make sure your GPU supports DP 1.4 with DSC, your display supports the resolution/refresh rate, and your drivers are updated. Use a certified HDMI 2.1 cable. For help, search “Cable Matters 102101/102103 Troubleshooting Instructions.”

Does this adapter work with gaming consoles like PS5 or Xbox?

No. It is designed for DisplayPort-equipped GPUs only and is not compatible with PS5, Xbox, or other HDMI source devices.

Why do I see flickering or color distortion?

This is often caused by signal loss from long or poor-quality HDMI cables. Use a shorter or certified HDMI 2.1 cable, or lower the resolution/refresh rate.

utilizzato su tv lg oled evo 48" per trasformare il segnale da DP1.4 a hdmi2.1. Con questi adattatori riesco a far funzionare correttamente le 3 TV (1 hdmi2.1 diretto, 2 con questi adattatori) senza alcuna perdita di segnale (cerca "lg oled no signal error"). Riesco a far funzionare correttamente nvidia surround (dovete disabilitarlo prima di riavviare il pc, altrimenti avrete dei problemi di visualizzazione all'accensione). Unica pecca, a volte i monitor collegati con questo adattatore non rilevano il formato colore output (da nvidia panel control): RGB. Per farlo rivedere e poterlo configurare dovete sconnettere e riconnetere il cavo dalla GPU.
