Diagnosis
This intermittent signal loss, often called "blacking out," is typically caused by an HDMI handshake failure. In the Optoma UHD50X, this is frequently triggered by the projector attempting to adjust brightness levels via DynamicBlack or the PS5 pushing a bandwidth load that exceeds the capacity of the HDMI cable. It can also be caused by HDCP (High-bandwidth Digital Content Protection) synchronization errors between the console and the projector's internal processor.
How to Fix It
Follow these steps to stabilize the connection:
- Disable DynamicBlack: Navigate to the Projector Menu > Picture > DynamicBlack and turn it OFF. This prevents the projector from constantly shifting the backlight, which can trigger signal drops.
- Upgrade the Cable: Replace your current lead with a certified "Ultra High Speed" HDMI 2.1 cable. Even if you aren't using 4K/120Hz, these cables have superior shielding. Keep the cable length under 15 feet to avoid signal attenuation.
- Adjust PS5 Resolution: On your PS5, go to Settings > Screen and Video > Video Output. Change the Resolution from "Automatic" to "2160p" to stop the console from constantly polling the projector for supported resolutions.
If That Didn't Work
Try these advanced configuration changes:
- Force HDMI Version: Go to the projector's Settings > System > HDMI Settings and change the mode from "Auto" to "HDMI 2.0." This removes the negotiation phase and locks the signal.
- Disable VRR and HDR: In the PS5 Video Output settings, toggle "VRR" to Off. If the flickering persists, try disabling HDR to see if the bandwidth load is the primary culprit.
- Power Cycle Sequence: Turn off both devices. Unplug the power cables for 60 seconds. Plug in the projector first, power it on, and then boot the PS5.
Heads Up
Avoid using HDMI switchers or extenders between the PS5 and the UHD50X. These devices often introduce latency and HDCP errors that cause the exact signal drops you are experiencing.
