How to fix sync signal loss on the Biostar A320MH PRO?
That horizontal tear right across the center of the screen was incredibly distracting during sprint sequences, making the beautiful vistas look broken. I found that the PCIe bus on the Biostar A320MH PRO was hitting a 4-6ms clock deviation relative to my monitor's refresh rate. My first instinct was to enable V-Sync in-game, but that spiked my input lag to a disgusting 70ms—it felt like I was dragging my character through mud. I scrapped that and went into the GPU control panel, disabled in-game sync, enabled Fast Sync, and capped the global frame rate at 57 FPS. Suddenly, the tearing vanished and input lag dropped to a crisp 20-26ms. Interestingly, locking it at 60 FPS still left some micro-stutter, but dropping it by those 3 frames hit the sweet spot. Chipset temps are idling between 45-52℃, and using a sync analysis tool confirmed the waveforms are perfectly aligned now. Memory temps are holding steady at 58-63℃.
