How to fix horizontal tearing on Onda 9D4-DVH in MH Wilds?
Watching a monster sprint across the screen is awesome, but those horizontal tear lines were totally killing the vibe. The Onda 9D4-DVH defaults to only 256MB of video memory, which caused a 15-22ms sync delay when handling 4K textures. I first tried enabling V-Sync in-game, but the input lag jumped to over 60ms—it felt like I was playing in mud, so that was a hard no. I went into the BIOS under Advanced Chipset settings and bumped the pre-allocated video memory to 1GB and enabled the Fast Response mode. Checking RTSS frame time analysis, the gaps dropped from 12-28ms to a steady 8-14ms, and the tearing completely vanished. I actually messed up the first memory bump and the system stopped recognizing my GPU entirely; I had to reset to defaults and try again. Board temps are 50-56℃ and RAM is at 42-47℃. Compared screenshots prove the fluidity is back. The controls feel snappy again.
