I'm experiencing input lag on both monitors while using HDMI scaling (10% for proper size on my second monitor). The only time it happens is when I'm watching Youtube at higher than 480p resolution. I can watch 1080p while not using HDMI scaling but even 1% underscan creates lag. I recently upgraded my GPU and my previous system didn't experience this issue. Any thoughts?
OS: Windows 10 64-bit
Driver: Adrenalin 19.2.3
Dispaly (Primary): Samsung SMBX2250
Display (Secondary): Daytek QHTF42
Motherboard/BIOS: Gigabyte X470 Aorus Ultra Gaming/American Megatrends F6, 2019-01-25
CPU: Ryzen 5 2600
Power: Corsair VX550w
RAM: G.Skill 16GB DDR4 (2x8)
I've uninstalled the 19.2.3 driver and I have reverted to Crimson ReLive 17.7 and Youtube runs beautifully at 1080p with 10% HDMI scaling. I would keep it at 17.7 but EA's Anthem (the game I bought the new RX 580 to play) requires a more recent driver to play.
