    Fatal1ty b450 gaming-itx/ac HDMI problem

    Good to hear a different cable fixed it for you. What resolution/framerate/pixel format were you running? A DP->HDMI adapter fixed the dropout issue for me, but it must not pass all the EDID metadata or whatever information the TV needs to identify that a PC is connected so it can use the...

    Yeah, you're probably right about the refresh rate. It was just an idea since maybe it'd behave a little differently than an adapter...or maybe not. Cables do definitely matter with HDMI. I remember the first time I hooked up an UHD Blu Ray player to my 4K TV and was getting white speckles...

    That stinks. Radeon Software shows 4:2:2 and 4:2:0 options for me, but it could be those formats are only supported on TVs and not your monitor. The 4:4:4 options give me dropouts like you're experiencing. The only other thing I can think of is maybe trying a dedicated DP -> HDMI cable (like...

    Fatal1ty b450 gaming-itx/ac HDMI problem

    Interesting. I guess I forgot to mention in my posts that I've been running 2160p60. I forget if lowering it to 1080p or lowering the framerate fixed the dropouts for me since one of the main reasons I built the HTPC was to have 4K 60fps playback. I definitely tried a number of different cables...

    Sounds good. And yeah, I think your current DP -> HDMI workaround is the best if you're using it as a normal desktop PC and need the full range RGB. Using a DP -> HDMI adapter also solved the problem for me, however then my TV wouldn't auto change to the "Graphics" preset, which I found more...

    Fatal1ty b450 gaming-itx/ac HDMI problem

    I ran into the same issue with the same motherboard and a 3200G last year when I built it as a HTPC. The only solution I've found while using HDMI is to lower the output pixel format to YCbCr 4:2:0 with 8-bit color. This loses color data, but hasn't been a huge deal for me using it on a large TV...
