Hey ocFTW, the BIOS version 2.10 seems to have fixed issues for me.

It just took ASRock 6 months to make the product work as advised...

Help me out here guys, where do you see in the specs support for HDMI 2.0?

Or is that inferred from the 4K x 2K (4096x2160) @ 60Hz spec for the HDMI2 output?

You are all aware that the HDMI1 output is rated for 4K x 2K (4096x2160) @ 24Hz / (3840x2160) @ 30Hz, not the same as the HDMI2 output?


you typed all that up and posted different links but couldn't check that HDMI 1.4 is capped at 30Hz for 4K and only HDMI 2.0 can do 4K@60Hz?



yes, it's inferred from the 4k@60Hz support claimed on all marketing materials for this board, the manual and the spec listing on asrock's website

Also, as it is clearly stated  in the manual, I think all of us that are  complaining are aware that there is a difference in which port should be 2.0 enabled and that you have to use the correct one for 4K@60Hz

Asrock has just been too non-responsive on this issue that has been around for months.

For those with flickering on the TV image, have you tried disabling any of the C State CPU power saving options? Such as, not using Package C State support, and disabling C6 or C3?

You are aware that dual channel memory is required for support of 4K x 2K @60Hz?

Have you tried the Intel Graphics driver version 15.40.14.4352, that claims to fix flickering with Skylake processor graphics? Available here:

https://downloadcenter.intel.com/download/25620/Intel-Graphics-Driver-for-Windows-7-8-1-10-15-40-6th-Gen-?v=t

There are also several Beta graphics drivers available from Intel. They may not directly address the flickering issue, I'm just giving you others to try. This is the latest one, there are links to two others on this page:

https://downloadcenter.intel.com/download/25848/Intel-Beta-Graphics-Driver-for-Windows-7-8-1-10-15-40-

I also found this driver, which seems to be the same version as the 4380 Beta driver, but is not labeled as a Beta. Confused  Here it is:

Should i update even though the tool tells me i have 1.36?



I don't think so, my board came with 1.24 I think and the utility updated me to 1.36 which is the latest on asrock's page for our board

if you board already came with 1.36 just means it's newer stock than when I bought my board

It looks like the MegaChips firmware is still very buggy. Unhappy

yes

seems that way

they should stop marketing this board as having HDMI 2.0  or make a bigger announcement so it puts pressure on MegaChips saying their MCDP2800BB is faulty and they have to issue partial refunds to customers

Again, I have no problem playing videos; it's clearly signal dropout and it happens anytime.

With the new firmware I can use my computer for an hour without flicker and then it suddenly starts.

Guys and gals, I'm outta my league here. I use an Asus HDP-R3 and my 34TB of movies are in ISO which is native to the HDP. Still, I'm only trying here to help. Take mercy on me.

On the FAQ page of MPC-HC is a couple of pointers for tearing and glitches.
Quote

Why am I seeing tearing in the video?

The video display is experiencing a synchronisation issue, try enabling V-Sync by pressing V. If you have more than one monitor connected make sure you extend the screen instead of duplicating it.

Why am I seeing strange glitches in the video?

Hardware acceleration is most likely not working correctly. Try going to Options ??Internal Filters, right-click the list on the right and click ?œDisable DXVA filters??and then reload the video (Ctrl+E or manually). If this does not solve your issue, and your video plays correctly in other video players then please make a bug report.

Yes it does happen on the desktop, while browsing, and so on. There's no pattern.

MPC-HC embeds LAV, which supports DXVA2 and QuickSync decoding out of the box, you don't need any codec packs for that.
