That has nothing to do with CRU. CRU does not implement FreeSync.

I fixed issue in games by disabling response time of monitor. In firefox videos still goes to blank if hardware acceleration is enabled, if i disable it it works as usual. Which HDMI 2.0 features to enable?

RE: Custom Resolution Utility (CRU)
@ToastyX

Graphics Card:- AMD rx 570,
Monitor :- Benq gw2470h va panel 60hz,
OS:- Windows 10, 1903,
Cable:- HDMI 2.0


Overclocked to 75hz with AMD driver. Than downloaded CRU.
Tried 100s of freesync ranges with different settings but same problem exist.

All Games including freesync demo app gives black screen splashes. Works for few seconds than black screen.. and repeat.

Disabling freesync in amd driver solves the issue but i want freesync man.

Any help would be appreciated.

I don't see anything that says GW2470H is a FreeSync monitor.

I thought this software turns non-freesync monitor to freesync monitor.
Many youtube videos and tutorials are present there using this tool.
But they didn't work for me((

When this monitor can display between 40 to 85 hz(overclocked it).. isn't it possible to make it a free-sync one?

No, FreeSync is not the same as changing the refresh rate. FreeSync runs at a fixed rate and extends the vertical blanking to delay the next frame. CRU is usually used to add custom resolutions and to edit the FreeSync range, not to add FreeSync to a non-FreeSync monitor. Adding FreeSync only works under very specific conditions. Either the monitor must have a scaler that supports variable vertical blanking, or the monitor must not have a scaler, and the driver will only allow FreeSync if it thinks the monitor supports HDMI. I don't know why people think it can be done with any monitor. Almost all non-FreeSync monitors with HDMI have scalers that don't support variable vertical blanking. I've only confirmed one monitor that can do this with DVI because it doesn't have a scaler, but it's a pain to enable because the driver blocks the ability to enable FreeSync with DVI even though the monitor is capable.

RE: Custom Resolution Utility (CRU)
I recently bought an LG C9 OLED TV, after previously owning a B7 and a C8. Its main selling point is 1440p@120Hz refresh rate. I'm having some issues and was hoping that @ToastyX or anyone else would be able to help me out.

With the B7 and C8 (which only support 1080p@120Hz), I connected my PC to the receiver (a Denon AVR-X4400H) using my GPU's (1080 Ti) single HDMI out. If I do that with the C9, only 1080p is available at 120Hz, for some reason (4K@60Hz works flawlessly).

eARC is currently not working with my TV and AVR (known issue between 2017 Denon receivers and the C9), and regular ARC causes massive audio delay (also a known issue on LG OLEDs). So, the only alternative to have 1440p@120Hz video on the TV and audio coming out of the speakers connected to my AVR, was to connect the GPU directly to the TV (through HDMI), and use one of its three DisplayPort outs to connect a second HDMI cable to the AVR (using a DP to HDMI adapter).

Now, the problem. Windows sees those connections as two individual displays. I can either extend or clone the picture from the primary display (TV) to the secondary one (AVR). If I extend, I get 1440p@120Hz, but no high definition audio formats support. If I clone, I get support to all audio formats, but only 1080p@120Hz.

Is there any way to use CRU to fix that? Here are some screenshots showing what the available settings look like:

Extend:

Set up screen
Available resolutions - PC and TV
Supported audio formats

Clone:
