Custom Resolution Utility (CRU)

[comemierda]

So I have this display (Monitor Hardware ID: LGD046F) on my laptop. It only reaches 63hz overclock , and I have seen many users with this display reach this cap. That makes me wonder if there is some sort of software cap.

Here are my LCD BIOS settings: http://imgur.com/tV8jOgh

Anything I could try?

63 Hz with what timing parameters? What happens after 63 Hz?

I recently purchased the Dell monitor with hopes of running 4k at 60hz. I know this is likely pushing it for the capabilities of my video card, but I have heard that some people can at least get it to run at 45Hz with CRU and the pixel clock patcher ( http://www.hardwareheaven.com/community/...ys.226759/ ). I've already run the pixel clock patcher (thank you again for that utility) and it worked effortlessly. Where I'm struggling is to get custom resolutions to appear as an option in Windows 10. I have read through many pages of this post (though, admittedly, not all 259 of them) and I think my problem is largely just due to not understanding what I'm doing with CRU. Below is a screen shot from CRU. After I click 'OK' and run the restart utility (I've used both 'restart.exe' and 'restart64.exe') my display driver successfully restarts but I do not seem to be able to get anything other than a 3840x2160 @ 30Hz to be able to appear.

I've tried to add 3840x2160 @ 60Hz to the standard resolutions box and I get the red text telling me that it's not supported.

I feel rather sure this is an operator error, but hopefully you'll be able to point out what I'm doing wrong.

The problem is you're trying to get 3840x2160 @ 60 Hz on an old video card that has no way of supporting such a resolution. 3840x2160 @ 60 Hz requires HDMI 2.0 or DisplayPort 1.2 with HBR2, neither of which are supported by the HD 6870. DisplayPort without HBR2 on AMD cards is usually limited to 360 MHz pixel clock with 8-bit color and 480 MHz pixel clock with 6-bit color. Some early 3840x2160 monitors used multi-stream transport to get around that limitation, but I don't think the P2715Q has that option. The patch does nothing for DisplayPort limits, so you'll have to keep those limits in mind when adding custom resolutions. Have you tried other refresh rates like 40 Hz and 50 Hz?

63 Hz with what timing parameters? What happens after 63 Hz?

LCD Standard timings. Above 63hz=Black screen (with backlight).

Also even as 960x540 (half full HD) wont pass from 63hz.

Can someone explain me the Latency Information.

I have Philips 7007 3D TV .

Does changing the Include latency data changes anything or effect anything , for both or 2D or 3D ? what does it do ? can I improve the latency or lag input of the TV or any TV using this ?

for me the
Video Latency - 180ms
Audio Latency - 180ms

Also what does the Supported contents types do ? I have it default checked - Graphics - Photo - Cinema - Game

Thanks

That sounds like a hardware limitation, especially if everyone with the same panel is seeing the same limit. If the refresh rate is listed in the Windows display settings, then it's not a software limitation.

That's just the latency information provided by the TV. Changing the values wouldn't affect the latency. That information was meant to be used to help synchronize the audio with the video, but that information isn't used on a PC. If your TV has a PC or game mode, then you should use that to reduce the lag.

It defines what content types the TV supports. Some TVs can automatically change picture settings and image processing depending on the content type. I know the NVIDIA control panel has an option to set the content type reported to the display for the desktop. I don't know about AMD.

Pixel Patcher patched, CRU with the latest 1.3 version.

I cannot push 4K@60hz over my DP to HDMI 2.0 adapter (Club3D, with the latest firmware by the way).

Only way I can get 60hz is if I step down to 1080P. Most of the time, browsing, this isn't an issue. But for anything else, the 30hz becomes painful very fast.

Before I go buy another graphics card, as I am looking at the GTX 1070 right now, I want to make sure that there isn't anything 'wrong' with my current setup.

The TV can do 4K@60hz as verified by members over at HardOCP: https://hardforum.com/threads/seiki-42-4...e.1886908/

Why I cannot do it is beyond me... Custom resolutions are pushed into CRU, TV is set on HDMI 2.0, and Pixel Patcher is done.

Dealt with this for about a year now but now it is REALLY getting to me especially when I know this TV is 60hz capable.

Does ANYONE know what to do to proceed from here aside from the obvious which is to get a Graphics Card that has multiple HDMI 2.0 outputs. I think my Graphics Card is the limiting factor here and not the TV itself.

If the TV supports 3840x2160 @ 60 Hz with HDMI 2.0, then you shouldn't need to use CRU or the pixel clock patcher. It should just work out of the box with the Club3D adapter. CRU 1.3 can read extension blocks, so you shouldn't need to add anything manually. CRU should already list 3840x2160 @ 60 Hz as one of the resolutions, possibly in the extension block. There should also be an HDMI 2.0 data block in the extension block.

Should but doesn't. I think it is the graphics card to be honest. the HDMI port is 1.4 and I think those guys at PowerColor cheaped out and used a DP 1.0 instead of 1.2 which explains why I cannot push above 30fps.

Seems like we are at a stale mate here. What do you recommend?

Once the new GTX 2080s come out, which I hear is around March/April/May, the GTX 1070 will be worthless (~$200s) and I will snag one there at a discount to remedy this permanently. I'm never buying cheap Graphics Cards again! Extra couple of $$$ in addition to the $200 I shelled out would have precluded this all together.
