Can't seem to get any resolution over 2880x1620 to work

Whatever I try i can't seem to get any resolution over 2880x1620 to work without color compression or reducing refresh rate.
I'm using CRU 1.3 with 2 GTX 1080 GPU's in SLI and a Sony KD55x8509C UHD TV wich both support 4K resolution @ 60hz 4:4:4 chroma.
Reducing refresh rate to 30hz or forcing 4:2:0 chroma subsampling works
So... you would think that the HDMI cable is to long or has poor build quality to transfer the signal correctly.
Well..the weired thing is that 40k 60hz 4:4:4 works perfectly without using the CRU utility. (tested using various chroma subsampling testpaterns) So why does CRU fails to achieve these resolutions?

I would like to set up all resolutions like 1440p, 1620p 1800p and 2160p. Without using CRU i only get standard 1080p, 1440p and 2160p. With the usage of CRU I can get 1080p, 1440p and 1620p but no 1800p and 2160p without color compression. The Standard EDID UHD resolution simply dissapears by using CRU.
I tested the hell out of the CRU application. Putting these resolutions in all possible locations and extention blocks without any result.

Does sombody has any idea what is going on here?

(TV is updated to latest firmware and is set up for enhanced HDMI singnals)

Any help would be greatly appreciated! Smile

Hi there, I am trying to overclock my 1440p hannspree monitor to 80+hz, but am having some issues doing so.

I have tried installing different versions of AMD Crimson Drivers, but they all run into the same issue when I patch them using Toastys Pixel Patcher it doesnt seem to work and I am using a R9 Fury btw.

If there is a way of doing so manually PLEASE let me know as the 297mhz HDMI limit is whats limiting me.

hello, i'm trying to get freesync to work but it doesn't seem to do work at all.. i can get my monitor detected as hdmi and have to do the replug the monitor thingy or it starts up with a black screen.

am i doing something wrong? my monitor does not have a scaler and as far as i know it should be able to do it like a qnix, yamazaki catleap... before trying freesync it was overclocked to 96hz and that always worked so far. am i doing something wrong or is my monitor just not compatible? its a dual link dvi 1440 panel with no scaler. more info here : http://www.overclock.net/t/1555354/offic...40p-ah-ips

Can't go above 75hz? And other questions

January 16, 2017, 2:56 pm

Hello. CRU is amazing, but I have several concerns and questions about it. First of all, here are my relevant specs:
ASUS VS228H-P
AMD R9 280X

1- I can't seem to be able to go above 75hz, with a pixelclock of 174.57mhz. I've applied the pixelclock patcher successfully, and the HDMI block, but they don't seem to have done much. Is my monitor just really unable to go beyond that?

2- Since overclocking my monitor, I've seen a few black lines appearing across the screen, which worry me. It has only happened 2-3 times in the past 2 days, which isn't bothersome in itself, but I fear I may be damaging my monitor.

3- I'm using MSI afterburner to monitor framerate and frametime while gaming. My framerate is definitely going to 75fps, but my frametime remains exactly the same as when I'm at 60fps. Why is that? I've compared between 60 and 75 on my monitor, and 75 is visibly smoother.

4- Should I bother adding any of the audio blocks?

So Hannspree just got back to me saying that my 1440p monitor supports HDMI 2.0, but the problem is my R9 Fury only supports HDMI 1.4. If I was to purchase a active HDMI 2.0 to Displayport 1.2 adapter, would that let me overclock my monitor up to a 600mhz pixel clock limit eg 100hz+, because it will be conected to the displayport on my Fury? Thanks

[Troubleshooting] FreeSync + Eyefinity over HDMI?

January 18, 2017, 5:08 am

Hi everyone!

I apologize if maybe this is not the place to ask, but I'd really appreciate your help with the following situation: I've been planning buying a triple monitor setup, since I'm on a budget I chose the LG 24MP68VQ-P for the monitors, and would buy a RX 480 MSI Gaming X 8GB for the time being to later buy a second one.

Considering the following:
  • Monitor's Input: HDMI 1.4
  • Card's Output: 2xDP 1.2a, 2xHDMI 2.0b, 1xDVI-D

I would like to set up the monitors via Eyefinity which, to my understanding, will require an active DP - HDMI adapter -- so I can connect 2 monitors directly to the card's HDMI and use the adapter to connect the remaining one. I can't use a passive DP - HDMI adapter since the RX 480 requires at least one active connection.

My issue comes when doing some research about the FreeSync compatibility. The monitors are HDMI FreeSync compatible, that is each one of them can use FreeSync via HDMI independently. But it seems that the active DP - HDMI adapter would cause troubles and won't allow the use of FreeSync with the monitor connected to it while in Eyefinity setup.

There are some related questions on the AMD forums, dated back in August '16 and answered by the same AMD rep (TL;DR: the adapter needs to be FreeSync compatible?).

Here's where I may need to apologize for my narrow knowledge on how monitors, active adapters and cables work, but what the rep suggest doesn't seem logic to me. Given that FreeSync is basically a communication protocol to enable the sync of frames between the GPU and the display, I'm not sure I understand why would an active adapter prevent this (assuming of course that the adapter complies both with DP 1.2a and HDMI 1.4 specs, and allows for the required bandwidth and refresh frequency). For instance, using this or this active adapters. Might it be related to how the DAC works with the signal? I haven't been able to find anything related to active adapters + FreeSync.

Worst case scenario I would be able to use Eyefinity @ 75hz without FreeSync (which to me is good enough given the budget and that I'm expecting the Crossfire 480s to be able to handle the resolution nice enough).

What do you guys think?

Thanks for your answers (specially of you read the whole wall of text)!

TL;DR: Would I be able to use Eyefinity + FreeSync on a triple LG 24MP68VQ-P + RX 480 MSI Gaming X setup?

Omen 32 monitor, "out of range" message - any way to around it?

Hi.

I have a new HP Omen 32, which is pretty awesome. I saw on Hardforum that someone with an earlier firmware version of this monitor than mine was able to overclock the monitor just fine. But, any overclock of mine above the advertised max of 75hz, gives me this "out of range message":

[Image: kAD2DEG.jpg]


It looks to me like this is an artificial limit, imposed by the firmware. And it wouldn't be a problem, except for the message, and the monitor going into sleep-mode after 30 seconds.

Is there a way to bypass the monitor's prevention of overclocking?

Would this guide for hacking a monitor's FreeSync range be of any use in changing its recognized in-range hz spectrum?:
http://www.guru3d.com/news-story/owners-...-hack.html


Also, would there be a way to extract an earlier firmware version from one monitor, one without the overclock prevention, and apply it to another monitor?

4K Output on NVIDIA 9600M GT - Success

January 24, 2017, 9:18 am

Thank you Toasty for a great tool. After countless hours/days of trying to get 4K output to work on my old Macbook Pro with Windows 10, I was able to finally get a handle on what was going on using CRU, and then just hours later figure out what to do. I will describe the problem and process I went through to help out anybody who is in the same situation with similar hardware or not.

I have a 2009 Macbook Pro with an NVIDIA GeForce 9600M GT with mini DisplayPort. I installed an SSD and Windows using BootCamp and use it as my regular work computer. I just bought a UHD TV and tried to hook it up as a monitor. I do database design work and it helps to have a huge screen.

Using an AmazonBasics mini DisplayPort to HDMI and an AmazonBasics high-speed HDMI cable, I plugged it into the Samsung OneConnect box for PC/DVI. That worked fine for 1920 x 1080 output. In the NVIDIA Control Panel, I created a custom resolution for the Samsung of 3840 x 2160 @ 30Hz which I then selected in Change Resolution and voila! it worked. Or so it seemed. As soon as my main laptop screen turned off (screen saver, sleep mode, etc), I could not get it to turn on again until I unplugged the cable to the (also dark) TV. This is the problem I tried to resolve for days. The only way to get the TV to show anything and not turn the laptop screen black was to uninstall and reinstall the NVIDIA driver.

Through googling, I read a lot about EDID and tried other utilities and then made my own override with an INF file, with Native resolution of 3840 x 2160 @ 30Hz. Didn't work.

Once I had found CRU, I started to get a better understanding how the monitor profiles were managed. I deleted my override by resetting all profiles. I noticed that a profile was being created automatically for the TV with two Detailed Resolutions: 3840 x 2160 @ 30Hz and 1920 x 1080 @ 60Hz. I deleted all of the sub-HD resolutions and saved it. The 4K resolution would not show up in Windows Settings and all of the sub-HD settings would still appear. After trying this several times with small variations in the settings (60 vs 30Hz, interlaced vs non-interlaced, etc) without success, it occurred to me that Windows may not be showing the 4k resolution because the NVIDIA driver is not telling it that it can handle it. So I created a custom resolution in the NVIDIA Control Panel and took a screen shot of all of the settings. I opened CRU and modified the 4k settings of the monitor profile to match. I restarted, connected the TV, went to the Windows Settings. The resolution for the Samsung now included 3840 x 2160 (Recommended) in addition to the 1920 x 1080. None of the lower resolutions appeared any longer. Sweet success.

I don't know if I could delete the custom resolution from the NVIDIA Control Panel now and it would still work. In any case, getting the exact output settings and using CRU to modify the profile was the key to making this work.

120hz no more, I'm stumped.

Ok Ill try and be concise with dot/bullet points, Also I think I've narrowed it down to the mini display port so If i'm not meant to post this here (guessing that would constitute a hardware issue) I'm sorry.


* I bought a 2nd hand 120hz monitor to play Overwatch as my new laptop can only display 60hz (Alienware AW2310)
* I plugged it in and both windows and nVidia CP saw it as 120hz but when I clicked apply on either it crapped out..
* I managed to create a custom res w/NCP @95 hz and figured its a huge improvement and the monitor was cheap so it will do for now.
* Then I loaded Overwatch and to my amazement it ran at 130hz!! (Both FRAPS and in game counter had the same 130FPS) So I figured that was fine, Windows was 95hz but the game ran so that's all I cared about.
* A few days later I updated nVidia Control Panel and that's where tings go down hill, Now I'm rocking a sweet 60hz again... Shits out as soon as its over 62hz!! It no longer has the drop down box option for anything over 60hz.


After reinstalling windows and rolling back (and forward) drivers I'm still in the same spot. By this time I'm thinking it has to be the mini DP not being able to send that much data. Have a look at the attached pic and tell me if it should say Dual Link or DVI-D as I didn't pay any attention once I got it working before.

Laptop is a Clevo i7 6700HQ/16GB/1070GTX

Also when I first plugged it in windows knew it was a 3D monitor and now it doesn't say that in display settings at all.

Any advice would be greatly appreciated and if you think the monitor has just crapped it that's cool, I just want to resolve this as it was a recent eBay purchase and if I cant get it to work I want to take it back.

So Ive been having issues with my Hannspree HQ271 skipping frames at 60hz.

I just swapped my monitor for a replacement with the manufacturers and put my new monitor to the tests. Its having the exact same issues where on all connections it will skip frames at 60hz. Surprising enough its stable on the same refresh rate as the old one which is 57hz. I am now super confused and not sure if theres something on my computer (software or hardware) which is doing this or its just the monitors firmware which is causing these limitations.

I hope someone can help as I don't even know what to do now as I have tried everything from what I know.

Thanks

LG 29um68-p - Frameskipping - out of range, and other questions.

Hello..
Thanks for a nice utility. I just write what I know so far, and if somebody can come up with something, please do. Thank you!

system:
Lg 29um68-p paired with 970 GTX

Okay! So I just got this Lg 29um68-p monitor, and the first thing I did was to bump up the Hz to 80Hz, with HDMI, without changing anything, except for making a custom setting in Nvidia control panel.

A bit higher and it seemed unstable.

I noticed frame skipping, so I changed the cable to a DP cable.

Used CRU this time.

Still frame skipping anywhere from 70 Hz to 85Hz. Maybe lower but haven't tested, as it already tells me that it isn't the monitor alone that's causing the frame skipping.

I also used the reduced timings.

So! Is there anything else I can do to reduce the frame skipping?
I'm not sure I noticed the skipping in games?
Can it be different in games, that on the desktop?

Out of range issue:
I could bump the monitor up to 90Hz, it "works" but says "out of range" from 81Hz and up. Have not tried going higher.
I read in another thread here, that it is a limitation in the Firmware. That makes sense. To me it seems this monitor can do much more than its limited to, so I hope for some hack to show up.

Anyway, I just wait for the VEGA to launch, so I at least can get 75Hz, and possibly 80Hz refresh rate.

Have a nice day!

how can I create a custom resolution with 4k 2160p60hz 4:2:0?

Huh Hello i'm have a 55X9005A with hdmi2.0
and use a FURY X with DP Active adapter from club 3D CAC 1070
I limited to 4k 30hz FULL RGB, the tv supports 4k 60hz on the
4:2:0 YCbCr but theres two limitations for me
1 - DP on amd drivers won't let me change
2 - tried create a custom resolution with Reduced blanked but return as Black screen
When I tried to talk to CLUB 3D I done everything that they said, but don't work

I begin to thinks that tvs don't support this 4:2:0 BUT
I install my PS4 and shows and choosed the 4:2:0 4k 60hz
but not working on the PC

I want the 3840x2160p 60hz YCbCr not as the main resolution, only to can choose that to play games

Hey there, fellas. I recently upgraded my pc quite a bit and got myself a GTX 1050 TI. Now the thing is, my monitor is pretty old, but I had no money to buy a new one and the optimal resolution is 1600x900 (it's an LG, I've long since forgot the model). Now the problem is the following: I can't select the 1600x900 resolution, it simply isn't there. I even tried with the CRU tool, but everything is messed up, it just won't work. I use an Adapter Displayport 1.2 male > vga female that should support up to 1920x1200. OS: Windows 10 Professional 64 bit

What's this effect on my projector?

Hello everyone, I've been a CRU user and forum reader for years now (yeah, silent majority, haha) and I think only this great community can help me solve this issue I'm having with my projector.

It's an LG PA1000 LED DLP and it's really versatile with CRU, I could overclock it to 1280x800@120hz by using the software, and it even accepts rare refresh rates like 119.88913621364 in case it's needed (no idea what for but it works! xD)

Thing is, in some horizontal movements I've been noticing some "color halo" around some picture edges, as the image it's not only showing motion blur, but also a kind of aquarelle painting effect. I can confirm it's the projector as I've tried several videocards to with it, a laptop, a VGA cable instead of HDMI. Nope, the same.

Here are the pics, I used this testufo link to test it (http://www.testufo.com/#test=photo&photo...0&height=0)

Still image
https://i.cubeupload.com/KG5ad2.jpg

Movement (1920pix/sec for exaggerating the effect, but it's visible even at 120pix/sec in the test, like, a little horizontal speed and the halo appears)
https://i.cubeupload.com/jIyB4C.jpg

In FIFA this color halo is visible in the grass if the camera moves too fast, and you can see that green and red color are like alternating
https://i.cubeupload.com/jEB1LE.jpg

My CRU settings:
[Image: http://i.cubeupload.com/IGbbMT.jpg]

I know that DLP got a rainbow effect by default, I'm sensitive to it and I could easily see it when the projector was set to 60hz, but it vanished when I set it to 120hz. But this is different, or maybe it's a combination between a slow color wheel and a high response time, I'm really really lost. Have any of you experienced something like this? perhaps I'm making a mistake in my CRU settings?

Thank you and greetings from Chile Big Grin

Laptop screen banding, blur, poor quality

Hi, sorry, not strictly a monitor but still... need some help. There's got to be something missing here. Problem is vertical banding, poor gradient quality, blurry text and fringing around letters. In short poor picture quality. Tried 2 replacement screens from same maker Innolux as well as Samsung. No change.
There may be some incompatibility between LCD and BIOS... some suggest dithering status=unknown. This has been since laptop was new.
AMD A6 6130 Radeon R4
What would be the best way to troubleshoot, test and define the problem?
If screen is not exchanging full info with BIOS or video card or for some reason they are unable to successfully communicate, then LCD will not do what it's supposed to do. The key is diagnosing the problem. Was considering using CRU to try different refresh rates but I don't have a full understanding what to expect and how to probe the LCD. Would love someone to chip in and give some guidance.
Thanks.

Hi, I've been trying to get UHD 60Hz 4:4:4 8bit to work for 2 months now. Please help me Smile

Here's my setup:
- ASRock J3455-ITX FW 1.2 with Intel HD 500 (Apollo Lake, HEVC)
- onboard LSPCON MegaChips MCDP2800 FW 1.61 (DP 1.2 to HDMI 2.0)
- Club3D 3m 4K HDMI cable
- Philips 43PUS6101/12 (HDMI3 set to YCrCb 4:2:2/4:4:4 mode)

I've tried Windows 10 (newest drivers) and Ubuntu Linux 16.10. The best I can do is UHD 60Hz 4:2:2. I've done days of research and think that all four components should be able to do 4:4:4.

I've asked Intel to add more controls to the HD graphics control panel but I wonder if they will ever implement it (RGB/YCrCb4:4:4/8bit).
https://communities.intel.com/thread/111279

The EDID of my Philips TV is total crap (the recommended resolution is 1920x1080, haha).
Is there a chance I can force 8bit mode and YCrCb 4:4:4 with CRU?

thanks
