Forcing 1920x1080 on 4k capable monitors in Surround impossible?

August 30, 2016, 3:31 am

I have a PC that simply refuses to run the monitors at their native (recommended) 1920x1080 resolution when in Nvidia Surround mode.

System: 6900k, 64Gb ram, Asus Rampage V Ed 10. Win 10 64bit, Aniversay upd.

GTX 1080 in 2-way SLI (single flexible sli bridge)

Nvidia 372.54 driver.

monitors:
Nec X555UNS (55") in portrait orientation connected through HDMI cables with DisplayPort adapters at the PC end.

The monitors accept 4k input but then scales it down to their native HD res.

In "Disable SLI" and "Activate all displays" mode there is no problem choosing correct resolution, but whenever i run "Configure surround" in Nvidia control panel, it comes up with a 10800 x ~3000 @ 24Hz resolution. You can imagine how slugish 5x4k gets even on dual GTX1080.

If i then try to manually pick 5400x1920 as resolution for the full Surround, screens goes black for a few seconds but ends up back on 4k per monitor.

A few rather obscure non-4k resolutions work - like 3840x1377 (1377x768 per monitor) and 5250x1400 (1400x1050 per monitor) (Portrait mode on monitors).

The Nvidia Control Panel is a very poor and buggy application in this 5 monitor setup!

I have tried using CRU 1.2.6 - in "Activate all displays" mode i have removed ALL resolution except 1920x1080 for all 5 monitors, 'no extension block', then sign out and in again, then "configure surround", but with the same result.

I also tried using Monitor Asset Tool, extracted an .inf fil from the monitor.
Looking through the file, i find only mentions of 1920x1080 and lower resolutions so i did not make any changes to the .inf file.
Then booting in "allow unsigned drivers mode", i update the driver for each monitor with the created .inf file to get an edid override.
Then when i get to the "Configure Surround, i still get the same 4k per monitor resolution (10800 x 3840 in total, 3840x2160 per monitor)

I have tried connecting all monitors to only DisplayPort, or mixed - some DisplayPort and some HDMI, and even DP+HDMI+DVI - though the cables from the monitors are all HDMI, but then with various adapters.

I have 3 of these computers, each with 5 of the large NEC monitors.
Same problem on all three systems. One of the systems have DisplayPort cable without any adapters directly from monitors to graphics card. Same problem on that system.

(I have also tried with two slightly older driver versions, same result).

I happily arrange with a finders reward for anyone who can find a solution to this

Best regards, Ola

Hi guys,

Need some help...

After buying a new monitor Asus mg248q and try to use the freesync mode, I see that my screen is slightly move from bottom to the top, leaving about 5 pixels in the bottom with a black border.

It doesn't fit the whole screen. If I switch off adaptative sync in the monitor ODD then if fit the whole screen, but I loose freesync.

I'm using Display Port cable and the latest Crimson Drivers 16.9.1.

Can someone help me?

Thanks in advance.

Basically I use the pc as htpc conected to my HDTV

So I use cru to fine tune the movies refresh rate... 23,976 etc...

So i don t overclock the tv and don t have to use pixel clock patches

My tv is 1366x768, Windows say native is 1360x768 but on the sheets says 1366x768!and with this resolution I get perfect 1x1 pixel

Everything is good my refreshes a very good Tuned I get audio from hdmi...
But everytime I restart the computer the resolution is changed to 1024x768, that is quite annoyng... because everytime windows starts I have to change the resolution l
Doe anyone knows why this happening? And how fix it?

Add additional resolutions to any monitor that is plugged in.

I work for a digital signage company as the product engineer. I have been put in charge of handling the "image" for our platform. We run our software application on Windows 7 Professional 64-bit, and use Microsoft Deployment Tools to handle our image builds.

In the past we have used VGA cables to run all of our displays. It allows for very long runs ~100ft, for very little cost, and has always been reliable. As we move into digital, we are having to deal with EDID issues more and more, especially with Ultra-wide monitors.

I am looking for a way, either programatically or automatically, to add needed resolutions to a monitor when it is plugged into the system. I have a bit of background in programming, but it is more script based (powershell, javascript, etc.)

Some of our legacy products use a 1360x768 resolution. In the past this has not been an issue as Windows will usually have this as a default resolution when using VGA. The problem now is that when EDID does not specifically have 1360 as a detailed timing. I would like to be able to add an additional EDID block for extra resolutions that we need.

We use a lot of signal extenders, and a LOT of them do not handle EDID very well. This would eliminate this problem as well.

We are going from VGA to HDMI, and one thing I would LOVE to do is put in an EDID block from HDMI that tells the system that the monitor does not support overscan. Not only is it an issue when using AMD video cards, but a lot of monitors will automatically adjust their displays to overscan automatically. It's just a support nightmare I am trying to avoid. Even if it is just from one end, it would eliminate that much more troubleshooting.

For the past two weeks I have been doing a LOT of research about EDID spoofing, .inf files, how Windows handles drivers... etc. I have tried to edit the default windows "monitor.inf" file with no real luck.

One of the issues is how windows deals with monitors that don't send an EDID packet. They're listed as a NonPNP-Monitor, and because of this do not have an EDID to override.

Does anyone know where these settings can be changed?

We are currently using older AMD 6350 video cards as well as newer W4100 and W4300 FirePro cards.

We are looking at moving to Intel, and I wanted to know if there were any caveats to this move as well. How well does intel handle EDID management, and can you emulate the EDID like you can with nVidia, and AMD?

Any help would be appreciated.

Can't set custom resolution on FBAS

Hey there,

I think its better to use an own Thread for this instead of asking in the CRU Thread.
The Situation is as followed:
New Windows 7 PC as replacement as a Signage/Media Center PC at one of my customers. The main monitor for administration is connected via VGA, the 2nd Monitor which should show the media content is connected via FBAS. For that purpose I built in some old Nvidia 8500GT with the newest drivers available.
Now the monitor from FBAS gets recognized as Non-PNP Monitor.
I need the resolution 848x480 for the connected tv.
I tried different ways, including CRU, to get that resolution somehow to work, but it only comes up for my first Monitor.
What am I doing wrong? Is it, with newer NVIDIA drivers under Win7, possible at all with a non-pnp Monitor to set such resolution? If so, please tell me how Smile

tl;dr
Windows 7x64 Pro, Nvidia 8500GT, can't set custom resolution on Non-PNP Monitor via FBAS.

Hi, I'm getting an error when patching the driver (372.90). It says "CryptUIWizDigitalSign failed: 0x12" then there comes another Text Box with "CryptUIWizDigitalSign failed: 0x800b0003" and then another one with "Failed to sign new driver file".

Does anyone know how to fix this?

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.

The other day i rebooted my pc and the image was no longer sharp any more

Whenever i look at it theres a slight blur and it looks like the pixels on my screen are larger than they were before, it looks like its a lower resolution scaled up, or its overscanned or pixels arent 1:1 or something like that

Anyone know what the problem is or how to fix it? It looks bad and gives me a headache

Hello everybody, new in the forums.

So I've been trying to overclock my monitor (Samsung t23b350) and failing. But i noticed that on a lower resolution i CAN use 75Hz. So my question is: If i can go 75Hz at a lower resolution shouldn't i be able to do it on all resolutions? I've tried the NVIDIA patcher, rebooting and then using CRU add a 1920x1080 resolution (default) with a clock of 75Hz (I even tried 61) but it didin't work. Am i missing something, or my monitor is not capable of overclocking?

BL3201PT 4K overclock

Hi There,

I've always wondered about overclocking my display but never looked into it, hence me now arriving here, I recently upgraded to a BenQ BL3201PT 4K monitor and love it. I have a GTX1080 overclocked and in the right game\settings FPS above 60 is easy enough.

So before I dive into overclocking the BenQ, I wanted to know if overclocking at 4K was any different to lower resolution monitors? I ask this because I notice there are very few 4K screens on the market with a refresh rate over 60 so I was wondering is that a limitation of 4K that manufacturers are aware of, and if I try to overclock mine should I expect to be aiming my sites lower? For example will I only achieve a few Hz over the base 60, or anything at all?

What is the normal cumulative increase when overclocking Hz? 2-3 at a time?

Blue, yellow colors are distorted at 75Hz@1080p

Hi!

I've bought an LG 23MP68VQ-P monitor. I have an AMD card so I enabled Freesync, but after that I noticed the blue colors are pixelated (like there is a grid drawn on them or something) at 75 Hz. If I lower it to 60 Hz it's fine again, I tried to experiment with custom resolutions and it's around 65 Hz when this issue starts to present.
What do I have to do ? I'm using with HDMI with amd R9 390.

Edit: It's very noticeable with some colors If I look closely, but not just blue, yellowish.

60hz mode:

75hz mode

Looks like the issue starts happening when I exceed 158-159 MHz pixel clock.

Dell P2217H EDID issue - Monitor or GPU?

November 19, 2016, 8:57 pm

Hi. I recently acquired a Dell P2217H. It has a maximum resolution of 1920x1080@60hz and 3 inputs: VGA, HDMI and DisplayPort.

Over HDMI, it works just fine at 1920x1080 as advertised.
However, over VGA and DP it only display available resolutions up to 1680x1050. To make it work at 1920x1080, I have to add a custom resolution using CRU (or through Nvidia control panel) on Windows.

With the little bit of knowledge I have, I decided to check the monitor's EDID. The problem is that the 1920x1080 resolution is defined in an extension block, and apparently my GPU cannot read the extension block through DP, only using HDMI. I was certain that this was a monitor issue until I read, in the CRU thread, that Nvidia driver has issues with extension blocks. And I only tested the monitor in 2 computers: My desktop (ASUS 1070 GTX) and my laptop (onboard Intel with a GeForce 840M, and I believe the VGA port is connected to the GeForce GPU).

My question is: Is this likely a monitor issue and I should try to have Dell get me a working monitor, or this could just be the Nvidia issue? And why does it work through HDMI but not DP or VGA?

Here's the output of edid-decode of the dump I made through HDMI

Freesync hack (hacksync?) results for Asus PB278Q

Hi,
sharing my attempt to Freesync hack with the CRU software on an ASUS PB278Q 28" 1440 IPS monitor.

TLRD: Freesync didn't work. Overclocking to 80hz over HDMI has been no problem.

Stock Hz is 60. Editing the extension to add Freesync option no problem. Started with a Freesync range of 35-60hz. Upon reboot, AMD driver showed Freesync active. However, using the AMD Windmill Test showed no visual effect of turning Freesync on or off. Vsync, however, did reduce tearing. With Vsync on, turning Freesync on or off had no visual effect.

I tried several Max refresh rates and Fsync ranges. No effect.

I'm not experienced with OCing/hacking/etc. I'm just leaving a record of my attempt.

Thanks for the software and for getting my Hz up to 80! I'll go for higher when my DDVI cable gets here.

Adjust V-Position (nvidia) LG31MU97

Hello,

I had the bad luck to damage top corner of my 4k monitor LG31mu97.

I was thinking that i can avoid that cracked part if i set a custom resolution 4096x2052 which works ok , my only issue is that i cannot adjust the vertical position of the screen, by default nvidia set cetered vertically, and i would like shift it down, so i don`t lose from both side when i made the resolution smaller....

I wanted to try with powerstrip but i have grey out the settings, cru does not let me set 4096 resolution...

any ideea what else i could do?

i run on windows 10, with gtx 780

(i suspect that i should change something in the custom resolution from nvidia timings but somehow i don`t know what)

Thank you
