Also I've tried changing it 120hz in nvidia panel again and it wasn't working. I've later realized that for some reason first I need to apply a 120hz profile. The highest one available is 1080p, so afterwards I edited resolution on that profile to 1440p and it works like it did before.

That's not a true 2560x1440. You're scaling down to 1920x1080, which is then scaled up to 3840x2160 by the TV, so it's being scaled twice. The NVIDIA control panel shows the timing parameters when you create the custom resolution. The active pixels is what is actually sent to the display, so if the resolution at the top doesn't match the active pixels, it's being scaled by the GPU. Windows will also show you the desktop resolution vs. the active signal resolution in the advanced display settings. Based on what I've read from searching, the LG B7 doesn't support 2560x1440 @ 120 Hz, only 1920x1080 @ 120 Hz.

Aww, damn it. Thanks for clearing that up. So I'll just stick to 4k/60 and 1080/120 for other occasions. Maybe you also know why other depths and colour profiles don't work even on 1080p 120?

The problem with HDR at 120 Hz is an issue specific to the LG B7. The LG C7 also has the same problem according to RTINGS.

Hi, i posted this before as separate thread but i see more people here so ill try asking, maybe someone can help me.

So i have Lenovo Legion GO Handheld, it has AMD 780m
Its 16:10 device and by default it came with x3 resolutions in windows settings and 3 resolutions in Lenovo Pop-up overlay
1600p, 1200p, 800p,

After windows update [I assume thats what happened], i now have a bunch of unnecessary 16:9 resolutions
I tried safe boot, driver cleaner > fresh driver, no help


these are the resolutions that appeared, they all 16:9:
1440p, 1080p, 1000p, 900p, 720p

I cant choose "hide unsupported resolutions" since it uses windows default driver and that option is grayed out.

Whats even stranger is that CRU in all its settings only shows single resolution 1600 x 2560 [its portrait display]
It doesn't even show the 2 others: 1200p and 800p so no idea where they coming from.

I also downloaded SRU, and chose delete all option, zero effect

What im looking for is either:
People that know where to delete resolutions in assuming windows registry [because i have a reg file thata dds 1050 resolution so i think they all hidden somewhere in the registry?]
Or help creating custom monitor.inf file with just the supported resolutions, also maybe its possible to edit the inf with monitor actual name from CRU so windows thinks its actual real driver? this way "hide unsupported resolutions" will appear
Also maybe someone know the registry location for "hide unsupported resolutions" to force this option? will be easiest solution

P.S. this display is strange, it just has 60hz and 144hz, i tried adding 120hz with CRU, it works but touch function gets disabled

I've just snagged a used LG B7 Oled in great condition, no retention or burn in. Just a tiny amount of pixels in the corner that fade to black once it heats up, which is probably an overheating issue that I could solve by taking the shell and getting a some fans or something.

So anyways, it's HDMI 2.0 only. I'm wondering what useful I can do with it.
I want to get 1440p/120hz, but when I enabled it through Nvidia panel HDR doesn't work properly, screen is overblown, darks are gray and I think it's stuck at only 8bit rgb.

What would be the best resolutions, colour depth and format for an OLED?
And how do I even change colour depth and format in CRU?

Hi,
I been OLED "monitor" user since 2016 C6P>C9>s96B

For your model, if you want 4K + HDR you must set it to 4:2:2 + 10bit or if it doesn't work 4:2:0
If you run 8BIT and turn on HDR thats not real HDR, its dithered HDR and you just lose all of its glory, especially on OLED which is 10bit

For movies and video games, there is zero visible difference when 4:2:2/4:2:0 is enabled
The official HDR standard for movies is 10bit 4:2:0, thats how UHD blurays encoded
So it looks ok, you have nothing to worry, the only issue is if you decide to keep it for windows youll have text a bit strange, but if you manage to use 4:2:2+10bit its not that bad even in windows.

Just dont forget to enable game mode and honestly the 4:2:2 mode 60Hz 4K + HDR was great, i been gaming like that for years until C9 came out with HDMI 2.1, had no reason to upgrade to C7/C8

The 9 series is the first with official 1440p support, before it had no offical 1440p

Hello ToastyX,

first of all, thank you very much for your work and effort to create the CRU tool.

I would like to use the latest version 1.5.2 and downloaded it from your site.

As always, I scanned all downloaded files via virustotal.com before I executed them.

By this, I discovered that some of your executables are reported as "suspicious" by some scanners at virustotal.

For example the "reset-all.exe" is flagged as "W32.AIDetectMalware" by Bkav Pro and
"Generic.Malware" by TEHTRIS.

The "CRU.exe" is flagged as "Trojan.Malware.300983.susgen" by MaxSecure.

Most probably they are false positives.

Do you know why these engines detect these potential threads within your executables?

Additionally filescan.io e.g. reports for "CRU.exe" (version 1.5.2):

--------

Unexpected was, that the "behaviour analysis" by virustotal.com reports that "CRU.exe" connects to the following IPs:

And performs the following DNS Resolutions:

The "behaviour analysis" by virustotal.com reports that "reset-all.exe" connects to the following IPs:

I can't understand why these files have to connect to (so many) internet servers.

I would have expected that there's no traffic at all.

Why is this the case and what data is beeing transmitted?

It would help me a lot to understand why there's so much network traffic in order to know if it is intended like this and to know what data is received/sent from/to my computer if I use your tool.

I hope you understand these questions. Most likely you also would scan/analyse any downloaded software before executing it.

As stated above this all are most likely false positives and there's probably a good reason why your tools contact the above mentioned IPs.

I just want to understand why this is the case.

Thank you very much!

Because they are dumb. There is always some false positive by some obscure antivirus or some automatic heuristics algorithm. Even when I go through the trouble of reporting the false positive (and some of these companies are hard to contact), some new one eventually pops up a few months later, so I don't bother unless it's a major antivirus program. https://blog.nirsoft.net/2009/05/17/anti...evelopers/

None of the included executable files make any connections or transmit any data. Those are mostly Microsoft IP addresses and DNS servers. Likely they are recording all IP traffic when running the program including whatever Windows does in the background. You can try any program such as C:\Windows\notepad.exe and it will report IP traffic.

Hello everyone! I'm new to CRU and I would appreciate if someone could help me. I'm trying to get rid of the Windows stuttering issue (because of the NtGdiDdDDIGetDisplayModeList) and I want to delete all resolutions besides my native one, 1024x768 and 1280x960. When running CRU it showed me only very few resolutions (the standard ones, under Established Resolutions, the native one and 1024x768). I have also checked extension blocks and I can only find my native resolution. Then I run SRE and there were many resolutions which I deleted. After that I checked NV_Modes in registry. Then I have looked in nVidia control panel and in display settings and there are still two resolutions (1920x1080, 1280x720, 1176x664) . How I can get rid of them? Why CRU only showed me few resolutions in comparation with SRE? Thank you very much!

CRU shows you the resolutions defined by the monitor, and SRE shows you the scaled resolutions defined by the GPU's driver, so they will be different. Is there a TV resolutions data block in the extension block? That's the only other place I can think of that would have 1920x1080 and 1280x720. The driver might also be adding other resolutions hard-coded in the driver such as 1768x992 and 1176x664. I haven't found a way to remove those. I don't remember those being in older drivers.

I really appreciate the explanation, I understand now. There is nothing there. I have one default extension block with no resolution and one named Display ID 1.3: 1 data block. This one is having my native in Display ID 1.3 and Display ID 2 with 2 different refresh rates. By the way, I will break something if I delete this extension block? I remembered that in CRU and also SRE, I deleted 1920x1080 resolution, but still appears in AIDA at video modes and control panel / display settings. Thank you very much!

Later Edit: One more question, please. If i deleted my native res from SRE and I still have it on CRU is there any difference?

Hi, I have a lenovo idea pad 5 with intel xe graphics and a 60 hz monitor. When i create a new resolution and try to use it my screen turns black and goes back to 60hz. I thought it was because my monitor couldn't handle it but then I tried to set it to 50hz and it did the same thing. I've tried everything but it stays on 60hz and won't move up or down in refresh rate. Can someone help please.
