You might need active adapters for Surround to work with three monitors. Hi ToastyX I attach the adaptor picture here. I use three of them connecting to my RTX3080, it is just a normal cheap adaptor. I am also curious that the problem comes from the adaptors. Therefore, I am looking forward to get two 2.1 hdmi to testing two screens surround (my GPU has only 2 hdmi ports) If it works, it means the problem comes from adaptors right? If it work, I plan to use 2 hdmi port and 1 display port to run triple screens. Therefore, I have to find one more reliable adaptor. From your experience, can you suggest the adaptor (display port to hdmi) that works with NV surround? I find one from Club3d (display port to 2.1 hdmi). I am not sure it is gonna work or not. Anyway, thank for your help, I am really appreciated |

RE: Custom Resolution Utility (CRU)
Hey ToastyX - I am kinda curious on something with the new 360Hz monitors;
There seems to be not a single 360Hz resolution in the entire extension block displayed, the VRR ranges are indicated as 1-255 as well and lastly, why does detailed resolution showcase 60Hz and also I am not able to create a 360Hz profile no matter what. In windows my display states as 360.113 - but through NVIDIAs custom resolution in NVCP, I changed my refresh rate to a round 360 and had it work out with CVT Reduced Blank timings set to Auto. The reason why I am primarily curious about all this, is because I've seen many manufacturers out of box at default run something like 239.760 for the 240Hz monitors etc, whenever I changed this to a round 240 with LCD Native in CRU - I'd have a very different game feel when utilizing the monitor. It was as if it got a lot, lot more smooth/responsive/fast. Odd, just curious if you had any answers or knowledge regarding stuff like this or if it's pure placebo. (also curious about the 360Hz thing, maybe CRU isn't supported yet for those monitors out of the box information?) |

I didn't know what that was for because I don't have the HDMI 2.1 specs, but your comment about FRL helped me make the connection. CRU doesn't have a way to edit any of the HDMI 2.1 features yet, but it can import the changes. Hi, I have tried your file and it works great at 4k 12bits 120fps, but as soon as I apply the file in CRU and run reset64, the "enable g-sync" option from the nvidia control panel disappears, almost as if the gpu driver does not detect the display as g-sync compatible. I just attached the original edid exported using cru. |

RE: Custom Resolution Utility (CRU)
LG CX
4K + 120hz + 4:4:4/RGB + 12 Bit = Lose Gsync Exactly this i can confirm .. a Guy on Reddit made a Post about that CRU Profil from you ToastyX https://www.reddit.com/r/OLED_Gaming/com..._on_lg_cx/ But when i Import the CRU Profil for 12 Bit for the CX the Option to Activate Gsync in the Nvidia Control Panel are gone. And a Freesync Line ( 24-120 FPS ) appears in the "Detailed resolution" List in CRU ... this Freesync Line is not there with the Original Profil of mine 48CX. 4K + 120hz + 4:4:4 + 12 Bit Works ... but than Gsync Compatible no longer works. As a Info : LG C9 ( 2019 ) has Full 48 Gbit/s Bandwidth LG CX ( 2020 ) has Officially only 40 Gbit/s Bandwidth Officially Max. Settings : C9 : 4K + 120hz + RGB/4:4:4 + 12 Bit ( 48 Gbit/s ) CX : 4K + 120hz + RGB/4:4:4 + 10 Bit ( 40 Gbit/s ) |

Try letting Unigine Heaven run overnight: https://benchmark.unigine.com/heaven With CRU in effect and run free Heaven about 9 hrs. overnight zero failures monitored with hwinfo64. Max GPU temp 74c, CPU (highest of CPU sensors) 65c Ran Heaven benchmark after stress test: https://drive.google.com/file/d/1lFviPHw...sp=sharing BTW Lenovo says new Firmware in testing for my Y27Q20 monitor - this monitor has known black screen issues past year w/10xx series nvidia cards (I have 3070 but still may apply). Since CRU clearly masking this issue (and assuming display EDID can change w/new firmware). Could new monitor firmware be my fix? BTW sufficient conditions for failure seems web app/software specific esp. Youtube - As you know Youtube video has disparate resolution options for other device drivers firmware to properly navigate. Also w/CRU in effect monitor audio EDID disabled - possible audio EDID settings conflict w/PC?? PLUS, monitor cannot use HDR 10 bit (limited to SDR 8 bit) w/CRU in effect. Keep me straight please!! :-) Ryzen 5 3600x | RTX 3070 FE | MSI Tomahawk X570 | Crucial Ballistix 3600 CL16 4x8 gb | Seasonic Gold+ 750w | Lenovo Y27Q20 | Windows 10 Pro |

RE: Custom Resolution Utility (CRU)
Hi. Could you help me with my problem please because i can't sleep anymore Wink
I have a laptop with two graphics one is: https://ark.intel.com/content/www/us/en/...0-ghz.html and another is Geforce gtx 760M. I have a monitor connected Aoc U2879VF and the problem is optimus which force me to use integrated graphics resolution to 3840X2160/30Hz and i would like to 60Hz. I'm using HDMI cable. Have tried your app to set up custom res but no success. Can you help me please? Thanks that's my 2 post but not sure where should be so i will delete first one |

The problem isn't the adapter itself, but the GPU might have a limitation that won't allow Surround to work with three screens with passive adapters, although I can't find any information about such a limitation with NVIDIA cards. I know AMD cards have such a limitation with Eyefinity. Passive adapters also won't allow the full HDMI 2.1 bandwidth. The Club3D adapter should work since it's an active adapter. |

NVIDIA also ignores overrides with default extension blocks, so you'll have to delete the default extension block and create one manually, but that might disable VRR. I have an idea to read the extension block directly from the monitor instead, but I'll need someone to test it because I don't have a monitor with 2 extension blocks. Will you be able to run some tests? The problem with the range limits is they keep coming up with new ways to specify the refresh rate range. I know of three different methods (EDID range limits, AMD FreeSync data block, HDMI 2.1 data block), but your monitor seems to use another method. I don't know why because the EDID range limits can go up to 510 Hz. It might be in the DisplayID extension block, but I just checked the DisplayID standard, and it can't even define a range beyond 255 Hz. |
