The monitor advertises 4K @ 60 Hz in its EDID both in the base block and as TV resolution in the CTA-861 block and even additionally via DisplayID. However, this would require a pixel clock of 594 MHz. I'm not sure if the HD 6000 in the Broadwell i5-5250U processor can even do that. Especially under Windows 7. Back then, DisplayPort was limited to 540 MHz even on dedicated Nvidia cards, even at color depths of less than or equal to 8 bpc.

The monitor also advertises 2560 x 1440 @ 120 Hz at 497.95 MHz pixel clock (CVT-RB). Does that work?

[浅闇白子]

it can work on 2k120hz.

[浅闇白子]

The same is true with win10

[MUC]

According to the monitor, the pixel clock is:

• 1920 x 1080 @ 120 Hz = 297 MHz
• 3840 x 2160 @ 30 Hz = 297 MHz

Is 2560 x 1440 @ 120 Hz offered as a selectable mode? If so, and if it works, then that would be proof that the HD 6000 can handle at least 498 MHz pixel clock. It would also be proof that the Detailed Timing Descriptors within the CTA-861 block of the EDID are being processed.

According to the NUC5i5RYB - Technical Product Specification, this should also be the case:

Please confirm or deny. This will help determine next steps.

[浅闇白子]

It can run on 2560x1440 120hz

[MUC]

Please try as follows, it should work on Windows 7.

• Download the EDID file attached (EDID_Samsung_Odyssey_Neo_G7_mod_01.txt)
• Download Custom Resolution Utility (CRU)
• Run CRU.exe
• Make sure the active EDID is SAM72AA connected to your NUC
  
  
• Close CRU with OK and restart the computer.

Note:
All changes made with CRU can be undone if necessary by running "reset-all.exe" from the CRU download package and restarting the system. You can find more information about this tool on the linked page.

If after this change 4K @ 50 Hz (495 MHz) can be selected and works but not 60 Hz, then the pixel clock of the HD 6000 is probably limited to below 600 MHz.

[浅闇白子]

WOW！YES！I ues your method，it can work on 3840x2160 51hz，It‘s already quite good！ Thank you very muck！

I serched the neo g7 monitor manual，CEA 3840x2160 60hz can work on 594 Mhz ， Perhaps HD6000 can only runBetween 500hz and 594Hz？Is 3840x2160 60Hz sure not working？

[MUC]

• According to the manual, the monitor wants CTA Video Timing for 4K @ 60 Hz, i.e. 594 MHz = 18 Gbps (CTA = Consumer Technology Association)
• For 2560 x 1440 @ 120 Hz it demands VESA CVT-RB (Video Electronics Standards Association Coordinated Video Timing - Reduced Blanking)

It is quite possible that the monitor can also accept and process 4K @ 60 Hz with CVT-RB. That would then be the 4K @ 60 Hz that the NUC specification refers to: 4K @ 60 Hz CVT-RB = 533 MHz pixel clock. This is also the common signal via DisplayPort.

Please try version 02 from the attachment. You can simply import it using the method described above, it will replace the existing one.

[浅闇白子]

I try this 02.txt,  the  monitor still work on 3840x2160 51hz. HD6000 probably can't run 533Mhz.

[MUC]

Based on EDID version 01, you can gradually work your way up to the maximum that the HD 6000 can output.

• Reinstall EDID version 01 as described above.
• Restart the computer.
• Run CRU.exe and proceed as follows:

(4) Select "Native HDTV" as the Timing and all parameters below will be automatically calculated according to the CTA-861 standard when you enter the resolution and refresh rate. If you want to try VESA CVT-RB, select "CVT-RB standard".

(5) Increase the refresh rate to 54 Hz, for example

(6) The automatically calculated pixel clock will then increase to 534.6 MHz for this (Native HDTV) example

• Close all CRU windows with OK and restart the computer.
• Try to see if the changed mode works. If it doesn't and the screen remains black or distorted, Windows should return to the previous mode after 15 seconds of no input.
• Start again at the beginning and try a different refresh rate.

This approach is not very convenient but I don't think you can do more than that.

[浅闇白子]

After trying, it can finally run 4k57hz under CVT-RB standard with pixel clock  505.94Mhz. I think that's the limit of the h6000.

it can run4k59 under Native(pc) with pixel clock 524.4Mhz.
