Custom Resolution Utility (CRU)

[polopretress]

Hello ToastyX.
First, thank you for this software.
Second, sorry i am not US native speaker. Then some possible issues in my explanation/comment can be done...
Third, i apologize for my (certainly) long post but i need to define the context first.

I am a HTPC user and my need is only to build a custom resolution that will be used in priority against the standard EDID coming from my receiver (Video Projector or TV).
So no need high FPS. Only standard FPS for movies ( 23.97602.. / 24.000 / 50.000 progressive) but perfectly accurate to have "no drop frames rate" (i accept 10/12 hours ...)

In this spirit , i have created a calculator under excel that helps me to give the "ideal" combinaison for setting up a custom resolution (pixel clock, total pixel H/V, Front porch H/V etc... and taking into account the clock deviation given by madVr that i am using for enhanced video rendering).

Few years ago (2), i had an ATI GPU and this was very easy to create "exotic" custom resolutions that differs a lot from the default settings to obtain the perfect display clock. No issue for me directly in the driver since the pixel clock can be modified easely without any blocking warning. (not the case for nvidia cards...)
With this card, i have tried also to use CRU without any issue but it was useless for me since ATI driver accepts directly my settings.

When i say "without any issue", it is also because i have found that on some projector /TV that was rejecting my settings , it was easy to "work around" by creating a custom resolution at the double of the targeted resolution ( ie : 47.952 for 23.976) and set it as a 23976 resolution.
Then the EDID of the receiver is not followed and my settings is applied. (i am not sure i am clear enough ....)

OK, then i have switched to Nvidia GPU (GTX1080) and this driver get me crazy because it did not accept what i was able to do with ATI...
Then i tried with CRU but without succes for all devices receivers ( some of them was working fine and some others did reject the settings.. for example Sony and JVC VP but working great on Epson !!! )
When i say "did reject", it is mainly because after a reboot, the EDID of the receiver was tacken instead of the custom resolution (so no black screen linked to my custom settings but simply ignore...).

At that time , i was only using "detailed resolutions" tab in your software (1.3.1) to create a custom res.


NOW. TODAY.

I have seen some evolution in your software (1.4.2). Maybe a possiblity to clean my issue that i still have with nvidia driver. (i have found a setting that is correctly working but not perfect as i expect). only 23.97590 for a target at 23.97602.. and i want more accuracy that is able to provide me my home calculator (6 digits behind the coma) even if it will not change the world .
In addition, that works correctly for me but some others users (contact of me) cannot succeed to create custom res with nvidia driver and their receiver. And my goal is to find a common method that works fine for any of receiver and GPU card.

My first question (of newbie) that is not related to my problem is :
Shall i use "restart.exe" or "restart64.exe" to override edid if i use win 64 bits ? (i guess it is restart64.exe but need to be sure because your first page is talking only on "restart.exe")

My others questions are :
- I have a contact that has succed to create a custom res by using "Extension Blocks" / 'DisplayID" / "detailed resolutions" that i have never used. Do you confirm that it could work better than using the standard tab "detailed resolutions" ?
- And, when you are selecting "displayID" you must choose between " detailed resolutions" and "titles display topology" ==> i suppose that the second option is not important for my need ?
- in fact, is it better to use "DisplayID" or "CEA-861" for my need ?


Thnak you !
