You can just add it back, or you can reset it as detailed in the first post:

DVI doesn't need anything special. You only need the first detailed resolution for the native resolution. Everything else is optional. As long as you don't have 24 Hz defined anywhere and you're not using the default extension block, 24 Hz shouldn't exist.

Thank you but how do i get into safe mode with no screen but just a black screen saying to reset my resolution ? I also had a typo in my first post. I clicked delete all and not just delete.

This is also mentioned in the first post:

If you don't have a recovery drive, press and hold the power button to shut off the computer while Windows is booting. Doing this twice should give you recovery options that you can use to get into safe mode: Troubleshoot > Advanced options > Startup Settings > Restart
I feel like you didn't read the first post at all. I included restart.exe to avoid this type of situation. What happened after you ran restart.exe?

I ram restart.exe after every new detailed resolution. Then i pressed delete all thinking it would delete the ones I made. Now is there anyway I can get into safe mode.

I don't know how I can help you if you're not even reading what I wrote. I told you how to get into safe mode. If you read that part and are having trouble, then tell me what you tried and describe what's happening. Did you try booting from a recovery drive? If you don't have one, did the power button trick not work?
So i tried the power button trick but it didn't work. I don't think a trick from 2012 would work on a 2017 PC anyway. I am still getting this msg. If you have any other form of better communication please let me know. Any help is appreciated

It should still work. I just tested it to make sure. Do you have a reset button on your PC? Press it as soon as you see the spinning dots. Do this twice and it should boot into the recovery menu.

If you can't get that to work, do you have a Windows installation drive? See method #5: http://www.digitalcitizen.life/4-ways-bo...windows-10

If you don't have an installation drive, you should be able to create a recovery drive from another PC (method #4) and use that to boot into the recovery menu.
I've been using CRU for a couple of years now. I have few questions.

So using NVCP, CRU, Nvidia Pixel Clock Patcher and a poke method I managed to overclock my monitor from 60 to 76.979 Hz. But there are 2 settings(lowest and highest numbers) I ended up with:

[Image: 9lOKyvm.png][Image: AiFhi0T.png]

Both look identical to my eyes but I am pretty sure first one with lower timings is faster than the second one by about 10-20ms. I used humanbenchmark.com to test but difference is smaller than deviation error. In total going from 60 Hz on default timings to 76.979 Hz on lowest timings I think I god rid of about ~40 ms latency in total. Can you confirm which settings are better? Which polarity set is better in terms of lag? -/-? -/+? +/-? +/+?

Maybe some settings are the best to be as low as possible and the other as high as possible and both of my sets of settings aren't the fastest ones possible for my monitor Philips 273EL(MonInfo log)? It has DVI-D and D-Sub sockets. I use DVI-D(Single Link) cable for my monitor. Is DVI-D is actually better(in terms of latency and overclocking abilities) than D-Sub?

Can you provide some names of books or links to articles or any information that can help to understand why first settings are better than the other one in this case(or vise versa if I am wrong)?

Also, I can go as high as 85 Hz(I have to use a little higher timings compared to my lowest values) and it 'works' fine without video artifacts, but once I go over 76.979 Hz, it starts to show a message from my monitor(on top of the working display behind the image) every ~1 minute for ~15 seconds saying:
Quote:Attention
This is 85 Hz overdrive
change computer display
input to 1920x1080 60 Hz

Is there any way I can do something to my monitor(like disassembling my monitor, taking out controller, patching few bits to not ever show any kind of menus) to never show this message? I believe I also read few years ago that it turns monitor off after 10 minutes of using monitor in this mode.

PS I know how to boot into a safe mode, Toasty Big Grin
