If you increase the pixel clock by just 1MHz, you are exceeding what the standard is designed to do, full stop. It will probably work, but nothing whatsoever is required to support it.
of course they aren't required to support it, but obviously it DOES support it, if you can change the refresh rate above 60hz once you are actually IN windows

And? Let's say I have a laptop that takes 12V in from a charger. I lose mine, so I borrow a friend's. It fits, but it's 19V. My laptop fries because the charging circuit just took >50% higher input voltage. Whoops.

Just because the software les you do something doesn't mean it will work. My BIOS lets me run my CPU at x63 and like 2V. (Okay, I'd need a -K processor to actually do that, but shut up the example works.) Does that mean I can achieve 63x100MHz? Nope! Does that mean the CPU will handle 2V and survive? Nope! All it means is that the option is there.

You need to learn the difference between 'it works' and 'its supported'. The two are not mutually inclusive.

I can connect my wireless router to my modem with an ethernet cable, or I can connect them with an ethernet cable made of a pair of spliced RJ11 phone cables. It works. Is that supported? Not a snowball's chance in hell. If I called my ISP up and told them it wasnt working with that cable, they would laugh at me for doing it. Same if I put a third party part in a vehicle and it didnt perform properly. Same if I mod a game with a third party mod.

DVI 'supports' up to 60hz at 1440p with dual link DVI. You can tell the monitor to run faster then that, and DVI will push it, but that is not officially supported. Just like running 4k60 on dual DP1.0 ports. Monitor manufacturers did that, but it wasnt officially supported by the displayport standard, and surprise surprise it had problems. So, 17 years after DVI's introduction, if a GPU breaks this ability to run out-of-spec, you are SOL. Either use a modern connection or stop running out of spec, and all will be well.

Anyone who honestly believes it is nvidia's job to fix a monitor that is being run on a resolution it's inputs do not support has a couple screws loose. That is not nvidia's job, that is the job of screen OEMs.

From my understanding, running these out of spec (overclocked) would put the strain on the monitor, not the GPU, correct? So there is no risk to the GPU, only the monitor?

I completley understand the difference, I never said it was SUPPORTED, but it has worked, and still works after windows boots perfectly fine, there's no reason to limit it whatsoever unless they just want someone to buy their gsync monitors, which honestly wouldn't surprise me, I don't quite understand your corporate worshiping though, and Nvidia will fix it, almost guaranteed.

I know right. Nvidia card has a problem with DVI connector = buy a new monitor, not NVidia's issue. AMD card does not have a DVI connector = AMD expects people to buy new monitors ? Crazy AMD.

Custom boards can include a DVI connector.

Some gamers using our latest Pascal based GPUs connected to high refresh rate monitor have reported that the highest refresh rates or resolutions are not available when connected using DVI. This behavior is due to limited bandwidth available on the DVI cables. NVIDIA recommends that these high performance monitors be connected using DP instead of DVI. DP natively has much higher performance and will support the full capabilities of modern monitors.

In addition, NVIDIA is updating our driver to attempt to run at higher clocks on older DVI cables and enable all monitor modes. However, this high clock behavior is beyond the cable specification and depending on cable and monitor quality, may be unstable or non-functional.

Yeah, that sounds like a cop-out. The same cables that worked on the 290X/980/980 Ti/etc suddenly don't work any longer?

That doesn't even make any sense, they DO work with Pascal, they just don't work on BOOT, as long as you are already booted into Windows, you can then change your refresh rate to however high your monitor/cable will allow
