Running DDU may not be as necessary nowadays but it's still a reasonable troubleshooting step. Do you get the same problem cropping up if you have Windows sleep the display instead of turning it off with the power switch? I mean, like have the screensaver set to kick in and sleep the screen instead of having an actual screensaver?

I don't think it's windows not being able to render to the framebuffer -- I suspect that if you got things set up so that the monitor was never on it would work fine. It's the transition from real monitor to the virtual monitor that is likely messing up the software. Also you might want to look into whether the GPU is downclocking in response to no monitor, that's another thing that might be happening. I run 2 monitors, and the crappy asus one that's my primary is DP. It loses connection pretty frequently just from the monitor being put into power save, not even hard power off. So when that happens, all the windows get shifted over to the secondary 1680x1050 monitor and it fucks up the window sizes & positions. I ended up writing some custom AHK to save & restore window positions because it's so goddamn frustrating.

Yeah Displayport sucks in that regard, same way you can't turn off you monitor when running a Steam link when you could in the past with HDMI. DDU might be a placebo, but it sure as poo poo fixed some of the issues with my computer just rebooting after going from a 1080GTX to 3060GTX.

It's the monitor doing power saving wrong. In some cases you can fix the behavior by turning off certain power saving options on the monitor itself. Either way, the monitor is explicitly telling your computer that it's disconnecting and the DisplayPort spec specifically says not to do this, but a lot of monitors apparently use a broken controller or something that does it this way anyways.

Windows literally still keeps code around for the 1995 version of SimCity to still work, at this point they could add a workaround for so many DP monitors having this issue.

BaronVanAwesome posted:Like specifically the code is for SimCity? They specifically added code to Win95 that changed how Windows allocated memory if Sim City was running, because Sim City was written for 3.x which handled it differently. No idea if that code is still part of Windows but I wouldn't be surprised if it was, you still can't name a file "con" or "nul" after all. Here's a write up about it: https://www.joelonsoftware.com/2000/05/24/strategy-letter-ii-chicken-and-egg-problems/ quote:Jon Ross, who wrote the original version of SimCity for Windows 3.x, told me that he accidentally left a bug in SimCity where he read memory that he had just freed. Yep. It worked fine on Windows 3.x, because the memory never went anywhere. Here’s the amazing part: On beta versions of Windows 95, SimCity wasn’t working in testing. Microsoft tracked down the bug and added specific code to Windows 95 that looks for SimCity. If it finds SimCity running, it runs the memory allocator in a special mode that doesn’t free memory right away. That’s the kind of obsession with backward compatibility that made people willing to upgrade to Windows 95.

With the same monitors, I've have this issue with one PC but not the other. One has an Intel iGPU, the other is using an Nvidia graphics card. So drivers seem to play a role as well. Also, with the exception of my Asus monitors that have the option to disable "deep sleep", I'm pretty sure almost all monitors do the "wrong" behavior of completely powering off.

How do you propose that works? The monitor is literally turning off the "there is a monitor attached" signal. The system sees nothing different from if you physically unplugged it. There is no possible way to fix this from the PC side, it's purely a flaw in the monitor. You could bodge it for some people by telling the system to ignore disconnections for this monitor, but that opens up its own can of support worms when people inevitably enable that feature, unplug the monitor, then lose windows to the void.

So in the event that I've lost a monitor, I press win+p and click "this screen only" on my other monitor. (This will never happen since it's a very desktop-oriented way to think about screens, while win+p and the entire way that windows responds to monitor dis/connection is oriented to laptops.)

Self-replying but you can actually change the virtual display size that Windows swaps out too upon DP disconnection, the resolution is under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\Configuration\Simulated.

The Simcity fix mentioned earlier is there because while the bug is entirely in the Simcity code, it wasn't exposed until Windows 95 came along and actually cared about the memory area Simcity was accessing. From the perspective of the user their game would have worked just fine until they installed Windows 95. That gave Microsoft reason to care about someone else's problem. That doesn't apply here, these monitors are broken on every computer and every operating system that has a concept of hot-plug monitors.

A lot of TVs and AV receivers like to turn off the presence signal when switched to a different input which causes the same sort of behaviors, and in the end you can sometimes bodge around it depending on your exact use case but there is no universal solution other than "get new hardware that doesn't do this". wolrah fucked around with this message at 16:52 on Mar 9, 2021 |

Got a kind of weird request/desire: MSPaint on ancient windows, 3.1 I suppose, had a very limited colour palette. If you picked a custom skin tone for example, and paint-bucketed an area or drew with it, it would display as a sand colour with dots of red or whatever dithered to kind of make that colour. Was that a windows thing, or just an old lovely limited monitor thing? The closest way I know to achieve this effect is just exporting dithered pngs with super limited pallettes, but that's not quite the workflow I'd want to mess with here. Just hoping it's an old paint thing I could perhaps acquire and use now, if not, if anyone's got any ideas how to fake it with photoshop or something else, that'd be cool too.

Yeah, it was dithering to account for the limited color palette. Dithering algorithms today will take current color depths into account so you would probably have to do something wholly artificial.

The missing ingredient in those techniques is differing patterns. The old amiga-era programs and their PC equivalents were limited to (I think) 6 pre-defined colours, (RGB + CMY) so you could never be blending 5 shades of blue together. To get more than 2 shades of blue to mix, they then used differing patterns to mix them Hard to find many examples of what they produce, but in the Corel draw 2 splash screen you can see the same 2 colours mix together in a spotted differ, and then a hash-pattern. There were also star patterns, cross-hatching and others. If you check the colour palettes at the bottom there, you'll see colours mixed from some of these patterns.

Plus I have no attachment to it besides liking how it looks, we had apple ][s at school and those colourful candy ones they did for a while, but I do have a connection with the old windows art side of things. Looks like PcPaintbrush might actually be able to get the macpaint and old-dithered effects I was wanting to play with. The hd-index tutorial was interesting too, I like how learning some blender is paying off in all these little random places, like, I 've never used a color-ramp in photoshop before, didn't know it existed before using them a bunch in blender nodes.

Deluxe Paint supported a 32 colour palette arbitrarily assembled from all the colours supported by the Amiga, so you only had to dither if you needed more than that. Like this example where there's a lot colours spent on skin and fur with some dithering for additional shading and in the background where the eye colours were reused.

Our local hospital has been using Fuji Synapse PACS (archive system for medical images) for ages. The Fuji system opens the images in Internet Explorer so doctors can view them. After having to upgrade from win7 to win10 there has been problems with the image viewer. Occasionally multi-monitor support breaks, IE starts to hog CPU cycles for no reason, toolbar buttons become non-operable and turn into a black box, IE steals focus instantly from all other apps repeatedly until killed etc. IT has no idea. The provider who sold the PACS system doesn't give a F. Hospital's PACS support people have no idea. So far the doctor has been restarting the PC when problems arise. It works for some time until it breaks again. I realized that by killing all iexplore.exe processes simultaneously and then trying to open the patient's medical images "solves" the problem. On range from stupid to very stupid, how stupid it would be to make some kind of bat, macro or something else which kills all iexplore.exe processes simultaneously and put it as a button to task bar or something? If the processes are killed one by one from task manager the iexplore processes just keep respawning and problem persists. We are moving to a new PACS from Sectra in 2 months so the interest to figure out and really solve the problem has beeen zero. Ihmemies fucked around with this message at 12:06 on Mar 10, 2021 |
