Thanks for the reply; I think I understand now. It's just unfortunate that enabling testsigning interferes too much with day-to-day stuff, so I have no choice but to either run a second machine or dual-boot. I suppose I could create one custom resolution and force everything to run at that just to avoid the shimmering and dot crawl... but is creating a 240p 15kHz signal possible without the custom drivers?

That thing is actually a direct ripoff of an older pre-GreenAntz design, that my mate published on github in 2018 before we decided to make a better "sellable" version. I told him this would happen back then, and surely it did.
Anyway, if you are happy then that's great and some Chinese dude is richer. The quality is mediocre in many ways (yes I bought one for testing, inspection, comparison). Know that the newer GreenAntz v1.94 is significantly better - especially colour brightness, saturation and consistency.
Back to your other issues, maybe you should give CRU a try. You won't get the switchres magic, but at least you should be able to get 240p.

Could you please tell us which day-to-day stuff is interfered by testsigning? I'm aware of anti-cheat systems in Steam, etc. but nothing else, but of course I'm not in gaming and I'm probably unaware of other issues. I've run my production pcs with testsigning enabled for over a decade with no problems at all.

Check this thread: https://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=326
Note: the procedure in that thread uses CRU to add extra modes to the EDID. I'd say (but haven't tested) that all the process could be done through vmmaker alone, without CRT, by checking tick "Add modes from modelist" in the EDID emulation tab.
The logic here is that the low resolution limit in stock drivers is bypassed through the EDID, but instead affects custom modes added through AMD's api (which is why the patched drivers are needed).

I program a lot of automation in AHK, mostly for window arrangement. The one I wrote for Steam specifically relies heavily on the Steam browser protocol, and having testsigning enabled adds an inexplicable delay to those commands, which defeats the purpose of the program. And of course some games won't run because they rely on anti-cheat programs that won't work in that mode.
And thanks, I'll mess around with CRU although from what I understand you need the custom driver to remove the limitations on how many custom resolutions you can add.

Edit2: Tried this again on my rebuilt dedicated machine and this seems to be a possible problem with UltraMon, because even though I couldn't make it pick 320x240, Switchres was able to, as was Windows display settings. Which is weird because I was able to make UltraMon switch to that resolution before.
Edit: Nevermind, I appear to have solved the issue by simply using my previous custom preset instead.
I'm having another issue going the standard route with a new TV. I had CRTEmudriver running great on the RCA TruFlat 27F522T after making a custom preset for it, but the component inputs died on me and it suffered from the infamous flatscreen "side stretching" AKA "WEGA wobble" especially noticeable in sidescrolling games.
I lucked out and I found an Orion sub-brand "Dynex" set which has a curved screen and component inputs. It appears to be identical to the Sansui DTV2798.
I'm able to get custom resolutions added to it using the NTSC TV preset, I'm getting very strange behavior. When I attempt to set it to 320x240 landscape progressive, it switches to 256x448 portrait interlaced. I've attached images of the display settings using UltraMon.
I'm connected via DVI to VGA adapter and then to a standard RGB to YPbPr converter, the same one I was using before, so it really shouldn't matter what television set is getting the component signal, right?
The only difference is that I'm testing using my main PC instead of the dedicated machine I had connected to the TruFlat (the mobo crapped out and I'm in the middle of replacing it) and I'll test again using that, but both systems are using the exact same model of HD 5450 as the secondary card, and both are running Windows 10 64-bit.
