Revisiting Auto-Scaling

[ColdNose]

Hi,

I've searched all the posts I could find on this topic:
viewtopic.php?f=5&t=21264
viewtopic.php?p=175136#p175136, and I believe the latest attempt:
viewtopic.php?f=2&t=21142&hilit=NoAutoScaling&start=30

But they don't address my scaling problem. I have 3 monitors: a primary (new Lenovo X1 notebook) screen: 1920x1080, and 2 identical, higher resolution external screens (3840x1030). I've posted the output from "screen;" and "various information" below.

I've also tried every combination of "NoAutoScaling" tweak and "Override high dpi scaling behavior", etc. possible, and have spent hours rebooting and refreshing ("fresh;") each configuration, etc. to ensure each one is active. In most cases, the changes don't have any significant impact on the problem. This is especially true for the NoAutoScaling tweak which doesn't seem to affect anything.

So, regardless of the myriad of possible settings, I seem to only have two basic unappealing options:

1. With "Override high dpi scaling" turned off, XYPlorer looks great on my Primary (notebook) (1920x1080) screen but doesn't scale when moved to my external monitors and everything appears tiny (font, menu, icons, etc.). Clear, but tiny. In this scenario I can play with font & toolbar sizes, etc. on the external screens, but of course, everything then appears too large when moved back to my primary screen.

2. With "Override high dpi scaling" turned on (set to "System Enhanced" is best), everything scales properly as I move from screen to screen. However, now the problem is that all text, icons, etc. appears fuzzy when using the primary screen (however, the external screens are clear).

Thoughts? Suggestions? The first option above is the best if only XYPlorer will scale when moved to a higher resolution screen.

I was hoping this might be resolved with the 64bit conversion but that's now off the table. In the last post above, the admin suggested that the problem is "on his list". Any progress - or chance to revisit this problem?

Thanks!!

XYplorer should scale when moved to a higher resolution screen. At least I told it to do so. Are you sure that NoAutoScaling is set to 0?

[ColdNose]

Thanks for the reply.

Yes, confirmed "NoAutoScaling=0". The same situation happens with "fresh;" and I saved a copy of the current config file and verified the NoAutoScaling=0 tweak was set.

Setting it "NoAutoScaling=1" and restarting without saving (and making a copy of the config file to verify!) makes no difference. It still displays perfect on my primary screen, but tiny on my higher resolution screen. So, I don't think the scaling is working either way.

Is there any way to check that scaling was tried?

[admin]

When you run screen; through the address bar, you should see this line in the return if auto-scaling is enabled (generally, and for the toolbar):

Code: Select all

Auto Scaling: Yes, Yes

In the next beta I will add three events to the debug log:

Code: Select all

WM_SETTINGCHANGE (SPI_SETWORKAREA):
WM_DISPLAYCHANGE: 
WM_DPICHANGED: 

After you moved XY to a another monitor you should see either of them in the debug log when you run dlog; through the address bar.

[ColdNose]

Thanks for looking into this.

I've installed the beta 21.30.0005. I then moved XY from my Primary to external monitor and received this with "dlog;" :

Any thoughts? It looks like it is trying to autoscale... but just doesn't scale large enough!

Thanks, once again.

[admin]

Interesting. The screen command shows "Screen DPI: 120 (125%)" on both monitors, which is of course wrong!

This is good. Not sure yet how to fix it but I smell the blood. There will be a solution...

[ColdNose]

If it helps, my scale settings for my secondary monitors is 200%. I've played around with this on each monitor and confirmed that other windows apps (.ie, File Explorer) work as expected: scaling to the setting of each monitor. However, XY's screen; continues to report the screen DPI of the primary monitor ("120 (125%)") for each secondary monitor regardless of its scale setting.

[admin]

With a bit of luck v21.30.0017 might fix the issue. Please try...

[ColdNose]

Unfortunately, no joy. We've gone backwards. The toolbar, tab and breadcrumb lines are now only displaying half height on both the Primary and Secondary screens (see images below). Scaling still doesn't work on the Secondary screens.

Here's the primary screen:

The screen; looks perfect.

But concerning that dlog;, on which monitor did you start up?

[ColdNose]

You should've been a detective! ha!

dlog; indeed reveals the problem. I did 4 tests with each test starting on a different monitor and moving in different pattern among the monitors. See the results below:

Here's what I found:
a) regardless of which monitor I start XY on, dlog always shows that I started on monitor 2 [192, 192];
b) moving between monitors 2->3 or 3->2 (secondary screens) does not register in dlog (the change is not shown);
c) moving from a secondary monitor to the primary monitor (or vice versa) always show correctly.

Interestingly, if I move from primary monitor to a secondary, the tabs and breadcrumbs rows show full height, however the toolbar remains half height. Moving from secondary to primary, the tabs and breadcrumb rows reduce back down to half height. Moves between secondary monitors (2->3, 3->2) do not affect the row heights. This is consistent with changes shown in dlog;.

Test Results and Steps Taken:

Thanks for your report, and sorry to come back so late! I was busy with the same problem. In the meantime I removed much of the code that fruitlessly attempted to auto-scale the app. I'm still investigating the options that remain, but not as my primary activity anymore.

So, I guess with latest betas (v21.30.0037 on) your findings will be outdated, unfortunately. You certainly should not see those half-bars anymore.

[moguiyu]

was waiting for the fix for auto-scaling for years, hope it will finally supported soon.
the latest verison 21.50.0100 still does not auto-scale to different monitor.
