Pixinsight 1.8.5 High-dpi support for Win 10
« on: 2017 August 03 22:34:29 »
After installing the new versión 1.8.5 I noticed that it is not supporting high resolution display in Windows.
In my 13-inches high resolution display there is no way I can use this versión.
Where can I get the previous version 1.8.4? I do not see it in the download section.
I need to go back to that versión so I can use PI in my notebook.

Thanks,
Renan

Hi Renan,

Of course version 1.8.5 does support high-dpi displays on all platforms. However, your 13" laptop probably does not meet the minimum screen resolution requirements. Anyway, you can run PixInsight on it, but you'll have to change a Preferences setting. If you tell us what is the resolution of your display, we'll be able to help you with this. A screen shot of PixInsight running on your laptop also would help.

Attached a screen capture regarding PI High-DPI info that it is shown by putting the mouse over the option.
My screen resolution is 3200 x 1800
I tried both, Maximize at startup and Full screen at start up.
As I said begore, ver 1,8,4 was working fine.
Thanhs,
Renan

This preferences option has nothing to do with high-dpi user interface representations. It refers exclusively to image (that is, pixel data) screen renditions.

On macOS with Retina displays, software applications have the option to work either in logical or physical pixels to represent images. A logical pixel comprises four physical pixels on macOS at all Retina resolutions, so the operating system applies an effective 2x magnification factor to the screen coordinate system on all Retina displays. By default, PixInsight represents images using physical pixels on macOS/Retina. This requires generation of 4x the amount of screen data normally rendered at standard resolutions. This preferences option allows you to select logical pixels representations, which are 4x faster but don't make use of native Retina resolutions.

On Linux and Windows, the operating system does not perform automatic screen scaling like macOS. This means that applications always have to work directly with physical pixels on these platforms, and hence the preferences option in question does not make sense.

So yes, PixInsight will *always* use the native screen resolution of your monitor. The screenshot you've posted looks perfectly normal. Why are you saying that PixInsight does not work on your laptop?

If the problem is that you have very little working space, you can fine tune the font dpi setting in Preferences. This works exactly the same way as in version 1.8.4. Bear in mind that irrespective of the native high resolution of your display, the logical display resolution is very low: 1600x900 pixels, probably. The logical resolution is relevant for representation on UI elements (text, buttons, menus, etc.), while the physical resolution is exclusively used to render image data. Without more information, more descriptions or some screenshots, I can't help you better.

The screen capture was from my PC, not my notebook since the only poorpuse was to show that info.

From my notebook is almost unreadable.

I will adjust the font settings and let you know,

Thanks,
Renan
