Post subject:  Scaling with UHD (4K)
Hello Henry,

I got a 4K display now and I have quite some issues with the client.

If I run it on the unmodified Windows 7 (scaling by 100%), SL runs in the correct resolution and all, but all the windows UI is way too smal and unreadable.
If I use those 150% or custom scaling settings to scale up the Windows UI, SL itself scales up too. Means:
- desktop itself is 4K, but
- maximized client window only has a reduced resolution (2560x1379 pixels) and everything is blurry because all pixels get multiplied.
- fullscreen client displays the upper left quarter of the client in the full, other 3/4 vanish at the bottom and right.

Any idea how to avoid that scaling in the SL window/fullscreen?

Same happens with other SL clients, too.

World of Warcraft for example runs with the full resolution at least in fullscreen.

I don't have a 4K monitor... I'm still with a 1680x1050 monitor, here... Plus, I use Linux, not Mickey Mouse's OS Windoze... :mrgreen:
So, it's hard for me to find a solution for your particular system...

My advices however are:
  • Verify that the graphics driver is setup to display at the screen native resolution (GPUs allow to scale the picture on the fly, but it will get blurry since unlike an old CRT monitor that could "interpolate" via the native averaging of the light on the photophores when the cathodic beam was shooting between them, the modern LCD (or plasma) screens can't average at the screen level and can only properly display at their native resolution or half, or any sub-multiple of 2).
  • Verify that your monitor itself is not set to scale the display but will only center smaller resolutions (this will also help you spotting an issue at the OS/driver level): scaling at the monitor level got the same effect as via the GPU, i.e. a blurry image !
  • Always favour the windowed mode for the viewer (this will ensure that it will not try to use a resolution that is not your screen's native one): with a 4K display, the window title and borders should really not make any difference once maximized anyway (and you can set the Windows task bar to auto-hide, so that the window can take the full screen space).
  • Oh... and also verify that your graphics card (and driver) can *actually* do 4K in OpenGL... 2560x1380 sounds like a GPU/driver limit...

I switched back to 100% scaling = no scaling of fonts/icons and stuff and instead got into the settings where you can change fonts, font sizes, bar sizes, sliders etc. and enlarged them there.

With this the client too behaves well. I have some small icons or VERY small fonts here and there on windows and apps, but I can live with that.

I'll watch what M$ is going to do about 4K in the future, I read that some details got improved in Win 8.1 already. But I probably skip 8.x completely and go for 9.x instead.

But you could re-add 4K/UHD to the fullscreen resolution list again? You once added that one and the 27" MAC resolution (2560x1440) too, but they seem to be gone for quite some time again. But now 4K displays are at a pricetag around $600/€600, so more people will get them.

Oh, and I could need a UI scale to 2.0, 1.5 is really too small right now. :D I mean, look at the small menus in the snapshot. :D http://tillie-world.net/files/CoolVLViewer-2014-06-12-18-51-45-89.jpg Load this, zoom out so it fits your screen and then look at the menus. :p

If you ever need some testing with 4K resolution in the future, just tell me. I might set up a virtual box with linux too, and test there if needed. If that works at all. :)

They never were available in the Cool VL Viewer graphics settings... You must be confusing it with another viewer. I'll add them, but you could as well do it yourself (it's just a matter of editing the panel_preferences_graphics1.xml file).

I won't call it cheap, by far !... I bought my 22" 1680x1050 LCD monitor for 200€, and that was 4 years ago (it was not the widest screen back then, but only "HD" screens did better, so that price was for the upper mid-range monitors).

Well, to have a practical use of a monitor for anything else than watching ultra-high definition videos (i.e. if you want to actually read text on them), you need it to sports 120dpi maximum, and will get a much more readable display at 96dpi... For a UHD-1 (3840×2160 pixels) monitor, this means a diagonal of sqrt(3840^2+2160^2)/120=36.7" and sqrt(3840^2+2160^2)/96=45.9" much preferred... AFAIK, the largest UHD monitors only sport a 32" diagonal (138dpi: way too much !) and that's why 4K monitors are overrated/useless, as far as I am concerned...

Not true, they were in some time ago, see your own forum: viewtopic.php?f=5&t=813&p=3637

Yah, I edited it in already, but I need to patch that file every week with your updates coming in. :-)

Are you calling me a liar ?... Please, verify your "facts" before stating them. Here are the real FACTS: the patch for the release were you pretend the UHD resolutions were added is available here, and the lines in that patch corresponding to the added resolutions are:

As you can see by yourself, I didn't add the UHD resolution back then (just because there were no (non-professional) UHD monitors with such high a resolution at that time: it was 2 years ago), and never did so far.

Btw. I found out how to have the desktop UI scaled up without all app window contents being scaled up too...

- You set the scale factor, eg. 200% ... this will double all UI elements to double size, and scale all stuff like SL window content, too.
- Now you rightclick the icon of the app that you dont want to scale, like the SL client, choose
* Properties
* Compatibility tab
* check "Disable display scaling on high DPI settings"
* click OK

Now my Windows desktop looks like before (except some few blurrier icons that had no higher res version available, TheBat! funnily instead of a stamp with a bat on it has a new icon now with a donkey wearing a blue postal cap, easter egg? :D ) and apps like the SL clients still have high resolution inside. :-)

And with the new Adobe CC update even stuff like Photoshop is usable with 4K displays again. Wasn't before, cause their UI doesn't scale with the windows settings (they totally did NOT use the Windows APIs apparently, lots of ranting in the adobe forums about this).

So UHD is usable, even without having Windows 8.1 (which has some additional stuff for HighDPI displays or if you connect several displays that have different resolution), Win 7 is good. So I can live with it until Windows 9. :P

If I run the viewer in Fullscreen Mode on my 1080P monitor and chnage the viewer size to 1080P the fonts and UI. are huge which is a great thing for me as it's easy to read. I assume you can do the same thing with the 4K monitor? In Windowed mode I only manage 1920x1061. The only issue I have with Fullscreen mode is since I run 2 monitors and I shift focus to the 2nd monitor the viewer on the first monitor minimizes. I've searched for a workaround as yet ot founf one successful.

Hello Henri,

just a quick Thank you! for extending the UI scaling range even though you're unconvinced by high resolution displays. Having just joined the ranks of the '4K' owners, 1.75 provides me with a nicely usable viewer again.

Love,
Lia
