[VP16] High DPI scaling: issues..

AVsupport wrote on 8/26/2018, 7:29 PM

My main screen is 4K/50Hz with Win10 scaled at 175%. Everything on the desktop is tack sharp and comfortable icon / text size. Opening VP16 under those circumstances with render a slightly blurry image on icons and text. Same at 150% ('recommended').

Selecting program properties>compatibility> override High DPI scaling by [application] brings this back to usable sharpness, even though this makes the writing is quite a bit smaller than I'd like it to be.. but this seems (for me) the best option.

Other attempts would cause the main screen / preview to size 'a little bit funny'..: I like the preview to be fixed at 1080 which should end up using approx 1/4 of a 4K screen real estate which wasn't the case..

You also have to be careful with windows scaling... I'm not sure if they fixed it yet, but I do know the last time I checked, having your windows scaling above 100% will break external output. The output video gets scaled too, and it displays all strange, doesn't fill the screen, is zoomed in too much, etc.

Yes, but you can override the high DPI behavior and that will fix the external output:

I don't have any issues with my external output..being 1080/50Hz screen, displays all fine. Somehow even 'better' (more stable) than the main display. (both are hanging of the 1060/6GTX)

Ya, it's not a problem for everyone, just specific cases I think. I got Vegas 14 looking great with High DPI on 40" UHD and 32" UHD side by side monitors. Had to do Windows High DPI "application" override to get proper external output to the one UHD display. (Using AMD r9 290).

Thanks for the tip, I was missing my big text on my 4K TV. It only seems to happen on 4K preview monitors.

@AVsupport

Did you try the new Vp16 switch in Options/Preference/Display/'Use High DPI scaling' ?

AVsupport wrote on 8/27/2018, 1:03 AM

@Peter_P thanks for pointing that out (I didn't know that existed): above works OK for font/icon size but sharpness is not optimal @175%. reverted back to application override.

I'm using windows setting of 200% on a main UHD-monitor with 3840x2160 resolution.

AVsupport wrote on 8/27/2018, 1:23 AM

200% results on the main 4K monitor here are even worse with regards to the preview window in 1080 taking up all the screen realestate.

Unfortunately I do not see my toolbar icons of application extensions when changing the .exe property High DPI override and FX controls of for example 'Levels' can not be used.

I see the same, but hovering with the mouse shows that the thumbs are there but the pics on the thumbs are not suited for this High DPI.

Peter_P wrote on 8/27/2018, 4:58 AM

Yes, this is the same, you can see in my screen shot, with 'Show Recording Data'. But much worse is, that you can not use the controls of the FX to set the parameter.

AVsupport wrote on 8/27/2018, 6:10 AM

.. guys, make sure you check how much relative size your preview window takes up with your sizing methods (and whether that stacks up..)

I have the same issue

There are ongoing issues with this in VP16 build 307. There's some discussion between @Peter_P & @bitman on the general thread starting here. Please use this thread for ongoing discussion.

AVsupport wrote on 10/28/2018, 4:18 PM

still using 'application override' for 307 (which still works fine as a workaround) until I have a moment to try the 'experimental high DPI' vegas button..

Peter_P wrote on 10/29/2018, 1:53 AM

Unfortunately this don't work for me either. I get the same problems with the FX interfaces and the icons.

Had a quick re-check of the latest release VP16.361:

Old issues seem pretty much the same. I don't think there's been any particular coding love in this area. Essentially, I'm using a 4K main screen (@ 175% scaling) and a FHD 1080 100% as an external preview monitor. The performance for the main screen seems 'undercooked' when running Preview(Full), as if there's not enough system resources allocated for a full 1080 screen 'inside' a 4K display. This may have to do with the [menu options]>[preview device] would have been set to 1080? My external screen always looks nicer somehow, less tearing, less apparent frame drops etc. Can't really use application controlled scaling as this will result in an external preview that sits in the lower left corner of the external screen.. Work in progress it seems..

This would be quite awesome if it worked well, because it could be on of those things that Vegas has over Resolve, which requires extra hardware for an external preview monitor. Having said that, Preview robustness and quality of a FHD 'program screen' on a 4K main screen there is a fair bit better... (sorry @NickHope this issue isn't seemingly being addressed over the versions and the other linked thread is rather version specific..)

Maybe one step forward would be to be able to better address main screen attributes and 'External Preview Options' if there's more than one screen realestate..

The devil is in running such high screen resolution. Windows raster scaling was never designed to overcome this.

You don't need 4k screen resolution to accurately preview 4k source. The preview image won't look any different at 1080, but your eyes will be less stressed out by all the other stuff.

I have bad eyes. Nothing above 125% ever works the way I want, not in browsers, windows, or applications, Vegas being no worse than many.

AVsupport wrote on 1/25/2019, 10:17 PM

My main screen in 175% is sharp AS (the way I run it). Promise. I hate soft stuff it drives me mad. I don't think windows struggles, otherwise Davinci would look crap also, and it doesn't. (-> having said that, it doesn't like the external being 1080 'only' hence everything is waaay too big on the external screen and thus unusable..) Happy Australia Day for those who care ;-)

Do let us know how it resolves for you.

By "this thread" I meant THIS thread, not that thread. Sorry for the ambibuity. My comment was just to link to some parallel discussion, and to encourage use of this thread for further discussion.

I run my high res laptop screen at 1920x1280 with the DPI @ 175%. On some plug-ins and render windows, I must re-adjust the DPI to 150% or (the recommended) 125% at access the lower part of the window. Unfortunately, the settings and text are barely legible. This is not an issue w/ VP-9

You don't need 4k screen resolution to accurately preview 4k source. The preview image won't look any different at 1080, [..]

I bought a 4K main screen for the following reasons:

If i shot in 4K, and deliver in 4K, I could use the main screen to check on the footage (pixel for pixel).
If I edit for 1080, whatever the source material, the main screen would give me enough realestate to allow for a 'full-frame 1920x1080 pixel for pixel' preview, without the need for recompression etc; I was expecting the program to perform better (less load), with better results in the main preview (better quality).

One will probably not see my issues on a -say 1920x1280 main screen whereas 4K is 4x the data...old story
