The UI DPI Settings Change Screen

This is what fixes the problem for me until it happens randomly later

I also run Windows 10, x64, and run a UHD 2560P60Hz display through HDMI 2.0 in TV colour space YcBrCr420, the default recommended DPI is 300% by Microsoft for my setup and I run that

A long time ago both in betas and prod releases I reported that on initial playback the video display would be very small and not instantly fill the whole screen. The bug reports were not actioned by Cyberlink and unfortunately thats not an isolated case theyve ignored some very serious defects in their software

Your symptoms are similar but a little different to mine mate - for my setup PDVD will eventually fill the whole fullscreen area its just limited to initial playback. Also, there is no difference to this behavior on different container formats, different video codecs, different resolutions etcetc all videos are the same.

Just an update: CyberLink Support Team has notified me they have Escalated this to the R&D Team and they will provide an answer as soon as they have one. These things can be confounding at a system level to sort out with all manner of hardware and O/S combinations. I trust they will follow through. See their reply attached.

At least this is not a serious error and I do have a simple work-around to rely on until it does get patched up.

I have the exact same issue. I assume no fix has been released yet? It occurs with ALL file types, specially with mp4

Tech Support tried to help with this but later advised they were not able to duplicate the problem. Given the number of people commenting on this, all over the web; I would say this is not an isolated issue at all and should be fairly easy for anyone to duplicate.

That said, we have to remember this relatively small company with limited resources (based in Taiwan) is trying to satisfy a world market in multiple languages, numerous O/S platforms & configurations. World-wide there are major differences in electrical currents & frequencies and how hardware handles those issues. There are also a multitude of display devices. No doubt, some of that results in what we are experiencing. Without the resources of a giant company behind them, they will never be able to solve all our problems despite their best efforts to keep all of us happy.

As far as the UI / DPI settings goes; this internal PDVD bug isn't actually altering the UI / DPI settings within Windows. Rather, PDVD is changing it's own internal interpretation of how to react to the Windows DPI settings it sees. Due to some random bug it just goes off on the wrong tangent in and of it's own accord but it changes nothing within Windows itself.

If there were a user specified setting within PDVD where we could simply force the software to maintain whatever DPI interpretation we needed for our display device - this would not be an issue at all. Perhaps CyberLink would do this if more of us suggested it? This would be a simple, easy and reliable fix. Any coder at CyberLink could easily include such an option on the settings menu and the program could be forced to use that rather than make it's own intermittantly incorrect choices.

As more and more people start using UHD / 4K TV's as display devices I think this need will become evident. I don't think CyberLink realizes how failure to correct this problem will affect future sales and reputation of its products. It will eventually have a huge impact to them. They really need to resolve the issue sooner than later.

I suggest that those of us experiencing this problem should contact CyberLink with a request to include a user specified option on the settings menu and force their software to use that. They could still maintain the "automatic" method that currently works on most standard PC-Monitor configurations. This would be a quick and easy fix for their software coding team. Perhaps it hasn't fully soaked in that they really need to do this?

Sometimes the obvious solution is staring us in the face but we can't see the forest for the trees. I think this is the case with CyberLink on this issue.

If I were their Corporate Controller, CFO, or VP of Finance, I'd be watching the rise in UHD / 4K display devices being put into use as a computer display and correlate the lack of action will render the product worthless to a large and quickly growing customer base. I'd sure be taking note and directing the development team to get on it immediately.

The fix is very quick and simple from a coding standpoint. Just give us the option on the settings menu to force the settings we require for our hardware configuration. Failure to act will eventually plummet future sales and potentially overwhelm tech support / customer service. Regardless, it will eventually come to them that action is needed.

Just for the record, I have this issue too, and have done ever since I upgraded to a 4k TV around September of 2015. I never noticed the issue on my previous 1080p set.

My HPTC
Running PowerDVD15
Win 8.1 x64
Initially I had a GTX660
Upgraded to GTX960 for HEVC decoding and HDMI 2
i5 quad core 3.5ghz.

I got my first UHD HEVC file yesterday, and this takes quite a while before it goes to full screen, and is also the reason I came to the forum today, to start a new thread about HEVC acceleration not working.

Before the image fills the screen the program seems unresponsive, and the info at the bottom of the screen, such as time passed and time remaining is not available. As soon as the image jumps to full screen, everythhing is normal.
I've also noticed it seems to take longer to fill the screen when first launching the program, compared to then quitting and launching again.
IE. I just loaded a 720p mkv file. It took seven seconds of having the image only in the top, left hand side quarter of the screen, before it filled the screen.
I quit, reloaded and it then took 1-1.5 seconds.

I had assumed it was something to do with the graphic card. I also noticed just now, that after the seven seconds were up, the very moment the video jumped to full screen, the hard drive seemed to access a lot for a few seconds.
I have an SSD boot drive and only have media on the mechanical drive. Maybe this is irrelevant, but I wanted to mention it.
It never annoyed me enough to complain, but after spotting this thread I thought I'd mention that it happens to another customer too.



EDIT: I think I have my scaling set at around 200%.

Hello there,

Same issue here. I use a new Alienware 17 laptop - with max. out hardware... Also a 4K UHD display.

I have an internal onboard graphics card from Intel (used as standard display driver = browsers / windows ui / videos / pictures) and a Geforce 980M used for gaming and powerdirector.

Randomly when I want to watch videos with powerdvd ultra 15 it doesn't open them correctly... the video gets playbacked in the left corner of the screen and the powerdvd ui becomes unresponsive until it crashes... there is no way to watch a video when it does this... i just have to restart the video a few times or just use any other player like VLC / Windows Media Player... ONLY THE EXPENSIVE POWERDVD ULTRA 15 HAS THIS ISSUES!

It seems that PowerDvd is not ready yet for 4K displays and graphic card drivers.... found many people with similar problems but no solution or info by cyberlink!

As I said, I reported this problem to CYberlink ages ago. When the tech support mob say they forwarded it to the Dev Team, dont hold your breath. It doesnt mean they will fix it. Im still waiting since PDVD version 10 for deinterlacing to work. And I'm still waiting for subtitles in high DPI situations in 4K to be fixed. If they fix anything at all, be prepared to wait months minimum for it. They may never fix it however.

Same Situation with the new PDVD 16?
