Acer 517-51 laptop Quick Sync disabled with HDMI out connected

[createmedia]

Hello

Acer 17" laptop 517-51 CPU i7-9750H with Intel UHD 630 graphics, RTX2060M 16GB RAM Edius X WG latest.

This is a second hand 2 year old laptop just purchased, (budgets are tight) and is my first laptop with Intel Quick Sync on board.

It has a 2TB NVME M.2 disk for video 2510MB/sec write, 2061MB/sec read according to the BMD Disk Speed test.

Just installed latest Intel GPU drivers from the Intel site and NVidia latest studio driver.

This is weird. Normally on a desktop Intel Quick Sync is enabled by plugging one monitor into the motherboard GPU and the other to the GPU PCIE card.

On a laptop the internal screen I guess represents plugging into the motherboard on a desktop, leaving the RTX2060M to drive the external monitor.

Without the HDMI connected all the tick boxes are available to use hardware decoding and encoding in Edius X system settings and in the exporter.

As soon as any monitor is connected to the HDMI before Edius has loaded the "use hardware" tick boxes become greyed out and stop working, and the tick box disappears in the exporter, however the Intel UHD 630 and the RTX2060 are both still available as an alternate GPU's to choose in system settings.

Now I can fool Intel Quick Sync into working in Edius by connecting the HDMI after Edius X is running, but of course the full screen playback doesn't then know about the second monitor.

The only other observation I have is that there are two choices for the laptop screen refresh rate of 48Hz and 120Hz, the external monitor is 50 or 60Hz, so they are different refresh rates.

So has anyone any ideas how to keep Intel Quick Sync working with the HDMI connected on this laptop, without disconnecting it first?

Or is it a bug?

Performance test note:

Power and NVidia set to maximum performance.

UHD 50p XAVCI it happily edits with a full buffer.

REC window video very jerky on a camera pan with 3840 x 2160 50p project, if the Quick Sync is not working, better looking at the HDMI out from BMD Intensity Shuttle (I have one to try) but that only does 50i and there are some jumps on a pan when playback is first started but then it seems to smooth out, really needs trying with a BMD 50p output device.

HEVC 3840 x 2160 50p BT2020 PQ 10Bit from my iPhone 12 Pro Max it only manages a full buffer at 1/4 resolution but plays a proxy file perfectly fine. Needs PCC adding to correct output gamma.

With the hdmi plugged in do you see the intel graphics still in device manager? If so it should work.
on my laptop I have to right click on the desktop idin and tell it to use the intel graphics to see quick sync.

Yes David UHD 630 is OK in Device Manager and even when Quick Sync isn't available in Edius the Intel UHD 630 is still listed as a GPU to choose in Edius system settings, so that is strange because Edius can still see the embedded GPU at all times, Quick Sync working or not.

The only implication of having the HDMI out connected at Edius start up is it kills Quick Sync in Edius.

I have seen different ways of configuring graphics on laptops and also the way it automaticallu configures itself varying depending on whether on battery or mains, or what is plugged in. You could look at the following:

• Right click on the desktop icon and choose something a bit like "run with graphics processor". I explain a bit more about this here : http://www.dvctraining.co.uk/dvc-pho...ync-on-laptop/ This is quite an old way of doing this and may not be on your laptop any more.
• An alternative is go to the display settings and find "graphics settings" near the bottom. When you open it it should say "desktop app". If EDIUS is not listed click browse and find it. Then click on options and instead of let Windows decide try using one of the other settings and see what happens.
• Your laptop may have its own configuration software running which decides which gpu is given priority in which case you could look for a setting in there.

Thanks very much David.

Option 1 does not exist right click and run with Graphics Processor.

Option 2 has worked for Edius setting open with integrated graphics processor

So all is working now ok? I suspected option 1 would not be there but it was worth a mention. Option 2 is on desktop computers as well.

Yes HEVC UHD from Apple iPhone will now play at half resolution in Edius X on the laptop with Quick Sync and PCC applied, it won't play at all on my Xeon PC (system 4) as no Quick Sync on there.

An i9-12900k PC will play UHD HEVC at 30% CPU at full res.

There is a benefit in Movie Pro app on the iPhone of going for 225% bit rate (50MBits) on HEVC as the detail is better, especially on an HDR UHD TV, but it uses more storage of course.
