HP and Dell disable HEVC support built into their laptops' CPUs

wongarsu

> For example, no background blurring in conference programs, significantly degraded system performance

So HP and Dell, two companies well knows for business laptops, sell some laptops with degraded video conferencing, all to save $0.24 per laptop? And Dell doesn't even mention this in the spec sheet or give you a straight list which models are affected?

I can't help but think that the reputational damage from "my new Dell laptop sucks with Teams, the previous one with worse specs was fine" is going to be a lot more expensive long-term than those $0.24

malfist

Note that it's not a $0.24 increase Dell and HP are upset over, its an increase of $0.04. The price they were paying was $0.20.

So if you have a Dell or HP laptop, you're hardware acceleration is because your experience with the hardware isn't worth $0.04 to the OEM.

I can't say I understand why HEVC support being disabled would "prevent background blurring", especially because 1) the blur has nothing to do with HW decode (not even in weird unknown parts of the MPEG-4 specs like video object planes in part 2, or better yet: part 6 and part 16) — and 2), AVC HW encode is still there and is a completely acceptable fallback, so...?

tomasphan

It doesn’t. Disabling hardware acceleration does which they needed to do in order to play content.

“ needed to either have the HEVC codec from the Microsoft Store removed entirely from [Microsoft Media Foundation] or have hardware acceleration disabled in their web browser/web app, which causes a number of other problems / feature [degradations]. For example, no background blurring in conference programs”

Sesse__

The blur happens on the GPU. HEVC encode also happens on the GPU (or at least a GPU-adjacent device; it's rarely a full-shader affair). If you were to use HEVC software encode with GPU blur, you'd need to send the camera data to the GPU, pull it back to the CPU, and then software encode. Performant GPU readback is often cumbersome enough that developers won't bother.

It probably switches video processing to some legacy stack, that doesn't have all the features.

hosteur

Hmm.. I guess if this explains why my new work Dell Latitude becomes extremely laggy and unstable when doing Teams meetings with multiple video streams. My 5+ year older Dell Latitude did not have this problem.

andix

Isn't there a certification for ms teams for pcs? I've seen a lot of headsets and speakers with a "certified for ms teams" badge on it. I guess Microsoft needs to extend it to laptops too, make hevc support mandatory and tell their customers.

graemep

The fear may also be that if they pay this there will be further increases in the price. its going up 20% in a few months. What if they think it will double next time, and then in another year etc?

iso1631

That will be someone elses area

Boss 1 saved 0.02% of the cost of the laptop, but thanks to scale works out to be $2.4m. He walks away with his $240k bonus.

Boss 2 sees increased complaints about Teams and blames Microsoft.

miki123211

Nope, boss2 fixes those complaints and gets the relevant complaint rate down by 300%. Everybody conveniently forgets why it was so high in the first place.

snvzz

Does MS Teams actually use HEVC rather than VP9 or AV1?

If so, time for customers to complain to Microsoft.

mort96

And does the background blurring part of their pipeline somehow consume the raw H.265 bitstream directly..? Wouldn't they be blurring based on the raw pixel buffer, before any encoding takes place?

ksec

The problem is double dipping. If Intel and AMD represent 100% of all x86 Laptop. In theory Intel and AMD would pay the HEVC fees once, which is capped IRRC at $100M from all patent pool together. And all x86 devices would have HEVC licenses. HP and Dell shouldn't have to pay for it.

In practice it seems everyone in the value chain are forced to pay, Intel, AMD, Nvidia, HP, Dell and then even browser and software.

Luckily H.264 High Profile is already patent free in many countries and soon to be patent free in US too. Let's hope AV2 really get its act together this time around. Then the world would just be H.264 as baseline and AV2 for high quality.

> In theory Intel and AMD would pay the HEVC fees once, which is capped IRRC at $100M from all patent pool together.

My understanding is that the licensing lawyers learned from Cisco doing that with H.264 for Firefox and there isn’t a cap with H.265.

F3nd0

Until AV3 finally rolls around, of course. Then the world would be just H.264 as baseline and AV3 for high quality.

egorfine

Isn't it something that was already sold to me as a customer? I don't get it how company could remove one of the features that has been already sold to me.

Edit: I was wrong, I misread “purchase” as “purchased” which aligned with my (flawed) memory of what happened and it made sense with the full sentence. Original comment remains below.

It’s not without precedent.

egorfine

The example you provided is exactly the opposite:

> no longer be available on newly purchased Apple Watch ... > customers who purchase the watches in the U.S. will still be able to see Apple's Blood Oxygen app

latexr

Edit: I misread “purchase” as “purchased”, which is wrong.

You’re removing the important part. Here’s the full sentence, with emphasis:

> According to the tech giant, customers who purchase the watches in the U.S. will still be able to see Apple's Blood Oxygen app on their devices, but when tapped, users will get a message saying the feature is no longer available.

In other words, you saw the icon for the app but it didn’t work. The feature had been removed even for those who had already paid for it.

The article is a bit light on technical details. Can someone shed a light on how hardware decoding is disabled? Do they blow an efuse, disable it in the firmware or in the OS?

Yokolos

It's not disabled in the sense many people are thinking. The codecs just aren't installed by default. The hardware is present and still functional. You just have to use software that directly supports HEVC or buy your own HEVC license on the Microsoft store for $1 to get system-wide hardware accelerated HEVC codecs.

TiredOfLife

The hardware acceleration is disabled in driver. Even using VLC you won't have acceleration for HEVC.

snvzz

Even on Linux?

kotaKat

From what I'd heard, it's the actual HP and Dell OEM'ed drivers they provide for the hardware. If you load the official Intel drivers, HEVC works fine.

It's also reported that HEVC works fine on Linux on these affected laptops.

dist-epoch

Just like the embedded GPU in a CPU needs a driver to work, the embedded video decoder/encoder also needs a driver.

zajio1am

How much relevant is HEVC on computers? I encounter H.264, VP9 and AV1 and that is pretty much all. I know HEVC is used on Blu-ray and in DVB-T, but that is usually played by dedicated hardware, not PC.

fleshmonad

I don't know about you, but I have a large selection of 10 bit HEVC movies and series on my system, and hardware decoding for this is pretty nice. Apart from that, videos taken on apple devices use HEVC by default last time I checked. But in the end, it's still not that important probably, doesn't mean that it shouldn't be available/accessible

tkel

For recording video on phones, there is h.264, and the relatively newer, better option HEVC.

Thus much of peoples' photo library is becoming HEVC.

andix

Is it possible to just buy the HEVC extension on the Microsoft store to enable it?

I have a PC that came without the license, and I had to buy it to get everything working. It was more an annoyance than a problem, it's only a 99 cent purchase.

Sam6late

It is likely linked to increased HEVC licensing costs starting January 2026. The increased HEVC licensing costs starting January 2026 are due to a 25% rate adjustment announced by Access Advance LLC, which manages the HEVC Advance patent pool. https://accessadvance.com/2025/07/21/access-advance-announce...

Numerlor

Yes it should work with the codec pack, and they're keeping it on some of their laptops like with dedicated gpus

andix

So the fault is at purchasing departments, that buy incompatible laptops. They would probably need to order hevc as an option, or roll out licenses via MDM.

Individual buyers can just buy the HEVC license from the Windows store. I think windows even opens the store, if the codec is missing. A lot of companies disable the public App Store on their MDM though.

If missing licenses impact end users on a larger scale, it's also a communication issue from the manufacturers. This won't do them any good, as customers will be annoyed from the bad user experience. Even if one in 100 customers switches the brand, they make a loss.

marcodiego

AFAIK, using linux instead if windows fixes the problem.

conartist6

Force them all into 480p video and link them back to the information that the mfg crippled them to save a few cents.

bayindirh

While an individual license is 25¢ [0], $25MM is a somewhat sizeable amount of money for any company.

However, I'd personally accept to be able to buy my own license and enable the hardware a-la Raspberry Pi fashion.

Moreover, this is done on more expensive, business notebooks as well, which are both more expensive and used by the people who knows about this stuff.

The executives who made these decisions are not the most informed or the most brilliant, I assume.

ZeroGravitas

For the first device mentioned it has a discrete Nvidia GPU which also supports HEVC encode/decode in hardware, which I assume is also disabled?

BLKNSLVR

I'm assuming it's being disabled in firmware. Is there a way to re-enable it? Can the firmware be downgraded?

xnx

Would be more acceptable if it was possible to pay $0.24 to enable it.

dtech

You can, you need to buy a codec from the Microsoft store for $1 or local equivalent. Most people won't know this.

xnx

Does the codec enable the hardware support?

dist-epoch

Not even that, you just need to know the "hidden" link to the codecs, then it's free. I'm sure Microsoft is well aware of these links, there are many articles about them.

bayindirh

Having the feature > being able to buy it > being completely locked out of > have to subscribe to a recurring payment.

HPsquared

It's like those cars where you pay a subscription to use the heated seats.
