New work laptop.. .I'm screwed aren't I?

ensete basically use a 'safe' Windows PC, then use a capture card to output the 'Windows 11 PC" to that card.. Use VLC to view it on the 'safe' PC. Seems fairly usable. I don't think the capture card really matters, I just got a cheap one from Amazon.

markdotpeters5 When I said specific I mean specific hardware with links to that specific hardware. There are approximately eleventy bajillion USB capture cards on the market.

ensete I really don't think it's the model that made the difference, but here's the link NEWHOPE video capture card, 4K HDMI to USB C 3.0 capture card, 1080P HD 60fps Live and Record Video Audio Grabber for Gaming, Streaming, Teaching, Video Conference: Amazon.co.uk: Computers & Accessories

If I would disregard all the noise out there, including this forum, I would naturally gravitate towards asus zenbook, vivobook laptops with IPS flicker free certified displays, also would discover MSI and gigabyte laptops, they also ship their machines with flicker free certification. The later is used by Elon Musk too as far as I have read online. And of course we all discussed this issue of flicker free means no low frequency flicker, but anything more than that should be checked with pro tools.

Donux having personally tried many displays that are 'flicker free' which are anything but, I'll pass. There are some very experienced and clever people on this forum, from which I've learned a great deal.

You don't need 'pro tools' to check flicker, you just need an Opple Lightmaster which are readily available for under £100/$100

markdotpeters5 Well good luck with $100 Lightmaster 🙂 From my side, all I am saying is - its better to have manufacturer to write its flicker free, rather than not to write. Screens might be bad, but not extremely bad, and there is a sign of some level of awareness that customers care about it. Its a positive thing.

That's where I have some discontent. I don't have an Opple however my understanding is the specifications are ambiguous about it's exact measurement capabilities (e.g no explicit frequency response) and some of the graphs/readouts look suspicious to me.

I wonder how can you file ADA is this condition is not a disability that is acknowledged?

markdotpeters5

JTL suspicious based on? There are a few peculiarities around how it measures, for example the numbers on dc-like dimming are sometimes confusing, but it's very accurate. If you can find a better/more accurate tool for the price, please let me know!

The U.S. Department of Energy actually evaluated handheld consumer flicker devices and smartphone apps and compared them with professional devices. They have a few studies here: https://www.energy.gov/eere/ssl/articles/characterizing-photometric-flicker?nrg_redirect=429873

The conclusion was they were much more accurate than expected in a lot of situations. Of course not as exacting as professional ones, as you said, but they seemed capable of confirming a source was problematic.

I’ve noticed most people testing using Opple are doing so in stores with intense lighting. You’re not going to get an accurate reading under those circumstances.

But in a pitch black room measuring only the device? I think it would be fairly useful.

Understanding of (some) EE theory and experience with oscilloscope measurements.

I think the quirks you described and also the fact that (as far as I'm aware) it doesn't have an explicit frequency response speaks for some of itself. Also, as I understand, it cannot measure flicker that isn't a single absolute variation as a single frequency.

If you can find a better/more accurate tool for the price, please let me know!

Don't know about "the price" and I've never used one but at least some of the UPRTek meters are rated as measuring up to 100Khz in the specifications, so that's somewhat better, but the latter caveat of being unable to measure frequency components may still apply.

I skimmed over it and didn't see the Opple there? My particular criticism is of the Opple, but some of the other issues could apply to other devices as well.

markdotpeters5

AshX I think that's fairly common knowledge. Certainly all of the people I speak to regularly that have one know to completely omit other artificial light sources. Anyway, this is digressing away from the topic of this thread..
