Office Hours: May 12, 2022
Mixing Light Contributor Cullen Kelly joins host Patrick Inhofer in leading a discussion with Flander’s Scientific’s CEO, Bram Desmet. The topic of the day: Professional reference displays.
Today, the questions we answered included:
- Does 4k or 8k mastering make a difference for color grading?
- Can you use an old i1Display colorimeter for calibration?
- What are the differences between FSI’s different model lines?
- Can you use single-zone backlight displays for HDR monitoring?
- What is ‘volumetric collapse’ and how does that relate to OLEDs?
- Does it make sense to integrate a top-emission OLED into a grading theater for checking theatrical deliverables?
- And much more…

00:00 – Introductions
01:52 – Patrick asks Bram about the progression of LCD displays over the past 15 years.
03:14 – Bram recounts the cyclical trend of leading display technologies being abandoned before equivalent replacements are available.
04:55 – How FSI uses a mix of display technologies to meet the varied needs of professional users and how the tech has changed over time.
08:06 – How pro display manufacturers are ‘piggy-backing’ off the consumer display market
10:25 – How FSI recently decided to start manufacturing their own backlights since they couldn’t find another commercial solution that allowed them to produce 5,000 nit displays
12:32 – Why Bram thinks its important for FSI to push displays past the 1,000nit threshold
13:18 – How does FSI guide potential customers about the value and performance of lower priced displays?
14:33 – Bram talks about lower priced ‘HDR’ displays and what they’re ‘good enough’ for and where they have flaws
15:42 – They types of HDR displays that FSI won’t produce or market
16:31 – What does it mean if someone says a display has ‘volumetric issues’
20:43 – What are the proper display benchmarks you should evaluate when considering purchasing for HDR mastering?
25:00 – How do we get Resolve to send the HDR flag to consumer displays while we’re grading?
27:00 – Does resolution matter in the grading suite? Specifically 8K vs 4K?
32:49 – Should I swap out my smaller 23″ reference display for a large format 55″ or 65″ display and run with only a single monitor?
34:04 – Bram talks about FSI’s upcoming new 55″ and 65″ displays
36:14 – What does it mean when someone says a display has ‘better stability’? What’s ‘stability’?
37:37 – What’s the life expectancy of the newer models that are being released?
39:32 – If you feed black into your display and leave it turned on, do those hours count towards the lifespan of the display?
41:13 – What about a non-OLED display, the BM170, what’s its life expectancy?
42:13 – Can I use a 6-year-old i1Display colorimeter for calibrating an FSI display using Autocal?
51:18 – What’s the naming mean across the various difference series of FSI displays (BM-series, DM-series, XM-series, etc)?
53:18 – If I own an FSI display and have an i1Display colorimeter then is there an advantage to ship the colorimeter to FSI along with the reference display?
54:51 – Does getting the i1Display colorimeter re-calibrated by FSI every year, and using it with Autocal, replace the need for annually sending in the actual display?
56:43 – A Mixing Light member talks about his 10-year-old FSI display.
57:41 – Is ‘volumetric collapse’ a problem with specific models of OLEDs?
59:53 – Does FSI plan on releasing a 24″ HDR at 1,000nits for under $10k?
1:00:43 – Bram talks about single backlight, non-zoned HDR displays
1:01:28 – Bram talks about full array local dimming (FALD) backlight displays for HDR monitoring – and when it makes sense to pay the premium for those displays
1:05:12 – Upcoming trade shows where you can find FSI
1:05:56 – Does it make sense to integrate a top emission OLED into a color grading theater with a projector? Advantages or drawbacks?
1:09:32 – How do you know if you colorimeter has drifted and how do you know if the device re-calibrating the colorimeter has drifted, itself?!? A conversation ensues…
1:17:07 – Bram invites members to reach out to him with questions.
