Thanks to those who attended the webinar! If you did not have a chance to listen live, the video has been posted here. Check it out!
We had a lot of great questions during the session and I wanted to share some that I thought would benefit everyone. Feel free to comment below and share some of the things that you are seeing out there!
Thanks again and I'll see ya on the next one!
Q. In regards to the output of the Six G generator...8bit or 10bit?
A. My general practice is to try to mimic the source as closely as possible. That being said, I have tried window patterns at both 8 bit and 10bit and have not noticed any variances in the measurements.
Q. In regards to the screenshot showing the Six A analyzer showing a 17.82Gbps signal coming out of the player..."if that is almost 18Gbps then what would 4:4:4 with 10bit look like?
A. 4k 60 4:4:4 10bit exceeds 18Gbps and is beyond the system's capability. You would either have to drop the frame rate, color subsampling, or keep it at 8bit. This calculator is a super helpful tool that will help you calculate bandwidth.
Q. Does the Six A/Six G combo test cable bandwidth?
A. Yes! So does the Fox and Hound kit
Q. Why is UHD, etc in the TV not turned on by default? Will that be a problem with older 1080p devices?
A. If the TV has no picture or a flashing picture right out of the box, the customer will most likely return the TV. A safe EDID that works with virtually everything simply eliminates returns. The customer brings the TV home, unboxes it, plugs everything in, and gets a picture. Unfortunately if you do configure the inputs on the TV, the TV will never ask the source for HDR. This is why it is so essential to set up the TV and each component correctly.
Q. When profiling the K10 to the i1Pro2, which window size do you recommend?
A. I have had the most luck and consistency when using 10% windows. Don’t forget to use the Full Frame Pattern Insertion so the patterns to not drop in luminance while you are trying to calibrate. The default settings for FFPI are fine for OLED.
Q. I have the Murideo Six G with FW 1.87 and yours says 2.60. Is there new FW for the 1.x version?
A. 1.87 is the most up to date version for your Six G. There are 2.x versions out there, but the only difference is some internal hardware. There is no difference otherwise.
Q. For 2pt grayscale, which patterns do you use?
A. When calibrating SDR or HDR, I tend to use 80 and 30 as my two points (80 first). After calibrating 80 and 30 I like to take a full sweep of the grayscale and check it for linearity. If the grayscale is linear, I move on to the 10pt or 20pt (if the TV has it) and start touching up individual levels. If the grayscale is still messy after using the 2pt with 80 and 30, I might try calibrating 70 and 40 instead. It all depends on where in the grayscale the errors are and how bad they are. I remember one TV years ago that gave me the best results after calibrating 90 and 10. In all actuality 80 and 30 work best for me most of the time.
Q. Does the SC1 manage HDCP if the sink is not 2.2 compliant?
A. Yes! The SC1 can support HDCP 1.4 as well.
Q. In regards to setting up gamma for SDR...always use BT.1886 or no?
A. Yes If you are in a dedicated theater room or a room with 100% light control. Also take into consideration how far away the viewer is from the screen. BT.1886 is almost identical to the 2.4 curve so I only use it in ideal rooms with ideal viewing situations. You may still consider using 2.2 if the room has ANY ambient light or if the viewer is sitting further away from the display than normal.
Q. Does SDR calibration effect HDR on Sony TVs?
A. Yes! This is exactly why I have been calibrating 2 different modes and color temperatures on Sony TVs. For example, I might use Cinema Pro/Expert 1 for SDR and Cinema Home/Expert 2 for HDR. I found that if you use the same grayscale settings from SDR to HDR they do not match each other.
Q. How do you calibrate the TVs internal apps if you cannot see test patterns?
A. Excellent question! I fought with this a lot when I personally started primarily using apps that are built into the TV. I have found that in most cases you can copy the setting that you came up with for the HDMI input over to the TVs internal apps. ALWAYS remember to look at some material for reference to confirm that those settings work. You can always spot check things with some test patterns that are available on our YouTube channel.
Q. Has anyone figured out to disable all of Samsung’s automatic dimming features on the newer models?
A. I personally have not. I typically calibrate those with the dimming on the lowest setting, then spot check it with known content.
Q. Is the VideoForge Pro generator is comparable in features to, say, the Six G or the Fox and Hound?
A. The VideoForge Pro generator is an excellent piece. Keep in mind that it is for calibration ONLY. It does not have the same troubleshooting and diagnostic tools as the Six G or the Fox and Hound.
The Fox and Hound alone is a great tool for troubleshooting and cable testing, but has no calibration tools built in. Just a test pattern to test a display or infrastructure.
Q. Where is ICTCP result on that HDR calibration?
A. I know exactly what this question refers to...at around 47:40 in the presentation I talk about using ICtCp as the delta formula (vs. dE2000) when calibrating HDR. When I show results at around 58:10, the delta error still shows up as dE2000 on the graph and in the final report. This is a bug in CalMAN...dE2000 still shows up on the graph even though I picked ICtCp in the CalMAN settings.
Q. On the LG you're recommending the "Cinema" preset. What about LG's ISF preset?
A. If I am calibrating two picture modes (day and night) for a client, I will use the ISF modes. If I am calibrating only one mode I could use Cinema, either ISF mode, or the Technicolor mode. All of these modes give you all of the necessary controls needed to calibrate the display. The bonus feature of either of the ISF modes is that you can lock them.
Q. We are in a small market, and have a limited budget for test equipment. Are there any patterns that are 4K files or on UHD discs that can be used for basic white balance and black level setting in UHD?
A. Yes! I am a big fan of Ryan Masciola's UHD test disc. It can be purchased here. I would also recommend that you purchase the digital files as well because he does update them fairly regularly. The disc is perfect for players of course, but having the digital files on a thumbdrive will be helpful in situations where the system does not have a disc player.
Q. What is appropriate? max display luminance 10000, 1000 or measured for HDR?
A. I use measured. The display tonemaps based off of it’s max luminance. If you set this higher than the display is capable of, the result would be lots of clipping in the image.
Q. Can my Six G be updated to 2.1 when it comes online?
A. That all depends on which hardware version your Six G is. If your FW starts with 1.x, the highest FW you can get right now is 1.87. If your FW starts with 2.x, the highest you can get is 2.60. 1.x and 2.x units are exactly the same except for 1 chip. Performance, speed, capabilities, patterns, etc are identical.
