  1. ISF Calibration Photos

    Some photos of a JVC X7500 that I recently calibrated for a client and member of StereoNet
  2. There is no 'right' way to get the settings exactly right without a proper calibration. I hope that doesn't come off as me being sarcastic, it's just like many other things if you want the best performance, there are no quick easy shortcuts. If there were, people like me would be out of a job! :-) The best option is always going to be to track down a calibrator in your state. Having said that, if you just want to improve the picture and are dead set on not having your C7 calibrated, I would recommend putting it in ISF Expert Mode Dark Room or Bright Room, depending on your environment. The next step would be to use a basic calibration disc to set the brightness, contrast, sharpness, and colour. Don't use other peoples settings off the internet, what I have recommended above is far more likely to get you closer to a calibrated standard.

    hehe... I agree whole heartedly! It's a great tool for reviewing screens, but there are some other ways you can test screen uniformity quickly in the field to see if they are going to impact your measurements. I calibrated this one a little while back (for video only) and I'm pretty sure it was a flat screen. I think it's the shape of the bezel which may make it looked a little curved. I must admit I was a little surprised by the colour of the wall as well. It's not common to see this type of colour tone outside of a grading environment. Having said that, there are some very good reasons to use a neutral grey wall behind a flat panel TV (not a projector). The wall colour is going to affect your overall perception of colour, particularly if you're using bias lighting, which I usually recommend to my clients. I played around a bit with using colour on the wall behind my65" Panasonic VT30 a few years back. I finally settled on a Neutral grey with D65 back lighting. If you're interested, I still have the paint formula around somewhere.
  4. Hi nothing1, I have responded to your PM regarding this question before realising there was a thread here as well.

    Some photos of a home theatre I recently calibrated, with some seriously nice gear!

    Bwah! Missed this one, sorry Tweaky. Yes, that's correct, Home Interface/Pre-Calibration Settings/ Options: work your way through setting the correct colour gamut, EOTF and then change to 50% in the CMS. Hope it goes well!
  7. Hi Benje, Apologies for the late response, I'm just starting to catch up on everything now. I haven't calibrated any of the Panasonic OLED's yet, but they are getting great reviews and given their prior history with plasmas, I would be very surprised if they're not excellent performers. While it's not strictly necessary, it never hurts to clock a few hours on the panel before calibration, with somewhere around the 100+ hour mark being ideal. Hope you're well, talk soon... Tony

    HDR calibration is a little more tricky. The peak output of the display does not matter as much when you're using SDR gamma values (2.2, BT 1886 etc), whereas HDR gamma specifies a value of 1,000 nits. As of today, some displays can reproduce 1,000 nits, whereas others I still trying to catch up and projectors are nowhere near 1,000 nits. Through into the mix that some discs UHD are mastered at values exceeding 1,000 nits and things get even trickier. With this in mind, you want to let the display achieve it's peak light output at the top end. If you're dealing with a display that exceeds 1,000 nits there are still some very good reasons not to tame the top end. This is my take on why it's set this way. I have communicated with Tom Huffman a number of times and he's a very knowledgable guy, so you're in safe hands. :-)
  9. It's a beautiful tv @:) al .
  10. I am hoping to do another one of these soon, so I will let you know when it's coming up @Grumpy @Kensell21
  11. To celebrate the release of Sony's new A1 OLED today, I have arranged a 'live' calibration of a 65" A1. If you've ever wanted to get a bit of an insight into what happens during TV calibration and/or just want to drool over some new TV tech, you're welcome to attend. I will be at The Good Guys at Hectorville from 12.00 this Thursday 10/08. If you do come in please give me a tap on the shoulder and introduce yourself. Tony Sent from my SM-G935F using Tapatalk

    proftournesol: I don't know if I can help, but if you want to shoot me a PM with some more details I will ask around.

    Although it's hard to see the exact readings from the graph, it doesn't look like it's out by much and may not actually be a visible error. I think you did a great job srey! :-) Side panel luminance may account for the differing gamma values, I was targeting BT1886 with the last VT60's I did, which is slightly different again. Based on what I can see from the graphs, gamma (EOTF) isn't too bad at all. I think it's time for you to enjoy some movies and appreciate your handy- work! :-)

    I wouldn't worry too much about having to use the full range of luminance adjustment at the low end. I haven't done a VT60 in a while, but IIRC they did need a bit of a heavier hand at the low end. What could account for this is the gamma you started from, did you use 2.0 or 2.2 to adjust from? I would be more concerned with the +green error at 10%. If you have to settle for an error at 10% try to have it +blue, is this is far less noticeable than a +green error. As there's also a fair bit of luminance in the green channel, I suspect you may be able to ease back with the gamma adjustment at 10% if you can eliminate the green error.

    Things start to get a bit trickier at the low end, so take take your time. It sounds like what you're seeing is probably the content. Just watch your brightness and gamma, particulary the effect they have on each other. You're welcome, let me know how you get on. Sent from my SM-G935F using Tapatalk
