  1. Hi Allan you need to post a screen shot of the madVR OSD stats and then we can tell what is happening. My profile has a separate profile for higher frame rates where the settings can be turned down if needed (if that is the issue as Owen suggests).
  2. ...forgot to add, the Refresh Rate tweaks are not in the Bin File as it works by creating a Custom Resolution in the Video Driver.
  3. Dropped/repeated frames is a fundamental issue on how the clock works on a PC vs a CE Device. In Windows, the clock used is the Audio Clock and as a result the video must adapt to be kept in time with this Audio regardless of if the Audio and Video is sent over the same or different physical devices. That means at some point after the commencement of playback, a Video Frame will be dropped/added to keep the two in sync. This could be ever few seconds, minutes, hours, or days depending on close the Refresh Rate of the Video is to that used by the Audio Clock and how the Audio Clock will drift over the playback time. You may or may not notice this but at these points on a movie (say 24fps) there will either be only 23 frames used (eg it will drop one frame), or 25 displayed (eg one frame will be repeated). It normally looks like a stutter, but is less obvious on static scenes. So there are 2 ways to deal with this (if it annoys you). 1) Decode & Re-sample: Players like JRiver Media Center has an inbult feature called "Video Clock" where the audio is dynamically resampled to keep it in line with the Video Playback. Reclock is another filter that can be used in many players. The downside of this approach is that it only works when you are decoding the Audio in the HTPC and not Bitstreaming it to your AVR. This approach was perfect for me until ATMOS/DTS:X started becoming more common as you must bitstream these formats. If you are only running a 7.1 or lower speaker setup this approach is still a great one as you don't have any presence speakers anyway and it just "works" out of the box by selecting the check box for this option. The only other downside is the pretty ATMOS/DTS:X light on your AVR as the audio is already decoded!! 2) Bitstream & Tune Refresh Rate: This is harder to get right and each PC will be different as the Audio clocks and Video Refresh rates will be different. First play the video and see in the madVR OSD as see the estimated Drop/Repeat rate. Mine was about 1 hour on UHD @ 23.976 movies with my refresh rate autochanged set to the matching "23hz" . That is not too bad as it really be only one drop/add per movie. If you can live with that let it be. If you can not (or like to tweak) then there are various ways to create a custom resolution. madVR (which I used) allows you to do this, many others use CRU. Your mileage on this will vary. It took me about 4-hours of trial and error to go from 1 drop/repeat per movie to 0 and may even drift over time.
  4. Here is the link to my post on customising the refresh rate for 23.976 https://forum.doom9.org/showthread.php?p=1869131#post1869131
  5. Here is my settings.bin file. I've also just tuned up my nvidia settings to not drop/repeat frames when bitstreaming (will post a link from Doom9) settings.bin.pdf Edit - I had to "add" pdf to the end of the settings.bin file or else I could not upload it.
  6. ...you will also need the latest madVR from the avsforum thread I linked.
  7. I'll post the bin file later tonight. Good thing you have gone for a better GPU, the 1050ti would not cut it. You should also be able to up my settings for scaling (I'm a fan of JINC) as I'm also running it pretty conservatively. I've also 2 profiles setup to play with, one is for UHD @ 50 & 60p, the rest is for frame rates less than this as there is a big difference between the two (but you will see in my testing the settings are currently the same).
  8. I currently use a GTX1070 from my HTPC running JRiver Media Center to a JVC x7500 and can post some madVR specs later (currently running a long running sync test). Couple of points with my setup, I'm: - using the latest madVR build from this thread - https://www.avsforum.com/forum/24-digital-hi-end-projectors-3-000-usd-msrp/2954506-improving-madvr-hdr-sdr-mapping-projector-189.html - tone mapping in madVR so I can keep the output at UHD @ 8-Bit. Apart from the benefit of the high quality in madVR doing the HDR --> SDR tone mapping, you also avoid issues with the JVC Magenta Bug and needing higher than 8-bit. As our devices have the 18gbs chip, we are limited to a max of RGB UHD 50/60fps at 8-Bit, you can not do 10 or 12-bit as it exceeds the 18gbs bandwidth. - doing a fps change from JRiver (as this happens prior to playback being started, doing it in madVR does it after playback has started and is generally not a great idea). - using madVR to try to tune the refresh rate so as to not drop/repeat frames when bitstreaming the Audio (this is the current test running)/
  9. Yes I think you are correct, especially as I move this PJ around from area to area and the flexibility of the Epson is simply excellent. While I love the newer tech of the Benq, I've decided to get the Epson TW9300 and it should be here next week (the 2 Day Shipping option was only $0.15 extra!). Also, thanks to Matt and the Benq team for their time. I'm sure the W2700 will find many homes at that price point.
  10. I work up this morning and I'm still torn.... Any advice for a $2.5K budget TW9000 replacement, should I get: - BenQ W2700 : and live with the finicky placement issue, or - TW9300 : and live with running it at 4:2:0 in UHD (or even RGB @ 1080p at which point it is exactly like my dead TW9000)
  11. ...and here I go. Working out how to accommodate the W2700 already. Get a bigger screen (120" instead of the 100" I've got so I'm not maxed out on the wide end of the Zoom). Raising the screen height and mounting the W2700 "under" the shelf. I really want the W2700 but I just don't know if I can live with it. Sounds like my first Girlfriend!
  12. Firstly, Matt - thank you for your invitation to have a look at the W2700 and please also pass on my thanks to the team at Benq. They were very accommodating with the initial setup and even offered me a Lamington many times! Now onto the W2700 (and keep in mind this is a $2,500 unit and they one I was looking at was a pre-prod unit with older firmware), The Positives: - It is Bright and it is Sharp. Much more so than my JVC x7500 or the Epson TW9000. - I noticed no issue from the DLP / Colour Wheel tech at all. Looked solid as a rock - It had no issues accepting my tested signals formats such as UHD 23.976/50fps @ 8-Bit in RGB and 4:2:0 @ 12-Bit. - Signal Sync time when changing signal format was pretty good (well much better than the JVC anyway) but not as quick as a TV. - No Issue with HDR and SDR activation. - Frame Packed 3D worked out of the box (but I had to keep enabling 3D Auto as it keep changing to OFF in the menu - it was suggested this could be due to the Pre-Prod unit and the older firmware). - It is light and portable - The price is very appealing for all of the above! Areas to Note: - The team at Benq spend about 30min trying to get (including the with a test pattern) a perpendicular (not trapezoidal) image with straight (not curved) edges... and we got close but no cigar. I'm used to plonking down the PJ and adjusting the image using 4 options (Zoom, Focus, Lense Shift Up/Down, and Lense Shift Left / Right). On the W2700 there was a lot of minute shuffling the PJ left, right, tilt, etc. Alot of this This would be hidden by a bit of overscan on a felt boarder but if you are a perfectionist it will drive you around the bend. They team also wondered if it was an issue with the unit itself and while they looked for a 2nd unit we ran out of time. - There is also noticeable but steady fan noise and plenty of heat exhaust but it was on a table and I was only 50cm away from it. There was was an occasional noise that sounded like a HDD seeking from the unit. I did not notice the noise as I moved around the room Summary: I did not try to run away with the Pre-Prod unit at the end of the demo. The electronics are great and the image it beams works really really well for what I want. What is holding me back is simply the lack of install flexibility. It's relatively short throw and it wants to be dead centred and even then you have to make mm adjustments. In short, you are going to need to bend your room to fit the PJ (not the other way around). For me I really want a PJ that can be on a shelf at the back of the room most of the time, then be able to take it outside for a party and then put it back. If you are happy with a ceiling mount pole where the projector is at the same height (or lower) than the top of the screen and dead centre then you will be fine (with a screen with felt boarders). That said..... it's 1/3rd of the price of my JVC... 1/3rd! I've some thinking to do. If I can live with the placement issues then it will be a no brainer at this price point!
  13. All ready to go - HTPC, test files and cables. Thanks!
  14. Perfect! Just landed back in Sydney (a Dash8 in that storm was "fun"!). I assume it is 6/2 Holker St, Newington? Also let Dirk know he will not be needed...only small and slow members of the team thanks
  15. Hi Keith - nice cable! Not sure it would make it in time if we are looking of Friday but Matt may be interested.
