    This evening I watched the remainder of Braveheart. Please note, I only watched the first 20 minutes earlier in the week to assess the 4k quality.

    This evening's viewing affirmed to me two things...

    First, and your opinion may vary, Braveheart is one of the greatest accomplishments on film. It is my favorite film of all time.

    Secondly, it was well worth my hard-earned money to invest in 4k projection. That was confirmed to me tonight as I watched a film I had seen dozens of times prior, but seemed completely fresh to me in this viewing due to its picture quality.

    The landscape photography looks breathtaking. The close-ups of faces look stunning. 4k resolution really brings color and detail into the picture like never before. I can finally see it. I can finally appreciate it.

    Ron,

    How are you playing your movies?

    The sync should only take place when the resolution or frame rate changes. Whenever I play UHD (or BD) movies from a disc from my disc player there is ZERO sync time after hitting play because the disc menu is always the same resolution and frame rate as the movie. This is on the JVC RS600.

    If you are playing some sort of streaming source, then maybe the “menu” screens are a different frame rate from the movie (60 vs 24) or different resolutions? But if you are playing major studio UHD discs I don’t see why this would be happening.

    Not normal. Not for me. And I don’t think I have any special implementation for my playback.

    Guys,

    Not playing from a streaming source.

    Never had this sync issue until I started using the JVC last week.

    On AVS, I am being told this is normal with JVCs, whether you are experiencing it or not.

    It was recommended I go into my Oppo menu and change the resolution to UHD 24MH.

    I did that and still have sync issues that cut into the first few seconds of a film.

    Not sure why at this moment. Not sure if it is fixable. I am having the projector calibrated in the next few weeks so I am certain Gregg Loewen may be able to assist in this matter.

    It is normal whenever you are changing resolution or frame rate. If your menu is, for example, 1080p60 and you hit play on a movie that is 4K and/or 24p the HDMI will resync. But if your menu is the same resolution and display rate as the movie there should be no handshake resync.

    I think some have their setups configured in a way that something changes between disc menu and movie playback, thus causing a new handshake resync at the start of a movie, and they think this is the way it is for everyone. Because everyone will experience this resync with source/resolution/colorspace/frame rate, etc... changes. I get them every time I put a disc in the player and it changes from the player menu to the disc menu. And again when I hit stop and leave the disc and go back to the player menu. But it doesn’t have to happen when you are starting the main movie from the disc’s main menu.

    When you have disc in and are on the menu, what is the projector showing as the resolution and frame rate for the menu? And then what is it showing for the movie you play? For me, they have always been the same and there is no resync blanking. Any time I change source where there is any type of resolution change or display rate change then I absolutely will have a blanking out while it resync, but this doesn’t happen for me when playing movies because the movie menus are the same resolution and frame rate as the film.

    Here are some quick pics I just took. Note: the menus display the same 4K(3840)24 resolution and frame rate as the actual movie. If I can figure out how to post video here, I can show you not a second of the studio opening logo is missed when hitting play from the menu. Because there is no resync in these cases.

    The first picture of each pair is the menu and the second is the main feature.

    64866434-65C1-49CE-8FA2-5A02F6835EFB. 7619BAC5-B4DA-4851-B40C-FEB1EE600178. 0B7DB480-2E0F-4529-8666-2203BCD15E4D. 9B606A86-4853-4346-96B8-049993382E32. F9E0C01D-B393-40E2-BD80-E8EB0841B93B. B996151A-3ABB-4613-9C34-5054B5482F6C.

    Now, when I first put a disc in the player the player’s access menu is 60p. So there will be a resync and blanking when the studio disc info first starts up. But that is like the “Disney DVD” promotional stuff. The studio brand advertisements at the start of the disc. This is because it is changing from the player main menu at 60p to the disc video which is 24p. But that resync is over with once you get to the movie’s main menu. So everything should be 24p on the movie’s main menu (and that should be the same resolution as the feature). So no resynching should happen when you hit play from the menu.

    Maybe there is some other difference between different setups not being accounted for? Something different that would result in a resync for some but not for others depending on settings? Anything that changes between the menu and main feature could do it. Resolution, frame rate, color space, HDR v SDR, etc... I am using the Panasonic UB820 and I do the tone mapping in the player. Maybe there is a difference if you are doing the tone mapping in the display? I’d need more time to experiment with that though to see if I can set my stuff up in a way that would trigger a handshake going from the disc’s main menu to the feature.

    I’ll post back if I figure anything out with that.

    Hi there. I am looking for my first PJ.

    I'm wondering what option would be best for the following.
    120" screen.
    Pretty dark room... not 100% used for a theater, but I specifically want movies to look their best with the lights out (good blacks).
    HDR / 4k signal acceptance
    Good detail in resolution

    I know real 4K starts around $5,000, which is not in my budget! I'd say up to $2,500 at the most, but prefer to stay around $2,000.

    I see the Epson 5040UB. I'm told the issues with the power failure are resolved... but who knows.
    Optoma UHD65
    JVC LX-UH1

    First row will sit around 6' from the screen. So I'm thinking Seymour AV Center Stage UF for this.

    Please help me figure this out!! Too much research just makes things harder!

    Guy,

    I hear great things about the Epson projectors. If I was looking for a budget 4k PJ that would be my choice.

    I hope others chime in here as well.

    Thanks, Ronald. Any choice for screen material sitting that close? It has to be acoustic transparent.

    I have the Epson 5030, which is the previous version of that projector - the 5030 was an HD projector, whereas the 5040 does 4K through pixel shifting. HTF's own Bob Furmanek does have the 5040 and I had a chance to see it in action in his home. I was very impressed with the quality, particularly for 3D presentations.

    I think you can purchase an Epson with confidence.

    Can't help you there as screens are not my area of expertise.

    But jumping back to Epson, I have also seen it in action and I agree with Josh that your purchase of one would not be disappointing.

    Good luck with your eventual HT setup. Please keep us informed as what you buy, and especially, your initial thoughts.

    Looks like prospects are not too good for an affordable true 4K projector using a laser light source.

    I was kind of holding out for something like that.

    Have to admit that I sort of got turned off of JVC when I bought an RS2U then found out that JVC had fucked up the colour management, then wanted 1500 bucks for a modfied DVDO processor to allow a person to fix a problem that they had caused in the first place. I got turned off of any DVDO product when they told me that my supposedly "futureproof" processor couldn't be upgraded to add a colour management system, even though it was the exact same model that JVC had modified to allow their fuck up to be fixed.

    Short of a couple of visits and samplings at a home theater specialty shop, I live vicariously through posts like these.
    Congratulations, Ron...No doubt, 4K living is a beautiful thing.:cool:

    I’m just reading the discussions and counting my
    pennies.

    But I also now discussing new hardwood flooring, which might take precedence over 4K. So I enjoy the research and see what develops this year.
