So long as you're not playing fast-twitch games (e.g. competitive online-multiplayer first person shooters where the lowest delay/lag means the difference between you killing someone before they kill you) then you should be fine. I do play those games and I still do good and enjoy it, but I hope JVC makes the next model better in this regard. I would think you would be fine with the Wii U, just create a Custom mode and name it "Game" and turn off as much processing as possible. This will yield the lowest lag for gaming.

100" dnp .8 + X500 should be fine in a dark room in low lamp mode with a new bulb, but I'm not sure how well it will be in low lamp with 2000 hours on the bulb. My bulb is still nice and bright and I'm at ~1250 hours. If you're set on getting the dnp .8, just get the X500/RS49 from somewhere with a return policy and try it out...if it's too dim then return it. Then you will know that you will need a brighter projector (even brighter than the Sony HW55). Epson 6030 would be the next best option unless you want to spend even more money, or get a bright DLP (but then contrast and black levels may not be that great - though that black dnp .8 screen will definitely help a DLP have better contrast).

Folks w/ dnp .8 (I believe both have ~100" diagonal screens)
Andreas21
Kev1000000

Both have projectors that get pretty bright. Andreas has a super expensive pj and Kev has a super cheap pj, but they both light that material up well. I believe the JVC will work fine in the beginning, I just don't know how it will fare as the lamp ages.

Andreas has a Sony VW1000
Kev has a Epson 8350 (that was awhile back though, probably has something different now)

The only problem with the Epson's is that to exceed the light output of the Sony HW55ES, you have to use high lamp mode, which produces fan noise that is much louder than the JVC.

Quick question:

I have all of these screen samples. How do I look for sparklies? Just bright white video content - like snow or something?

Thanks,
Dave

Yep, there's going to be tradeoffs with all of them, even if you get a Sony VW1100 or Sim2 SuperLumis. But if you need brightness, you either have to deal with fan noise (or put the projector in a hush box), or buy an expensive bright projector that has a really large chassis and quieter fans. There really isn't much of a difference in brightness between the JVC X500 & Sony HW55 so if it's between those two I would get the JVC hands down. Only if you require more brightness would I get the Epson 6030 + Hush box. And if that's not an option then you may be looking to really spend a lot more in order to get what you want to achieve.

Yeah, an all white scene is the best. And make sure the screen sample is hung in the middle of the screen as that's where the light will be focused the most and where you will primarily notice it on a full screen of that material. On my screen, there's a little bit of a hotspot in the middle, but that's because I couldn't mount my projector as far back as recommended (my pj is mounted 3' closer than recommended). It will look like tiny rainbow sparkles all over the sample. And the brighter the projector is, the worse it will sparkle. I noticed this even on the dnp .8 material. The only screen sample I tested that didn't produce any noticeable artifacts, was the Stewart ST100. I would love to have that screen material in a black velvet cave.

Thanks so much!! By the way, I thought of another picture I would like to see of the screen. Do you have lighting in your room with the screen? I didn't see any from the pictures you posted, but if you do, a picture (either at night or daytime with the blinds closed for the windows/doors) with all the lights on would be a good one to check out, so that we can see how the DNP screen handles the lights.

Hey Dave,

Sorry for the delay, I was sick for 2-weeks and then very busy with starting a new job. Still very busy to be honest, but I have a "little" spare time here and there now. I replied to your PM. Just let me know which picture(s) you would like to see and I'll try to get them uploaded as soon as possible.

Respectfully,
Mr. Hatcher

My original bulb popped on my JVC X700 after ~2900 hours...bummer. :/

SAFETY NOTICE: Perform the below steps in a well ventilated area and wear latex gloves, a mask, and a ground strap!!! Be sure to dispose of the waste at an approved Hazmat site!!! Lamps contain Mercury so if you aren't confident in tackling this job yourself, take the projector to a specialist.
1) Be sure the projector has been unplugged for at least an hour, but still be careful working around any capacitors (wear a ground strap).
2) Carefully remove the failed lamp and place it in a disposables container.
3) Open up the projector (there's ~30 screws) and extract all the little pieces of glass and dust, with canned air and/or an electronics vacuum.
4) Clean the fan blades as this will help cool the projector more efficiently and will also make it run quieter.
5) Clean the glass in front of the lamp and the main lens, with a camera lens cleaner kit.
- First, blow off the glass with canned air to remove any larger particulates that could potentially scratch the glass during the wiping process.
- Hold a bright LED flashlight at an angle to the glass in order to make it easier to see any particles and streaks left behind from cleaning with the solution.
- Gently wipe the glass in a circular motion with two pieces of lint-free paper doused with cleaning solution.
- Quickly switch over to a fresh microfiber cloth and gently wipe the glass in a circular motion to dry up the solution before it has time to leave streaks.
6) Use canned air and/or an electronics vacuum to extract any leftover debris.
7) Repeat steps 4-6 as necessary...this took a few tries before I got it streak and debris free, but it's worth the extra time, IMO.
8) Install new OEM lamp.
9) While the projector is still off but plugged in, reset the lamp timer.
- On the remote, quickly press the 'Back-OK-Hide' buttons then immediately hold the 'Down Arrow' button for a few seconds until the lights on the front of the projector blink.
10) Flash the latest firmware (r1211.6).

Ok, I've been experiencing the dreaded slow HDMI signal lock issue for quite some time now...sigh/face palm, but I finally have resolve after countless hours of troubleshooting and testing different combinations of settings...FINALLY!

The two configuration changes that totally resolved my issue was to simply (A) disable 4K scaling in every component in my chain and just let my JVC X700R handle 4K scaling via MPC/e-Shift & (B) disable HDMI-CEC in every component including the projector. Only after disabling CEC on all of my devices AND disabling 4K scaling on all of my devices (except on my projector) has my issue been totally rectified.

I hope all of my thorough research and testing can help others as it has been a major pain in the you know what for me. But I'm finally able to enjoy trouble free HDMI switching and resolution changes.

Please note that each manufacturer has it's own branding for CEC, but this can be figured out by doing some online searching. The bottom link below is a good starting point.

Special thanks goes out to these resources:
