Great! Not bad for $25. Is there a different calibration test you would do for SDR 1080p? Do I need any special hardware (meters) to calibrate the brightness, contrast, and sharpness?

Free HD test disc/files here on AVS Forum:

Calibration and meters are an entire section in AVS!

One simple meter that is useful is a light meter so you can maintain a consistent 14-16 foot lamberts light output as the lamp ages. Thread one of several on AVS:

This thread hasn't been active for a while I see.

Who still owns this projector? How have you liked it? Who owned it and got rid of it? Who auditioned in, and went with another projector all together? What did you audition it against?

Trying to chose between a BenQ 3550 (recently bought, still in box, paid $1680.88CAN after taxes) and the JVC LX-UH1 which was newly suggested to me as an alternative to the Epson 4010. There's not a whole lot of info out there on this projector. VERY few reviews or videos of hands on experiences with it. Hoping you guys can shed some light and help in my decision.

Here's a couple of French reviews (if needed use google translate for language of choice):

TVSPro blog review:

and the youtube comparison review:

I would investigate replacement lamp costs before making any decisions, but the reviews seems positive.

Hi there. I currently own the JVC. I didn't audition the 3550, but did a lot of research.

Fair warning- this is my first projector. I put that warning up there so you can take my comments for what they are, not terribly experienced.

I had help selecting it from a professional installer. He specifically told me to BENQ and Optoma because I wouldn't be happy with them. As a professional, he did mention he did not like what he saw with those, but did like the JVC.

He did not sell me the JVC.

I like the JVC, but there are few things I'm not so crazy about.

From my experience around 20-30 hours.

Movies: Looks good. 4K HDR looks pretty decent, but it obviously won't compare to a TV set. It's nice and sharp.
Blacks are probably on par of what is to be expected... Color is nice, and have been told by others watching on my screen that it looks 'perfect' at 100" (they are also inexperienced with PJs)

Motion is a big annoyance for me. Watching 24p movies is noticeably choppy. I may just be sensitive to 24p content. There is no motion interpolation at all. So panning shots are blurry and or choppy depending on the object. This is probably true of other PJs too, but this is my first. This may also be the result of inexperience.

Games: Looks good too. There may be a slight delay in controls, but I hadn't really noticed it. There is no blurriness or choppiness (word?) when gaming. My output on my HTPC is 60hz, matching the PJ.

Sometimes when switching from HDR to SDR and back and forth constantly, the PJ makes a cranking sound. Kind of loud-ish. It might just be mine though.

I haven't tried the 3550, but people seem to like it.

HTPC running JRiver w/ Mad VR.

I tried switching over to SVP Pro, which helped slightly, but had HDR issues.

I have a Sony BDP, but I don't remember if I tried it or not.

Doesn't Mad VR have a frame interpolation feature?


I don't notice 24P movies being especially choppy on my UHD50 via a UBP-X700.

No, it is not frame interpolation:
https://wiki.jriver.com/index.php/Ma...#Smooth_Motion

A few lines explains why.

I have my player change the desktop refresh rate to that of the video.
So if the movie is 24p, then the PC tells the JVC to switch to 24hz mode.

I think maybe it's just me... however, I don't notice this watching the same source on my Sony X930E.

There is a shot in The Hobbit where they're explaining Dwarfs in the beginning of the movie. They pan around the inside of the mountain.

On my TV, it looks pretty good. On the PJ, it looks very blurry. It's hard to watch. Maybe I'm sitting too close?

I don't use MadVR, so I can't comment from experience, but have you experimented with smooth motion to see if it helps, also do you get the same effect with your BD player?

I haven't experimented too much with it. I may give it another shot.

I don't think I tried my BDP yet. I'll pop one in and see how that goes.

I have an Apple TV I could also try, so I'll mess around with it.

Overall I really like the PJ and screen (with 7.4.1).

I haven't had time to watch a lot of movies just yet, but checked out scenes from a bunch. I am happy so far!

Lx-UH1B review

Hi, I’m knew to this forum. I purchased a JVC LX-UH1B projector 3 months ago. Due to a fixed projector shelf position I needed the JVC LX-UH1B‘s vertical lens shift capabilities. This meant the Optoma UHD65 was not an option for me . I narrowed down my options to the JVC LX-UH1B and the JVC NX5.
I was able to trial these 2 units side by side at the shop to make a decision. The NX5 was double the price but I was prepared to pay this if the picture was vastly better. During the A/B comparison I noted that the resolution of the images was near identical. With images paused and standing directly in print of the screen there was no discernible difference.
So the e-shift does an admirable job. Contrast was by far better on the NX5 especially in space scenes. Overall sitting back at viewing distance and just enjoying the movie I got more wow factor from the JVC LX-UH1B, possible due to more brightness and more vibrant colours. Although contrast was better on the NX5, it was reasonable on the JVC LX-UH1B. The bulk and weight of the NX5was also a factor
as the unit would be mounted above our heads. The benefits were not worth double the entry price so I decided to go with the JVC LX-UH1B.
When I installed the unit at home, I noticed 2 things that had not been apparent in the showroom. The light border was very apparent and distracting. This was not evident at the showroom as their screen was sitting some distance in front of a black wall so the light had a chance to absorb and disperse.
Second issue was the noise. Again quite annoying. The noise is predominantly due to the e shift mechanism. Turning this off is the only thing that drops the noise levels appreciably. Eco mode has minimal effect. The image quality is excellent, and with iris on high the light border is less evident. It’s only an issue in uniformly dark scenes. Bright scenes or mixed contrast scenes it is hardly evident.
I contacted JVC Australia but ultimately they stopped replying to me as they most likely don’t have a solution. The light border is ashame as it is the only main drawback of an otherwise excellent projector. I’m surprised Texas Instruments would release such a flawed chip. I received no response from an email to them. I don’t know why they have so many unused pixels unless the unit is dual purposed for something else?
Anyway, I don’t have an issue with the above as long as the buyer knows about these weaknesses before hand and makes an informed decision. Unfortunately I had not read this entire thread before my purchase and as has been noted there are limited English reviews on this projector.

The light border can be minimized by a dark frame, and so at least it can be mitigated. On my grey painted screen and UHD50 it is nearly invisible most of the time.


Excessive noise from the XPR actuator is a defect and my UHD50 is almost completely silent. Perhaps, JVC or the dealer would allow an exchange for another unit, possibly a refurb.
