  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Is in the house! Here is the manual. Photo of it after taking it out of the box. Wish it had a remote, the buttons on the side are a bit akward to use.

It was hand delivered by Sharp yesterday. This is from the first production run, not one of the pre-production units that have been floating around.

I was able to drive it at 3840x2160p30 from a Dell laptop yesterday as well as 3840x2160p24 from an OPPO BDP-103 Blu-ray player. The OPPO scaler is better than the one built into the Sharp when using my new scaling test pattern. OPPO has a non-ringing scaler.

Now I need to find a laptop that can drive at 60 Hz. Jeff? I am considering the HP 8770w. It has a Kepler GPU and claims DisplayPort 1.2. Also need to find a DP 1.2 KVM. Finally I need to swap out the Quadro6000 from my SCRATCH workstation with a new GPU. I will probably go wtih the GTX Titan for now.

Anyone know if a MBP Retina can drive 3840x2160p60 over DP? The website says max is 2560x1600. I am hoping if you only output over DP that you get the full resolution.
 
Nice Stacey. I'm highly interested in this monitor. I'm about 2 months out from getting one.
 
It supports 3840x2160 @ 30 Hz over single HDMI and 60 Hz over dual HDMI. It also supports 60 Hz over DP 1.2. If you send in other resolutions you can view dot-by-dot or scaled to fit.

You don't need BM. As mentioned above, I was able to send 30 Hz (full resolution) from a Dell laptop over DP. I am now looking for a laptop that supports full res at 60 Hz. All Kepler based NVIDIA cards can send 24 and 30 Hz over HDMI today as well as 60 Hz over DP if it has 1.2 out. At CES Sharp used a FirePro card as well.
 
I have one of Iogear's 4 port 2560 x 1600 KVM's - running at 2560 x 1600 and I'm very happy.

This one is 4 port displayport supporting 3840x2400.

One thing I've heard, which may be incorrect, is that the displayport IKVM's cannot fool the computer into thinking there's a monitor connected to it (which you are switched to another computer).

I'd like some feedback on this issue?

BTW - the monitor for my video server is a Sharp, and I've been very happy with it.

Well, ... damn, that is ... um .... up until I just read your post which totally destroyed my satisfaction with my older Sharp.

How do you like the Oppo? I've been considering getting a http://www.oppodigital.com/blu-ray-bdp-105/# that I could output to some XLR-connected powered JBL LSR8's, JBL sub-woofer, etc. - and have it act like a receiver in that it would switch the inputs for me.
 
The IOGear says 3840x2160 on one page and then says DP 1.1a on another. I will send them mail and try and get more information on it. I currently use a DualLink DVI IOGear KVM that I like.

I like OPPO. I have worked with them for a long time. They bundled my first calibration/test disc with the 83. Any feedback you have on their products, they take to heart. If it is a bug, they go out of their way to get it fixed.

As you write calibration software, what are your thoughts on auto-calibration, where an i1Display Pro (possibly a low end device for the 4K market?) is used to program the set's internal LUT after being told (luminance, sRGB or rec709, etc. - or custom x,y values, gamma, white point and luminance).

Also curious what you think of JBL's LSR4328 auto calibration when combined into a 5.1 system with JBL sub-woofer?
 
CalMAN is doing a lot of auto calibrating these days. I have not tried out v6 yet. I know their 3D LUT box is getting better based on feedback from someone who has been testing it.

I have not used an i1 in a long time. Most of the time I use a PR655 or CS200.

I figured you'd be much higher up on the calibration food chain!

Way more than I'm willing to spend for calibration.

Just bought several DELL U2713H's with i1Display Pro auto calibration of internal 14-bit LUT.

Those are a step up for me from older Samsung CFL monitors, but ... no doubt a step down for a serious colorist.

A thought occurred to me.

Our eyes adapt to fluorescent and other lights, and we see what we identify as white, even though it isn't.

After I turn my green screen lights with green filters off, the colors I see with my eyes are massively tinted.

If you wear up-side down reversing glasses for a week or so, you brain will actually flip your vision so that you see up-side down if you take them off (luckily for the test subjects, not permanent).

If the brain adapts so readily, where colors are perceived relative to other colors ... and I know this is heresy ... is such attention to detail, getting those last few percentage points right for gamma, white, point, etc. really necessary or useful?

That's a fair question. I would say that its important that grayscale should match from 0% up to 100%. The overal absolute value is less important as your eyes will adapt. I also believe DeltaE is valuable.

Its difficult to calibrate a plasma because of voltage regulation. Our equal energy patterns solve that problem for gamma, grayscale, and gamut.

I don't think people realize how important contrast ratio is from pixel to pixel. For anyone who has seen a Dolby PRM will know what I am talking about. The depth that the high contrast ratio adds to the image is like nothing else I have ever seen.

Thanks for the tips!

What kind of panels give the best 'real' contrast values (not the crazy ones the manufacturers claim)? Are you saying that plasma is the way to go?

What techology does the Dolby PRM http://www.dolby.com/us/en/professi...0-professional-reference-monitor-details.html use? I coudn't tell from their description, but it looks like one hell of a great monitor!

My understanding is that the IGZO display technology uses edge-lit LED's. Is that a viable technology contrast-wise?
 
Good stuff Stacey. Give us an update and more eye candy to oogle. How's it running? What's given you the most eye-pleasure so far? More photos? Ordering details?

The works. Spill the beans. You've got one of the best toys on RU right now.
 
Any updates? a sharp sales rep told me it should be out in the US mid April.
 
As of today you can order from Zones.

I have to send mine back this week to be swapped out. We are using it for a presentation Ted is giving tomorrow showing Windows running 4k multimon. We have a 55" (can't mention brand) and the 32" Sharp.

I have tested with three different laptops and each one is limited to 30 Hz over DP. Dell M4600, HP 8720, and HP 8770w. I love the desktop space.

The buttons to switch inputs, access menu, etc... are on the side of the display and are not convenient to use. Its kind of a pain to switch to dot-by-dot for example.

Its been more of a challenge to use the GTX Titan because I get lots of TDRs trying to run Scratch. The NVIDIA drivers are pretty poor at this point in time. :)
 
Just on the CalMAN site the other day looking at some bundles they're offering.

Have also used the i1 - its way better than no calibration at all, but I don't consider it precise enough for professional CMS applications.

Have been using the AMD Radeon 7970 graphics board to drive the Sony ES-1000 4K "home" projector off a GlobalStor Extreme-DI windows box. Looking forward to 4K and UHD resolution becoming standard fare on all the upmarket and gaming GPUs, not just on a few specialty cards.

Cheers - #19
 
GTX Titan *should* run the display at full rez, 60Hz. I was supposed to be getting one of these displays, but had my vendor put the order on hold. Going to see what shakes loose at NAB, if anything, but I may take delivery after NAB. I am also finding the Titan drivers to be pretty much crap at the moment. It's difficult to even benchmark or review the card properly at the moment. :/
