UNofficial Sony VPL-HS50/1 tweak thread - Page 7

Quick question--can the VPL-HS50/1 be controlled via a rs-232 or usb port so I can integrate into a control system (crestron or other)? If so, are the commands availiable? Thanks!

Wow that is really bad. I have seen it on the ps2, but never even close to that. My xbox never gives me problems at all.

Reaper, Ferret and USABrian,
I changed back to my other DVD player (Panasonic PV-D4743S) which is plugged into the same surge protector/outlet that the XBOX and HS51 are plugged into and the vertical bands went away. I tried Reaper's suggestion of turning off the 480P on the XBOX but the bands were still there. However they only appear during movies, not games. So I guess my question now is, could this be from the new cables I purchased (psyclone component) or is this an internal issue with the XBOX itself? I was hoping to use the XBOX as a kind of all-in-one unit until I can save up to get a Bravo D2 or similar unit. But it looks like my plans aren't going to work. I am glad that the issue was not with the projector. Later today I'll put my settings and some pics in the official thread.

zxlr8,

Could you tell me what cables etc your using with your XBOX?
Thanks.

Thanks Ferret,

So there is now way to control this unit other than IR?

DaveHe, I have an ae700, but I am using the xbox brand high definition kit. I am using high quality gold plated connector component cables from Radio Shack. Lol. It's the truth. For the ps2, I am using a lowere end cable. That might be part of the problem. Probably not though because I go through a switcher and I have a 25 foot component cable from monoprices.com that attaches to the projector. So that is a bout 30 feet of cable and o banding on xbox but some on ps2 in 480p. I still use 480p on the ps2 sometimes because it is hardly noticeable.

Supposedly you can control the HS51 (not HS50) from the Ethernet port on the front, but good luck with that. I could never get my HS51 to connect to my router or my PC using this port. Packet sniffing software never showed any packets coming from the MAC address of the HS51. Someone else reported similar problems, and I don't think anyone has reported success connecting via this port. As far as I can tell, the USB port is only for setting custom gamma using the included software, but I did connect to it successfully.

The protocol manual is no help. It just says to connect the PJ to your router, power everything up, check the IP address in the PJ status, and away you go. The only problem is it doesn't work. The PJ never connects to my router and as far as I can tell never broadcasts any packets to even attempt it. Unless there is some trick to make it work, mine is non functional. Not a big deal to me since I was mostly just curious to see what it could do, but it could be to people who intend to control the PJ from a PC.

Not sure if this will work but it expands on what Ferret is saying. Take a ethernet crossover cable and connect to the HS51. For this to work you will need to configure the network connection on your PC to be on the same IP subnet as the HS51. You may also need to mess with the speed settings since I don't know if the HS51 ethernet port is 10Mb, 100Mb, full or half duplex. Maybe if I can dig up a crossover cable I'll give it a try this weekend.

Just curious...Has anyone done a Colorfacts or SMART calibration yet. I know someone has done the SMART one but I didn't think they had done the filter.

The choppy or strobe motion in the beginning Gladiator battle scene is by design. IIRC it was filmed at a higher frame rate with no motion blur. I believe king Arthur was done the same way.

Has anyone bothered to play around with the settings in the Black Level Adjustment menu? I currently have it on High, which the manual states: "Gives higher emphasis to the black color". After calibrating Constrast in the Digital Video Essentials DVD I see no black crush, everything looks good.

Is Black Level Adjustment set to HIGH a big no-no?

I have Picture mode in cinema, contrast at 90, brightness at 55, color at 40, hue at default, sharpness at default. All settings calibrated via DVE DVD on a Da-Lite High Power 106" diagonal screen. Projector is table mounted and I'm using DVI a 1080i via OPPO DV971H.

Any recommendations? Still debating whether to get an IMX lens. I am noticing SDE more and more (viewing at 12.5' from screen).

I understand calibration of the PJ for dvd content using Avia or Video Essentials, but how does one calibrate for say HD content from a satellite reciever ? Is there any method for this ?

I find that by using the black level on high and the brightness turned up that it removes a bit of the "wash out" effect on the screen. I too use it on high and aftor calibration, I don't have any black crushing either.

The black level does not appear to alter the IRE setup at all; when calibrated with black level set to high, there is still a distinction in the 0 IRE of the pillarboxing and the 7.5 IRE of the material when veiwing TV source.

I just received an HS-51 for a friend of mine and am anxiously waiting to start setting it up. I probably won't get started until this weekend. I have Colorfacts with the Eye-One spectroradiometer? and will be doing a full ISF setup after we get some hours on the projector. We will be running HDTV/TV from a Time Warner Cable box on the component input, and DVD via HDMI from a Denon 3910. After reading all the posts on this and the other HS-51 threads, I am really looking forward to firing this thing up. As soon as I start getting some results I will definitely share with everyone.

mintakaX:

You will need a High Definition video pattern generator such as the Accupel HDG-3000 in order to fully calibrate for any high definition sources.

Link:http://www.accupel.com/

Is the Accupel system what ISF calibrators use, or is it Colorfacts? Which is more "professional", Accupel or Colorfacts? My reasoning is: why not just pay $300 for the in-home ISF calibration, rather than $1500 for accupel/colorfacts?

Any thoughts from the gallery?



S.Anderson

Is it possible to use the patterns generated by a DVDO HD+ to do the HD calibration ?

I did everything you describe except mess with the speed settings, but I still never saw any packets from the PJ and could not ping the IP address displayed in the status. I wish you luck. If you figure out how to make it work let us all know.

Rieper,

Sorry about the delay on this response but I had some interruptions for my real job that I had to attend to.

Unfortunately, you need both. There are several other products that do this as well but I am most familiar with Sencor and Colorfacts products. The Colorfacts software, along with either the spectroradiometer or the trichormat-1 sensor is a system that allows you to measure the amount of red, green, and blue light that makes up a displayed picture. When you do a greyscale calibration you display the range of Grey from 0 IRE to 100 IRE and track the proper "white" level across the range based on the output of your color sensor. If you are calibrating for a DVD input, you can generate the proper test patterns from a test disk such as Avia or DVE. The Accupel, or similar device from Sencor can output test patterns at 480i, 480P, 720 P and 1080i. This probably does not make much difference for greyscale patterns, since you could pretty much transfer your results settings for the DVD input to the HD input and be quite close. If you are looking for the best possible picture for the HD input then you should calibrate with signals with HD quality on the HD input. If you are trying to find out how well your display handles HD resolutions, etc., then you definitely need an HD signal generator. Colorfacts will also allow you to generate the correct greyscale patterns but I have not tried using them with a PC and an HDTV capable video card.

And yes, for an end user you would probably be better off having an ISF tech calibrate you display for you.

mintakaX,

I am not familiar with the test patterns from the DVDO HD+. If it outputs the 0 - 100 IRE patterns, then you should be able to calibrate for proper greyscale. The big question concerns whether these patterns are traceable to a proper reference. The AVIA and DVE test disks, as well as the HD signal generators from Accupel and Sencor, provide a solid reference to the same NTSC and ATSC standards, so that various displays can be repeatably calibrated correctly to a "reference", and that, ideally, they will all display the same color of grey when done.

How is this exactly tested? For me 72Hz is never an issue, especially for HDTV were you can't use reclock to upspeed the movie from 23.976->24fps
due to the fact dvxa has to be enabled for smoorth playback. So how does it perform on 71.928 (3x 23,976)
And of course what are the results on 75Hz refreshrate

thanks in advance

Does the Sony VPL-HS50/51 allow for switching between Standard Definition (SD) Colorspace , BT-601 , and High Definition (HD) colorspace , BT-709 ?

If it does not then one must be careful when calibrating this PJ . Sending a Test Pattern or Color Bars from a DVD (SD) through to the PJ will result in a 720p image with SD colors . Sending a "true" HD signal from a Satellite or Cable feed or HD-DVD (as in WMV-HD) will also result in a 720p image with SD colors .

If it does , then seperate calibrations would need to be done for the two different colorspaces , SD and HD and saved into different memories .

If the DVDO IScan-HD+ or the Accupel HDG-3000 are not changing the colorspace when they are scaling the image , then we are still only seeing SD colors and not all the benefits of having a HD PJ .

Someone in the Panny 700 thread mentioned having this option in the menus , but I can't locate it in the Operator's manual . Someone else mentioned here that they had spoken to a Sony Rep and that this might be a possibility in a future upgrade .

For those using HTPC's , try downloading this chart and see if you are getting SD or HD colors... http://www.belle-nuit.com/testchart.html

Just my 2 cents worth ,

1280x720 @ 50 Hz seems to work (but no : yes !) 1:1 pixel mapping


50 works fine
