On the "Information" tab the resolution should be displayed as 1920x1080. I don't remember ever seeing an "i" or "p".

I see the "i" when watching Directv, 1080i, I just never see the P when watching a BD.

Also how do I check to see if I am receiving a 24p signal?

golffnutt,

Note that the vertical frequency in the information display shown above is 23.97 Hz.
That's the refresh rate used by most 24 fps source material: they're actually slightly slower than 24 fps.

Got it, thank you Selden Ball for that clarification.

Just to note (if you didn't already know), ALL projectors display progressively. Same for flat panels. If you feed 'em interlaced, they have to convert that to progressive to display it (they're progressive displays). 1080i still has less information than 1080p (quite a bit less), but when you see a projector flash 1080i or 1080p (or just 1080), it's just an indication of the input signal, not the projected image.

So, just make sure your Oppo is set to output 1080p all the time (so that even dvd's output 1080p----the Oppo's conversion is top notch), and you're good to go.

Thank you fleaman, I did not know that, great info and I really appreciate your taking time to explain that to me. Have a great day. I'm sure we will talk again.

Hi Fellows,

One quick question. Can anyone tell me the name of the bulb manufacturer that Mitsubishi uses for this projector? Does Osram sound right? I also have an HC3000 and HD1000 too and I know that bulb manufacturer is Oshio. Reason I ask is that there is a seller on Ebay who says the bulb is genuine and the housing is aftermarket on his lamp and he says the name of the bulb is Osram. I just want to make sure I get the same genuine bulb that Mitsubishi ships without paying that high Mits price. Thank you for clearing this up.
post #6129 of 6366
The HC3800 has an Osram lamp inside, you can tell because you should see P-VIP on the back. Osram lamps say P-VIP.

Thank you Legairre, that's what I thought. Is it difficult to install the bulb in my housing and vice versa is it difficult to remove my dead bulb from my hoursing in order to install a new bulb? I've never installed a bulb, I have always bought the bulb with the housing, but is so much cheaper buying just the bulb that I thought I would try it that way if it's not too difficult. Thanks for the help. Have a great weekend.

I've never replaced just the lamp, I always replace the housing with the lamp in it. Changing the lamp and housing is pretty easy and you don't have to take down the projector because the lamp door is on the top of the projector not the bottom. My original lamp had a crack on the reflector at about 1200 hrs so I'm using the free back up lamp now. When I buy my next one I'm probably buying here http://www.tvlampsforless.com/VLT_HC3800LP_p/vlthc3800lp.htm . I've had a few emails with them and they say the lamp is the exact same Osram lamp in the OEM with the housing. Price is right so I might try it. They also said it does say P-VIP.

Thanks for that link, that is a good price but still about $60 higher than you can buy just the bulb for on Ebay and it is the orig. Osram bulb also. When this bulb plays out I may try removing the bulb from the housing just to see if I can do it without instructions. With the high cost of these lamps I am just trying to save as much money as I can. Later, and again thank you for the reply.

When I change channels my projector seems to go thru a series of changing screens 5 or 6 times before it settles down to the channel it is looking for. It will go to the blue, no signal screen, then the tv channel number screen, then turn to black screen, back to blue, back to channel finally. Is there any way to get a quicker channel change without all these gyrations? I am on Directv with a 25ft. CL2 1.3a cable from Monoprice, the best one they sold about 3 years ago. Do I need to upgrade this cable, I do not have 3D nor am interested in getting it at this time? It would be a pain to snake a new cable thru my walls if I need to replace this cable but if that will make for a better handshake then I will do it. I am using an Onkyo TX-SR 876 receiver, great receiver. I also use the Directv HR-25 500 DVR. Thanks for your suggestions. I have my Onkyo set to "Through" setting and the HR-24 500 to 1080P.

Contact Mitsubishi about updating the firmware in your projector.

It has nothing to do with the cable. When you change channels, it forces an HDMI handshake, forcing the projector to resync. My understanding is that Mitsubishi provides a firmware update which minimizes this effect.

Edited to add:
Another thing to try is to get an HDMI switch and connect the DVR's HDMI output to the projector instead of going through the receiver. Hopefully the DVR has a digital audio output that can be connected to the receiver for audio.

Cable and satellite boxes, including their associated DVRs, have the most problematic HDMI/HDCP implementations. Apparently they don't interact well with the HDMI repeaters in receivers. Often people are forced to have to connect them directly to the display device, which is a bit difficult when there's only one HDMI connector, as is the case for the Mits.

Thank you. Since it is about 4 months out of warranty any idea what they would charge me? Thanks.
post #6136 of 6366
Sorry, I don't know what they would charge. You'll have to call them.

Since packing, shipping and being without are such a pain, you might try getting an HDMI switch so you can select either the DVR or the receiver as input to the projector.

I had the same problem with this and another projector. Check if your direct TV is set to always output the same signal no matter the channel like always output 1080p or 720p. If your direct TV is set to output 1080p or 720p based on how that specific channels is broadcast(channels are broad cast in 480, 720 & 1080) then every time you change to a channel that outputs 720p and then change to a channel that outputs 1080p the projector will have to re-acquire the handshake and cause what you are describing. Make sure you set the box to always output 1080p or 720p no matter the channel. Otherwise the projector has to re-acquire the handshake every time you switch to a channel that is output in a format that is different than the one you were previously on.
post #6138 of 6366
Thanks Selden, that's a possibility. I have heard there are bad switchers and good ones. I just don't know which one to buy. Any help from any of the members here on a good switcher would be much appreciated. You guys are great. Thanks again.
post #6139 of 6366
Thanks Legairre, great idea only one problem with your recommendation, I think. My HR-24 500 Directv DVR has, in the resolution setup menu, a screen with all these resolutions listed, 480i, 480p, 720p, 1080i, 1080p. It asks you to put a check mark beside each resolution that your TV is capable of producing. Since the 3800 is capable of all of these resolutions I checked them all. Should I only check 720p or 1080p? As I am sure you already know, Directv broadcasts everything in 1080i except some PPV shows. Should I just check 1080i and uncheck everything else, and then, if I do watch a PPV (very rare because I rent redbox, much cheaper) uncheck 1080i and check 1080p?
post #6140 of 6366
Check 1080p and uncheck all of the others. That way the output signal will always match the intrinsic resolution of the projector if the DVR is working correctly.
post #6141 of 6366
I think it depends. If the projector is better at upconverting than the dvr, let the projector do it. My dvr (sa 8300) is not as good at upconverting 720p as my tv (and I assume my projector) is . I notice this on ESPN primarily on grass fields. This causes a lot of artifacts for sports.

Upconverting at the display is annoying since it takes longer to switch channels, but I get a better picture. That's the only place I really notice it. I don't use the projector much in the summer since I don't have light control, so I can't say for sure that it does a better job than the dvr.
post #6142 of 6366
Will try that, thank you Selden Ball.
post #6143 of 6366
Thank you gregoryperkins for the info. I agree and have experimented with that and my projector definitely upconverts bettter.
post #6144 of 6366
Yeah like those guys said just check one of them and the handshake issue should go away. with all of them checked you're re-handshaking every time you hit a channel with a different format. As for which one is best, like they said it really depends. With my Comcast box the projector is better.
post #6145 of 6366
Selden and Legairre you guys are great. I set the Directv receiver, and all 3 blu-ray players to 1080p and it solved all the problems I was having with handshakes when changing channels. I can't thank you guys enough, you never fail to amaze me with your knowledge and willingness to help a fellow member and I for one really appreciate it. Thank you and have a pleasant evening.

Well I guess I spoke too soon. Yesterday my handshake issues went back to square one. I don't get it, everything worked so good the day before yesterday when I changed everything to 1080p as you and Selden Ball suggested then yesterday and today so far it is blinking, flickering, changing screens 2 or 3 times every time I change channels. What could have caused this? I did call Mitsubishi and they are going to upgrade the firmware even though the warranty expired 3 months ago. That's nice of them. I hope that will fix the handshake issues. I am on FW 3.0, I guess they will upgrade to 7.0 which I think is the latest.
post #6149 of 6366
Check to make sure that the satellite box didn't change its output resolution on you. (I have a Sharp BD player which keeps forgetting the output resolution setting after a couple of power cycles. It's quite annoying, so I replaced it by a Sony for use with the projector.)

Thank you Selden Ball. That was the first thing I checked. It was still set to 1080p unfortunately. Any other suggestions maybe?
