A brief update on my journey to solve this problem in case anyone else in the forum is going through it. After 18 months of satisfying ownership, my UHD 50 started to randomly go into a half-horizontal screen as follows:

30951


This happened most often when I stopped a movie in Plex to go back to the menu. At that point, the projector would stay like this no matter what I did - even if I disconnected the HDMI, connected a different source, etc. The only solution was a full reset: turn it off and back on. Very irritating. After trying different media boxes and cables (many were quick to suggest that the HDMI cable was not capable, but that turned out not to be the issue) I was about to give up and send the unit in for repair - then I noticed that there was a firmware upgrade available. Upgrading embedded software on most devices is a hassle, but Optoma has taken it to a whole new level by requiring 3 separate upgrades (if your projector is an early build, newer ones may require two or one, mine needed 3) using 3 different methods. The three upgrades are referred to in the documentation as DDP, MCU, and 9U13. 9u13 appears to be the System software in the projector's menu. My half-screen issue went away with the DDP upgrade, FYI. The firmware files are available in the download section in the Optoma website here. If you decide to attempt this upgrade, I offer the following hints:

  1. Despite what the first document states in page 1, you need two somewhat rare cables that are readily available in Amazon, A USB-A-to-USB-A cable for the DDP upgrade and a USB-A-to-9-pin female RS-232 cable. Order these before attempting the upgrade.
  2. The instructions carefully guide through the upgrade path by telling you what to bo based on the current revision level of your projector. Unfortunately, they fail to alert you to the fact that the regular menu will only reveal the Sys and MCU rev levels; to see the DPP level you have to get into the service menu. Instructions on how to do that can be accessed here.
  3. For the last step, you will need a USB thumb drive formatted in FAT32. For Mac users, just use the MS-DOS FAT option in Discutility - that is FAT32.
  4. The software runs on Windows and requires Microsoft XML 4 SP3. If your computer does not have it, download it here and install it.
I ended up dismounting the projector and doing this on my desk to facilitate pressing the hardware buttons while removing and reinserting the power cable. This process was worth it for me - the alternative was to ship the projector back to Optoma for a $200 firmware upgrade charge plus shipping (and be without a projector for at least two weeks - no way).

Edit: It appears the firmware files were removed from Optoma's website. I am hosting a copy here for your convenience.

I hope this helps someone out there a bit...

Thanks for discussing the issue and solution for this. I don't have this particular projector and I haven't heard of this bizarre phenomenon before. I used to have an old Mitsubishi projector that had a button cell battery for memory storage. Does your projector have one? If so maybe all it takes is a quick removal and re-insertion of the battery to restore the default picture. I'm curious to know! : )

I have the same exact issue with my UHD50 projector. Its annoying. And I am losing source signal once in a while through my Denon receiver. Not sure if the receiver has anything to do with it.

However, the steps to update firmware is equally daunting to do.

When you say removing and inserting the power cable, do you actually remove the cable while the power is on? Will this not damage the PJ?

OK. I managed to update my UHD50 with the latest firmware for DDP. I think the connection issue is improved although the firmware for System is still C03 instead of the updated C05 FW. And there was a moment when I switched to Xbox the screen was half again but was pink instead of black. It was for a short while only before the full screen of Xbox home screen came on. Otherwise its working fine. My PC connection is somewhat improved as well. No more defaulting resolution to 640x480 for some weird reason. I haven'e done the second and third upgrade yet but will try to this over time. I hope I have updated it correctly as the apps clearly downloaded the FW 100% just that System FW still showing the same FW version as before.

I had to force it off to get it out of the half-screen craziness. The firmware update fixed everything - worth it! If you are hesitant to take it on you can always send the unit back to Optoma for them to do it - they charge $200 for it. The intent of my post was to try to remove the 'daunting' part from it (well, the gotchas). If I can be of any help let me know - I lived with that problem for about 5 months and it is a pain.

Does anyone still have the firmware files available for the UHD50? It looks like Optoma has discontinued this projector and took all of the files down.

That sucks. I must have the files stored away somewhere in my NAS, will dig for them. The firmware definitely fixed the half screen issue for me.

by chance, are these files the same for the UHD50X?
Hard to tell. Maybe some creative searching in the waybackmachine site could lead to the now gone Optoma firmware download page to check the file names and comp[are them to what I have. The filenames do not mention the UHD50X, so doubtful.
