The PS4 causes odd horizontal lines that are correctable with the keystone, I also have HDMI sync issues with the PS4. None of the other systems game me a single hiccup. Never had a PS3. I just figure playstation and Optoma don't get along too well.

I haven't had any issues with my HD20 using my PS4, PS3, PS2, PSone, Xbox 360, Wii, and N64,

I no longer have my HD20, but I didn't have any issues with the PS4 using HDMI via my Onkyo receiver. No lines or anything. No keystone was being used. I wonder what would cause the lines with a PS4.

I run it through a pioneer vsx720. I get a horizontal line occasionally at the top and I frequently get total snow when powering everything up. Keystone correction 1 step and then back corrects the line and off/on on the receiver corrects the snow.

I forgot I have a darbee in line now but I was running that on the 360 and One with zero problems.

Gaming

Hello all!

I have had this projector for over a year now (got it for a great price on craigslist) and I am currently building my first gaming PC. I was wondering how well this would work for gaming, as I see in the specs that the refresh rate is 24 hz to 85 hz. 60 hz will be the least needed to game without seeing lag. I do not if it will scale for what is needed, but from what I see most things play automatically at 24 hz. Is there a setting to get it to be at 85 hz?

Thank you for all the knowledge you can offer,

Dylan

I used my HTPC with the HD20 for gaming as well as with consoles. Works great. I was running video and audio via HDMI on the Video card. Running at 1920 x 1080 60p. I prefer V-sync enabled to prevent tearing. Unless your video card has special settings or you have special software, Windows will run at 60 hz. I haven't found any included way to increase that. Also, I am pretty sure the HD20 won't actually run at 85 hz with regular 2D input, just like it doesn't actually run at 24hz. When at 24 hz, it is actually running at 48 hz using frame doubling. I would have to find the source again for that. But not sure about the 85 hz part. I thought that was for specific 3D formats. But again, I haven't found a way to get Windows to output over 85 hz over HDMI. At least not with included software or with the ATI or Nvidia control panels.

I have no complaints with the PC gaming at 60 hz on the HD20 or any of my LCD panels.

Hi folks,
I have had a projector for about 10 years, started with an Infocus X1, then had an Infocus 4805. The light tunnel recently collapsed for that projector, so I’m without one for now. My budget is limited to $300 - $400, so I will need to go used via either ebay or Craigslist. I did a little bit of research, and it seems like the Optoma HD20 might be a great choice for me. My main point of posting here is to check and see with the experts whether this projector is the best choice for my situation, or if another projector might be a better fit.
My projector is in the basement, so I can control the light. The main thing it’s used for is either watching movies via DVD/Blu Ray or watching sports. My current screen is a 80” diagonal painted tileboard screen with Velvet border. Projector is 11 feet from the screen, and the main seating position is right under the projector.
I definitely want to go bigger with my next screen, how big is the question. I am thinking 100” so I can use the same method I did before for building the screen, but I can use another method if bigger is better. A limiting factor is where the projetor is currently mounted. The total basement ceiling height is about 92”, but the projector is mounted under the center beam which brings it to about 80”. So, if I go bigger than 100”, the screen bottom will be getting too close to the floor.
Do you guys think this is too small of a screen for an HD20? I plugged in the information to the Projector central calculator, and it says it will be 29 fL. Does that calculator use eco mode or full power?
Any other suggestions anyone has would be appreciated!

Here are my latest settings that I was using (no longer have my HD20). Screen is a DIY 125" 16:9 1.0 gain white matte blackout clothe screen.

Here are the menu options from my HD20 with the settings that I used for all sources. BD, PS3, PS4, xbox 360 PC and more. I only used the HDMI and VGA inputs and rarely the VGA input.









Enjoy.

Obviously people have different preferences, so you may not like my settings. I like fairly neutral coloring with preference to sharpness with as little artifacts as possible. And with preference to shadow and highlight details. Which requires contrast that my be low for some people. Either way, this should be a good starting point.

Unhappy Projector won't power up

Hi Guys,

I've had my Optoma HD20 going on 5 years now, and it worked superbly during that time. However, last night while watching a movie the projector just cut off, no popping, no crackle, nothing. There were no light indicators either. I unplugged it for a while and plugged it in and the power light came on as usual solid amber as if in standby. But when I try to power on it just starts flashing amber, and nothing else happens. No lamp or temp led, no fan, no bulb light, just the power light flashing amber. What could be wrong with it? Is it possible I can repair it myself?

N.B. It might be helpful to know that when the projector is connected to power the computer it is connected to via HDMI detects it is plugged in as it usually does. May or may not be helpful I don't know.

Thanks in advance to anyone who can help

Anyone with an assist? I scrapped it down to the point where I removed the mainboard and vacuumed the inside, which was quite unnecessary, for a projector I had for quite a while it had absolutely no dust build up. Looked brand new on the inside. Needless to say, I put it back together and it's still not powering up when trying to switch it on.

I have almost the same exact problem, but when I press the power button, it begins to blink green, but no fan spin up, no noise, and it stays in that blinking condition forever. This is the "warming / powering on" state, according to the user guide. But nothing is happening.

Blink green? Mine blinks amber, not green. Probably two completely different issues. My amber power light blinking alone isn't even in the guide. So no clue what that means.

Hi everyone - I've had my Optoma HD20 for a long time and have put more than my fair share of usage into it. It is my first projector and the bulb has finally died in it. Can anyone point me to a good place for a replacement bulb? I've searched Amazon and a few other sites and most of the "replacements" have terrible reviews that they fry within a few hours, etc. I don't really have a local home theater store around to see if they have contact with a rep from Optoma.

Hoping to find something online and I don't mind pay a little extra to ensure that I'm not getting something that will break within a few hours. Thanks in advance for all the help!

Some people have ok luck with 3rd party bulbs. But I simply don't trust them. And my suggestion is to stick with the Optoma OEM bulb and housing. Unfornately searching for OEM will list mostly 3rd party units. The bulb may be OEM in many of them, but the housing assembly is not.

Propector People (I don't work for them or any PJ company) sells Manufacturer bulb/assemblies.
http://www.projectorpeople.com/searc...r.brand=Optoma

If you have the BL-FP230F bulb part number, then the price is $217 right now.

B&H is the cheapest I have seen so far for this unit from an authorized seller. $180 http://www.bhphotovideo.com/c/produc...610ST_And.html

Amazon has it slightly cheaper, but no reviews so I don't know if it's the true bulb, but the price is close enough to be true. And it's shipped by and sold by Amazon, so it should be the right one. http://www.amazon.com/Optoma-BL-FP23...ords=BL-FP230F

The bulbs that are under $100 are simply not the ones to buy. And remember to find out the exact part number when you look at yours.

Hi everyone, First let me apologize for my English, my OPTOMA HD20 got a spot in the middle of the screen , it's just dirt or may be something else ? I made a clean sweep of the lamp but this apparently normal. If someone has an idea what might be happening I thank you.

You are using a cheap 3rd party bulb and that has melted the plastic lens internally. Others have had this issue a few pages ago. If you look back a few pages, you will find pictures of the issue.

You need to replace the plastic lens, clean the fans, and replace the bulb with a true OEM bulb that runs about $170-220. If you keep using the same bulb housing you have now, then it will happen again.

I recommend replacing the plastic lens with a glass one.
http://www.ebay.com/itm/Optoma-HD20-...item2ed8c56946

You might be able to keep the current bulb if you use a glass lens. But the burn mark means there is too much UV radiation in the light path and something else might get damaged from the heat in the future.

Did you ever find out what is wrong with yours? Mine just started doing the EXACT same thing yesterday. No fan start up, no lamp coming on, no noise at all...just a blinking green power button. That's it.

I took the bulb out, replaced it, changed out the power cable, plugged it into different electrical sockets all trying to find some odd reason why it would be doing this. The results were zip zero zilch. Nothing. Constant silence and green blinking power light.

I hope it isn't completely busted and ready for the scrap pile =(

I have replaced the bulb in my projector once before. Last time it poppe really loud but also exploded. I had to get all if the glass out

Last week it popped again but the led light for the bulb did not light up. The led light stays red when I try to power the projector on and will not turn on.

I bought another bulb and after trying to turn it on. It still will not turn on

When I plug the projector up I get a blinking green light. When I turn the projector on it makes no noise ... But after a few seconds of hittin the power button the blinking green light stays solid red


What's going on. I hope my projector is not dead


This last time it popped my projector stayed on and made a really loud humming noise. It soused like electrical waves lol

So I had to unplug everything


What luck

Hot Spots on faces

Hi Everyone,

I recently replaced my bulb with an official Optoma lamp for my HD20, but I'm noticing that areas around face cheeks and noses are showing hotspots.. There isn't a smooth gradient from hotspots in these areas and I have to really lower my contrast settings to make them go away. I noticed this happening as my bulb was nearing its end, but I'm still seeing it with the new bulb.

Any ideas why I'm seeing this issue?

Thanks!

Optoma HD20 Possible Lamp Failure ???

My 4 year old HD20 has put 1200 hours. Now the lamp fail light goes solid red after I watch for about 2 to 3 mins. Screen goes blank. I called optoma tech support. She said main board might need replacement. Part will cast $359, labor $100, shipping is $25.
Do you alll think the bulb has gone bad or main board need replacement. I can get bulb for $100. Any suggestions what could have gone wrong.

Optoma HD20 Problem with Black Snow in Red Areas.

I hope I am posting in the correct forum here...

I have an Optoma HD20 for about 4 years and I LOVE it! Only problem is that recently (within the past 3-4 months), after about an hour or two of the projector operating, any area of the picture that has red (not orange, not pink, but RED) develops little black dots that randomly flicker on and off. There is no particular pattern. It looks more or less like snow, but with only large black spots. If I turn off the projector and come back in a few hours, the problem goes away. It seems to be related the projector heating up.

It appears on 720p or 1080i. I had to change out the color wheel once because it shattered, but I managed to get the colors back into the correct hue after going into the service mode. Also, recently, I tried the "burn-in mode" of the service mode where it goes from red to blue to green to white to black (or some pattern thereof) and let it run for 12 hours. The red is always fine - no black snow.

I am going through a receiver, but after the symptoms appear, I have tried going directly to the projector - problem still exists. It make no difference if I am running from the Tivo, Blu-Ray player, or XBox.

I am using RedMere technology cables, going through 40 feet of cable up through the wall, into the attic/ceiling and then to the projector through an outlet plate coupler. This issue did NOT start when i started using the RedMere cable, so I do not think they are related, but who knows?

At this point, I am weary of purchasing another expensive HDMI cable just to run from the receiver to the projector simply due to cost, but I may have to do so, just to rule out the cables.

The room does get a little warm after a while, but that is just the nature of the heat from the projector. I do have a ceiling fan in the room that is always on, so I know the heat is evenly distributed about the room and not just focused at the projector area.

Has anyone else run into this issue? I have the stock firmware installed (I purchased the unit right after it came on the market).

Thanks in advance for any suggestions.

Hi,
does anyone know about the problem I am currently experiencing with the brighter upper right corner? The attached image can give a better impression on the problem.

My guess is that you have replaced the bulb at some point and the bulb is not a true OEM bulb and OEM housing replacement. Brightness uniformity is based on the light source and light path. The light path is pretty stable and static, which means its most likely the light source. Which is the bulb and bulb housing. Not sure how to test this theory without replacing the bulb housing which isn't cheap for the OEM unit.

I haven't heard of this one. If it is heat, have you tried setting the PJ to High Altitude (high fan) mode and bulb on Eco (low) mode? Also, are you using the original bulb or has it been replaced? If it has been replaced and you used a cheap bulb, sometimes there is no UV filter and extra heat.

It's really sad to see people with ruined projectors from these cheap bulbs. I'm glad I got mine from Provantage (they have the best price). My thinking is that most of the time the replica bulbs might be ok. but not for this projector. When my second bulb is out, I think I will get the newer 3D version. I think 4K will still be too expensive until a few more years. I won't spend more than $800 on a projector cause they can totally die on you at any time as we can see and it's just down to how much you can afford to loose. But I'd spend $1200 on a 4K 3D projector. We will get there, but not for a while.

Are you capable of independent thought, or do you need the government and mass media to do that for you?

It is sad that the HD20 (especially the newer version with plastic front lens) is so sensitive to heat. Though I personally would always use the true OEM bulb with any projector since it's not worth the hassle of possible issues just to save $100-150. But it is tempting.

4K would be awesome. But the last time I looked there was only 1 home level projector at 4K, the super expensive Sony for $25,000. Yes, you read that right, $25k! So out of the budget for me. Can't wait to see $4k drop below $2k. Honestly I don't see why it's taking so long. If DLP mirror density is an issue, just make the DMD chip larger and I can't imagine that would cost a ton more. Seems they could hit the $2k mark now and just have a larger unit and then shrink the unit over time. Still the biggest issue is 4K content and 4K distribution. Won't fit on a Blu-ray disc.

UPDATE: Looks like the Sony 4K projector I was talking about is now around $14K and no longer a current model. Still too expensive.

Not sure how to test this theory without replacing the bulb housing which isn't cheap for the OEM unit.
I suspected the lamp ... but the lamp had never been changed ... I will have a look at the lamp housing ... aliexpress
Thanks for the quick response xenon2000.

btw. the price on the 4k projectors just went down to less than $9k cheers

It'll get there. I don't think they should have trouble fitting it on a dual layer blue ray. Thats. 50 gigs. There was no real need for blue ray, i have several 1080p rips that fit on a 4.7 gig dvdr. I know there are more advantages to having more memory, but if they can do that in 4.7g then they should be able to do something with 50 gigs. I don't want another format. Data sizes are getting huge in everything. Just got my son a 500gig xbox one and the hd is already almost full. Just ridiculous.

It is possible, using higher compression for both video and audio. But if we want the quality of 4K video and high number of audio channels like 4K movie theaters, a 50 GB BD is not enough. If we are ok with streaming 4K content like Amazon Prime, then BD will work. At this point I mainly want a native 4K projector so the SDE is gone at huge 200" and higher screen sizes. Even at 125" my 1080p image has some SDE when I am sitting close enough to have the screen cover my entire vision. I would like to improve on that. Even if the 1080p source was upconverted to 4K, it would be nice to have the actual pixels be smaller on the screen.

For my PC gaming, I don't have a card that would run at 4K, but I would still want the PJ to upconvert to 4K. Besides, we need more displays at 4K to give hollywood a bigger reason to push 4K distribution. They already have the content for 4K theaters, so why not sell it at 4K at retail?

And yeah, 4K will definite happen.

I just did a google search. Currently 4K movies are 225+ GB for 2 hours. And Sony is stating they would like to provide a 4K download service with 4K movies being 100+ GB. Remember that 4K is actually slightly more than 4x that of 1080p. So even if they get the file size down to 100 GB, that is still more compressed than BD and twice the space is needed. And still doesn't cover the extras. Which for 4K, I would be happy with supplemental discs if I can buy a Disc with 4K movies and at least 7.1 audio or better yet, Dolby Atmos and other high speaker count formats.

Commercial theaters really need 8K as I can easily see the pixels of 4K movie theaters at the front of the middle row. When used on the super huge screens. So there is room to increase to 8K for commercial theaters.

Hopefully they can come up with a good 4K BD based format to push 4K displays while we wait for a high capacity storage medium.
