White projector, black room

Sorry in advance if this is posted in the wrong forum. I have an Epson 6020UB that likely needs to be replaced . Looks like it will need a new optical block, engine, ow whatever it is called as one of the LCD panels is messed up. It will likely be cheaper to get a new projector (warranty, newer features,etc). So, looking into a new projector and wondering what it would be like having a white projector (6020 is black and fits the dark room decor nicely)? I'm often sitting in a chair watching TV where i'm actually behind the ceiling mounted projector so it is in my periphery but blends in nicely. Other seats in the room are basically inline with the projector so they would have much less periphery issues with a white projector.

Does anyone have a dark to black room, ceiling mounted white projector in their periphery and find it distracting, etc?

Thanks

Or just replace your projector with a black projector. Epson 6040/6050 would be a logical upgrade but of course JVC would be my choice as they are all black but understandable might be out of budget. I think the Epson 4040/4050 is also black but might be a down grade in contrast. All the white 4K DLP models would have worse contrast and most likely would need to be moved as they have limited lens shift.

Thought about replacing with a black projector but could save money by going white. The uncertainty of the distraction of the white projector in what is basically a black room is my concern. hmm........

I don’t know how distracting a white projector would be. You can try taping some white copy paper to yours and see what you think.

I have black ceiling and black projector and have never figured out why any HT projector is anything but black. Business projectors, gaming projectors and even media room projectors I can see someone wanting white I guess. Why they make HT projectors white is beyond me.

There have been a few threads about painting a projector black so I assume it is distracting to some.

Most projectors are white because most projector users have white ceilings in mixed use rooms and white projectors blend in better with white ceilings. The minority who do have black ceilings have black projector options available but fewer of them because that's the difference between majority and minority.

I wonder if "plastidip" would work? I worked on a refrigerator i painted with it that WAS an ungodly shade of green, it can be peeled right off without marring the surface, maybe test a small area first (like underneath which would be hidden from view)

Tried the white paper taped to projector. Ugh! See the pictures (excuse the crappy camera). Maybe i could get used to it to were eventually I won't notice it so much. I priced out the Optical engine and it's like $3k Canadian, and then the labour to replace the bad one. I could get an Epson refub 6030 for like 2K or an Epson refurb 5030 for like 1.2K. Wish I could find a refurb 6040 up here.

I believe in previous discussions it was mentioned that flat black vinyl car wrap might work on a projector as long as you don't block any cooling vents. Don't recall if anyone ever actually tried it and reported results.

Get a projector with a longer throw, so it's mounted behind the seating area

The room is the room, and to move the projector would mean electrical work, breaking into the ceiling to put some wood up there to hold the mount, etc. Not going for that.

This Is what I had to do as a black projector was simply out of my budget. If my BenQ 2050 was over my head I might have to take some serious corrective action, like using flat black painters tape and apply it to the underside.If you can't, just get a black projector. If I could have afforded one I would have bought one.

A hush box is another option and if the projector is located there in your vision there may be an additional advantage to knocking down some of the fan noise. Just keep in mind the projector needs adequate room to breath.

Thinking the hush box may be the answer. Did some measuring and figure 24"x24"x11" leaves about 3 inches of space on the sides, 3 inches of space at the rear, and about 1 inch at the bottom (there is already about 3 inches at the top where it connects to the mount. Do you think that's enough room to breath? Figure i needs the sides to be able to swing down or something so i can get to the lamp on the onside and electrical outlet, etc from the other side. Sadly, i cannot build this myself (i'm not so inclined with those type of skills and would likely hurt myself trying to constructs this so would need to find someone to build it. hmm.............

Depends on where the exit fans blow I would think. I have never built a hush box. Doing some searches should bring up a lot of information.

Hush boxes require very specific designs in order to provide adequate air flow for cooling. Some hush box designs even include their own fans to ensure proper air flow. Any hush box that in any way limits the flow of cooling air will likely lead to projector overheating and possible failure.

Not thinking of a real hush box that's fully enclosed and really built to keep things quiet. I'm thinking more of a box with an open front where the lens and openings are, with sides and back that can be open to access lamp, plugs, cables, etc. How much extra space do I need. My measurements in a previous post did leave a few extra inches. Here are pics of a white 5040. Isn't the front the area that needs the air flow?

Yes the air intake and filter is on one side in the front and the exhaust the other side. I would think having the front of the box 100% open as well as the back would help with sound and block any view of the projectors white exterior. Epson says the projector can be set on a table so there is no question the bottom needs no venting and all they say is do not place it where vents are blocked. It also has over temp protection .

I don’t know for certain but I would think the dimensions you mentioned would work.

A box like this could even have openings made into the sides if needed.

In the past I had one rather hot projector mounted pretty close to the ceiling and hot air would pool around it. I added a small computer fan (very quiet) a few inches away from the projector to just cause a little air movement and it did the trick.

An easy solution I used to cover my white projector screen cases with light absorbing black velours: https://www.amazon.com/D-C-Fix-D%C3%...r=8-2-fkmrnull


I'd use that same self-adhesive material for a white projector, provided surface areas are flat enough.

The projector's case gets hot even when sitting completely unobstructed in open air. Enclosing the projector in a box with just the front open will trap some of the heat radiating from the projector's case even if both the air intake and exhaust have a clear path at the open front. A properly designed hush box will provide cooling air passing over the projector's case in addition to having unobstructed air intake and exhaust for internally cooling the projector. For example, commercially available hush boxes enclosed on all but one side have provisions for cooling fans like the one pictured below:

In the OPs case I don’t even know I would call it a hush box, although it may help a little with sound.

He just wants to block the line of sight to the projector with a black surface. His box needs no front back or top, and as I mentioned above one or two computer fans powered off a wall wart transformer could be added if any clue of overheating came up. I have a cheap radio shack infrared temp measure gun. With something like that or even the hand test with and without would be good enough to see if temp was building. Test without the box and then test with. If the projector has a trigger output that could be used to start the computer fan.

Heat rises so he has that going for him and a true hush box will have sound insulation inside and that also will hold heat. Without it that should be better also.

A hushbox like 'Dave in Green' posted a picture of is more than i need. Bud is correct in that all i want to do is block the distracting white from view. The ceiling is low so going more than 11" from it people could accidentally hit it with their head. I figure to hang the box from chains. In reality it may not even be a box. Maybe 4 chains (2 for each side of the projector) attached to the ceiling with hooks. 11-12 inches of chain connected to a black painted piece of wood. Easy to take down if/when needed Black piece of wood blocks the white of the projector. Too bad i can't draw worth sxxx so I could see and show what this would look like.

I've had the paper attached to the projector for the past couple days. It's less distracting though still,,,,,,,,,,,,,,,,,,,,

In that case build a frame out of 4 pieces of wood the size you want and cover it with black velvet by wrapping it around and stapling it to the back/top side. Screw in 4 small eye screws one in each corner for your chains or what ever you hang it by. Black cord would work even.

It will be nice and light weight and nothing is quite as black as black velvet.

This should be a 1.5 on a 1-10 DIY scale.

Went from a box to a piece of wood hung 11" down. Now back to a box. Haha! I guess just one piece wasn't going to be enough as when i sit in the chair behind the projector I would still see the white of the back of the projector. So, 1 piece of wood for underneath 24", 1 for the back 11", and 2 for the side 11x24 or is t 24x11? Wrap the wood in black velvet? Wouldn't airflow be better, to whatever extent if painted black rather than using velvet?

What I was thinking about is a picture frame type shape. The center would be open except for the black velvet.

A solid piece of plywood or something will be a lot heavier than a light frame with cloth. Frame could be made out of 1x1 with a single screw holding each corner. Making it light you could even hang it from fishing line.

I don’t think heat will be an issue.

If you go to an art store I bet you could buy a blank artist canvas to use and just paint it black. Pick a size you like.

@squigly1 , the only reason I addressed the cooling issue is because it sounded as if you were planning a box that was only open at the front. As long as you are aware of the full implications of the cooling issue and design something that allows full air circulation you should be OK. Just remember that projectors are designed to be cooled by air freely flowing around the case in addition to air being draw through the case by the projector's internal fans.
