Hi Guys,

Mechman/wbassett/Harpmaker !!! :wave:

It has been a while… :innocent: :eek:lddude:

Finally after almost 4 years of using happly Optoma HD65 (1600 lumens) on BW 110” screen :clap: :T I pulled the trigger on a new projector Optoma HD25e (1080P/3D). Overall HD25e is very good projector, quiet, nice resolution, bright, nice 2d and surprising good 3d. The only problem (I’m might be too picky) it suffers from soft/blury/out-of-focus corners upper-left and lower-right. (it seems to be optic lens related, and Optoma is aware of it). It is only visible when using HTPCs’ win7 desktop, during movies/games you cannot see it.

After using your excellent BW paint (n8 and original) for almost 4 years now with HD65. I think it might be a time to change it to something less reflective?, to tone down brightness and help blacks.

According to specs HD25e outputs 2800 lumens (I’m sure it is a marketing schema LOL), but it is much, much brighter than HD65 projector.
It almost feels like having a light canon comparing to HD65.

I’m throwing from 13’ onto 110” DIY (4” frame wrapped in black velvet). Please see my old setup (few things changed since than, new speakers and treadmill and no more CRT tv LOL). The wall colors are the same, and ceiling is still white (never got WAF to paint it with a darker color).



With the current setup I find the picture tad too bright in 2D for my likings, there is less problem in 3D with help from shaded 3D glasses.

Do you guys think BW is still best DIY paint for my setup or should I try something else to tone down the brightness and bring out better blacks? :dontknow:

Is Glidden Veil in a flat base (quart) a way to go?

Please do not forget I cannot spray-paint (no tools or skill for it :sweat:). Easy to roll paint would be my preference. I should have access to all common paint stores where I live (Ottawa, Canada).

Any help would be very much appreciated.

Thank you. :bigsmile:

Glad to see you back!!!

If you are using the original N7.5 BW™ then going with a flat finish paint color-matched to Glidden 'Veil' would drop the brightness of your image a bit. To go darker yet get a flat finish paint color-matched to Glidden 'Dover Grey' with is about N7.

Thank you so much.... :clap:

Yes I was using N7.5 BW, excellent paint but with the new projector I find it a tad too bright. However it served me well for the last 4 years. I'm leaning toward 'Dover Grey' N7, do you think it would be good ok for 3D? I have fully light controlled basement and I watch TV mostly at night.

How many coats do I need to cover well BW? what roller should I use (1/4 inch roller?)? and how long should I wait between coats? Would a quart do it?

So when I go to local Canadian Lowe's I should ask for Valspar Ultra Premium Latex enamel (is this correct?) tinted Dover Grey from the Glidden Master Palette?

I'm sorry for for all this questions but is has been a while... :whistling: :innocent:

Thanks... :T

Hello clark17!!

Planning doing a calibration on a 25 tonight. If you like, i can upload the data for luminosity. However, you can start lowering the B.C. value (put it to 0 if possible). The B.C. on Optoma works somehow like a manual iris and i liked that a lot.

That would be great... :T

I'm currently using following settings from HD25 posted from another forums (someone calibrated it). Keep in mind I'm using HD25e with more efficiant bulb.

Brightness: 0 <-- to help high brightness I have it at -1, if I go lower I lose shadow detail
Contrast: -3 <-- i did bump this to -1/0
Sharpness: 9
Colour: 0
Tint: 0
Advanced

ECO lamp mode
brilliant color off <-- HD25e does not have off but 1 is the lowest, mabye 1 means it is off
Film gamma
dynamic black off
Noise Reduction off <-- Projector is quiet enough that I can manage low or high setting, however the difference IMHO is not worth it.
Colour Temperature Warm


white (grayscale):
Red: 1, Green: - 4, Blue: - 11

CMS (in order hue, saturation, brightness):

RED: 6, 0, 16
GREEN: 12, 1 - 3
BLUE: 17, 50 - 20
CYAN: 27, 16, 4
YELLOW - 16, -5, 5
MAGENTA: 27, 16, 4

The color temperature is now reduced to 6508K and a deltaE gap reduced to 0.6

hope my settings are correct here.

If anyone can help me to tell me what valspar type of paint to buy i would really apprciate. :dontknow:

I'm leaning toward "Dover Grey" tint. However I don't want 3D to suffer to much from having darker screen. Maybe switching to N7.5 paint without any refective particles (aka BW paint) would be good enough...hmmm... I guess I can always repaint it...

Thank you :bigsmile:

Nope...don't give too much credit on online calculators. It's a good place to start, but that's all. I 'll take some readings too for 3D using the glasses (if there are available) to see how much light is lost.

Which one should I buy?

Valspar Ultra Interior Base (flat)

~ or ~

Valspar Signature Colors Interior (matte)

Harpmaker you said somewhere you would go with the Signature series now?

thank you
If you can get Valspar Ultra in "Super Flat" finish then use that as it is the exact same gloss as the older Valspar Ultra Premium flat enamel; but if you can't then get the Valspar Signature in matte finish.

Yes, we are going more with Valspar Signature paints because Valspar was doing crazy things "upgrading" the Valspar Ultra Premium line. Different stores still have different type of paint from that upgrade. Also, people that roll their paint seem to prefer the way Signature goes on.

Thank you so much for your feedback. I will see what my local Canadian Lowe's offers. Would you guys want me to sent you a sample so you can measure it? Also based on the 'limted' specs on my projector? Which tint should I go with? I'm leaning toward darker Dover Grey, however I'm afraid I'm might lose too much brightness for 3D movies. Also someone pointed out I should wait before I repainted it because the bulb within first 400hrs will lose up to 40% of brightness. I remember reading somewhere you said with newer more powerful projectors there is less need for reflective additives (such as used in BW paint).

Please advise... I guess I could always repaint it... would quart be enough for 2-3 layers over BW?

thank you :D

ok... I'm super super confused about Lowe's/Valspar naming... :dontknow:

I was looking on Canadian Lowe's site and I found 2 types of Signature series in matte, which one should I buy?


Valspar Signature Colors Interior Base C Paint Primer


~or~

Valspar Signature Colors Interior Base #2 Paint + Primer


thanks...
Rather than explain the differences between those two paints, which would probably just confuse you more, all that matters is that you tell the Lowe's paintperson you want a can of Valspar Signature paint in matte finish and in the color you want. Your links were for two different Bases (among other things) and that is not something you normally tell the paintperson since what Base is used depends on the color of the paint you buy.

If you are worried about going too dark with 'Dover Grey' then go with 'Veil'. If you go lighter than 'Veil' you might as well stay with the N7.5 BW™.

Please advise... I guess I could always repaint it... would quart be enough for 2-3 layers over BW?

thank you :D
Valspar says a quart of Signature interior will cover 100 square feet and since your screen is 36 square feet you should be able to do it since you shouldn't need more than two coats.

Harpmaker thanks so much for all your help :). I should have your home address, I will double check my PMs.

I'll go with darker paint... worst case scenario I will repaint it again :).

Now I have to find some time to do it....

Last question how long do I need between coats? 2 hours to be safe?

I did PM Mech (if he is intrested) and Harpmaker to verify their home addresses. if anyone one else is intrested in receiving paint samples for reading, please sent me PM with your home address.

I'm planning to visit local Canadian Lowe's in the next week or so to get Valspar Signature paint in matte finish color-matched to Glidden 'Dover Grey" ~7N.

If you roll the paint on I suggest you go by the directions on the paint can. It is very important that the previous coat of rolled paint is dry before you roll on another one or it might actually be pulled up when you roll the next coat. Been there, done that... :gulp: and one of the reasons I prefer to spray. ;)

Hey Guys….

Samples to Mech and Harpmaker were send.

Overall the “VEIL” tint is pretty good. However due to my bright projector I might go for something tad darker (more N7-ish).

My roll job unfortunately look like it was sloppy or perhaps Valspar Signature is harder paint to roll than my previous rolling experience with BW mixture using Valspar Ultra premium flat enamel.
I can clearly see some rolling lines and some spots. I did 2 coats, 7 hours apart and I used ¼ roller.

Since Vlaspar Ultra premium is not available anymore, and I’m too happy with Valspar Signature how it rolled (or I should blame my poor rolling skills)… Should I try Valspar Ultra in flat, (since there is no “super flat”) ???

The roller marks/spots look bad during bright scenes and I have to fix it…

Any advice / help would be much appreciated.

Thanks so much in advance.
