  1. Contrast Ratio

    Home Theater Projectors
    How concerned about contrast ratio should I really be? I read an article that manufactures don't truly know what the contrast ratio is and consumers should be more concerned about lumens than the contrast ratio. Would love to hear all of your thoughts ?
  2. What are the limits to the perception of contrast?

    DIY Screens
    First, how many just-noticeably-different shades of gray do video-players need to produce to correctly/accurately display content? 255? 50,000? 16million? ..It looks like a majority of HD and SD content is 8bit and can display 256 shades. 10Bit content can show around 1000shades while 12bits can...
  3. setting contrast on a digital (Sony VPL-VW1000ES) projector

    Video Calibration
    Guys, I just bought a Sony VPL-VW1000 projector. The first thing I always do when I calibrate my projector is make sure the contrast and brightness are set correctly. I always do this by putting up a black clipping test pattern for the brightness and white clipping pattern for the contrast...
  4. REW in High Contrast mode

    REW Forum
    I'm a newbie. I just installed REW v5. (I'm really excited to have found such a powerful tool for such a great price!) I'm going to hold off asking lots of questions until I read the manual and forum posts, but I'm sure I'll have plenty of questions... But for my first "constructive...
  5. Anyone does contrast comparisons?

    DIY Screens
    I assume this must have been done. What I mean is, measure the on/off (white/black) contrast from the projector itself with a lightmeter, and then compare it to the measured contrast from the screen with various paints/materials, so we can see how much of the contrast the projector is capable...
  6. contrast

    Home Theater Projectors
    I want to start this off by saying I am not trying to start confrontation and most of my questions are probably very subjective. I have been trying to figure it out on my own but I thought I might just as well ask my friends here. My question is- Why are people so drawn to on/off contrast...

  9. Draper high contrast grey?

    Manufactured Screens
    Does anyone have experience with this material? I have an Epson 8350 in the living room. I'm happy with the performance, but since it's plenty bright, I thought a grey screen might improve contrast and help with light bouncing back to the screen.

  12. 1st attempt with painted white screen - contrast drops on bright scenes

    DIY Screens
    Hi all, I'm not only new to this forum, but also new to the home theater scene. After a lot of research and reading on forums I decided to buy the Epson 8350. I also want to make (paint) my own screen. Our HT is in our basement and 95% of the time the room will be completely dark when watching...
  13. What meter to get for contrast measurement?

    DIY Screen Development and Testing
    This question pertains more to screen testing in general, but I am wondering what the best equipment would be to get for measuring contrast? I can easily put together an ansi contrast pattern, but I have no idea when it comes to the meter to use. This will be for measuring the amount of...

  16. Contrast discussion

    DIY Screen Development and Testing
    As I came across a fellow Swedish screen DIY guy trying to find the solution to front projection in medium to high ambient light I started to reflect (no pun intended) on the measuring you guys do at HTS. Is it possible to define an ambient level of light and then measure the ratio between the...

    DIY Screens
    Mech, Bill, Don,........... In your trials of testing all of these DIY mixes, from this forum and elsewhere, have you done any emmisive readings off the screen to check for contrast ratio? Can it be done with any accuracy with your Eye1Pro? I'm wondering if doing something like that would put...
  18. HL-R6167W - Green outline when low contrast

    Samsung
    Maybe someone can assist. When there is a low contrast scene and/or dark scenes my hl-r6167 will outline the images with a blurry green outline. With normal good contrast scenes there are no problems. I had the color wheel assembly replaced about 2 years ago and the problem has been...
  19. DIYTheater.com No Contrast screen paint kit

    General Screen Discussion
    Any ways, as I have finally settled on my screen size, I began the application. I had previously put down four coats of Killz2 to cover up the red paint. I used that for a few weeks to be sure I was OK with the size and everything. Yesterday, I put two coats of the included primer just to be...
  20. Understanding Contrast Ratios in Video Display Devices

    Video Calibration
    Introduction When we shop for a projector, one of the specifications that we really want to be aware of is the Contrast Ratio (CR). In general, we know that it is the relationship between the black and white levels that a projector can show. Well, it is a little more complicated than that, and...
