- The window in the room will be covered with a blackout curtains. Do you think its necessary to add curtain behind the sofa ?
- I am not be painting the walls in dark black.
Wall reflections will affect black/contrast for all projectors, including low contrast ones.
Doesn't have to be black paint, some dark paint will do.
What type of games? 4K DLP's have varying lag, from 40ms upwards. The Epson's have mid 20's.
This room does not have the distance for ALR screens to be used. Even the most expensive would likely artifact.
On the 263cm wall the biggest screen that can be installed is 118.8" (16:9).
On the 322cm wall the biggest screen can be 145.5".
Both of these without a border. If the border is ~2", substract ~4". So ~115" and ~141".
Estimated viewing distance with the ~115" is ~272cm/~9'.
Estimated distance for the ~141" is ~213cm/~7'.
The way to determine the right screen size is to use the projector on the wall for a few weeks.
A very general ratio is 10-12" for every foot in distance. For 9' it would be from 90 to 108". For 7' it's from 70" to 84".
The TW9400 is 45cm long. With ~10cm at the cables at the back, in the setup with 322cm wall to wall, the remaining distance is 267cm. Which results in a screen no larger than 88".
A UST projector and a UST ALR screen could work. The Optoma and LG mentioned above will have good black level. UST ALR's are best at rejecting light from above, less from anywhere else. They're both DLP.
Painting the room in a dark color/shade will still improve things with an UST ALR screen.
Front projection models with lower throw ratio with good blacks don't exist. The Benq W2700 (HT3550 in the US) has worse black level than both UST's mentioned above.
