Maganda na sya. Malaki talaga improvement kapag dark neutral color ang paligid ng screen. Congrats!
The worst is white or cream kasi namamatay ang contrast ratio. Washed out ang itsura. Flat. 2-dimensional.
Next worst is when the walls are not neutral color, say red or blue. Baka maganda sya tingnan when the lights are on but once, umandar na pj, the colors on the screen are affected by the colors of the walls.
Ano plano mo sa acoustic treatment?
