another thing to consider is to keep the emission of the screen low and looking bright, but add another LIGHT outside the screen to cast some light onto the surroundings. In LW Native we would do this with the image sequence attached to the light so the colors and movement would be in the light as well. Not sure if that would be possible in Octane, but as mentioned your looking for a bit of a fake look and so get artistic I guess...Good luck.

You are right but the problem is that you are trying to make impossible image with unbiased renderer, I think you need to do that afterwards in Photoshop or similar, Octane does it as it works in real world where you need huge power to overdrive sun light and such image would look like it looks in Octane when you ramp up the power i.e. the brightness overloads the image colors so changing them

Octane is just too realistic for this goal

Can you guys please post/share your texture emission parameters? I'm having trouble dialing in the light. I'm trying to light the room with the screen while also showing the image texture, but it keeps blowing out the image. The example with the green ball in front of the tv is what I'm going for, but my image keeps getting blown out. Please help.

Another option is that you could have a light infront of the screen that is not visible to camera and with it's opacity at 0, note that the light must be a sheet of geometry with an emissive texture on it and be just in front of the actual screen, a standard octane light might not work so well for you. The actual screen then could have it's 'cast illumination' setting turned off.

This would allow you an extremely tight control on the lighting and the result of the screen as independent materials, you could also mix the diffuse material with a glossy material (with the diffuse material being dominant of course). This would allow you to have a slight sheen on the screen and give you a much more accurate LCD/LED result.

It really depends on how you want to handle the brightness and vividness of the screen image.

did you add the texture to the diffuse material as well?
