Sure, you can ask!
I play 4:3 games exclusively. And most of those are, technically, 3:4 (vertically-oriented) games.
3:4 games on a 16:9 screen leaves a -huge- amount of blank space on the left and right. Accurate bezel artwork wouldn't fill it properly, and I tend to find that stuff a distraction anyway. So I feel like a vertically mounted 43" HD screen will give me the size I want with the minimum amount of wasted (visible) display space.
