Why no large 3440x1440 monitors? And also running 21:9 on a 4k TV?

I'm in the begining stages of setting up a sim racing rig but really struggling to find the right monitor. What I really want is a 38" minimum (bigger the better) 3440x1440 Ultrawide monitor but the closest ones I can find are:

38" 3840x1600 (Ultrawide+)
49" 5120x1440 (Super Ultrawide)

I currently have a 34" 3440x1440 on a desk which I use for everything including sim racing currently and the 21:9 aspect ratio (yes I know it's not exactly 21:9 but that's what we are calling it) is perfect for everything I do but it's just too small to mount on a sim racing rig.

3440x1440 = 4,953,600 pixels which is perfect for my 3090 because I can run everything at Ultra graphics settings at 100Hz. The two monitor options above are 6,144,000 pixles and 7,372,800 pixels respectively which to run at decent graphics settings I'd have to dial some graphics settings back and probably drop down to 75Hz or something which isn't exactly what I want.

I don't want triples and I don't want a single 16:9 monitor (aka large TV), so why isn't there any large 3440x1440 monitors out there? I've been waiting for years but no one ever makes one so there must be a good reason.

My other slightly out of the box option is a big 4K TV setup with a custom resolution set in Nvidia Control Panel to achieve the 21:9 aspect ratio that suits sim racing, yes I'd have black bars top and bottom but I race in total darkness anyway so that wouldn't be an issue, is that even possibe with a TV? If so, would I still end up having to render the black bars so essentially running 4k with its 8,294,400 pixels? Because again that wouln't be ideal for me to have to run that.

From a quick Google search on the topic of running 21:9 on a 4K TV lots of people post in threads saying "whats the point, why cut off the top and bottom" but they clearly don't get how 21:9 works and that it's scaled from the vertical size of the screen so you are not cutting off the top and bottom, instead you are actually gaining more on each side. I obviously don't have to tell you lot that but I wanted to "In before" those types of comments start appearing

I guess there is just a perception of very little demand for this size and format, certainly I would want 38" 3840x1600 myself as the dot pitch suites me better for desktop work ...use on sim rig is quite specific I think, I think the TV approach with custom resolution may give you the most immersive experience. You can run a custom resolution on a TV and no you wont be rendering the unused pixels, as you would create a custom resolution in the OS, you can do it with Nvidia and AMD control pannels and then output that. What you will find though is with a traditional VA TV it will still light the unused pixels so in a darkened room you will see glow in the corners and possibly along the top and bottom edges ...if however, you use an OLED it will not light the unused pixels so it will stay pure black and would be MUCH better in my opinion. I do this myself from time to time with a 55 inch OLED only I use 3840x1600, as you say for the ultrawide benefit to FOV, which as you also point out a lot of people don't seem to 'understand'. If you use an AMD card with an LG OLED though you will need to alter the timing to 'CVT - Reduced Blanking' I have found.

Thank you for the info
