If you don't need something much larger than 43 inches, and you are cool with wide monitors, there are a couple ones that seem good:

- Samsung 40 inch Odyssey G7 (G75F) Series WUHD Curved Gaming Monitor (https://www.amazon.com/Samsung-Odyssey-Curved-Gaming-Monitor...) -- $699.99

- Acer Nitro 49 inch DQHD 5120x1440 Curved 120Hz Office Monitor (https://www.amazon.com/Acer-Nitro-Gaming-Monitor-UltraWide/d...) -- $549.99

- Acer DM431K A 43 inch Class 4K UHD LED Monitor - 16:9 (https://www.amazon.com/acer-DM431K-Class-UHD-Monitor/dp/B0F3...)-- $334.20

- LG 37G800A-B 37 inch Ultragear 4K UHD (3840 x 2160) Curved Gaming Monitor, 165Hz, 1ms (https://www.amazon.com/gp/product/B0FS3LV3WG) -- $598

- INNOCN 40C1R Ultrawide Monitor 40 inch WQHD 3440 x 1440p 144Hz (https://www.amazon.com/INNOCN-Ultrawide-Monitor-FreeSync-Pre...) -- $479.99

I have a 43" Philips Ambilight (43PUS8510, 4K QLED). It's not a dumb TV per se, but you don't have to use any of the smart features, and - most important - you don't have to connect it to a network.
