Don't buy a cheap TV for programming if you're not constrained by money. You can get 40" monitors for a bit more, and you won't need to fight the firmware and also you can get a better panel. Also, PWM is worse if you're sitting close. Uniformity of backlight (bleed) also matters.
Currently the display you want to get around 40" is the Philips BDM4037UW, which has no PWM, relatively low input lag and backlight bleed is low.
There are some cheap 43" 4K monitors (Philips and LG), but they're lower quality e.g. LGs have PWM.
