What vendors make good dumb TVs or big monitors?

The EMMC on my PC-TV finally broke down and I'd like to replace it with something that doesn't run an OS or will predictably fail with a countdown. But dumb TVs are hard to come by and monitors come at a premium at that size. I want to run a PC (DP/HDMI) and an SBC (HDMI) with it. I also have an S2 satellite cable, but that's secondary. I'd like to have ~43", 16:9, 4K but without an embedded smart-hub, ideally running of eeprom-firmware, or just anything independent of write-cycles. But I can't find any good options online. Are there companies for this. Comments and recommendations welcome.

Edit: I'm EU, hence the DVB-S2 cable. Scepter would be great, but doesn't run on EU power.

Edit: I've pretty much settled on a philips 439P1/00. I'll give it another day, but it seems good. The PC over DP is my main focus and I can connect my own SBC for streaming. It lacks freesync but has adaptive sync and basic HDR. Being an office-monitor, it has no smarts and at ~600 bucks with consumer warranty and support it fits what I'm asking for well. Industry-signage wasn't really an option.
