Yes! That's the best thing about a desktop PC, the Biiiiigly screens. I just upgraded my two main desktop machines with 40" 4K UHD HDR TVs. (Newegg BF sale for ~$220.) While simultaneously downgrading the PCs connected to their, to diminutive ASRock DeskMini mini-STX PCs. Thinking of selling off my gaming rigs. The DeskMinis are good enough for now.
If I really wanted to, I could get an i7-7700, 32GB of DDR4-2400, and a 1TB M.2 PCI-E 600p and a 2TB spinner, and fit them all in the DeskMini. About the only thing that won't fit is a GPU, and recently ASRock announced a "micro-STX" form-factor, that can take MXM GPUs. It's a bit bigger, but it also takes three M.2 SSDs!
Tech is still looking bright to me.
Although, I really thought that Intel would cut down their product line to only one or two chips, sell them directly to mobo makers to solder onto boards, and then sell "soft CPU DLC upgrades", that would "unlock" the features of the CPU on your mobo, using micro-code. (Want HyperThreading? $50. Want two more cores? $100. Want AVX/AVX2? $25. etc.)
