Yes, it is 100 Hz and not 144, I have reported the error for correction. By the way, my tip would be a 4K UHD 3840x2160 pixel device, because with it you simply see much more picture in the height.
Unfortunately, the devices with 120 Hz are already at 600 francs :( But if it didn't have to be so many hertz, I would recommend this Philips device:
Philips 288E2UAE/00 (3840 x 2160 Pixels, 28 ")
If you mean https://www.digitec.ch/comparison/13575123-13486204-17293845, these are actually different model variants (LC-M34-UWQHD-100-C-V2, LC-M34-UWQHD-144-C, LC-M34-UWQHD-144-C-V2) At the manufacturer, the corresponding product pages are also separate: https://www.lc-power.com/produkte/pc-monitore/curved-bildschirme/lc-m34-uwqhd-144-c/, https://www.lc-power.com/produkte/pc-monitore/curved-bildschirme/lc-m34-uwqhd-144-c-v2/, https://www.lc-power.com/produkte/pc-monitore/curved-bildschirme/lc-m34-uwqhd-100-c-v2/.
