Because one of the monitors which was flickering was not flickering on an amd card once the user edited the FreeSync range. On an amd card, the LG monitor flickers when the FreeSync range is 50-144 which is default. It doesn’t flicker when chnaged to 30-14. So nvidia when showcasing that monitor didn’t even try anything to get it to work, so I suspect they aren’t going to wholeheartedly support all FreeSync monitors so they could enforce that 2.4:1 requirement on non validated monitors to weed out crap. Some monitors have as low a range as 48-75. That’s just garbage honestly. FreeSync always needed research. The majority monitors are crap. If I try to find a FreeSync monitor with a range of 30-144 along with proper blur reduction and LFC support and IPS panel, that eliminates 95% FreeSync monitors from the market and you have to search hard to find one. G-Sync has spoilt me honestly. Now that I look at the FreeSync market for budget 144hz gaming monitors its hard to find a replacement for the S2716DG at the sub 400 price point I got it for.
