618活动买了台明基EW3270U，送了条山泽的HDMI 2.0。显示器本身自带一条mDP转DP和一条Type C，只能用来插笔记本。
然后我就觉得不对，因为我印象里HDMI 2.0跟G-SYNC Compatible的兼容性是不大好的。于是就随便搜了几个2K 144Hz显示器，宏基XV272U P和惠普(HP)暗影精灵X27I也是只有HDMI，AOC CQ27G2只有DP，LG 27GL850两个都有。至少在我检索的范围内，一半左右的显示器都不带DP。
另外这是Nvidia和AMD对FreeSync的说明：
Nvidia：
NVIDIA GeForce GTX 10 series (Pascal) and higher GPUs supports VESA Adaptive-Sync variable refresh rate over the DisplayPort 1.2a standard. If you have a G-SYNC Compatible monitor, VRR features will be enabled automatically giving you an improved experience in games. If your monitor isn’t listed, you can enable the tech manually from the NVIDIA Control Panel. It may work, it may work partly, or it may not work at all. To give it a try:
1. Connect the monitor to your GeForce RTX 20-Series or GeForce GTX 10-Series graphics card using a DisplayPort cable
2. Enable the Variable Refresh Rate functionality of your display by using the monitor's controls and On-Screen Display
3. Open the NVIDIA Control Panel from the bottom right of Windows
4. Expand the "Display" section
5. Click on “Set up G-SYNC”
6. Tick the “Enable G-SYNC, G-SYNC Compatible” box
7. Tick the “Enable settings for the selected display model” box
8. Click “Apply” on the bottom right
9. If the above isn't available, or isn't working, you may need to go to "Manage 3D Settings", click the "Global" tab, scroll down to "Monitor Technology", select "G-SYNC Compatible" in the drop down, and then click "Apply"
10. Additionally, you may need to go to "Change Resolution" on the left nav and apply a higher refresh rate, or different resolution
NVIDA GeForce GTX 16 series/RTX 20 series (Turing) and higher will support variable refresh rate over HDMI on displays which support this feature over HDMI 2.1. For the best gaming experience, we recommend a G-SYNC Compatible display. To enable this:
1. Connect your TV via HDMI to your GeForce RTX or GeForce GTX 16-Series or higher GPU
2. Enable the HDMI 2.1 Variable Refresh Rate functionality of your TV/display through it's own internal settings
3. Open the NVIDIA Control Panel by right clicking your desktop > NVIDIA Control Panel
4. On the left nav, select Display > Set up G-SYNC
5. Enable G-SYNC, and click Apply on the bottom right of the window
If you don’t own a G-SYNC Compatible TV, but do own a display or TV that only supports variable refresh rates via HDMI 2.1, you can try enabling G-SYNC as detailed above. As these displays and TVs have yet to through our comprehensive validation process, we can’t guarantee variable refresh rates will work, or work without issues.
AMD：
AMD FreeSync(游戏智能显示)技术可以通过 HDMI® 启用吗？
是，FreeSync(游戏智能显示)技术自问世以来就一直支持 HDMI。 在发布 HDMI 2.1 和采用 HDMI VRR 前，许多经过 FreeSync(游戏智能显示)认证的显示器就已经支持 HDMI 可变刷新率技术。 购买支持 HDMI FreeSync(游戏智能显示)的 FreeSync 认证显示器，即使显示器不支持 HDMI 2.1，也可以立即获得可变刷新率的优势。
简单来说，G-SYNC Compatible(N卡)需要10系以上的显卡 + DP 1.2，或者16系以上 + HDMI 2.1。而FreeSync(A卡)只要分辨率+刷新率+色深不是特别高，HDMI 2.0是够用的。
