广测传感器厂官网
作者：yhgg
本次带来微星的一款显示器——微星 MSI Optix MPG321UR-QD，这款显示器采用32英寸的友达原生10bit IPS面板，超窄边框设计感官更精致小巧一些，分辨率最大3840x2160，最高支持144Hz（DP）的刷新率，低于5ms的GTG响应时间和1ms的MPRT响应时间，拥有8个背光分区支持HDR600，同时搭载Quantum Dot量子点技术拥有97%DCI-P3色域，还自带KVM 3.0功能，看参数指标4K高刷+广色域可以说游戏、生产力两不误，后面会进行一系列简单测试。下面一起进入开箱环节。
首先是显示器正面和背面整体展示。
来自官网的具体性能参数指标。
附件方面非常丰富，尤其是线材种类很多，DP1.4、HDMI2.1、Type-C、3.5mm音频线各一条，3条USB-B to A数据线，还有一个鼠标理线夹以及固定螺丝若干。
首先来看显示器支柱，整体主色为黑色，中心为钢琴烤漆亮面，其他区域为磨砂质感材质，两侧设计了斜纹刻线。
中央MSI Gaming金色标识。
连接座背面仿铝合金金属拉丝工艺处理。
来看支柱另一侧，前面是VESA显示器连接座。
后方是连接座双滑轨。
支柱底部为铸铝合金材质，稳固牢靠。
底座为矩形，上面黑色盖板富有凸起的集合棱线增添质感。
中后方是支柱安装孔位，可以看到孔内壁为铸铝合金材质。
底座尾部的设计有点像兰博基尼雷文顿，给人速度感。
来看底座底部，底座为金属材质，很重，四周标配了六个防滑脚垫。
底座与支柱通过免工具螺丝固定。
显示器支架的底座和支柱合体成功。
支架与显示器的连接构件，可上下、俯仰滑动。
来到显示器支架，这里拥有一个水平开口的理线口，可以让玩家整理线材。
来看显示面板部分，通体黑色，32英寸的对角线尺寸。
窄边框涉及，沉浸式视觉体验应该不错。
左侧设置有一枚Macro Key自定义宏按键，旁边两个小孔可以安装鼠标理线夹。
面板下方边框中心印有黑色MSI Logo，左右两侧小孔为麦克风中间类似摄像头设计的是自动亮度光线传感器。
屏幕右下方的白色方形按钮是电源开关，同时也是电源指示灯。这一次也设计了理线夹，两侧都设计估计是照顾左右鼠标惯用手的玩家。
理线夹免工具安装，为弹簧加橡胶制成，支撑力不错。
面板背面采用不规则几何设计，工艺复杂，分别采用类碳纤维纹理、钢琴烤漆镜面、类铝合金金属拉丝以及磨砂处理，左侧贴有MSI龙盾金色LOGO，左侧下方还有一个五轴控制摇杆也为金色，用于调用屏幕菜单功能，用户也可以根据自己的习惯和喜好对OSD按键的四个方向进行自定义功能设置。
接口方面就太豪华了：3个USB2.0 Type-B接口、2个HDMI视频接口、1个DP视频接口、1个USB2.0 Type-C接口、4个USB2.0 Type-A接口和1个3.5mm的音频接口，同时这款显示器采用了内置电源设计，免去外置电源适配器剩下空间。
左侧设计有Kingston防盗锁孔。
显示器侧面也设置了接口，为2x USB2.0 Type A，一个3.5mm麦克风输入，一个3.5mm耳机输出，方便用户随手使用。
通风散热格栅既是装饰也能强化内部散热。
背板中上部带有RGB灯条，为显示器背面营造灯效氛围，同时可以自定义颜色和关闭。
灯效开启的状态，默认为绿色。
顶部密集的散热通风格栅为显示器疏散内部热量。
左侧面的阴刻MSI设计制造标识。
将支架和面板组装，仅需要两颗螺丝锁紧即可装好。
背面。
整机正面升降高度展示，滑轨总行程0-100mm，首先是正面升到最高高度和滑轨降到最低高度。
背面升降展示。
侧面最高高度。侧面最低高度。
仰角最大角度20。俯角最大角度5。
左右扭头角度展示，向左侧最大30旋转角度。向右侧同样30。
下面来看OSD菜单展示。首先是G.L菜单，功能包括自动亮度调节、自动色温调节、麦克风AI智能降噪（这款显示器集成了ALC 4050音频解码芯片）、KVM 3.0、狙击镜放大、射击准星等游戏辅助功能。
游戏菜单可以根据玩家的游戏种类选择最适合的屏幕模式，像FPS这种射击类游戏就需要依赖高刷新率带来良好的效果。
专业模式包括内置色彩模式，生产力用户估计会经常操作这个菜单包含SRGB、ARGB、P3等色域选项，另外还有护眼减蓝光等其他功能。
图像菜单可以更细致的调节显示器亮度、对比度、清晰度以及色温等。
输入源菜单支持信号自动切换与扫描，更换数据源无需手动再调。
画中画及并排画面功能菜单。
导航键可以四个方向自定义宏，觉得默认不科学不习惯可以自己调成适合自己的快捷功能。
设置菜单可以设置语言、OSD菜单外观、背板RGB灯开关等。
这款显示器除了常规用OSD菜单调节，还可以通过连接USB线和主机，下载安装GamingOSD软件来设置显示器的各项功能，甚至键盘鼠标参数都可以复核调节。
G.L辅助瞄准功能展示，提供了多种准星模式供玩家选择，为射击游戏提供瞄准辅助。
Optix狙击镜功能展示，开启之后屏幕中心会出现放大的画框，瞄准的画面部分会被放大显示，放大倍率可调，手慢没来得及开倍镜的玩家有福了。
二、性能测试。
微星Optix MPG321UR-QD显示器DP接口支持4K分辨率、144Hz刷新率，支持Adaptive-Sync防撕裂功能，也通过了NVIDIA的G-Sync兼容模式认证。
登录Blur Busters UFO Motion Tests网站进行刷新率测试，144Hz刷新率下，使用最快速模式，飞碟运行更顺畅平滑无卡顿。
屏幕测试环节引入红蜘蛛SpyderX Elite，显示器恢复出厂设置，首先是默认色温计测量，出厂调教的显示器亮度为189.65cd/,色温为7045K，稍稍偏冷一点。
通过软件显示器分析进行进行以下几个测试看看屏幕表现，显示器均为出厂默认设置。首先是屏幕色域覆盖了100%的sRGB、100%的AdobeRGB以及94%的DCI-P3。这在主打游戏的显示器中这么宽的色域是不多见的。
色调响应与2.2伽马标准曲线高度重合，没有偏差，色温从25%开始维持在7000K左右，对于生产力方面出厂略冷一点，后期可以校色调整，不过对于游戏来说稍稍偏冷是非常合适的。
亮度与对比度测试，这款分区背光的显示器默认出厂亮度最大可以达到890：1。
在色彩亮度均匀性测试中，象限7、9、1、3、4最接近D65，最大差异为2.1，屏幕整体表现出色。
亮度均匀性测试中，象限5的差异值最小为0，差异最大的是象限4，差异值为17%。
48色色彩精确度测试中，平均值只有0.71，最大值为1.23，最小值为0.17，表现很好，能够充分还原真实色彩。
三、屏摄环节。
以下屏摄照片均采用60mm焦段拍摄，显示器色彩模式为初始用户模式，样张选用体现彩色、饱和度、对比度等的图片，分几何、植物花卉、动物、人像、风景等展示。为真实还原色彩表现，仅缩小分辨率无其他后期修改。PS：空间有限加上边框过窄，上边框和左右边框都齐边框拍摄无任何裁切。
总结：
4K分辨率、144Hz刷新率和1ms极速响应，支持NVIDIA的G-Sync Compatible，作为外设中最重要的显示器，搭载Quantum Dot量子点技术采用分区背光方案的微星OPTIX MPG321UR-QD的表现是完全满足的，同时准确的色彩表现广色域带来的生产力潜能也能一专多能，作为体验来说，个人觉得一款色彩精准的顶级显示器的分量是和显卡同等重要的。另外个人觉得遗憾的，一是所有USB都是2.0的，升级3.0实用性更好，哪怕屏幕侧面接口两个给到也好，二是这款显示器不支持垂直旋转，有竖屏需求的还是上爱格升吧。
以上，仅代表个人观点，仅供参考，谢谢观看！
