我已经阅读了很多有关此类问题的文章,但仍无法解决。这是信息:
(电视) Sceptre E328BV-FMDC 32英寸1080p 60Hz LED高清电视
(图形卡) 2 x技嘉GV-N660OC-2GD GeForce GTX 660 2GB 192位GDDR5 PCI Express 3.0 x16 HDCP Ready SLI支持视频卡[运行SLI]
(作业系统) Windows 7
电视具有两个接口:HDMI和VGA(手册中说VGA支持1080p)。图形卡具有三个接口:HDMI,DVI-I和DVI-D。
我最初建立了HDMI连接。除文本外,其他所有内容看起来都很不错。最常见的示例是黑色文字在某些地方显示为蓝色或红色,蓝色带下划线的链接在某些地方为黑色。这些是最引人注目的示例,但是所有文本似乎都受到了影响。
我尝试关闭NVidia的超比例设置,并且在使用HDMI端口时,我的电视不允许逐点选择(其他电视为1:1或逐像素)。
然后,我购买了VGA至DVI-I电缆,文本看起来还不错,但其他所有内容绝对达不到1080p的质量。另外,在屏幕上水平方向上还存在一些细微但仍存在的静态Y线(即使在启用了V-Sync的情况下,它们在1080p上运行的游戏中也最为明显)。我读过某个地方,当您将VGA转换为1080p的DVI时会发生这种情况。
关于HDMI方法的两个有趣的事情:在Windows 7中关闭ClearType可以解决此问题,但是在此之后查看文本确实很糟糕,并且在NVidia控制面板中切换到自定义分辨率1080i似乎也可以解决此问题,但是随后其他所有东西的质量都非常差。
谁能解释这个问题的根源是什么,或者我将如何解决呢?我真的很想在这个上使用HDMI连接。
谢谢!
编辑:开始认为ClearType是这里的问题。找到此页:http : //msdn.microsoft.com/zh-cn/library/aa970267(v=vs.110).aspx
特别是Gamma设置看起来可能会有所帮助。现在不能惹他们,但是今晚晚些时候回家时会。另外,如果我打开一个记事本文档,则用w填充(这似乎是着色的主要问题),结果是它们全都是红色,然后如果我将窗口稍微拖一下,它们就会变成蓝色,然后又变成红色等等。奇怪的。
EDIT2: I couldn't edit the ClearType Registry settings (for some reason they had no effect) so I downloaded GDIPP, had too much trouble, and finally downloaded MacType. From here, I built a custom profile from the Windows 7 optimized one and found the issue. There is a setting called "Optimize for LCD", a couple of them actually. I changed it to Light Anti-aliasing. Now, it ain't super pretty, but the red/blue shadows are gone and the text looks just fine. I'm going to call this one solved for now and say that Microsoft really should put some more effort into their text rendering :P
Download CRU (Custom Resolution Utility) and change from "Default extension block" to "No extension block". Then, either reboot or run restart.exe/restart64.exe and you should have glorious 1920x1080@60hz over HDMI.
You should notice that the TV now detects the signal as "1920x1080@60hz" instead of "1080p 60hz".
Note that you'll lose audio with this method.
I just picked up a similar Sceptre TV (E246BV-FHD) with the same issue.
edit: I'm using this method with an AMD video card and am noticing that my display settings are being reset on every reboot (monitor positions/orientations). I'm looking into this now.
If you're still using a nvidia card, look at the "Change resolution" section of the nvidia control panel. There should be "Ultra HD, HD, SD" resolutions as well as "PC" ones. If you can select 1920x1080 in the PC section, it should work without needing to use CRU. My PC section maxed out at 1680x1050 for some reason.
You can try playing with the signal type, but it didn't help for me. And those options aren't present when in PC mode, so the colors are definitely off (not a big deal by itself, but it's noticeable in a multi-monitor setup). But that's for another day. At least everything is crystal clear now.
edit2:我重置所有配置文件,重新启动,设置所有位置和方向,然后再次使用cru进行修改。似乎在启动时发生了某种切换。现在一切都好。
