Apple Studio Display开机初始化分辨率
如题，目前Studio Display接在普通PC上使用，Windows+Linux+8K DP KVM完美切换，唯一纠结的是开机是初始化分辨率，通过BIOS界面截图显示分辨率为1024x768，此前使用P2415Q显示器，开机分辨率为原生4K，就想问下有朋友的Studio Display在普通PC上开机时的分辨率能正常初始化到原生5k分辨率吗？ 这显示器怎么接普通dp口的windows pc啊？ mailps2 发表于 2022-12-9 19:39这显示器怎么接普通dp口的windows pc啊？
某宝vr线或者vr转接头，就可以了。。。实际这个雷电3接口跑的是DP协议。。。 8K DP KVM有推荐的么？我现在用雷电hub手动切换，每次拔插一下雷电线。 fkpwolf 发表于 2022-12-9 20:08

关键字ckl，然后找8k dp款就行，价格还行，比我此前买aten cs782dp便宜好多了，4个usb口，刚好可以把转接头的两个usb口接上。。。 一样的 开机时就是这个分辨率 糊的[偷笑] yuechsh 发表于 2022-12-9 20:53
一样的 开机时就是这个分辨率 糊的
行吧。。。要么主板bios的锅，要么显卡bios的锅，studio display使用512字节的EDID，4K以下的EDID应该是256字节。。。studio display的5K信息在后256字节。。。 之前一直没在意，刚重启看了下确实是糊的， 估计得接mac才能解吧。pc 只能这样了 pplto 发表于 2022-12-9 21:50

不知道其他超过4K分辨率的显示器是啥情况？ Studio Display是好屏幕，就是对不玩果子的很不友好[雷人] 晓古城 发表于 2022-12-9 21:57

其实，就是 线材贵一些，
然后需要装个 bootcamp 的软件，基本还是完美使用的 lh7q 发表于 2022-12-9 21:54

把之前一台 lg 的34英寸 5k的带鱼屏拿出来测试了一下啊
开机logo 一样是分辨率错误的，需要进系统才正确，所以应该是diy 通病 本帖最后由 lh7q 于 2022-12-15 14:45 编辑

看来大概率是主板bios的锅了，4K以下的edid大小应该256字节，4K以上的edid大小是512字节，扩展信息(displayid)在后256字节，初始化分辨率不正常的，应该是后256字节没有读取造成的？
而nvidia有一个displayid的固件补丁，是用于修正bios及引导界面黑屏，这个补丁应该就是让显卡正确读取后256字节的edid信息？
附上sutdio display的edid信息：

另外，windows下使用bcdedit命令，可以将开机界面设置到4k分辨率，只是主板logo会到左上角， GRUB或者其他黑苹果引导工具可设置的最高分辨率也是4k，这个分辨率跟edid信息的Block 0里的数据吻合。。。 lh7q 发表于 2022-12-9 21:54
不知道其他超过4K分辨率的显示器是啥情况？

呃，好的，其实判断初始分辨率，最好是看logo下面的那行按键提示，如果是高分屏，那行提示的字体会比较粗。。。。或者干脆进bios里，截图看看。。。 lh7q 发表于 2023-8-9 12:45

嗯晚上回去再仔细看下 怎么接游戏机玩？声音输出如何解决？
