The EVGA GTX 1060 3GB has three DisplayPort 1.4 connectors it has one HDMI 2.0b connector along with a DVI-D connector.
The MSI B350M motherboard with the R5 2400G also has HDMI 2.0b support. So even the integrated graphics is powerful with the gaming rig.
The Asus PB287Q has a pair of HDMI 1.4b ports and one DisplayPort 1.2. The HDMI are able to 3820×2160 but only at 30fps. DisplayPort is needed to achieve 60fps.
HDMI 2.0 or DisplayPort 1.2 or above is required to achieve 60Hz at 3840×2160. Even with HDMI at 1920×1080 I was not able to achieve 10-bit color as claimed by Asus.
WINDOWS AT 4K
Be default Windows 10 will use a 150% setting for 4K panels. This is to improve the readability for users who may not have the ability to read fine print on the high dot per inch displays.
The problem is that this can cause a lot of flicker as some components in Windows are not yet configured for 150% of normal size etc. Hopefully this will be fixed soon but it is likely there are a lot of components to be altered to handle the screen features properly.
ASUS PANEL DEFECTIVE
After testing several cables and video sources, it has become apparent the Asus PB287Q has a faulty logic board. The HDMI ports work however the DisplayPort does not seem to work. HDMI 1.4 can only achieve 4K30 which degrades the capability of the monitor with the faulty DisplayPort.
The problems with the logic board seem to be worse than a bad DisplayPort interface. This monitor is made with an older logic board that is obsolete. Testing known good cables suggested problems with bandwidth may have been a factor.
I called NewEgg and they sent a voucher for UPS to sent the panel back. The monitor was expected to be fine as new in the box but the DisplayPort does not work. This means the panel will not reach 60 Hz at anything above 1920×1080.
Not many ISP panels at the 3820×2160 segment of the market but there are a few. The Asus PB287Q was the only affordable 4K panel from Asus available.
NewEgg had no problem with a refund. I was looking at more expensive monitors mostly to see what was available with Deep Color and IPS class color.
STEAM LIBRARY AT 4K
Every week more games are added subject to available disk space. The current 4TB disk that is hosting the game library is nearly its capacity. There is room for 2 more hard disks in the chassis and there are 2 available SATA ports so is possible to add more storage.
The steam client itself needs to be redesigned to be better able to cope with high resolution and high DPI displays. The client seems to be designed for 1024×768 fixed which needs to be revamped to be dynamic so that as panel resolutions rise the client does not become unreadable.
ORIGIN LIBRARY AT 4K
The Origin client itself needs to be redesigned to be better able to cope with high resolution displays. Clearly the game library is centered in an array that seems to be hard coded around 1920×1080. EA needs to work on their client as well as more gaming enthusiasts now have 3840×2160 displays.
UPLAY LIBRARY AT 4K
The Uplay client actually does not look bad at 3840×2160 which makes it more usable. Sections can be collapsed but unlike Steam Uplay shows an expired item which in Steam is usually removed from the library.
ARC LIBRARY AT 4K
The Arc client is another example of a design that needs work on it. The client is nothing but a glorified web page rather than an adaptive design.
At present Origin and Steam can change the size of game icons but other clients do not seem to have that capability. At 3840×2160 small text is hard to read and high DPI displays are becoming more and more common.
Battle.net and Bethesda use a sidebar menu which is not as useful at all compared to the way Steam and Origin present games. These need to be redesigned so that on higher resolution panels the clients will be easier to use.
NEED A NEW VIDEO CARD OR 3
Inquiring on the AMD forum over the 3820×2160 resolution and what cards can handle that without problems. I have not seen many problems with higher resolution displays with Radeon cards. Problems are more driver related than anything with the one on Windows update being the most stable.
The RX 570 is comparable to the GTX 1060 3GB for gaming performance. The cards come with 4GB or 8GB but most cards on eBay are the lower cost 4GB models. The more expensive RX 580 is also available in 4GB and 8GB versions. The RX 570 4GB is now selling for under $100 shipped on eBay. The 8GB cards are more desirable for several reasons but having abundant VRAM allows games to load more assets speeding up loading times.
AMD cards are outright inexpensive and with more VRAM it is useful for using 3D packages for game artwork development. 3D Studio is well know to want a lot of VRAM. Blender is also rather demanding.
All of the AMD Polaris cards are generally the same as the GTX 1060 with 1 HDMI and 3 DisplayPort with one DVI. DisplayPort has been taking over for due to the low costs and markedly better performance.
The most recent Radeon VII offers a very generous 16GB of VRAM which affords even more capability. Editing game maps can use more VRAM mostly as the entire map has to be display all at once so that pick and place objects are fast..
