I have a Philips BDM3275 4k monitor which I connected with HDMI.  Very good for CAD work.

 

Several times a day the display would blank for about 5 seconds - and at very annoying times!

 

More recently the display dropped into what appeared to be a spilt display mode where neither half of the screen showed any image sync - just some multi-coloured lines. Re-powering the monitor and all was well again. This happened just the one time.

 

So I decided to hook up the monitor with a display port cable and all has been good for several days now.

 

So I am wondering how good the leading edge HDMI specs are, or my combination of gear.

 

Gear here:

 

Monitor Philips BDM3275 (3840x2160@60Hz)

 

Video Card Asus  ATI Radeon RX 460 Graphics 4096MB

 

Mother Board  Asus P8Z77-V LX (LGA1155)

 

CPU Intel Core i5 2320 @ 3.00GHz

 

Windows 10 Home 64-bit

Sounds like it could have been a dodgy HDMI cable. Was it a 4k spec cable?

Good point on the cable - Not sure now if it came with the monitor or the video card or a previous monitor.

 

On the cable:

 

High Speed HDMI Cable with Ethernet

 

AWM E101344 Style 20276 VW-1 80C 30V Space Shuttle-Z

 

I will do some more research.

According to this link a High Speed HDMI cable should be good for 4k video:

best to use a displayport cable for 4K 60Hz .... if you have the port on your graphics card

 

HDMI is very sensitive to cable movement or cable problems ... i shouldn't happen, no, but i have a lot of those blank screen moments with HDMI - does it need to negotiate a dfferent level of stuff compared to DP perhaps?





Swype on iOS is detrimental to accurate typing. Apologies in advance.

I used the High Speed HDMI cable because I had it in use on another video card and monitor combo.

 

I am running the display at 4k 60Hz..

 

Display is very stable now with the display port cable.

No problem using my monitor... Use it pretty much all day... 

 

Use it on 3840x2160 at 60Hz.

 

Display is set to Economy mode.

 

I find the brightness very good and no flicker as I search around the screen. Don't use the monitor for gaming.

 

Running 4 apps in 4 panels makes my eyes work very hard.  Pleased I didn't get a 27 or 28 inch display.

 

Have wondered if a 40 inch screen might have been even better (and cheaper) but my wife might notice the upgrade!
