4K - goes to black screen, 1080 is fine

[Adrian Brown]

Please help, i have just completed the following build.
Adata XPG SX8200 Pro 1TB M.2 SSD PCIe Gen3x4 Internal Solid State Drive
AMD Ryzen 7 3700X Eight Core 4.4GHz,
ASUS ROG STRIX B550-E GAMING Motherboard CPU Bundle
Corsair 16GB (2x 8GB) 3200Mhz DDR4 Vengeance LPX
Aerocool 650W LUX RGB Bronze Certified Power Supply
Cooler Master MasterBox MB600L Gunmetal ODD ATX Tower Windowed Gaming PC Case
Corsair Hydro Series H100x 240mm PWM Liquid CPU Cooler CW-9060040-WW
Seagate Barracuda 2TB ST2000DM008 SATA 6GBs 3.5'' Internal Hard Disk Drive - OEM
ASUS TUF Gaming AMD Radeon RX 5700 XT 8GB GDDR6
All seems to be working fine, i am playing through my Philips 65, 6700er series TV. However when i try and change the resolution to 4k, i just get a black screen and 'no signal', everything else works fine on the TV in 4k. Nothing seems to overheat.

Any suggestions...

Are you connected to the graphics card outputs? Not the motherboard display outputs?

Yes HDMI from G'card to TV.

Asus made the way crappiest 5700 XTs and if black screen happens during gameplay, it's likely because of card's garbage bad cooling.

Also instead of very overpriced marketing hype liquid cooler you should have put that money on proper PSU instead of that Aerocrap garbage.
Ditto for motherboard being £50 overpriced for B550.

Sorry i thought i had asked for advice, not your opinion and bashing of my build. The only game i have played so far is COD MW2, the original one, that worked fine...

Maybe try a better HDMI cable.

I was thinking that, but everywhere i looked it seemed to suggest with HDMI leads, they either work or they dont, quality makes no difference. Will try that tomorrow...

I don't think some of the older ones even supported 4k.

No, some only support HDMI 1.4, some support HDMI 2.0. Cables can have different bandwidth.

HDMI Versions vs. HDMI Cable 4K

Full 4K support was introduced with HDMI version 1.4. However, you can only be sure with cables certified as "High Speed" to support the high bandwidth requirements of HDMI 2.0. Cables classified Version 1.3 mostly don't work for HDMI 4K functionality. The following list will give you a rough orientation.

HDMI cable 1.0 – 1.2 – no 4K Ultra HD support
HDMI cable1.3: Probably no 4K support depending on the cable
HDMI cable1.4: 4K support very likely, but not guaranteed
HDMI High Speed Cable: 4K Ultra HD support guaranteed

Conclusion: No need for a 4K HDMI Cable if you choose High Speed

Don’t let you fool by shops or cable merchants with expensive HDMI 2.0 Cables or “4K HDMI Cables”. There is no such thing and there never will be! Just go for a reasonable HDMI High Speed Cable and save your money. High Speed Cables provide 100% compatibility for now and for future HDMI 2.0 contents. The display quality is all the same. You don’t need any new fancy cable hardware

Thats what i am using at the minute. I have just found an article that the problem could be my philips TV.

Not all the HDMI ports on that TV support 4k at 60 HD:

Computer inputs on HDMI1 up to 4K UHD 3840x2160@30 Hz
Computer inputs on HDMI2/3 up to 4K UHD 3840x2160@60 Hz
Video inputs on HDMI2/3 up to 4K UHD 3840x2160@60 Hz
Video inputs on HDMI1 up to 4K UHD 3840x2160@30 Hz

Make sure the HDMI cable from the PC is plugged into port 2 or 3 on the TV.

Plugged into HDMI 3, luckily it was the easiest to access as its on the side not the back.

 

[mickyflinn]

Try port 2.

I feel so stupid now... bingo its working and sexy….

PSU is one of the more important parts of PC and not something bough with left overs after spending on fashion and hype.
(and second longest potential usage life part after case)

That Aerocool would have been not recommended/at best low end already decade ago.
And bulk capacitor of primary is certainly from Chinese trash bag.
Besides being such undersized that's probably more like some 350W PSU. 450 microFarads is usual capacitance for 650W PSUs.

Suspect secondary filtering capacitors aren't any better.
