Windows 10: HDMI to DisplayPort Will it make it 4k@60 compatible?

Hello, I just had a question regarding a small thing that maybe some people can help me out with. I have one single HDMI port on my computer and a VGA port. I also have Intel HD 630 Integrated Graphics. This is rated for up to 4096x2304@24Hz on HDMI, and 24-30hz counts for anything above 1080p I have noticed, but, it is also rated for up to 4096x2304@60Hz on DP, and eDP. I am running off of a Sony TV, with only HDMI ports, and supports up to 4k@120z if I remember correctly on certain things. I was wondering if I connect a 4K@60Hz capable HDMI to DP adapter to my computers HDMI, and to my T

:)

 

StarTech Announces New DisplayPort to HDMI and Mini DisplayPort to HDMI Adapters

StarTech.com, a leading manufacturer of hard-to-find connectivity parts, has announced the availability of three new Active 4K-capable Video Adapters, which enable users to stream audio and video from their DisplayPort 1.2 or Mini DisplayPort 1.2-equipped computer to an HDMI-equipped TV, monitor or projector. The new adapters offer active signal conversion, which unlike passive video adapters does not require a multi-mode DisplayPort (DP++) source signal, greatly expanding compatibility options.





StarTech.com's new DisplayPort and Mini DisplayPort to HDMI 4K adapters include the following:

• DisplayPort 1.2 to HDMI 1.4 4K Adapter (SKU: DP2HD4KS). : MSRP: £31.25 (GBP exc. VAT) in the UK.
• Mini Displayport 1.2 to HDMI 1.4 4K Adapter (SKU: MDP2HD4KS) : MSRP: £31.25 (GBP exc. VAT) in the UK.
• Mini Displayport 1.2 to HDMI 1.4 Adapter - White (SKU: MDP2HD4KSW) : MSRP: £31.25 (GBP exc. VAT) in the UK.

"These are the next generation of DisplayPort and Mini DisplayPort adapters. Although DisplayPort to HDMI and Mini DisplayPort to HDMI adapters have been around for some time, these adapters are unique because they enable users to realise the full benefits of 4K display technology" said Karishma Punwani, Product Manager for StarTech.com's DisplayPort product line. "By taking advantage of 4K display technology which provides four times the resolution of high-definition 1080p, these adapters allow you to view your digital content (video and images) with astonishing detail and quality.

Features of the new adapters include:

• Supports video resolution up to 4K (4096 x 2160 @ 30 Hz), stereoscopic 3D
• Backward compatible with 1080p displays
• 5.1 Surround Sound support
• Fully compliant with DisplayPort revisions 1.2/1.1/1.0
• Compatible with Intel Thunderbolt devices capable of outputting a DisplayPort signal
• Compatible with video cards that are not capable of outputting DP++ (multi-mode) signals
• DPCP (DisplayPort Content Protection) and HDCP (High Definition Content Protection) compliant

The DisplayPort to HDMI and Mini DisplayPort to HDMI 4K adapters will be available from Insight, Misco, Amazon.co.uk and Dabs and is also distributed by Enta, Ingram Micro and Exertis Micro-P.

 

is my spare hdmi cable bad

Your link is to a DisplayPort cable. It looks similar to an HDMI cable, but it is not compatible. (Look closely at the connectors.) You want an HDMI cable.

DisplayPort - Wikipedia

HDMI - Wikipedia

Your KDL-42W800B is a full HD (1080p) display., and its specifications don't list any refresh rates above above 60 Hz. You wouldn't get any benefit from an HDMI 2.1 cable (for 8k/60 Hz or 4k/120Hz). Or even a certified premium HDMI 2.0b cable (for 4k/60Hz).

Cables like those rarely fail, in normal use. The connectors (on the cable, TV, or PC) can be damaged.

 

HDMI cable not detected by computer

I want to connect to a monitor or TV with HDMI. No signal to either. Monitor says "no signal coming from your computer".

I have tried with no success:

• HDMI directly into Nvidia 980 HDMI slot
  
• HDMI directly into motherboard slot, Intel i6700k with integrated graphics
  
• HDMI indirectly into HDMI(female)-to-Displayport(male) adapter, into Nvidia 980 Displayport slots
  

I have verified:

• Cable plugged into second computer, connected fine to monitor and TV
  
• Tried different HDMI cable, same results on both computers
  
• Displayport slots on Nvidia 980 work on monitor with DP-mDP cable
  
• Both monitor and TV are 4k. Output is 4k on other computer, and 4k using Displayport on this computer.
  
• Used newest graphics driver for Nvidia 980
  
• Used old graphics driver (2020) for Nvidia 980
  

All cases, other computer connected successfully and this computer received "no signal"

Other than the hardware checks and the driver checks, I am not sure what other steps I should try.

Since it applies to both Nvidia 980 and motherboard, and since Displayport works but HDMI through Displayport doesn't work, I feel like there is some issue in the computer working with HDMI signals.

Thanks, Ahmad
