Hi,

First what is the difference, if any, in the video quality of DVI and HDMI? Do they both handle 1080P HD? Also on a PC I am rebuilding I have a decent video card and LCD monitor. Each support 1080p HD and I have both DVI and HDMI cables for them. Is it ok to just keep both of those cables connected, just to switch back and forth to compare maybe?

Thanks,

Grand Master

You can have two connections connected to 2 of the monitors ... I mean DVI: from PC to the DVI monitor.... HDMI: from PC to other HDMI monitor... so you can have multimonitors setup.

If you have 1 monitor, you pick either DVI or HDMI.... either way you want... but it would be too much trouble to switch back and forth on 1 monitor.

Yeah but is there any marked difference in the video quality or capability between the 2?

I am sorry that I forgot that question about the difference... since the question has been answered for you. Richard is right ... no difference between the connections.

HDMI is DVI with audio if you want to say it simply. The specs are similar that's why you can have a DVI > HDMI cable without any converters or things like that. They just match the PINs but leave off the Audio ones for DVI. So yes, there is no difference in quality at all as they are exactly the same :)

+1 both have their advantages and disadvantages.

HDMI is better because it also carries the audio so if you want to ever hook your PC up to a TV and use its built in speakers then you don't need to try and hook up a separate audio connection.

DVI can depending on type also carry an analogue signal...and the connector has screws so is more secure.

DVI also carries Analog so you can use a DVI to VGA adapter on a DVI port, HDMI is only digital

Not entirly true....only DVI-I (or the uncommon DVI-A) carry analogue. DVI-D doesn't carry an analogue signal.

If we're talking about GPUs, then there will be a DVI-I port, therefore DVI will carry analog in this scenario

      Free Software Foundation Europe pushes EU to force Google to allow AI uninstalls on Android by Paul Hill Credit: Pexels Users should be able to fully uninstall AI-based features from Android devices and be able to access interoperability functions, free from Google’s verification requirements, the European Commission has heard as part of an Android interoperability consultation under the Digital Markets Act. These measures were proposed by the Free Software Foundation Europe (FSFE) last week when it submitted its documentation. The FSFE noted that Google had started silently installing AI models without telling users. It noted that the EU’s DMA requires companies like Google to allow users to uninstall pre-loaded software from their devices, but in the case of the AI models Google is installing, they reinstall if you delete them, contravening the DMA. To get Google back under control, the FSFE has told the European Commission that there needs to be improvements within the Android Open Source Project (AOSP). First, it said that users should be able to fully remove pre-loaded AI components from their devices, with companies being prohibited from silently reinstalling or reactivating them. Second, access to Android interoperability features should not be contingent on registration, authorization, or contractual relationships with Google. This pertains to Google’s attempt to force developers to register with Google, even to publish apps to alternative app stores like F-Droid. Discussing its submission, Lucas Lasota, FSFE Legal Programme Manager, said: Google is planning to roll out its Android Developer Certification in September 2026. This will force every Android app developer to register with Google before their software can be installed on certified Android devices, but it should affect those who have removed Google Apps from their device. The program is controversial because it entails the signing of contracts and payment of account fees to Google, as well as the handing over of the identities of developers. It said: The FSFE said that if the Commission’s draft measures remain unchanged, then Google will be allowed to make developers verify their identity. The FSFE believes that asking developers to register is contrary to the text and spirit of the law. In summary, the FSFE has told the Commission that no developer should need a Google account, a Play Store presence, or any agreement with Google to access Android’s interoperability features.
