How to distinguish them, differences and how to know which one to use

Not all HDMI ports on your TV are the sameand that is why we are going to teach you to distinguish them and to differentiate between those of yours. Thus, you can have a little more information to decide which of them you want to use for each device you are going to connect. Let’s start by telling you HDMI types that your TV can havesomething that also depends a little on the year in which you will buy it. And then, we will tell you the main differences between one and the other. HDMI types on your TV On your TV, you can mainly have three types of port HDMI. On the one hand are the normal HDMI, the standards that your TV brings. They are usually the same, although they do not usually specify what the standard version they use. This you will have to look at the TV manual Some more modern televisions have at least A port with HDMI ARCor with the acronym arc in parentheses. This technology is implemented from HDMI 1.4, and are connectors with The sound return channelwhich means that it extracts the sound to send it to an audio team. In the most modern televisions, especially since 2019, the ARC possibly indicates that it is An HDMI connector 2.1. These use the format EARC Successor of the arc of the previous ones (means “enhaled arc” or “improved arc”). It is a more advanced technology, so that the teles can send any high -resolution multichannel digital sound format. In many cases it is not possible to distinguish HDMI 2.1 of your TV. If the TV is modern, it is possible that it is the Puerto Arc that appears in it, although it is also possible to be an anterior arc version. Come on, the ARC can be normal arc or EARC, you will have to look at the specifications or technical card of your TV to get out of doubt. What port HDMI use In the event that you have a sound barA/V receiver or an audio equipment connected to the TV, you will always have to use the port that appears as ARC or EARC. These are HDMI ports prepared to improve sound shipping, and that is why they are the specific ones to use. The ARC protocol is not activated by default. This means that when you connect a sound bar, you may have to go to your television sound output settings and indicate that you do not want the TV speakers to be used, but the HDMI ARC exit. You have to start from the idea that HDMI with the ARC is the most modern port. Therefore, in the event that you do not have a sound bar, it can be the one you want to use for your game console or external smart TV device.

These are some of the sections in which you can see what novelty the new iPad Air offers. Screen and design Like its predecessor, the IPAD Air 2025 is available in two screen parts: 11 and 13 inches. Beyond this, as far as design is concerned, the weight is the other difference. The 11 inch weighs 460 grams In front of the 462 grams of the 2024 model, while the 13 -inch weighs 616 compared to the 617 grams of the iPad Air 2024. As you can see, the weight difference is not practically notable. Another of the screen differences is that the resolution in the new models is FullHD+. It is the only one, since the new generation maintains the same Nits (500 in the 11 -inch and 600 in the 13 -inch), the same refreshment rate (60 Hz) and both models have True Tone technology. Performance This is the section in which the most different can be noticed between the iPad Air 2024 and the iPad Air 2025. The previous model came with the chip M2while the new generation of iPad Air integrates the m3 chip. This chip is not new, but can already be found in the Macbook Air 2024. If we compare the M3 chip With the M2, you can see a remarkable advance. Performance improves, as well as energy efficiency. Although both chips have eight -core CPU, the M3 offers much faster processing speeds. The M3 chip, in turn, has motors from Prore decodingallowing fluid and real -time reproduction, even if you reproduce high resolution images. It also incorporates AV1 decoding, very useful in 4K and 8K resolutions. Software Another of the differences that can be observed between the iPad Air 2024 and the 2025 model is in terms of software. The new model comes with Ipados 18 and those who buy the new iPad will be guaranteed updates for five years. In addition, it is Compatible with Apple Intelligence (although it will also be with the previous model). Is the new iPad worth? The surprise has been capitalized by knowing that Apple has launched a new iPad in less than a year. Yeah You want to have a better processorthen it will be worth acquiring the new … Read more

What is, news, differences, and how to access the new artificial intelligence model of ChatgPT

Let’s explain What is and what news brings GPT 4.5the new artificial intelligence model launched by OpenAI for Chatgpt. Two years after a GPT 3.5 that revolutionized the industry and the technological world, this transition model between GPT-4O and GPT-5 arrives. We are going to start this article explaining what GPT-4.5 is, in case you still don’t know what this type of technology is. Then, we will tell you the novelties that it brings and how it differs with ortho models. And then, we will tell you how you can access him and those who can do it. What is GPT-4.5 GPT-4.5 is the artificial intelligence model of GPT-4 successor. GPT models are the artificial intelligence engine under chatgpt, The technology that makes it work. Over time new versions are coming out, and each of them have improvements that then apply to Chatgpt. Therefore, you don’t change chatgpt, but you can choose between the different engines that make it work. Of course, some are free and others are paid, and some work in one way and others from another. In the case of GPT-4.5, It will be the last model without a chain of thought. Some alternatives such as GPT-4O They are able to reflect on your question and how to face the answer before answering. However, this new version does not, so it looks more like GPT-4 than to other later models. GPT-4.5 is The largest and most advanced language model Posted by Openai to date. Not only is it more natural, but it has A much higher knowledge base with which to be able to face more complex challenges in scientific disciplines. It also improves its ability to solve logical problems. But one thing you have to know is that we have a version of GPT-4 freefor now GPT-4.5 is going to be paidand only subscribers can use it. The logical thing would be to think that they later take out a “mini” version somewhat more limited to use free of charge, but for now there is no date for it. How is GPT-4.5 As we have advanced a little higher, GPT-4.5 continues to advance in the resolution of tasks, and thanks to having a greater knowledge base improves the responses of their predecessors in logical problems, and is able to answer better questions in scientific disciplines. In general, The less hallucin modeland it is more truthful in your answers, a logical improvement for each new version that is coming out. But one of its most differentiating characteristics is in Emotional intelligence. This model is able to detect the tone in which you write a message, and respond in a consistent way. For example, if you notice frustration in your message the answer will be calmer and diplomatic. In addition to this, shows more solidity in complicated questions whose answer is not clear. For example, if you ask what the language would tell you that Nolo knows, and will explain that scientists do not believe we know it because they were invented before written records. Then, it will give you a series of points about what is currently known. To get this, OpenAi has added New supervision techniques for the learning of your model, which bind to traditional methods such as the supervised fine adjustment (SFT) and learning by reinforcement based on human feedback (RLHF). In short, we have a model that will significantly improve the answersand also the tone with which it responds in the cases in which you write in an emotional way. How to access GPT-4.5 For the moment, GPT-4.5 is going to be a payment model. The first who can start using it are the subscribers of Chatgpt Prothe company’s 200 dollars plan. But from next week it will also begin to be available in the subscription Chatgpt plus of $ 20 and Team. For the moment Nothing has been said about a free version. Normally Openai always leaves their best models for those who pay, so it is logical to think that it will take a few months to launch a free version, and that it will have some type of limit when it arrives.

The main differences between the Galaxy S25, S25+ and S25 Ultra

by

Samsung just presented the new Galaxy S25, S25+ and S25 Ultrawith very interesting news. It is true that the changes with respect to the previous year’s models are not that many, but even so, they represent another step forward in the evolution of the brand’s flagships. At the design level, the most important modifications are seen in the Galaxy S25 Ultra. This version has abandoned its square aesthetic to make way for more rounded corners. While the S25 and S25+ are clearly continuous bets when putting them face to face with their predecessors. In this article we are going to take the opportunity to review the main differences that exist among the three members of the Samsung Galaxy S25 family. Although there are several things in common throughout the range, not only in specific hardware issues, but especially at the level of software features, we believe it is important to place special emphasis on the elements that distinguish these mobile phones from each other. The main differences between the Samsung Galaxy S25, S25+ and S25 Ultra The first difference, and the most logical, has to do with the size of the screens and the general dimensions of the devices. The three Galaxy S25 come equipped with 2X AMOLED panels; that of the base version is 6.2 inches with FHD+ resolutionwhile that of the S25+ is 6.7” with QHD+ resolution. On the Galaxy S25 Ultra, meanwhile, the screen is 6.9 inchesalso with resolution QHD+. It is worth noting that in all cases an adapted refresh rate of 1 to 120 Hz, Vision Booster and adaptive color tone are offered. If we focus on the general size and weight of the new Samsung smartphones, the breakdown is as follows: Galaxy S25: 146.9 x 70.5 x 7.2 millimeters/162 grams; Galaxy S25+: 158.4 x 75.8 x 7.3 millimeters/190 grams; Galaxy S25 Ultra: 162.8 x 77.6 x 8.2 millimeters/218 grams. With regards to the camerasthe Galaxy S25 and S25+ feature exactly the same front and rear sensor configuration. Of course, these differ from those implemented in the Galaxy S25 Ultra, which is the top of the range of Samsung’s brand new family of models. Below is the comparison: Galaxy S25 and S25+ Galaxy S25 Ultra rear cameras 50 MP main sensor with optical image stabilization, f/1.8 aperture and 85° field of view.12 MP ultra-wide-angle sensor with f/2.2 aperture and 120° field of view.10 MP telephoto lens with 3x optical zoom, f/2.4 aperture and 36° field of view. 200 MP main sensor with optical image stabilization, f/1.7 aperture and 85° field of view.50 MP ultra-wide-angle sensor with f/1.9 aperture and 120° field of view.50 MP telephoto lens with 5x optical zoom, optical image stabilization, f/3.4 aperture and 22° field of view.10 MP telephoto lens with 3x optical zoom, optical image stabilization, f/2.4 aperture and 36° field of view. front camera 12 MP sensor with f/2.2 aperture and 80° field of view. 12 MP sensor with f/2.2 aperture and 80° field of view. Storage, RAM and battery The new Samsung Galaxy S25, S25+ and S25 Ultra are powered by the chip Snapdragon 8 Elite for Galaxyfrom Qualcomm. The three models also come equipped with 12 GB of RAM, but they differ in the number of memory and storage configurations available. The standard Galaxy S25 will be offered in three variants: 12 + 128 GB, 12 + 256 GB and 12 + 512 GB. For its part, the S25+ will be available only in versions with 12 + 256 GB and 12 + 512 GB. While the Galaxy S25 Ultra will be the only one with a 12 GB RAM + 1 TB storageand will also be available in intermediate versions with the same amount of memory, but with 256 or 512 GB of internal space. In the batteries section, also there are logical differences among the three new Samsung phones. The Galaxy S25 arrives with the smallest, which is 4,000 mAh and supports wired fast charging up to 25 watts, wireless charging and PowerShare. In the case of the S25+, we find a much more generous battery of 4,900 mAhwhich supports fast wired charging of up to 45 watts, and also has support for wireless charging and PowerShare. For the Galaxy S25 Ultra, Samsung did not want to give surprises either. The smartphone arrives with a battery of 5,000 mAh which supports fast wired charging of up to 45 watts. It also integrates PowerShare and recharges wirelessly, as it could not be otherwise. Batteries are the segment in which Samsung has unfortunately stagnated in recent years; especially when talking about their flagships. Especially if we consider that other manufacturers have already begun to adopt accumulators with higher capacities and much higher charging powers. Here it is evident that the Koreans are falling very short. The Galaxy S25 are a continuous bet As we indicated at the beginning, the changes that come with the Samsung Galaxy S25 are much less drastic than those we saw in previous years, and the same applies to the differences between the three models. When reviewing the specification tables, it quickly becomes evident that there are more similarities than differences in key elements. Same chip, same RAM, same connectivity options (WiFi 7, 5G, Bluetooth 5.4, etc.), same water resistance rating (IP68), and so on… We must not forget that this year Samsung has opted to bet its most important chips on the software experience with Android 15/One UI 7 and its artificial intelligence functions. That is where it seeks to compensate for the lack of brilliant modifications at the hardware level. The Galaxy S25, S25+ and S25 Ultra can now be reserved and will be available from February 7. The first two are offered in grey, navy, blue and mint; while the Ultra version has variants in blue titanium, gray titanium, silver titanium and black titanium.
