  • Notificação do fim do fórum

    Já ando afastado destas lides à uns anos, mas perante as notícias quero também eu só deixar aqui um grande agradecimento ao Roz por criar e ter oferecido esta segunda casa a tantos nós.

    2004 já vai lá bem longe, mas as memórias que levo desta comunidade ao longo de mais de uma década em que por cá andei vão durar para sempre, o PTF foi uma parte integrante da minha vida e um ponto de partida para inúmeras amizades e aventuras offline que nunca esquecerei.

    E claro a toda a comunidade, a todos os PTF sem exceção, um muito obrigado por tudo porque sem vós o PTF nunca aqui teria chegado, e até sempre.

    E em jeito de despedida, um dos melhores videos de sempre:



  • Sonic Boom 2017, Madrid (1-2 Abril)

    Very nice, parabéns a toda a comitiva pelo desempenho, e em particular ao @digos e @KeeChak pela representação em KOF.
  • Random cenas


    PS: só gostava de saber como se põe fotos em grande.
    Não as metas como anexos no teu post.
    Tens de fazer upload da imagem para um site qualquer que aloje imagens, usa por exemplo o:

    http://imgur.com/

    Depois de meteres a foto lá, copia o endereço que tá em "direct link", e quando escreveres o teu post aqui clica ali em cima no simbolo de anexo à mesma mas mete antes esse endereço que copiaste na caixa em baixo onde diz "image url"



  • Lista de Monitores/Tv's e Input Lag Tester

    LISTA DE MONITORES/TV'S TESTADOS EM: <br />http://www.displaylag.com/display-database/<br /><br />
    Input lag is not an advertised specification from manufacturers and has to be hand-tested by people. Till now, it was a slow and cumbersome process. However, thanks to the simplicity and ease of use of the Lag Tester, it is now a reality to be at the forefront of fighting display input lag.
    <br /><br /><br />O método mais fiável e exacto actualmente para determinar lag total de um monitor/tv para jogos é este aparelho:<br />>> http://www.leobodnar.com/products/LagTest/ << <br /><br /><br />LISTA EM: http://www.displaylag.com/display-database/<br /><br />===<br /><br /><br />Problemas do método de fotografia a um "Clone Display":<br />
    Testing for display lag<br /><br />Display lag can be measured using a test device such as the Video Signal Input Lag Tester from Leo Bodnar Electronics [1].<br /><br />Lacking a measurement device, measurement can be performed using a test display (the display being measured), a control display (usually a CRT) that would ideally have negligible display lag, a computer capable of mirroring an output to the two displays, stopwatch software, and a high-speed camera pointed at the two displays running the stopwatch program. The lag time is measured by taking a photograph of the displays running the stopwatch software, then subtracting the two times on the displays in the photograph. This method only measures the difference in display lag between two displays and cannot determine the absolute display lag of a single display. CRTs are preferable to use as a control display because their display lag is typically negligible. However, video mirroring does not guarantee that the same image will be sent to each display at the same point in time.<br /><br />In the past it was seen as common knowledge that the results of this test were exact as they seemed to be easily reproducible, even when the displays were plugged into different ports and different cards, which suggested that the effect is attributable to the display and not the computer system. An in depth analysis that has been released on the German website Prad.de revealed that these assumptions have been wrong. Averaging measurements as described above lead to comparable results because they include the same amount of systematic errors. As seen on different monitor reviews the so determined values for the display lag for the very same monitor model differ by margins up to 16 ms or even more.<br /><br />To minimize the effects of asynchronous display outputs (the points of time an image is transferred to each monitor is different or the actual used frequency for each monitor is different) a highly specialized software application called SMTT or a very complex and expensive test environment has to be used.<br /><br />Several approaches to measure display lag have been restarted in slightly changed ways but still reintroduced old problems, that have already been solved by the former mentioned SMTT. One such method involves connecting a laptop to an HDTV through a composite connection and run a timecode that shows on the laptop's screen and the HDTV simultaneously and recording both screens with a separate video recorder. When the video of both screens is paused, the difference in time shown on both displays have been interpreted as an estimation for the display lag.[2] Nevertheless this is almost identical to the use of casual stopwatches on two monitors using a "clone view" monitor setup as it does not care about the missing synchronisation between the composite video signal and the display of the laptop's screen or the display lag of that screen or the detail that the vertical screen refresh of the two monitors is still asynchronous and not linked to each other. Even if V-sync is activated in the driver of the graphics card the video signals of the analog and the digital output will not be synchronized.[3] Therefore it is impossible to use a single stop watch for display lag measurements, nervertheless if it is created by a timecode or a simple stopwatch application, as it will always cause an error of up to 16 ms or even more.
