Did you recently upgrade to a new gaming console that is capable of displaying a 4K picture? If so, you may be looking into upgrading your TV to take advantage of the increased resolution that the console provides. Here are a few things that you want to keep in mind when looking at HD TV reviews.
A big factor that you must consider when buying a 4K TV is what kind of panel the TV has. Many TVs have been using LED for years, which provides a very great picture with some limitations. However, there are also OLED TVs that are new and can offer an even more phenomenal picture for when you are in a gaming session.
The main trade-offs between these two types of panels will be contrast ratio and burn-in. OLED panels are going to have a fantastic contrast ratio because every single pixel has its own light source. This means that if the screen is supposed to be pure black then the pixel will be turned off completely. You'll no longer have white bleed over from the backlight to light up a very fine amount of black pixels in a game.
However, OLED TV can have issues with burn-in. This may not be a problem for normal TV watching, but it can be for gaming where you have a static image on the screen for potentially hundreds of hours. If you have concerns about burn-in because you play the same game all the time, consider an LED TV to give you peace of mind.
Another thing to pay close attention to is the refresh rate of the TV. New game consoles have the capability of outputting an image at 120fps, but the TV needs to support that option to display it. Unfortunately, not all TVs are capable of displaying 120fps. You should look for information about the refresh rate. Anything that advertises 120Hz for the refresh rate is going to be capable of producing an image that looks very smooth in supported games.
The final thing that you'll want to look into is the latency, which is how long it takes an image to refresh on the screen. This is not typically a problem in movies and TV shows where the TV can delay the sound to be in sync with the picture. Video games are treated differently though since you want a TV that has very low latency so that when you press a button the action happens on screen as quickly as possible. A low latency TV is always going to perform better than a high latency TV in this area.
