Hello, I'm looking for a device that fixes overscan, so that I can connect my Wii-U into it, and then connect the device to my HDTV. As many people are aware, the Wii-U doesn't play it safe and puts important text/symbols right at the edge of its display, thus being cropped by most HDTV's, as most HDTV's have overscan, and many of them have no possible way to fix it (not even within the service menus).

Now, please don't say "By a new TV!". That's nearly impossible for me. You see, I'm very sensitive to "input lag", and I got very lucky and found the Panasonic L32X1 brand new, and purchased it. The X1 Panasonics are considered to be the ultimate gaming HDTV's, because they have anywhere between 2ms of lag to at most, 8ms. And buying a HDTV that has anything over 16ms will not be tolerated by me. So I was out of options, and had to get a lag-free TV, and this was my best choice. So I absolutely CANNOT get another 32" HDTV unless its less than 1 frame of lag, AND has zero overscan, and almost no blur (Panasonic ALHPA panels are best with this, no post-processing needed).

I recently used a Micca HD Media Player that had a option called "FIT" that can detect how much overscan my TV applies, and then zooms to fit the pixels nearly perfectly. Thus, no overscan. I thought to myself "Well, if this little Media Player can do that, then surely there is something that can act as a bridge between my Wii-U and HDTV that does the same thing".

So what do you guys suggest? Any devices?

P.S. I suppose I "could" wait for a firmware update from Nintendo that has a global screen adjustment (afterall, the Wii-U eShop has this option along with the Internet Browser). But Nintendo is not always ready to take suggestions from customers. HOWEVER, if you google "WiiU Overscan", you will see LOTS of pages complaining about this, already within the first few days after launch! So to further press this issue, I made a carefully worded thread on Nintendo's support forum. Please if you wish to get Nintendo to listen, join in and complain with me. Thank you - http://techforums.nintendo.com/message/79214#79214

Sounds as you are talking about a scaler.

Abundant OTA television is what makes this country different from all others. Lets keep it this way.
The Internet is no place for streaming video.

I appreciate you trying to help, but ...........a Scaler? Wouldn't this be some big bulky device that had multiple inputs and a remote? (also, the Wii-U is displaying natively on my HDTV, so there is no scaling needed, just adjustment to fix overscan)

Is there anything simpler, or at least smaller that I could use? (if not, let me know what scalers are capable of doing what I need done)

Scalers, including external devices, adds input lag. This includes scalers that have configuraiton settings that shrink the size of images to adjust for overscan -- adding digital overscan adjustment to any device, internal or external, bulky or not, involves image stretching, and thus almost always adds input lag. So you may be stuck if you don't want input lag. If you mean analog overscan adjustments for the left/right edges of the screen, (manipulating the horizontal sync interval, front/back porches), that needs to be added by Nintendo itself into a settings menu. If Nintendo is already framebuffering the graphics, and the framebuffer has sizing capability, then Nintendo could theoretically also add digital overscan (horiz/vertical image stretching) adjustments without adding additional input lag, if it's already scaling internally in real time anyway, while outputting the framebuffer. External digital image stretching solutions (whether scaling or overscan sizing adjustment etc) often forces another layer of framebuffering in order to resize the image.

Try waiting for a Nintendo solution -- they may add a native overscan adjustment to their consoles within a few weeks or months, given the number of complaints. Are you connecting using analog or digital connections?

Thanks,

Using digital HDMI and its displaying the Wii-U in native resolution on my TV.
