Old TV with DVI input

One of our TV's is very old but works perfectly with cable. It is an Olivia KT27HVX LCD display. We run a DVI cable from the box to the TV currently. Picture is good. We are dropping cable in early December and going to use YouTube TV as the alternative. The TV has DVI, S video, component and composite inputs. What would be the best Roku and the hookup (reasonable expense) to get a very good picture? The TV is old but fits perfectly in its current location.

Re: Old TV with DVI input

It may work if it also support HDCP, which it probably does if you used DVI with the cable box. One issue will be the audio. Most Roku's do not have separate audio outputs. I think you could use the Express+, with an HDMI/DVI adapter for the video, and the analog audio as an input, assuming the Express+ will always output analog A/V when HDMI is active. Or you could get some form adapter that converts the HDMI to something else, although it could be cheaper to just find another TV that fits.

Re: Old TV with DVI input

One thing to be very cautious about with those older TVs is the resolution they support. Many of the old sets with DVI connections only accept 1080i, and no current Roku can output that. They also may not support 720p, in which case no Roku will work on your TV. Since almost every Roku only has HDMI outputs, and only support 720p, 1080p and 2160p (4K), they won't work on a display without such support. And there are few if any other devices available today that would work either.

Re: Old TV with DVI input

I bought the 3910RW. Unplugged tv and plugged HDMI end of DVI cable from TV into Roku. Plugged the sound cables into TV from Roku. Everything worked except there is a reddish pink screen over everything. Probably not a fix - right?

Re: Old TV with DVI input

This works for my circa 2002 Sony KV-34XBR800 (1080i not p) with ROKU Express+ & HDMI to DVI cable. Must redo it every time the Sony is turned on.

TV power on, screen is black

ROKU cut power briefly (remove cord)

Wait for home screen, has magenta hue

Choose SETTINGS, DISPLAY TYPE, 1080p, OK, FORCE 1080p

Wait for reset, choose OK CONFIRM, color is fixed.

Re: Old TV with DVI input

I would love to know/find/build a device that forced back resolution to the ROKU, TIVO, etc.  I have a crazy nice plasma monitor/TV that has HDCP support in a DVI-D connection.  The plasma is great at 720p BUT the ROKU (any - I have 5 of them) ALL revert to 480p when they turn on and I have to play dancing screen chess to force resolution.  What is the ROKU looking for in regards to a hand shake and no middleware solution to place between the plasma and the device?  I have a similar problem with the newest TIVOs while the older TIVOs retained my forced resolution settings.

I'm sure there's boxes that can be placed in the chain to set the EDID info as you require. The problem is, it's likely not going to be cheap. This page offers a number of them, starting at $30 but quickly going over $100.

Re: Old TV with DVI input

OS 9.4 has fixed this problem for my old Sony. It automatically detects 720p and displays correctly.

That should be welcome news for all the Express+ users that are only using the analog outputs. Assuming the same fix is carried over.
