Monitor as a television. - Connecting an LCD monitor to a set-top box (TV)

Best answers

Can I connect a Philips Brilliance 170P LCD monitor to a WIWA HD90 MC set-top box as a TV, and what cable/adapter do I need?

Yes, the recommended setup is an HDMI-to-DVI cable for video plus a 3.5 mm AUX cable for sound if the monitor has audio input [#16735688] The antenna should go into the set-top box, because the decoder has the DVB-T tuner [#16735715] There is a catch: this monitor is limited to computer-type resolutions up to 1280×1024, has no HDCP, and will likely work only at 1280×720 from the decoder, so HD content may not display properly and you may see black bars with 16:9 channels [#16735830][#16736297] An 18+1 DVI cable should be enough, though 24+1 was suggested as a more future-proof choice [#16736501] The decoder may also allow Wi‑Fi only if it supports a USB Wi‑Fi module, but internet use is generally limited to whatever apps the decoder itself provides [#16735688]

    Hello,
    I have already searched a few topics but none of them explained the matter to the end.
    Well, I would like to connect a Philips Brilliance 170p LCD monitor to a set-top box (WIWA hd90 mc) as a TV set. I know that I will need a pass only do not know which, the monitor has input on the Dvi and vga. And I have one more question, is it possible to have some modem internet or buy something?

    Is such an adapter good? https://3.allegroimg.com/s512/030613/3375beb24b9eb26b5c4e8ece8da3

    Thank you in advance

    It's best to buy an HDMI - DVI cable and an aux cable (3.5 jack) to connect the sound.

    As for the internet, the decoder must support the WIFI usb module and the entire internet is limited to the installed applications in the decoder. You probably do not support it.

    The adapter provided by you is good theoretically, but it may not be possible to connect it. The cable is better. The audio IN jack you have in this monitor?

    If you have an HDMI cable, it is an adapter, and if it's not like the colleague above wrote.

    Welcome. You connect the antenna to the decoder, because you have a DVB-T tuner there. greetings

    If you mean, does it require a good antenna to receive anything? Depends on the location if you live in a city, you only need a room antenna and you should find a few channels, but if you have a weak signal, an external mast is required.

    And is there any way to make such a TV more enjoyable? (with this decoder) more channels, internet etc?
    I ask out of curiosity.

    I would not like to be a bad prophet, but I have some doubts.
    According to the specifications, this monitor does not support computer only TV resolution.
    It also does not support HDCP.
    You can forget about HD, the highest supported resolution is 1280x1024.

    Colleagues are 100% sure that this monitor will work with a TV decoder?

    I see that a colleague sowed a seed of uncertainty. The monitor will operate at maximum with HD 1280x720 resolution (this is how much it can handle this monitor), however, due to the fact that currently channels are broadcast in 16: 9 format, the image from the top and bottom will have stripes as in the following video.

    I have one more question if the cable (adapter) must have 24 + 1 plugs or 18 + 1 suffices? The monitor has 24 + 1.
    And what satellite jack should I buy from the antenna? I mean, is there a difference of 6.8mm and 7mm (will it fit the decoder) because I have an antenna but it lacks a plug.

    Theoretically, the 18 + 1 link should be enough, but maybe it is worth choosing the 24 + 1 to be up to future solutions with higher resolution. In such cables, the fact that it has a dual link plug 24 + 1 does not mean that these additional pins are connected to HDMI because it is Chinese and it all depends on luck they do it as they want.

    And you can advise which satellite plug for the antenna cable to buy? Because I see that there are different 7mm 6.8mm etc.

    It depends on the thickness of the cable and the connector is called the F-connector. I do not recommend such a device at home, and it collects noise by analogue.

    I was looking for something like that with screws, so you do not have to worry about the thickness of the wire.

    The only question is how the decoder will react to such a solution (and Wiwy is quite chimerical).

    So you may find that nothing will come out.

    This is the normal resolution of 720p declared by the decoder manufacturer of the problem so it should not be.
    link Most set-top boxes have something like automatically adjusting the resolution to the screen size at home in TV CRT, even 1080p I could set.
    As for 100% confidence, it never has it until it does not work itself out. The current equipment is not capricious and despite meeting the requirements it happens that it does not work though it should. As for HDCP, there is protection against high-resolution copying of materials such cheap decoders rather do not have (the decoders themselves allow you to record the material on a USB drive).

    I do not know how in this monitor, but in 19 "Fujitsu-Siemens the sound from the monitor speakers is simply hopeless (poor dynamics, poor timbre, quiet). Normal TV acoustically blinks the dvbt-monitor decoder combination. I solved the problem by putting an old cassette player behind the monitor ( connected with an ordinary audio cable with cinch plugs to the audio output of the dvbt decoder).

FAQ

TL;DR: Use an HDMI‑to‑DVI video link and 3.5 mm audio; set the decoder to 1280×720. “The monitor will operate at maximum with HD 1280×720 resolution.” [Elektroda, E8600, post #16736297] Why it matters: This turns an old DVI/VGA LCD into a simple TV using a DVB‑T set‑top box.

Quick Facts

How do I connect a set‑top box to a DVI/VGA monitor?

Run HDMI from the set‑top box to the monitor’s DVI using an HDMI‑to‑DVI cable or adapter. Route audio separately with a 3.5 mm aux lead from the decoder’s audio out to the monitor’s audio in or speakers. This delivers digital video and analog sound reliably. [Elektroda, E8600, post #16735688]

Will a Philips Brilliance 170P work as a TV with a WIWA HD90 MC?

Yes. The thread’s author reported the setup working after using the recommended connections. Expect 720p video scaled on the 1280×1024 panel and separate audio cabling. This combination provides basic TV viewing without tuner inside the monitor. [Elektroda, pytam32, post #16741407]

Should I use an HDMI‑DVI cable or a small adapter?

A direct HDMI‑to‑DVI cable is preferred for fewer contact points and better reliability. Adapters can work, but budget versions vary in quality and may fit poorly. Keep audio on a separate 3.5 mm lead regardless of which you choose. [Elektroda, E8600, post #16735688]

How do I get audio if my monitor has no speakers or no audio‑in?

Feed the decoder’s analog audio to external speakers, a soundbar, or an old stereo using 3.5 mm or RCA inputs. Users report built‑in monitor speakers sound weak, so external speakers improve clarity and volume significantly. "Normal TV acoustically blinks the dvbt‑monitor decoder combination." [Elektroda, karter, post #16739019]

Where do I connect the antenna in this setup?

Plug the terrestrial antenna into the set‑top box’s RF input. The decoder contains the DVB‑T tuner, so the monitor only handles the video signal. "You connect the antenna to the decoder, because you have a DVB‑T tuner there." [Elektroda, leszekpo59, post #16735715]

Do I need an indoor or outdoor antenna?

City locations often manage with an indoor antenna. Weak or obstructed areas benefit from an outdoor or mast‑mounted antenna for stronger reception. If channels drop or pixelate, upgrade to an external antenna and good coax. [Elektroda, E8600, post #16735732]

Can I get internet apps with this decoder and monitor?

Only if the decoder supports a USB Wi‑Fi module and has built‑in apps. Even then, functions remain limited to what the decoder’s firmware provides. Many basic DVB‑T boxes lack robust smart features. [Elektroda, E8600, post #16735688]

What resolution should I set on the decoder?

Set 720p (1280×720). The Philips 170P is a 1280×1024 panel, and 720p maps cleanly with letterboxing for 16:9 broadcasts. Most decoders let you adjust output resolution in settings. [Elektroda, E8600, post #16735895]

Why do I see black bars on the top and bottom of the screen?

Most TV channels are 16:9, while the 170P is 5:4. The decoder outputs 720p, so you’ll see horizontal bars to preserve aspect ratio. This is normal and avoids stretching faces or graphics. [Elektroda, E8600, post #16736297]

Could HDCP block the picture on this monitor?

Yes. Some older DVI monitors lack HDCP. Certain decoders or content may then refuse to show video, producing a blank screen. "So you may find that nothing will come out." This is an edge case, but be aware. [Elektroda, KOCUREK1970, post #16737511]

What is HDCP?

HDCP is copy‑protection for digital video links like HDMI and DVI. If a display lacks HDCP support, protected content can fail to play. Older monitors, including some 1280×1024 models, often omit HDCP support. [Elektroda, Polon_us, post #16735830]

My monitor’s native resolution is 1280×1024—will that work?

Yes. The decoder can output 720p, which the 1280×1024 monitor scales. Expect letterboxing due to 16:9 content. The monitor itself does not support HD resolutions beyond its panel and may lack HDCP. [Elektroda, Polon_us, post #16735830]

Which F‑connector size should I buy for the antenna cable?

Choose an F‑connector that matches your coax diameter (e.g., 6.8 mm or 7 mm). Tool‑less screw‑type F‑connectors accommodate varying cable sizes and simplify installation for beginners. Keep runs short to reduce noise. [Elektroda, E8600, post #16736579]

Does DVI 18+1 vs 24+1 matter for HDMI‑to‑DVI?

Either can work. Many low‑cost cables use the 24+1 shell, but extra pins may not be wired to HDMI. For future flexibility, 24+1 is a reasonable pick, though signal quality varies by maker. [Elektroda, E8600, post #16736501]

How can I improve the sound quality quickly?

Bypass weak monitor speakers. Connect the decoder’s audio out to powered desktop speakers, a soundbar, or an old stereo. Users noted large improvements in dynamics and loudness with even basic external speakers. [Elektroda, karter, post #16739019]

Quick 3‑step setup: monitor as TV with a DVB‑T box

  1. Connect HDMI from the decoder to the monitor’s DVI using an HDMI‑to‑DVI cable.
  2. Connect a 3.5 mm audio cable from the decoder to speakers or the monitor’s audio‑in.
  3. Power on, select DVI input on the monitor, and scan channels on the decoder. [Elektroda, E8600, post #16735688]
